RAM for laptop: how to choose

One of the most important components of the laptop, which directly affects the efficiency of its operation - the memory module. The operational storage device constantly updates the machine code, which, with each action of the processor, changes its size, then in a large side, then to a smaller one. The size and frequency of RAM is especially important when working with energy-consuming, demanding software. For example, such software includes specialized programs for working with video or images, as well as "heavy" modern games.

If the new installed "toy" refused to start on a laptop, one of the options "Fale" is an insufficient amount of RAM. To understand this, you need to know the "RAM" rating in the minimum requirements of the game (Program) and compare with the volume of the installed RAM.

How to choose the right memory

RAM parameters

It is possible to understand what the memory on the laptop can be using the AIDA64 utility. This is a powerful and wide-friendly program that has access to the hardware component of the laptop. With it, you can:

  • Analysis of the configuration "Stuffing".
  • Verification of laptop performance.
  • Find out the characteristics of "iron".
  • Trace the temperature modes of the laptop.
  • To understand what component, with what are near.

To learn all the information about the installed operational board using the AIDA64 program, you must follow the detailed instructions:

  1. Run the AIDA64 utility.
  2. Click on the "System Board" section.
  3. In the menu that opens, select "Memory", where we learn the volume.
  4. In the SPD item you can see the module name, type, serial number and other detailed information.

Consider separately each RAM parameter and we will analyze what it means and how important is for the device.

Module name

The name of the module does not particularly play roles in the efficiency of RAM, but it should be remembered, since on the Internet you can find additional data about this memory from the manufacturer. This in the future will help you learn what components it will be able to "cooperate."


Memory size

The volume of RAM is the most important energy-dependent parameter, on which the speed of operation and the overall productivity of the laptop depends. Here de facto acts the rule "the more, the better and more powerful."

Manufacturers in modern devices set minimum 4 GB and it is quite reasonable. From here it follows that all current devices use the 64-bit version of the operating system. This suggests that the laptop can handle 64 data bits at the same time. If you install the 32 bit version on the Operation of more than 4 GB, the system simply will not "see" further than its set limit. And will remain working in your format.

Type of module

There are only two types of RAM module:

  1. DIMM - RAM format, which is installed on stationary personal computers.
  2. SO-DIMM is an improved version of the previous type, installed in portable computers, ultrabooks, netbooks. It is also used to expand the RAM volume.

Memory type

RAM for laptop is divided into several types, where each chain is new versions of the previous one.

So, the types of RAM, which are used at the present time:

  • DDR is the first type that changed the prehistoric SDRAM. Compared with its predecessor, it can accelerate twice as fast. It becomes noticeable on the speed of data transfer.
  • DDR2 - This type was used from 2003 to 2010 and was a worthy "changer" of the first variety.
  • DDR3 is the following type of memory, which is characterized by lower power consumption and large prequest size (4-8 bits). There is also a variety of DDR3L, where electricity consumption is reduced by another 10%.
  • DDR4 - the fourth generation memory Double Data Rate. Actively started to be used in 2012 and is still relevant. Compared to last version, it has 16 banks, which also affects the data transfer rates.

A type

Memory speed

The data transfer rate is an important factor that the RAM is affected and in particular - its frequency. The clock frequency should have a permissible ratio with the working frequency of the motherboard bus. For example, if a module with PM 1800 were purchased, and the Mother Store supports a maximum of 1600, then such a "joint" work will lead to systemic failures and errors. Therefore, before buying the "RAM" card, check whether its laptop supports.

Voltage module

Another important factor is the supply voltage of RAM. Consider on the example, memory types:

  • DDR2 consumes 1.8 V.
  • DDR3 consumes 1.5 V.
  • DDR4 consumes 1,2 V.

Seeing these indicators, further, you need to navigate the following rule: the less power consumption, the less its heat dissipation. It follows that the board itself is less heated and the cost of cooling in the laptop is reduced.

What kind of RAM to choose for a laptop

As mentioned above, it is already mentioned to select the RAM for a laptop to be repelled from the indicators of the characteristics of the "motherboard". Each motherboard manufacturer exhibits the RAM modules comparable to it on the official website.

Manufacturer and Module Type

The following manufacturers of RAM were obtained in the computer equipment market.

  • Kingston.
  • Kingmax.
  • Transcend.
  • Corsair.
  • Samsung.
  • Ocz.

As for the type of device, there is nothing to think here. In this case, we consider laptops - it means that SO-DIMM (short micromodule) is unambiguously used here, the other is not given.

For the correct selection of the creator of the second plank (for expanding the volume), the most proven option will be the purchase of the microchip of the same manufacturer.

A type

We note again in order to select the appropriate type of memory you need to pay attention to the technical characteristics of the motherboard, which can be found on the official website.

If the main goal is to create a powerful apparatus, but within reasonable limits, it is worth using the type DDR4 or DDR3L minimum. Today, the planks of the older type are no longer relevant.


Professional programmers, system administrators and just developers choose the amount of memory for the uncommitable rule: "Memory does not happen much" or "the more, the better." And this has its own truth. But again, only if the motherboard resource will allow, well, the power supply, since the cost of energy from the power supply depends on the number of installed slats.

Therefore, before selecting a new laptop memory, it is better to determine the objectives of its use. For work and games, it is better to install RAM with a volume of at least 8 GB, and 2-4 GB is enough for domestic needs.

Memory frequency

The speed of work depends on the frequency, naturally, that the higher the frequency, the faster the device "flies". But do not forget that before choosing: you need to check what frequency supports the laptop, or rather, its main board. If the permissible frequency of the tire is less than the PM "RAM", then this will not lead to good. It should be equal or less.

In this article, I will tell you in detail in all nuances, how to choose the right memory for your laptop correctly, but first I want to warn you from rapid purchase. The fact is that the lack of RAM (hereinafter - RAM or RAM) is the very first thing for which most users are sinning when the "brakes" appears in the laptop. In fact, this is not always the case.

Better decision It will take 100% first to make sure that the cause of brakes or slow work is precisely shortage of RAM. For this, at the beginning you need to ensure that the laptop begins to slow down, i.e. Launch those programs that, in your opinion, are not enough RAM. If this is a game - then we run it if the laptop slowed down when working in a browser with a large number of tabs, then we start the browser and open all these tabs, additional programs, etc. Next, do not close, but simply turn all these programs and open the task manager:

  1. In Windows, press 3 keys at the same time: Alt + Ctrl + Del and in the menu that appears select "Task Manager". The second way to right-click on the taskbar (the bottom panel, which is the "Start" button) from scratch, select "Task Manager" from the context menu.
  2. In the "Task Manager" window below, click on "more", go to the "Performance" tab (in Windows 10 - performance, in Windows 7 - speed), in the left menu, select "Memory" (in Windows 7 I do not need to choose ).

And we estimate the level of downloading RAM. If it is almost completely loaded, as in the picture below:

RAM download level
Checking the level of downloading RAM

And the processor (CPU) is not loaded at the same time, then, most likely, the point is precisely in RAM. If you see about such a picture:

Runs and processor download level
Checking the download level of RAM and processor

That is, the memory is occupied not completely, and the processor (CPU) is 100% throws, or so (not lower than 90%) - it means it is not at all in a shortage of memory, but that the processor does not cope with the tasks assigned to it . Increasing the amount of memory here will not help.

If neither the processor nor the RAM is strongly loaded, and the laptop works all the same slowly - check the local disc with (or the other you have the operating system installed), maybe it is clogged under the string, while the computer can brake almost in all tasks. In this case, you just need to clean the C drive, as well as clean the entire system and the registry from the garbage files using specialized programs like CCleaner or the like.

If you still noticed that you lack your laptop exactly the RAM, then read on, we will deal with how to choose it and install it.

How to find out the size of the laptop RAM

There are several ways to learn the scope of RAM, the two most common:

  1. view in the "System" window;
  2. Check in Windows Task Manager.

In order to view RAM in the "System" window, you need to click on the right mouse button on the "Computer" icon (my computer) and in the appeared context menu, select the left key of the "Properties" item. This "system" window appears, in which the size of RAM will be specified:

How to find out the size of the laptop RAM
How to find out the size of the laptop's RAM using the System window

It should also be borne in mind that the 32-bit operating system is not capable of working with more than 3 GB of RAM (or rather 3.25 - 3.75 GB, depending on how much the concrete iron is eaten, for example, a built-in video card). Therefore, if you have more than 3 GB in your laptop - be sure to install the 64-bit operating system. You can see the size of the system in the same system "System", immediately after the specified amount of RAM.

If the previous method did not work, for example, you do not have a "This computer" icon on your desktop or there is a label with such a name instead (with a label to carry out these actions, it is possible), then you can determine the volume of RAM as follows: Call the Task Manager ( Alt + Ctrl + Del or right mouse over the taskbar below and click "Task Manager"), Go to the "Performance" tab (Windows 10) or "Speed" (Windows 7) in the Manager. On this tab, the total number of RAM of your laptop will be displayed.

What is the scope of RAM

The scope of RAM affects the speed of the laptop. If the memory is not enough to perform some tasks - the laptop begins to work slower, "slow down", because Instead of the missing part of the RAM, a hard disk or SSD drive begins to use.

If the memory is enough, and the laptop slows down - it means that it is not in it, and the addition of unnecessary RAM will not fix it. How to check the number of engaged in memory - it was mentioned above.

Now I will explain: the volume of RAM itself does not directly affect the speed of the computer. The speed is more influenced by the processor power, video card, permanent memory speed (for example, if the operating system is installed on the SSD drive, then the speed of the laptop will be noticeably higher than if the OS is installed on a conventional hard disk). And the volume of RAM simply should miss these components. And if you have a weak processor installed, then the increase in the volume of RAM is unlikely to affect the speed of the laptop. On the other hand, if a good processor is installed in the laptop (for example, Intel Core i5 or i7 is not older than 3-4 years), and the amount of RAM is small for it (for example - 4 GB), then an increase in the volume of RAM can give a noticeable acceleration of the laptop .

The same can be said about the video card, if it is weak - then an increase in the volume of the RAM will not give an increase in performance in games.

Therefore, with a lack of performance, first of all, you need to look in the direction of the processor, the video card (especially in the case of games), replacing the hard disk on the SSD drive. And only if you make sure your processor and the video card really cope with the tasks assigned to them, then you can think about increasing the volume of RAM.

But in any case, if there is extremely few RAM (1 or 2 GB) in the laptop, the increase in volume should be positively affected at the speed of the laptop, whatever the processor is installed.

Optimal RAM size for laptop

The optimal size of RAM depends on the processor installed in the laptop, as well as from the tasks assigned to the laptop.

If your laptop has a rather modest processor, examples from Intel:

Or from AMD:

And at the same time you do not put in front of a laptop of heavy tasks, but just sit on social networks, listen to music, watch movies, work in office programs and on sites in the browser - then the optimal size for your laptop will be 4 - 8 GB of RAM . Yes, and this processors will not always be appropriate to establish a greater volume, since they are rather weak.

If the processor is installed in your laptop just below the average, examples from Intel:

  • Pentium (starting with 4415U, 4417U, 5405U and more powerful);
  • Core i3 (starting with 8130U, 8145U, 10110U, 1005G1 and more powerful).

Or from AMD:

  • A8;
  • A9;
  • A10;
  • A12;
  • Athlon;
  • Ryzen 3.

And at the same time, you at least sometimes edit photos, video, or play not strongly demanding 3D games, or open more than 10-15 tabs in the browser and simultaneously launch several programs - then the optimal size for your laptop will be 8 - 12 GB of RAM .

And finally, if a rather powerful 4, 6, 8-core processor from Intel is installed in your laptop:

or powerful 4, 6, 8 nuclear processor from AMD:

And at the same time you also play 3D games, or you work in resource-intensive programs (video editing, 3D modeling, working with heavy 2D and 3D drawings, engage in MOUCH-design, etc.) - Then the optimal size for your laptop will be 16 GB RAM and more (Absolutely enough for any game is quite enough 16 GB, but for some heavy professional software creation programs, more than 16 GB may be needed). But if having a powerful processor, you do not load a serious laptop - then enough 8 GB .

It is also worth considering that in almost any modern processor intended for a laptop, there is a built-in graphical core (except for some Intel processors with the prefix "F", for example, Core i5-9300HF). The graphic core embedded in the processor does not have its own video memory, unlike the discrete video card (separately sprinkled on the laptop motherboard). So, a part of the RAM will be programmatically "cut off" (reserved) under the video memory for video drives.

For example, in a laptop with an AMD Ryzen 5 3500U processor, a 512 MB of 4 GB is "cut off" of the built-in video cards of VEGA 8. The system and user for work remains 3.5 GB.

If in a laptop with Ryzen 5 3500U and 4 GB of RAM to increase the volume of RAM up to 8 GB, adding a module for 4 GB, then 2 GB is automatically highlighted from RAM, and about 6 GB from 8 will remain automatically highlighted from RAM. And if you add a bar not on 4 GB, and on 8 GB (in the amount it turns out 12 GB) - the same 2 GB will be automatically allocated under the video memory, but for the needs of the user in this case, about 9.7 - 10 GB of 12 will remain.

It was a specific example with Lenovo laptop on an AMD Ryzen 5 3500U processor. Perhaps other laptop manufacturers somehow set up a reserved RAM to video memory redundant. If the Intel processor is installed in the laptop, then the automatically redundant amount of RAM for the needs of the video card may be different, depending on the generation of the processor and the built-in video card.

Therefore, before deciding what volume to purchase the RAM module, find out whether there will be a significant part of the RAM to be redundable to the needs of the video course and consider the modules with the volume of the modules in your laptop. By the way, you can sometimes be adjusted manually to the word, but on modern laptop models, this feature is more often blocked and redundancy occurs automatically depending on the established volume of RAM.

How to find out the maximum scope of the laptop's RAM

You can determine the maximum amount of memory supported by your laptop model using the AIDA64 program. It has a 30-day free limited version, but for our purposes this is enough. Swing the program only from the official site - https://www.aida64.com/downloads.

How to download the program AIDA64 Extreme
Download the AIDA64 EXTREME program from the official site

Next click on the download.aida64.com server, or for some other if this server is not available.

Server selection when loading AIDA64
Select the server download.aida64.com

We install, run, go to the "System Board" section - "chipset".

We look at the maximum scope of the laptop's RAM in the AIDA64 program
The maximum amount of RAM Notebook in the AIDA64 program

In this example, the laptop officially supports up to 16 GB of RAM. Also, the most supported volume of RAM can be found on the official website of the laptop manufacturer, in the technical characteristics of the model or series of interest or series (some manufacturers do not provide detailed characteristics of a specific model of a laptop, but provide characteristics by the series as a whole - all variations in the series in the series, all possible options configuration of memory, etc.).

It should be understood that the manufacturer's maximum amount of RAM is the volume that the manufacturer tested in this laptop and guarantees the operation of the laptop with the specified volume. As a rule, the specified maximum volume is set by the manufacturer from the factory into the richest and expensive complete set of this series.

But in practice it often happens that laptops can work with a large volume than the manufacturer indicated. You can learn either on the Internet - on forums, in reviews, in blocks of questions and answers of some online stores, such as cylindes or DNS / Technopointe, or experienced by. But buying an operational memory for the sake of the experiment is not reasonable, but suddenly will not "start up", you will have to get a memory back, and here difficulties may arise ... Therefore, some users go straight to the store with their laptop and agree with the sellers, to check for compatibility before buying them. New memory (more volume than officially supported). Sometimes sellers go to a meeting with customers and allow you to check the compatibility of memory with a laptop, because it is beneficial to sell more memory, because it is more expensive.

Check is performed very simply - insert memory, turn on the laptop. If turned on, the operating system sees the whole volume of RAM and the laptop works normally - it means "started", you can buy. If it did not turn on - then you should try modules from another manufacturer with the same volume (and preferably with the most similar timings, as in the already installed memory). If the memory does not start from another manufacturer, then perhaps not fate ... Try the modules of a smaller volume.

If a separate small lid is provided to replace RAM in a laptop, then checking one module or modules set of 2 pieces takes less than 5 minutes. But in most modern models for the sake of saving ceased to make individual shells to replace RAM and hard disk / SSD. In this case, you have to unscrew and remove the entire bottom cover (about 15-20 bolts), then the check can stretch for 15-20 minutes. The bolts themselves are unscrewed fairly easily and quickly, but quickly and gently shake around the perimeter of the cover all the latches so as not to leave the visible traces of the parsing - a little problematic if the "hand is not packed." It is better not to do this in order not to break the latches, and preferably a plastic object, and not a metal, such as a plastic card. It is better to first look at YouTube how your model of a laptop or a similar model is precisely described in the same series.

What kind of RAM to choose for a laptop

RAM for home computers and laptops is two form factors (roughly speaking - sizes):

  • Dimm. - for stationary computers;
  • Soft Dimm. - For laptops (also used in monoblocks).
Comparison of two RAM Forms: DIMM (for PC) and SO-DIMM (for laptop)
Visual comparison of two RAM form factors: DIMM (for PC) and SO-DIMM (for laptop)

As can be seen in the picture, the SO-DIMM memory plan is much shorter than the DIMM bar, so they are not interchangeable.

So, for a laptop, we choose only modules Soft DIMM. But this is not all that you need to know about the choice of RAM for a laptop, as there are still various generations and other nuances.

Generations of RAM

RAM, in addition to the form factor (size), differs in generations:

  • DDR4. (appeared in 2014) - the most modern type of RAM is installed in all modern laptops;
  • DDR3 (appeared in 2007) - the older generation is not installed in new laptops, but quite often meets in used laptops, has a partially compatible variety - DDR3L (this is a version with reduced energy consumption of 1.35V, instead of 1.5V in DDR3, it is still Until now, you can meet in modern budget models of Acer laptops);
  • DDR2. (appeared in 2003) - this is a completely ancient type of RAM, acquire used laptops with such memory I do not advise, because Laptops with DDR2 are very old and slow technique, and how much they still will last - it is unknown.

There are even older generations, but you can hardly meet them, so we will stop on the listed.

Each new generation is faster than the past, and also consumes less energy, which has a positive effect on the time of the laptop from the battery (though, the difference is not very big). All these generations are not compatible with each other, that is, if the DDR3 memory is installed in your laptop, then install DDR4 or DDR2 does not work into it, all generations have different keys (special slot in the contact group), which are simply physically not allowed to install the planks In the connector of the non-appropriate generation.

Comparison of RAM generations
Visual comparison of mining generations

Regarding the compatibility DDR3 and DDR3L I would like to give one advice. In the network you can find information that DDR3 and DDR3L are fully compatible. But in practice, people often encounter the fact that these varieties of RAM are not compatible. For example, DDR3 modules require 1.5V voltage, and inserting them into a laptop, designed only to work with DDR3L (1.35V), such a module can simply not have enough voltage and the laptop will not turn on. If you do vice versa, i.e. In a laptop, designed to work with DDR3 (1.5V) insert the DDR3L module (1.35V) - then it can be done normally (after all, many DDR3L modules are able to operate both at a voltage of 1.35V and at a voltage of 1.5V), and may not Earn ... In general, the Council is such - first find out which type of memory is installed in your laptop (DDR3 or DDR3L), and then buy a module of the same type as already installed in the laptop.

How to see a generation of RAM

In order to see what generation is installed in your laptop, it is not necessary to disassemble it at all, you can use the task manager in Windows 10 or special programs if you have an older version of Windows.

How to go to the task manager was described earlier (via the ALT + CTRL + DEL key combination), so we go to the "Performance" tab, select "Memory" in the left menu.

As we can see in the screenshot above - in our laptop the memory of the DDR3 standard is installed, you can also be installed by the RAM of another generation. Sometimes task dispatcher for some reason does not display generation and have to resort to third-party programs.

One of the most popular free programs for these (and not only) goals is CPU-Z. , You can download it by reference from the official site - https://www.cpuid.com/softwares/cpu-z.html.

Download, install, run and go to the MEMORY tab, here in the first line in the "Type" field will be indicated, for example, "DDR3".

How to see a generation of RAM in CPU-Z
Generation of RAM in CPU-Z

It means that the DDR3 standard memory is installed in the laptop (not confused with low-voltage DDR3L), and to increase the amount of memory you need to purchase exactly this generation. Accordingly, if specified - DDR4, then we purchase the memory of only DDR4 standard, etc.

Each of the standards: DDR2, DDR3, DDR4 - can work at different frequency, so to correctly select RAM for a laptop, it is not enough to know only the desired generation.

At what frequency the memory works

The generations listed earlier support the following frequencies:

  • DDR2. - from 400 MHz to 1066 MHz (the most popular and frequently found modules are 800 MHz).
  • DDR3 - from 800 MHz to 2133 MHz (most popular and frequently encountered modules - at 1333 and 1600 MHz).
  • DDR4. - from 1600 MHz to 3200 MHz (most popular and frequently found modules - at 2133, 2400 and 2666 MHz).

* In the PC, the frequency of the DDR4 modules can reach 4600 MHz.

How to find out the frequency of RAM on a laptop

To determine the frequency at which the RAM is currently working, you can use the Task Manager in Windows 10. On the "Performance" tab in the left menu in the memory point, the frequency is indicated as "speed", an example below.

How to find out the frequency of RAM on a laptop in the Task Manager
Current RAM frequency in Task Manager

What does "current frequency" mean? Modules can be installed, for example, by 1600 MHz, but the RAM can work at a reduced frequency, for example, 1333 MHz (there may be several reasons for this, then talk about it). The dispatcher shows not the maximum (native) frequency of the modules, but the current frequency at which the RAM is currently running.

To find out the maximum frequency supported by the memory modules installed in the laptop, you can use the CPU-Z program. Go to the "SPD" tab and in the Max Bandwidth column in brackets, the maximum frequency of the selected module that it supports will be specified. Similarly, it is worth viewing information and other modules if they are installed (Slot # 2, etc.).

How to find out the frequency of the laptop's RAM in CPU-Z
Maximum frequency of RAM module in CPU-Z

It is worth clarifying that CPU-Z shows us Real Frequency, and manufacturers on their memory modules indicate Effective Frequency. The current efficient frequency shows us the task manager in Windows. And in general, when it comes to the memory frequency - it is almost always an effective frequency (real * 2). Such a confusion occurs because the clock impulses go with a frequency of 800 MHz, but the data is transmitted 2 times for each pulse. Marketers could not use it and in pursuit of large numbers began to specify not real, but an effective frequency.

Let's wonder on our example. To transfer the real frequency to efficiently, you need to multiply it by 2, that is, in this particular case, seen in CPU-Z. In the Count "Max Bandwidth" 800 MHz multiply on 2 and we get 1600 MHz (the effective frequency we saw in the task manager). It is with such a frequency (1600) and we buy an additional memory bar.

If we saw a lower frequency in the task manager than the modules support, it means that something prevents our modules to work at the maximum possible frequency.

In order to make sure that RAM really works on a reduced frequency, go to the MEMORY tab and look at the "DRAM FREQUENCY" parameter.

How to view the real current frequency of RAM in CPU-Z
Current RAM frequency in CPU-Z

If everything works fine and there are no restrictions, then the "DRAM FREQUENCY" parameter (current frequency of RAM) must roughly coincide with the Max Bandwidth parameter on the SPD tab. Current frequency slightly floats (varied dynamically), therefore such errors (798.1 MHz instead of 800 MHz) are quite acceptable. But if you have, for example, instead of the 800 MHz, supported by the module (specified in Max Bandwidth), RAM operates at a frequency noticeable below (if the "DRAM FREQUENCY" parameter is noticeably lower), say, 533 MHz, then this is not there Well, you need to look for the cause and understand why RAM works at a slower frequency than the module (s) is supported. And the reasons usually may be three:

  1. The BIOS simply does not configure the memory frequency. It often happens that by default BIOS does not set the maximum frequency that modules support, and sets the frequency to minimal and you just need to go to the BIOS and adjust the frequency correctly (it is rather relevant for the PC than for modern budget laptops, not at all budget Laptops can be set up the frequency of RAM).
  2. Perhaps some of the other modules in your PC / laptop has a lower frequency - 533 MHz (efficient 1066 MHz), it means that this module will automatically cut to the frequency of 533 MHz (effective 1066 MHz). The frequency is always automatically set to the same on all modules by the smallest (by the slower module itself, because at a higher frequency it cannot work, and they all have to work synchronously at one frequency).
  3. The 800 MHz frequency (efficient 1600 MHz) does not support the processor / chipset, so it is cut to supported by the processor / chipset, namely 533 MHz (effective 1066 MHz).

It should be remembered that the memory frequency is not the only indicator of its speed. There is such a parameter as timing (delays), and what they are less - the better.

How to watch timings (delays) RAM in CPU-Z
Timing (delays) of RAM in CPU-Z

For example, one module has timings 11-11-11-28 (CL-RCD-RP-RAS), and the other 13-12-12-32, and the frequency, and the volume of modules - the same, in which case the first module ( 11-11-11-28) will work a little faster. You should also know that the rates of timings increase with increasing frequency. For example, DDR3 memory, in general, has frequencies lower than DDR4, but also timings in DDR3 below. But all the same higher frequency is more important than lower timings, therefore DDR4 is faster than DDR3.

RAM for laptop different frequency

Acquire the memory of preferably the frequency on which the laptop already installed in the laptop is running (if you are going to leave the old memory bar and buy a new one to it). The fact is that if in the laptop to install a memory plank with different frequency, then they will work at the frequency of the slower plank . That is, for example, the DDR3 1333 MHz module was installed in your laptop, and you bought and installed a pair of a DDR3 1600 MHz module to it, in this case both modules will work at a frequency of 1333 MHz. Therefore, overpay for a higher frequency of meaning no (although they are almost at one price). And if, for example, you had a module for 1600 MHz, then buy an additional slower module for 1333 MHz, the more not worth it, because then the "native" module for 1600 MHz will start working at a lower frequency of 1333 MHz.

If you decide to remove all old planks from the laptop and replace them with new ones, then you can take modules with a maximum frequency supported by the processor / chipset, it will give some speed laptop. For example, a module with a frequency of 1333 MHz was installed in your laptop. You go to the official website of the laptop manufacturer, find your laptop model (or series, if specifically there is no information about this model) and see in the characteristics that the maximum supported frequency of RAM is 1600 MHz. So new modules are best bought precisely with a frequency of 1600 MHz.

Also, this information can be found in technical support on the manufacturer's official website. As an option, you can see using the AIDA64 program, in the "System Board" section - "chipset".

Supported Memory Types Laptop: DDR3-1066 / 1333/1600/1866
Learn what memory you can support the laptop in the AIDA64 program

As we see from the screenshot, in our case, the memory DDR3-1600 is supported and even supported by a faster DDR3-1866 (although I'm not sure that modules with a frequency of 1866 MHz really will earn in this laptop, but 1600 MHz modules work well).

If suddenly you acquire modules with a higher frequency than supporting the processor / chipset, then with a large probability, such memory will still earn in a laptop, but at a lower frequency, or rather to the one that the processor / chipset supports the processor. But overpayment for faster memory in this case will be meaningless.

Attention: There are cases when when installing memory with a higher frequency than the previous one, the laptop generally refuses to start. So you encountered incompatibility. In this case, new memory planks with a higher frequency exchange to others, with a lower frequency, and preferably from the same manufacturer as old (already installed in the laptop). In some cases, the flashing saves BIOS to a more recent version.

How to see how many RAM schedule installed

In laptops there are the following embodiments of RAM, will begin by the worst to the best:

  1. Only operative memory on the motherboard without additional slots to add RAM modules. Such implementation is common, as a rule, either in the cheapest laptops or in compact and subtle ultrabooks, which, oddly enough, can cost no small money. This is the most unsuccessful implementation of RAM, because it will not work in the amount of RAM in this case.
  2. Only one slot for the RAM, in addition to it, there is no second slot or the dispersion memory. This option is slightly better than the previous one, because in this case the volume of RAM, if desired, can be increased by replacing the only module to more capacious. But still, this is not the best embodiment of RAM, since without a second module (wriggled or installed in a slot) RAM will never work in two-channel mode (memory bandwidth in two-channel mode is 2 times higher). It is especially sad when this implementation is found in gaming laptops, even if there is a good video card and processor, due to a single-channel mode, in some games will periodically slip frills and twisting.
  3. A part of the RAM RAM on the motherboard, and in addition to it, it has a just one slot to add a RAM module. Such a realization of RAM is very often found among laptops in a low and medium price segment. Not the worst, but not the best option, because, first, the sawn memory limits the maximum amount of RAM (as a rule it is 20 GB - 4 GB of smokery + module for 16 GB, but in some cases it can be more - 4 GB Plain + 32 GB module). Secondly, the frequency of the displayed memory limits the frequency of the second strip (for example, if the displayed memory is a frequency of 2133 MHz, the module mounted to it will be able to work at a maximum of 2133 MHz, even if the module itself supports work at a higher frequency).
  4. Two slots under the modules of RAM, there is no smoking memory. This is one of the best embodiments of RAM in a laptop, since in this case, as a rule, up to 32 GB of RAM (2 modules of 16 GB) can be installed. What is all 32 GB in this case will be able to work in two-channel mode. The maximum frequency will be limited to the capabilities of the chipset and processor.
  5. Four slots under the modules of RAM, there is no accession. Such a realization of RAM is found in laptops extremely rare, mainly in a very expensive series.

In order to see how many RAM schedule is installed, you can use the task manager in Windows 10. On the "Performance" tab, in the "Memory" menu item, we find the phrase "Used Nests" and see the value opposite.

2 RAM strips have been installed, all the existing nest under RAM (two)
See how many RAM Planks are installed in the Task Manager

In fact, in this laptop (on which this screenshot was made), one of the modules on 4 GB is placed on the motherboard, in addition, on the board there is only one slot for the installation of RAM, into which the manufacturer has already installed a module for 4 GB ( Total 8 GB). This is how the RAM (4 black chips) is written on the motherboard.

Smokey memory on the motherboard
Screen RAM on a laptop

From above to the only slot by the manufacturer, another plank on 4 GB was inserted:

One straightfight of the RASTAGO RAM, the second is installed in the only slot
Installed Blue Rams Plank in the only slot

This solution has a few minuses, some have already been mentioned above, but we will still repeat to fix the material:

  1. If the RAM module is discontinued on the motherboard, it will not be possible to replace it independently, you will have to carry a laptop into a service center and overpass the memory chips.
  2. If we want to increase the speed of RAM and put a bar in a laptop with a higher frequency, then, alas, it will not work. Rather, it is possible to put a bar with a higher frequency, but it will work at the frequency of the already dispecified module, but not higher. It is possible to increase the speed will be able to overclock the memory, but this is a completely different story, and indeed on all laptops it can be done.
  3. More modest possibilities for increasing the amount of memory, as we can replace only one module to more capacious.
  4. The amount of dispersion memory toughly limits the total RAM volume, which can operate in two-channel mode (with a two-channel mode, the memory bandwidth is increased by 2 times). For example, we have 4 GB on our motherboard, it means that in two-channel mode, we can work with a maximum of 8 GB, regardless of which volume we will deliver an additional module. For example, if we deliver the module on 4 GB, then in two-channel mode all 8 GB will operate (4 GB of splashing + module on 4 GB). If we deliver the module on 8 GB (in the amount it turns out 12 GB - 4 GB of the splashing + module on 8 GB), then in two-channel mode, only 8 GB will also work (4 GB of splashing + 4 GB from the module), the remaining 4 GB from the module will Work in one-channel mode. If we deliver a module on 16 GB (in the amount it turns out 20 GB - 4 GB of the splashing + module for 16 GB), then only 8 GB (4 GB of splashing + 4 GB from the module) will also work in two-channel mode (4 GB of splashing + 4 GB from the module), the remaining 12 GB from the module will Work in one-channel mode. And so on ... But if we deliver the module for only 2 GB, only 4 GB (2 GB from the module + 2 GB of the sawn memory) will operate in two-channel mode), the remaining 2 GB of dispersion memory will operate in one-channel mode. I think you guessed how to calculate the volume of RAM, capable of working in two-channel mode - we take the container of the smallest module and multiply on 2.

Task Manager In part, it turned out to be the right that there are no free nests under RAM, but it's misleading, showing that we have 2 nests on the board.

CPU- ZWith this task, I coped even worse and showed erroneous data, although at the time of writing the article was installed the most recent version from the official site. On the SPD tab, there is a drop-down list with slots, an example in the picture below.

Information about the first slot of RAM - installed a plan for 1600 MHz
Information about the first slot of RAM in the CPU-Z program

We see that in our case there are 2 slots under RAM in a laptop (the same error as in the Task Manager, the physical slot we have one). When choosing a first slot, the program displays that it is installed in a 4-gigabyte DDR3 Plank (4096 MBYTES) with a real frequency of 800 MHz (or 1600 MHz efficient). But when choosing a second slot, we open the following picture:

Information about the second slot of RAM - data is missing
Information about the second slot of RAM in the CPU-Z program

This should mean that the second slot is free and an additional module can be installed in it, which, of course, is not true.

Popular program Aida64. Also does not give us accurate information on the number of slots. In the section "System Board" - "chipset" we see that in a laptop, allegedly, there are 2 slots and the planks of 4 GB are installed in both (in fact, one of them is planted, and not inserted into the slot).

AIDA64 indicates to us that in a laptop 2 connectors under RAM
Data on memory connectors in AIDA64

At the same time, in the "System Board" section - "SPD" displays only 1 plank (the one that is inserted into the slot). The displaced memory module is not displayed.

AIDA64 shows information only by one RAM strip
Data on RAM planks in the AIDA64 program

As we have seen earlier, when the memory barrier is planted on the motherboard, the program cannot correctly determine the amount of empty slots under RAM, thereby misleading the user. Indirect signs of built-in memory are the lack of information on one of the modules.

The most correct solution to understand how many memory schedule is installed and there are empty slots - remove the cover under which the RAM modules are located, and watch "live". Often, a separate small lid on several screws (or even one) is provided to replace RAM and hard disk (or even on one), which, if there is a screwdriver of the appropriate size, it is easy to remove. How to disassemble specifically your laptop model is better to look at YouTube.

Best RAM Manufacturers for Laptop

Let us immediately explain that in RAM, the main elements stored by the information are stored, memory chips are. On the module they are sprinkled by several pieces, sometimes on both sides.

On each RAM bar dispersion of memory chips
RAM chips are shown by arrows

So, the manufacturers of RAM are divided into 2 camps:

  1. Memory chip manufacturers (some of them produce and the memory modules are entirely based on their own chips);
  2. Manufacturers of memory modules that independently produce chips, and buy ready-made first.

The first camp that produces chips on their own includes such companies as:

  • HYNIX (Hyundai);
  • Samsung;
  • NEC;
  • Toshiba and others.

Some of them, for example, Hynix and Samsung - not only sell their chips to the manufacturers of RAM modules, but also produce modules of RAM under their brand.

To the second camp, which is purchasing ready-made memory chips and the producing plank based on them include companies such as:

  • A-DATA;
  • AMD Radeon;
  • Corsair;
  • Kingston (Hyperx);
  • Patriot;
  • Silicon Power;
  • TRANSCEND, etc.

That is why, by purchasing, for example, a memory module from Corsair, you can detect memory chips with the inscription "Samsung". In fact, the company from the second list is just the collectors, some of them do not even produce printed circuit boards.

Despite this, high-quality memory modules can be found both from companies from the first camp and from the second. The main thing is to acquire modules from well-known firms, as well as before purchase, be sure to ask if there are no negative feedback on the specific selected model of RAM.

From myself I can recommend RAM, first of all, from chip manufacturers: Hynix and Samsung, as well as from companies: Kingston (Hyperx) and Corsair. Also, it was also necessary to deal with Patriot planks, according to my observations with reliability they do not have bad, but now the stated frequencies are sometimes not kept (concerns high-frequency slats, about 3000 MHz) and it is strange, why was there such frequencies on their planks ...

Who is interested in familiar with the "collectors" of memory modules in more detail and find out what memory the company uses, here is the link to Overclockers.ru.

How to increase the amount of RAM on the laptop

So, in order to increase the amount of RAM, it is necessary to clearly understand:

  1. what Form factor modules are required (for laptops is SO-DIMM);
  2. what generation Memory needs to be purchased - DDR2, DDR3 or DDR4 (depends on the processor and motherboard of your laptop);
  3. What modules Frequency You need (preferably acquired with the same frequency as the current modules already installed in the laptop);
  4. Modules of some volume You need (in order not to exceed the maximum allowable amount supported by the memory controller);
  5. what Manufacturer RAM should give preference.

After the necessary RAM will be purchased, it will need to be installed in a laptop. This can be done independently (if it is not clear how to do it - I advise you to watch the video specifically on your Laptop model on YouTube), or for a small fee in the service center. Sometimes, (if you ask well) it is done for free right in the store, where the RAM modules were purchased.

Below is the video, how the RAM is changing on most laptops (but this does not mean that in your laptop it changes in the same way, I am better - it's better to find the video with a particular laptop model or at least with disassembling the laptop of the same series).

What else needs to know about the RAM

When installing slats, not one set can be encountered with the incompatibility of memory modules. It happens quite rarely, but still it happens, and determine in advance whether the memory bar will be compatible from different sets - it is impossible. If memory modules have different characteristics - frequency, timings, etc., or they are from different manufacturers - then the chances of incurred by incompatibility increase. Therefore, it is better if the planks are from one manufacturer and with the same characteristics. And ideally, the memory is from one set. In stores you can often find ready-made memory sets for 2 and 4 bar, in which case the manufacturer ensures that all the planks from the kit will be 100% compatible with each other.

RAM kit for laptop
This looks like a set of RAM for laptop.

But the kits, as a rule, are a little more expensive, so I personally buy just two planks of one manufacturer, one model (with the same characteristics) and immediately in one store in one day. This increases the chances that these planks were produced approximately at the same time from the same components. After all, it happens that today the manufacturer collected a plank from some components, and tomorrow concludes a more profitable deal with the supplier of other components and, roughly speaking, the next day begins to release the same model of RAM, but on other components. And in such slats, with different components, incompatibility may already arise (although the model at the planks is the same). Therefore, per 100% insure itself from the incompatibility of modules, you can only buy the planks with a set.

But in my practice when buying the same piece models of planks in one store in one day - I have never run into incompatibility, so all this is the case of the case ...

The requirements of programs to the volume of available memory are growing with each month - each new version requires memory more and more. Often the situation when a laptop, a couple more years ago perfectly coped with my tasks, today mercilessly "slows down". Perhaps the case is in unnecessary services and unnecessary automatically launched programs; Perhaps the computer was swinging on the computer. But if the antivirus does not find anything, and the cleaning and reinstallation of the system do not help, then perhaps the problem is in the disadvantage of RAM. How to find out that it is in a shortage of memory?

Windows: Linux: OS X:

The total volume (red frame) is given in MB, and free memory (green frame) - in% (starting with Windows Vista)

Common and free amounts of memory are displayed in kilobytes, Free -M should be used to output.

OS X demonstrates high visibility and details of the provision of information even in standard programs.

In Windows - using the Task Manager caused by the Ctrl-Alt-Del keyboard. In Linux, you can use the FREE program, and in OS X - the system monitor ("programs" - "utilities" - "Monitoring system").

When free RAM tends to 0, the system begins to use the paging file - part of the data is transferred from memory to the hard disk. The speed of working with a hard disk to orders is lower than with the RAM, so the access to such data can "suspend" a computer for several minutes to perform an operation that usually takes no longer a second. You need to increase the amount of memory.

Windows: Linux: OS X:

The memory type and frequency of the installed module can be seen on the SPD tab. The number of free and busy slots can be found by calling the drop-down list of Memory Slot Selection

Dmidecode shows the number of slots, type and speed for each busy slot and marks the phrase "No Module Installed" every free slot.

Information minimum, but this is enough to buy a new memory module

First of all, you should make sure that the laptop has a reserve for its increase. To begin with, refer to the description of the laptop on the manufacturer's website (or to the instruction manual) and find out what is the maximum amount of memory for your model. If the memory capacity reserve is available, you need to make sure that there are free slots for memory modules in a laptop. On OS X, this can be done with standard means - using the "Memory" tab of the "System Information" window. In Linux, you can use the Dmidecode program (enters most of the repository). For Windows, the choice of suitable programs is large, but many of them are not reflectable. From free, you can recommend CPU-Z.

Of course, you can simply open the memory cover and see if there is a free slot there. But, first, it is not always possible (for example, if a laptop is still on warranty and the cover is sealed by a warranty sticker). Secondly, the information obtained using these programs will be needed when purchasing new memory modules, because the main characteristics (memory and frequency type) of the new modules must match the characteristics of the already installed. For some laptops it is necessary to coincide and the rank (the number of logical memory modules inside one physical) memory modules. To enable two-channel mode (speeding up memory), it is desirable to coincide and the capacity of the modules. It is also desirable that new and old modules have identical timings (about them further) and even the manufacturer. Failure to comply with the last requirement may not affect the operation of the system, and maybe lead to various failures and "glitches" - how lucky. And in general, the more similar to the installed memory blocks, the higher the chance that the laptop will turn on and will work without problems.

What to do if there is no free slots of memory, and there is a reserve for magnifying the model? Sell ​​available memory modules and buy new, greater. The same option can be recommended if there is a free slot, but the identical installed module cannot be found. When buying a new set, you are not entirely related to the requirements of the old memory module and you can select models with improved characteristics.

Please note that 32-bit versions of Windows do not support more than 3 GB of RAM. Therefore, if you are going to increase memory from 2 to 4 GB, and you have a 32-bit version of Windows, it will not be necessary before purchasing memory to try to install the 64-bit version and make sure that the laptop and all the peripherals work correctly with this system.

Characteristics of memory modules.

Form factor Memory modules for laptops One for all types - SO-DIMM.

Memory type . When buying an additional module, the type of memory must necessarily match the memory type already installed. When buying a set of the whole - the higher the type (DDR - DDR2 - DDR3 - DDR4), the higher the speed of memory and below power consumption. But again, it is necessary to make sure (learn from the documentation or description on the website of the laptop manufacturer) that the selected memory type is supported by the laptop.

From this chain, DDR3L is slightly knocked out. This type of memory is completely identical to DDR3, but has a reduced 10% power consumption. For laptops, this is quite important, since the lower power consumption, the higher the duration of the battery. Therefore, choosing between DDR3 and DDR3L, it is better to stay on the latter (of course, subject to the support of this type of memory with a laptop).

Frequency - Another important parameter of RAM, which directly affects the speed of working with memory. The higher the frequency, the better, but, first, the frequencies of all installed modules must coincide, secondly, the frequency must be supported by a laptop.

Memory size . Software requirements for the amount of memory are growing all the time, so the recommendations for the required amount of memory are quickly obedized. To date, 2 GB is a minimum, sufficient for the normal operation of office applications (Word, Excel) and Internet access. For the full use of graphic packages like Photoshop or CorelDRAW, viewing video in HD format and undemanding games will be enough 4 GB of memory. A full-fledged gaming laptop will require from 8 GB of memory as a professional workstation to work with video or 3D scenes.

Timing - Delays in memory access, are considered in frequency tacks. Main timings:

Cas Latency.

Ras to Cas Delay

- CAS LATENCY (CL) - Delay between the query to a specific memory block and the beginning of receiving / data transmission. This parameter is the most characteristic, for DDR3 its value should be 9-11, depending on the frequency; For DDR4 - 15-16. Large latency values ​​are undesirable;

- Ras to Cas Delay (TRCD) - a delay between the definition of a string and a column with the necessary data (the memory is organized in a tabular form and to obtain certain data you need to transfer the row and column numbers)

- RAS PRECHARGE (TRP) - the final delay after operation with data before the next operation.

In memory characteristics, timings are often recorded as CL-TRCD-TRP. For example, 5-5-5. The smaller the timing, the memory is faster, but only the same type of modules should be compared according to this parameter. With increasing frequency, the timings are inevitably growing, and the timing of 15 for a module with a frequency of 2400 MHz along the delay duration is compared with the timing 5 for the frequency of 800 MHz (1/2400 * 15 = 1/800 * 5).

Placing chips. Memory chips (microcircuits) on modules can be placed both from one and on both sides. This does not affect the memory characteristics, but it is necessary to pay attention to this: modules with double-sided chip installation have a greater thickness and may simply not fit into a free slot.

If you decide to update all RAM, pay attention to Sets of RAM consisting of 2 or 4 modules specifically selected to ensure memory work in two- or four-channel mode. Two-channel mode speeds up work with memory due to the possibility of simultaneous access to two memory areas located on different modules. Theoretically, such a mode must accelerate the work with memory twice, but practically productivity growth ranges from 5 to 15%. For memory operation in two-channel mode, it is necessary that the laptop motherboard supports such a mode (implemented in all modern motherboards) so that the memory modules have an even number and that they are identical. Although usually a two-channel mode is activated on the memory modules without any problems, buying a memory set is a guarantee of including this mode.

Manufacturer. The production of RAM is a high-tech process that requires the highest culture of production and modern equipment. The percentage of marriage is present at any manufacturer, but only industry flagships are able to provide a low percentage of marriage and its timely identification. Buying memory of a little-known manufacturer - always Lottery: If you are lucky, the memory of faith and the truth will work years, demonstrating quite good characteristics. If not lucky, and the defective chip will fall, then it is not a fact that you can change it under warranty: Marriage of memory can lead to hard-looking mistakes that arise randomly or only under certain conditions. Therefore, if you are important, stable and productive memory work, take the modules of verified manufacturers, such as AMD, Corsair, Crucial, Transcend, Kingston.

Selection options.

If you wish to "peck" 2 GB to two available for upgrading your laptop, choose among single 2 gigabyte modules of verified manufacturers. Do not forget to find out the type and frequency of the already installed module and choose identical. It will cost you at 930-1350 rubles.

If you need a memory that lasts a long time, buy the modules of proven manufacturers with a warranty period of 10 years - this term is more than enough and for sure the new memory you will need earlier than the warranty period will be. Such modules will be from 1150 rubles per 2 GB.

If you need a set of high-speed memory for a gaming computer with a guaranteed dual-channel mode support, select among the relevant RAM sets. Such a kit will cost you from 4050 rubles for 8 GB.

Violating the work of the entire computer system is easy - just to choose and install an inappropriate RAM module in a laptop. For the correct selection of RAM for laptop, it is important to take into account not only the parameters of the processor and the system board, but also installed by the manufacturer of the module.

How can I find RAM on a laptop

If, performing a laptop upgrade, you need to increase the volume of RAM, then first of all, find out which prompt model is installed on your device.

To determine the type of RAM, which is installed in your laptop, it is best to use the CPU-Z program.

  1. Download the official version And install the utility.
  2. After starting, you must select the item called "SPD "

After that, the utility will display detailed data on your RAM.

Parameters that are of great importance when selecting RAM for your laptop are highlighted in red.

If you do not want to understand all the subtleties of RAM for laptops, but you still need to replace or purchase additional scope, then the best solution will get the module from the laptop and go with it to the store, where the competent manager will pick you up the best option .

Optimum volume

What is the size of the RAM to choose and what is suitable for a laptop? It all depends on the tasks assigned to the laptop and installed in the processor device. Consider a couple of examples.

You use some modest and inexpensive processor from Intel:

Or from AMD:

At the same time, your laptop does not perform some difficult tasks, you just watch movies, listen to music, sit in social networks and work in office programs. In this case, it is recommended to buy an RAM module from 4 GB to 6 GB for a laptop.

In addition, to set large volumes of RAM to the processors described above are not appropriate, as they are too weak. They simply do not have enough power to use all the advantages of such sizes.

The second example. On your laptop - Intel mode of medium power processor:

Or from AMD:

At the same time, you have time from time to time to modern 3D games, edit videos or photos, and sometimes open more fifteen tabs in the web browser with another simultaneously running software. In this case, the best option for your laptop will be the purchase of RAM from 8 GB to 12 GB.

If you are a happy owner of such powerful processors as AMD Ryzen 7 or Intel Core i7 and at the same time, you work in heavy programs, play modern 3D games - buy 16 GB of RAM for your laptop.

At the same time, if you do not load your expensive processor in any way - it will be enough 8 GB of RAM.

Best manufacturers

RAM manufacturers for laptops are quite a lot. How to choose additional laptop RAM in this case?

To begin, it is necessary to immediately note that the main component of any RAM is the memory chips that store information. On the RAM module, they are usually unpacked by a couple of pieces.

But back to manufacturers that can be divided into two categories:

  1. Companies of RAM microcircuits, which sometimes produce and full-fledged RAM modules on the basis of their chips.
  2. Companies that do not produce chips independently, but buy already ready for the first category of manufacturers.

To date, the following well-known companies are released independently:

  • Hynix (Hyundai).
  • NEC.
  • Toshiba.
  • Samsung.
  • Micron.

At the same time, Samsung and Hynix are also released under their brand also RAM modules.

Companies that buy already ready-made RAM chips and based on them produce their planks:

  • A-DATA.
  • Kingston (Hyperx).
  • Patriot.
  • AMD Radeon.
  • Corsair.
  • Silicon Power.
  • Transcend.

Thus, if you bought a Silicon Power RAM module, but suddenly discovered memory chips on it with the inscription MICRON, do not be scared. This is normal.

Companies from the second list are only collectors. Many of them do not even produce printed circuit boards for RAM modules.

However, high quality can be found both from manufacturers and from the collectors. Home Recommendation - Buy Modules of RAM for laptop only from well-known firms, and read about them reviews on the Internet, there are no secret negative nuances with the specifically chosen model you.

Other important features when choosing

Pick the RAM based on the following parameters.


For all laptops today uses only one form factor of RAM modules - SO-DIMM. . In addition to the form factor, RAM differs in its generations:

  • DDR4 (year of appearance on the market - 2014) is the most new RAM. It is this operational memory for a laptop is set to all modern devices. Therefore, choose the RDR4 RAM.
  • DDR3 (year of appearance in the market - 2007) is an older type. It is not installed in new laptops, but it is often found in used laptops. It is worth noting that DDR3 has a compatible variety called DDR3L. It is characterized by reduced energy consumption, which may not matter for a personal computer, but it is important for a laptop.
  • DDR2 (year in the market - 2003) is a very old type of RAM. Laptops with such memory are ancient and slow technique. Therefore, to acquire such devices is not recommended.

The new generation of RAM is not always much faster than the past, but always consumes less energy. It is very important for portable devices. It is important to understand that all these generations of RAM are not compatible with each other. Therefore, if your laptop works on DDR3, then install DDR2 or DDR4 there will fail.


Another important parameter is the frequency. First of all, it is important to understand what it is higher, the better.

The above-mentioned RAM are supported by such frequencies:

  • DDR4 - from 1600 MHz to 3200 MHz (most popular - at 2133 and 2400 MHz).
  • DDR3 - from 800 MHz to 2133 MHz (most popular - by 1600 MHz).
  • DDR2 - from 400 MHz to 1066 MHz (most popular - 800 MHz).


Delays in accessing RAM or timings are considered in frequency tacks. This is another parameter that affects the choice of RAM for your laptop.


The choice of RAM for a laptop is not as easy as it could seem. It is important to choose a new bar correctly, without missing the characteristics that really affect the work and speed of the computer. Nevertheless, following this principle and armed with knowledge from this material, you can choose the optimal memory module for your favorite device.

A modern laptop is quite capable of replacing a stationary computer. The pros is obvious, but the mobility has a reverse side - the limited capabilities of the upgrade: the processor and the video chip will not always change. But it is possible to increase the amount of RAM without any problems, and in many cases it will be enough to inhale the second life or reveal the potential of the actual iron acquired on the principle of "and I will add then". We tell what to do when this is the "sweat" finally comes.

How much do you hang in gigabytes?

The speed of reading / writing data from the RAM is many times higher than from the hard disk and even SSD. But when the "RAM" volume is not enough, the system has to record data on the hard disk in the paging file. Naturally, this leads to a tangible loss of performance. To understand what amount of memory is to navigate, briefly imagine various configurations and tasks that they are able to solve.

1 GB - blatant archaism whose place is in the dump of history! Actual OS with such a volume is not working trite. And the "dozen", and "Seed", of course, are loaded - but it will be difficult for work. In nature, this amount of memory is almost not found: except in cheap terminals and museums of computer history.

2 GB is an absolute minimum To print in Word or to start a browser with a pair of open tabs. Windows 10 "will devour" by almost 70% of this volume, which together with a slow paging file will make the work extremely uncomfortable. Among the new devices, you can find such a modest configuration, perhaps in Compute Stick, in the most inexpensive laptops, and in Windows tablets from the Middle Kingdom.

How to choose a memory to speed up the laptop

4 GB - Basic Regulator of Office Worker . It is not worth waiting for the wonders of performance, but the system will not be regularly thinking about the eternal. Taking into account the appetites of the Windows itself, the free 2.5 GB of RAM will remain free, they should be enough for web surfing, office applications or viewing HD video. Moreover, it is better to run these tasks alternately to avoid the "brakes". Also consider that 4 gigabytes are a ceiling in which 32-bit operating systems are resting, they are simply not able to use. If you decide to make an upgrade, you will need to replace the OS on the 64-bit version.

How to choose a memory to speed up the laptop

8 GB - standard volume for comfortable work . It is such a digit that will allow, without thinking, press Alt + Tab directly from any not too heavy game in the YouTube window with a guide for its passage. And do not observe the slideshow in full screen mode. Tables for hundreds of rows and formulas will cease to be brazed, and the number of open tabs in Chrome will remind themselm much less often.

A little refinement: lovers to open a few dozen tabs of eight gigabytes are still small. On the test machine (Intel Core i5-3570 / 8 GB DDR3-1600, Windows 10 Pro) When you open 40+ tabs, the memory is filled with 80% and the executable chrome.exe file simply "departed". On two other computers with eight gigabytes of memory and Windows 10, the experiment led to similar results.

How to choose a memory to speed up the laptopThe system, antivirus and 49 chrome processes occupied 82% of RAM. After a second browser "crashes" from memory

To solve such a problem, you can land the browser on the "diet" by setting the extension to unload tabs from memory. But it is better to increase the volume to 16 GB - this is enough even for several serious tasks launched simultaneously.

How to choose the right module: type, frequency and compatibility

Step 1. Find out the type of memory. Before drinking useful gigabytes, you need to clarify how many slots to install the memory planks are in the laptop and how many of them are already busy. And at the same time - what type of memory is needed for this model. You can use the search engine and documentation, but it is easier to install the AIDA 64 EXTREME program. It needs to select the "System Board" tab, and then the SPD string from it you will receive complete information about the number and type of available modules. All supported frequencies and the highest possible to install the volume will tell the "Chipset" tab.

How to choose a memory to speed up the laptop

Do not forget that one of the two modules can be sprinkled directly on the system board, and a single physical slot will be available for upgrade. In this case, the optimal choice will be the bar, identical according to the characteristics of the already existing.

Step 2. Check compatibility with the processor. The motherboard is not the only component of the laptop that imposes requirements for the characteristics of RAM, its restrictions imposes a processor. So, it will not be superfluous to clarify and its specification. Make it easy: Go to the official website of Intel or AMD, we find your processor model in the list and process the MEMORY SPECIFICATION string. It will not hurt and view the list of recommended options on the website of the manufacturer of the laptop. In the end, you can use the ready-made solution - select the model of your device and see the recommended characteristics of RAM modules.

How to choose a memory to speed up the laptop

Step 3. Specify the frequency of memory. Is the frequency of memory for a laptop important? On the one hand, the data processing speed due to high frequency is really increasing - for example, when processing video files or archiving. The numbers are also on the FPS cherished meter in games. But do not count on serious acceleration of the laptop due to high frequencies. Memory does not work by itself: much depends on the processor and the capabilities of the motherboard. For example, the newest Core i7-8650U supports operation with a frequency modules up to 2400 MHz. And the benefit from the installation of "high-frequency" planks in a laptop based on it will not exceed the placebo effect.

The correct choice will be the memory with the maximum frequency recommended for your processor.

How to choose a memory to speed up the laptop

Owners of laptops with RAM of the penultimate generation should be paid attention to the differences between DDR3 from DDR3L: due to the difference in power consumption, these standards may be incompatible, despite the external similarity and the same connection connector.

The optimal solution will be two modules identical according to the characteristics. It is necessary for memory operation in two-channel mode, which is able to actually increase the system performance.

Two planks are better than one: justification in numbers

The difference in performance between one- and two-channel mode of operation is particularly obvious on the example of processors with built-in graphics. The increase will be about 10% in games and most everyday tasks. And in separate scenarios (for example, when video editing), you can get acceleration by 20% or more - especially when calculating complex projects that require the maximum bandwidth of all "iron" components.

For example, compare the 3D MARK benchmarks running on Lenovo ThinkPad T470 laptop. The first screenshot shows the result with a single line of 8 GB. On the second - with two modules of 4 GB. The total amount of memory remained unchanged, but the overall assessment increased by 16% through the use of a two-channel mode.

8_2.On the left - the test results with one 4 GB memory bar, right - with two 4 GB placters. Groost amounted to 16 percent

Such an impact can be explained by the fact that the video lane built into the processor does not have its own memory and use systemic. For the same reason, you should not put RAM with a frequency lower than in the specification of your processor. Graphic performance will fall significantly. An exception will be except that the Intel Core database with the AMD VEGA video frame (with HMB2's own memory) or Intel Iris Pro (with a dedicated SDRAM cache).

Rules safe installation RAM

So, the theory and campaign at the store behind - it's time to start upgrade. Starting with an obvious - laptop must be turned off and disconnect from the power supply. The simple, it would seem that the rule: however, the folk craftsmen, breathing their device in attempts to produce a "hot replacement", are found in the practice of service centers to this day. For the same reason you need to disconnect the battery. In most cases, this procedure will not cause this procedure, but if a model came across, the battery of which is located inside the case and is connected to the motherboard with the help of a connector, without complete opening it is not necessary. The desired power cable must be carefully disconnected and traced so that it does not touch other components. Or, nevertheless, seek help in the service center. The same applies to the few models whose battery is supplied to the fee. It's easier to sign in your own bad luck and entrust work by a specialist: repair of the power chain is expensive.

How to choose a memory to speed up the laptop

But, even disconnecting the battery, it is not worth a hurry. First you need to reset the residual voltage: To do this, climb the switch on the laptop for 15-20 seconds. And only now it's time to pay attention to the slots of RAM in the form of special connectors with side latches. Depending on the model, you will need to remove the small lid on the bottom of the housing or the entire bottom cover. Having found a slot with the installed bar, pull out the side snaps to the sides and carefully remove the module from the connector. It is categorically not recommended to touch the gold-plated contacts at the base! At best, you can get BSOD due to conduction disorders, in the worst - the refusal of one (or even several) "iron" components.

If you install the RAM module in the laptop, which is incorrectly selected, the operation of the entire system can be disturbed. In order to correctly choose a RAM model, it is necessary to take into account the characteristics of not only the motherboard, but also the processor, as well as the already installed RAM module. In this article we will help you to figure out how to choose the RAM for laptop, and will also answer the question of how to find out the model of the installed RAM.

How to choose the right memory for a laptop

How to find out the RAM on the laptop

If you build a system upgrade and want to increase the amount of RAM, then first of all you need to know which RAM model is already installed.

Unfortunately, it is not possible to get information about the RAM model using the Windows operating system services, the maximum that can be learned is the volume of RAM. Therefore, to solve this issue, do not do without installing the utility for the diagnosis of the system.

In our example, we will use the popular program for diagnosing AIDA64, but you can use any other similar utility.

Instructions, how to find out the RAM on the laptop using the AIDA64 utility:

  1. Download and install the program;
  2. After starting the utility, select the category "System Board"; System fee section
  3. Then click on the icon, which is called SPD. SPD.

If everything is done correctly, the window will be updated, and you will see detailed information about your RAM. Pay attention to the following characteristics:

  • name, size and type of module;
  • memory type;
  • Memory speed;
  • module width;
  • Module voltage.

Detailed RAM Information

The listed characteristics are important to consider when buying an additional memory module.

How to choose RAM for laptop

It has already been said above that when a module is selected, the characteristics of the motherboard, processor and the already installed RAM module must be taken into account. Therefore, the first thing to determine which motherboard and the processor stand on your laptop. Here you can read how to determine the model of the system board.

Type of module

If you choose the RAM for the laptop, the type of module must be SO-DIMM. Everything without exception, laptops have on board the RAM of this standard.

Memory type

Go to the official website of the manufacturer of your motherboard and read the information that the type of memory is suitable in your case.

In addition, if the RAM module is already installed, then focusing on it, choose an additional RAM.

Permissible memory

Before selecting RAM for laptop, find out what maximum memory is supported by the motherboard. It is extremely recommended to exceed this value.

It should be borne in mind that RAM of more than 4 GB will be properly functioning only on a 64-bit operating system. For a 32-bit system, in this case, it is necessary to produce special settings.

If you address the topic about the volume of recommended memory, depending on the purpose of the laptop, 2 GB is quite enough for office laptops, and no less than 4 GB should be installed for gaming.

Memory speed or clock frequency

The main condition in determining the suitable clock frequency of RAM - it should not be higher than the clock frequency of the motherboard. The second condition - if an additional memory module is installed, it is recommended that all modules have the same clock frequency.


An ideal option is considered when the total bandwidth of all installed RAM modules coincides with the microprocessor bandwidth.

Memory timings

Here errors with compatibility should not occur, but should be taken into account, the smaller the timing indicators, the better.

Manufacturer of RAM

When installing an additional module of RAM, it is recommended that all modules are one firm.

12 400.

Hi, GT! A detrimental tendency to make laptops is all thinner and thinned already deprived us of upgrades and placer ports. At best, the manufacturer gives to replace the drive, at worst, it offers to buy an ugly and indecently expensive docking station with additional connectors.

Fortunately, professional and gaming laptops still remain true to the old concept.


Computer in which you are free to upgrade iron. About Upgrade Memory Subsystems today and let's talk.

Frequency potential and memory with non-standard characteristics

The old woman DDR3 is still actively attended on the market - even the "flagship" MacBooks still use it, and not a new standard: good, the Intel Core processors of Skylake and Kaby Lake generations can work with both types of memory, however, with some limitations. Since the memory controller in the CPU is one, and the voltages 1.2-1.35 volts are normal for the "new" memory, then DDR3 must be with the asscription L (Low Voltage) at the end and reduced to 1.35 operating voltage. However, in our time on mobile platforms, only such memory is present, and modern production technologies allow you to make memory working both on a voltage of 1.35 volts and 1.5, and any mobile DDR3 from Kingston will suit both a laptop and a compact system with " desktop "processor.

According to specifications, the last two generations of I3 / I5 / I7 processors in laptops are supported by DDR4-2400 MHz, DDR3L-2133 MHz and DDR3L-1600 MHz: At first glance, the choice is not great. However, the same limitations formally exist on desktop processors and successfully cost through the BIOS motherboard. In confirmation of the above, it is possible to give examples of laptops with the Modules of DDR4-2800 MHz installed from the plant and the same MacBooks with their 2133 MHz DDR3L.

Overclocking on a laptop

Since Intel's greedy managers blocked the possibility of overclocking for ordinary mortals, demanding additional payments for "Now-non-such-and-free" megahertz, overclocking RAM on laptops is available in two cases: you have a flagship model and processor with HK index (I7 -7820hk, i7-6820hk) or on thematic forums there are modified (or "drunk" from the manufacturer) BIOS for your model with a unlocked advanced settings tab.

To ensure comfortable conditions in the MONSTROUND ASUS ROG GX800V, a hybrid cooling system is used + external dock with "water"


Asus, MSI and Lenovo still last generation transferred their flagship gaming laptops on the advanced standard of memory, but who said that a laptop with a conditional i7-4960hq is time to retire? Yes, a video card for three years ago in modern games I work so-so, and


Video card - and worse, because the performance of graphics in the "big brother" and the mobile PC was equal only in this generation, but can you play on the "medium"? And the conditioned photoshop, illustrators and other three-de-macams at all do not care about fashion technologies: OpenGL is supported, 1-2 GB of video memory is - and good. And the rest and in the fast RAM can be put if that.

Compatibility table

To simplify the upgrade of old systems, we accounted for a small plate that will help you not make a mistake with the choice of RAM for your iron friend.

If your laptop works on the graph built into the processor and costs the "slow" factory memory - under the upgrade it is worth replacing the old module for a pair of as fast as possible, praise compatible with your system.

IGPU does not have its own memory stocks (except for a modest cache and personnel buffer), and operates the system RAM to store models, textures and intermediate computing results, and a slow memory subsystem - a bottle of neck for relatively powerful options intelHD (530 and higher, and, Of course, a good graphics of the IRIS and IrisPro class). Details of accelerating the operation of the video recorder of the video recorder of the RAM can

read in our previous article



With the memory of DDR4, everything is somewhat simpler: only two generations of mobile systems are supported, based on Intel Core 5000 and 6000 episodes, and in gaming laptops (as well as some monoblocks and ultra-compact PCs) usually from the factory costs a sufficient number of RAM. Of both generations there are exceptions - the flagship i7 "mobile" series with overclocking support - their memory controller provides the operation of high-speed modules and supports overclocking.

Unfortunately, the wide support of high-speed SO-DIMM DDR4 with a frequency of 2800 MHz Intel has implemented only in one processor on the market (and he lives in indecently expensive systems), and AMD has not yet shown Mobile Ryzen: Kingston just did not do unpopular direction, and in laptops with i7-7820hk extremely rare


Set the maximum volume (64 GB) out of the box.

Flour selection and pitfalls

For most active users GT Upgrade is unlikely to be an abnormal situation, and a clear understanding of the necessary memory volumes is complemented by a good knowledge of the iron part, only Geektimes became so popular that the articles from it regularly disagree on social networks and shamelessly proceed to other resources even without reference to the original source Therefore, we can't leave some obvious moments.

How to find out the current amount of memory and its characteristics?

The easiest way to live users of Windows 10. Open the task manager (SHIFT + CTRL + ESC), in it, the "Performance" tab and go to the memory section:

Where to see a specific processor model?

Everything is there, but in the "Central Processor" section:

What if I have Windows 8 / Windows 7?

You can use the free utility.


- It will show comprehensive information and about the processor, and about the set of installed memory modules.

What can be pitched stones?

In most cases, no, however, some laptops with junior Intel processors refuse to perceive 16-gig DDR3L memory modules, the maximum volume is limited to 8 GB per slot, so that the only available option is 2 plates of 8 GB. As we are talking about


Processors (I3, Pentium, Celeron) and their "energy-saving" versions - it is unlikely that there is a task that will supply a laptop with such a filling in an uncomfortable memory position (at maximum 16 GB), and not by computing power.

The system says that I have 2 more memory connections, I opened a laptop - and the only available slots are busy, what to do?

There are not many options: either the manufacturer decided to save a couple of bucks and did not react two additional connections, and the BIOS one on the entire line of laptops, or they are on the other side of the motherboard.

In the first case, the space for RAM slots can be detected next to the available two - in some service may well have a missing elements, but it's worth ten times to study the question, see the adjacent models and shist the forums: may not only be installed not only contact sites , but also their strapping.

Unusual location of the RAM slots on the Lenovo ThinkPad laptop.

In the second, see the guides on the disassembly of your laptop on the network - either under the keyboard, the hatcher will be detected with access to two connectors, or have to remove the motherboard itself.

And what is the compatibility of the already installed memory with the new one?

If you bought a module with the same frequencies as already existing - there will be no problems. Runs for laptops extremely rarely has non-standard timings, and the stitched JEDEC profiles have specific delays values ​​for each operating frequency. Only two processors (those are 6820 and 7820hk) can work with "overclocking" memory, and in laptops with such iron usually costs 32 or 64 GB - it is unlikely that you will need an upgrade in the near future.

All this is too difficult, I will not remember

Well, in this case, the KVR16LS11 / 8 is suitable from DDR3 with an extremely high fraction of probability, and for Ponnee systems, with DDR4 on board - KVR21S15D8 / 16. For complete confidence you can use

By the way, you probably heard that the memory of Kingston is a lifetime warranty. Why this is how it is generally developed by the history of our company's memory you can look at the roller below.

If your laptop began to work slower and badly pull modern programs and games, then it can be slightly "pumping". However, for laptops, the methods of "pumping" are limited. In most cases, it is possible to replace only a constant memory (hard disk) and operational. Consider how to choose the RAM for laptop to get the maximum result without overpayments.

There are a number of criteria for which you need to look when buying planks. We list the most important of them.

The possibility of upgrades

To begin with, you should learn whether it is possible to increase the RAM on a laptop in principle. This is not a celebrating question: there are models with an unintended body, as well as such where the memory is initially soldered into the motherboard and has a fixed volume. As a rule, it is ultrabooks in which the capacity is sacrificed to compactness and design.

You can find out in the official description of the model, as well as reviews on specialized sites.

A type

This is the first point to watch. If the RAM bar is not compatible with your motherboard, it is impossible to use it. For 2018, the following types are relevant:

  • DDR3 - continues to be actively used.
  • DDR4 - is a new format and better focus on it when choosing a laptop.

Laptop motherboards usually support some one of these types, unlike desktop models in which there may be slots of different standards. Therefore, specify which type of type is supported by your laptop, and buy the bar exactly this standard.


Simply put, physical standard of memory module. It must be compatible with modern laptops. Almost all models for 2018 support the SO-DIMM standard created specifically for portable compact models. In size, such modules are less than those designed for desktop computers. In short, take SO-DIMM - Will not be mistaken.

Forms Factor RAM


From the point of view of a simple user, this is the main characteristic. We do not argue: 8 GB is better than 4 GB, and 16 - better than 8. There is no extra gigabyte here.

However, before you take the most outstanding modules that are available on sale, ask your laptop motherboard specifications. And specifically, the maximum supported volume. If he rests on the ceiling of 8 GB, it makes no sense to take the planks on 16.

Another important parameter is the number of memory slots. It may vary:

  • One slot with a replaceable bar
  • Two slots with replaceable straps
  • Spit memory plus slot

In all these cases, strive in the upgrade to achieve a maximum, but not go beyond its framework. Even if you are limited to office work with not the most voracious programs, remember: a lot of memory does not happen!

Recall how to find out how much RAM on the laptop. If you use Windows 10, then right-click or touchpad on the Start menu and select the System string. The window that opens will show the main parameters of your computer, including the volume of RAM. In older versions, the System section can be found in the control panel.

Number of memory

Another important factor: two planks in parallel mode work better than one of the same volume. Therefore, if your laptop supports up to 16 GB of RAM and is equipped with two slots, it is more expedient to buy two modules of 8 GB than one to 16 GB. Of course, with one free slot of this choice you do not have.

Operating frequency

It would seem that the higher the frequency and the faster the memory works, the better. However, you should not blindly chase at frequencies and assume that 3200 MHz is always better than 2400.

In fact, working frequencies are limited to the motherboard. If it does not support frequencies above, for example, 2666 MHz, then the purchase of faster memory is irrational. To the regular 3200 MHz dispersed it will not be able if the supported motherboard frequencies are less.

We add that for office work you can safely buy modules with a minimum frequency. At the work of Office or browsers it will not affect. But to work with video, audio, graphics or games, it makes sense to take the most "pinchula" memory.


Under this word, intervals between individual operations are hidden. It would seem that they are less, the "more promptly" will be a memory (sorry for the pun). And there is. First of all, it is necessary to watch the Latency parameter (in Russian it is called "latency" or "delay").

Oddly enough, more modern DDR4 latency is higher than that of old good DDR3: 15-16 milliseconds against 9-11. It batches its other advantages.

As in the case of a frequency, it makes sense to chase the maximum supported values ​​only if you are engaged in its laptop resource-intensive work.


Once in fashion were "Holivari" on the topic of what manufacturer the rapid memory is more reliable. Time passed everything in places. Today, almost any famous vendor can provide a guarantee for their modules, and they honestly work out due time and even more. The probability of marriage is extremely small, and warranty exchange most often works.

Therefore, you should choose not so much on the recommendations as by the presence of an official service center that works under warranty in your city.

It should be noted that the modules of well-known manufacturers (Samsung, Kingston, Transcend) are forged more often than Corsair, Goodram and other brands, which are mostly among enthusiasts. Therefore, it is necessary to buy in proven stores that give a guarantee also for their part.

It is the main thing that you need to know before selecting the RAM for a laptop. The rest is the question of your taste and budget.

Types of RAM

There are certain types of RAM intended for use in various devices. Types are incompatible, so they will never be interchangeable. But what's the difference between them? There are many differences, including constructive.

How to select RAM for Computer and Laptop: Important Parameters and Best RAM manufacturers

Let's see what the variable memory of individual types is distinguished:

  • SO-DIMM. . Compact modules used in laptops and monoblocks. They differ in reduced dimensions and a bit different design. In this case, such a RAM can absolutely not differ from full-size in terms of performance. This is a compatible RAM, which is also used in monoblocks. But in the classic PC it is not to put it. After all, it is completely different.
  • Dimm. . Classic modules used in PCs. It may comply with DDR2, DDR3 or DDR4 standards. Different with an extended fee. The location of chips can be different: both with one and on the other side of the board. Many top models are equipped with aluminum radiators for cooling, which is very useful when overclocking the RAM. This format is suitable for all modern processors.
  • ECC. . Server memory used where not only speed is important, but also stability. The design is similar to DIMM. But it will not work in the usual computer. Requires a specific motherboard. Designed for use with Intel Xeon processors. It is sharpened to work with buffers. Even if she could function in a home PC, it would be a sense of it, it would not be especially much: it is designed for multithreading.

Now let's talk about DIMM memory types. After all, even this species has certain models that are distinguished by constructive features. Select the RAM without deciding with its type, it is impossible.

  • DDR. . Outdated format. Planks of this type are no longer produced. They were used on old machines. The frequency indicator did not exceed 500 MHz. RAM could only work with old processors (like AMD Sempron of the first generation).
  • DDR2. . Modules of this format are still found on sale. They will use those who want to revive their old computer. As a rule, the maximum volume of such slats does not exceed 4 GB. About how to choose DDR2 RAM2 for a computer, we will talk later.
  • DDR3 . One of the current standards. Differs in high performance. The module may have a volume of 8 GB. Also, the memory of such a standard is often found in laptops and budget PCs. Able to work in two-channel mode.
  • DDR4. . Modern standard. Used in top gaming machines and professional stations. Suitable only to the motherboard with appropriate slots. Maybe without problems working in a pair with top processors.

It is worth noting that different generations of the DDR standard are incompatible. They are designed to install in separate slots. Special excavation (key) is in different places. But even if it could be placed in the connector, electrically they are still not compatible with motherboards intended for another standard.

What is the frequency of the memory module

RAM frequency affects its speed. The higher this indicator, the faster the RAM processes the commands. The memory module with a certain frequency should be selected depending on the capabilities of the processor and the motherboard. Pick up the processor the RAM is not so difficult. In the characteristics of any CPU there is information about which frequency is supported.

Choose RSEZ RMZEN difficult memory. This platform is demanding of RAM. The higher the frequency, the more productory the whole platform will turn out. It is known that for normal operation, the CPU AMD Ryzen requires modules with a frequency of at least 3200 MHz.

But such planks are expensive. There is one lifehak. Even the cheapest 2666 MHz memory can accelerate to 3200 automatically. Moreover, this can be the platform itself without user participation.

If you need to find out what kind of rates to select for Ryzen, just look at the processor specifications. Then find the RAM 2666 MHz and take a look if it can accelerate up to 3200 MHz. If so, it is possible to acquire such modules. With them, the CPU will work normally.

There is another feature. Ryzen works poorly with modules based on Hynix chips. Why so - it is not clear. If you want to buy a fully compatible RAM, you can look at the official AMD website list of recommended memory modules.

Under the processor from Intel, you need to choose modules with frequencies that it supports. It will not save here. If, for example, Core i7 is able to work with a RAM of a frequency of 2666 MHz, then such memory and must be purchased. Overclocking RAM in this case does not work as AMD.

What frequency of RAM to choose

The frequency should be no lower than that specified in the processor specifications. Only this can be achieved good performance. But notice, the frequency that is indicated on memory modules is significantly different from the real one. Therefore, some users turn out to be confused. Now about what frequency of RAM to choose.

In principle, modern CPUs are able to work with any frequency modules (except Ryzen). But it is not recommended to acquire strips with values ​​of less than 1600 MHz. They will be too slow. It is better to look for RAM with a frequency of at least 2666 MHz. If we are talking about DDR4 standard. Such an RAM will be more acceptable.

Before you choose the RAM to the motherboard, you need to look at the characteristics of the motherboard, which maximum frequency it supports and make the appropriate conclusions. Modern boards are able to work with almost any frequencies. But modules with values ​​of less than 1333 MHz may not start. It is worth being neat in this regard.

How to choose the optimal volume of RAM

It all depends on what purpose the car is going to. After all, one thing is home PC for multimedia, and a completely different game computer or professional station. To begin with, we will tell you what volumes are. Separate planks may have values ​​from 2 to 16 GB.

Now what amount will require for certain scenarios:

  • 4 GB . Minimum mandatory volume for today. This will be enough to surf on the Internet, watching movies in Full HD listening to music, as well as to work in Word. These are the tasks that are performed on the usual home PC. To do something more interesting (for example, to work in Photoshop) on the machine with such a volume of RAM will not work.
  • 8 GB . Such a number of RAM is suitable for work in editors. You can also view video in 4K without brakes and freezes. For many games there will be enough this size. But only for those that were released until 2018. Fresh titles may not start. PC with such memory is suitable for various tasks.
  • 16 GB . The optimal volume is today. It is enough for fresh high-end toys. There will be no questions about working with graphic editors. In some cases, you can even create a simple animation. To compile the code of this size of RAM is also quite enough.
  • 32 GB . It is so much RAM is found in professional machines for work. With such an indicator, you can easily mount the video, engage in 3D modeling, rendering and so on. All these processes will occupy significantly less than if they were performed on a PC with 8 GB RAM.

Which latency of the RAM is better

The latency is the number of delay cycles during the transition from the moment the address is specified to the process of obtaining data. In other words, this delay before performing the operation. Understand which latency of RAM is better, it is possible only on a specific example, since the explanation will be oversaturated by technical terms.

For example, if in the specifications of the module DDR2 2400 MHz it is indicated that RAM has latency of CL16, then the calculation of the real delay must be made by the formula, multiplying 17 to 0.83. Last value is a DDR2 type synchropulse period with a specified frequency. As a result, it turns out that the delay is equal to 13 milliseconds.

And if the latency value is lower, then the RAM will spend less time on command processing. Accordingly, to choose CL15 or CL16 values ​​does not make sense. It is clear that the first version of the performance will be higher. Therefore, remember: the smaller the CAS Latency indicator, the more productive will be the RAM.


These are delays, before performing certain operations. Timins are calculated in the amounts of clocks that pass before the execution of the command. Simplified: than this value less, the faster the memory will work. For each DDR standard, there is a set of timings that take into account the features of the RAM design.

For DDR4 Standard value 15-15-15-36. Reducing these numbers with the same RAM voltage can significantly increase the operating frequency and overall speed. But there is a certain limit. It is necessary to deal with the features of each type of memory in order to carry out similar overclocking. Selection of timings need to be accurately.

Other selection characteristics

We have already spoken about how to choose the right memory correctly, but they listed only the main features to pay attention to. However, there are still characteristics that allow you to select modules based on user requirements.

How to select RAM for Computer and Laptop: Important Parameters and Best RAM manufacturers

They are not as important as timings, frequency or latency, but they need to mention them:

  • Two-channel mode . It depends on how many planks can be installed in the PC. Even if there are only two slots there, then this mode can be activated. Its essence lies in the fact that two similar modules, working in this mode, provide the highest performance. But the planks should have the same volume, similar frequency, etc. It is desirable that these are modules from one company.
  • Energy efficient memory . This type of RAM has in its title Literon L (for example, DDR3L). Its feature is that it consumes less energy to work. Such modules can be useful in laptops. After all, they will positively affect the overall autonomy of the device. The maximum performance plan in this case decreases. After all, RAM cannot be energy efficient and powerful at the same time.
  • Brands . In this industry, there are best manufacturers that produce reliable and productive RAM. These are companies such as Samsung, Kingston, Hyperx, Corsair, G.skill and Patriot. They produce both elemental level models and powerful options intended for gamers.

Recommendations for the selection of RAM for the game computer

All of the above features (like latency or frequency) are also important for the gaming computer. But there are specific parameters that are characteristic exclusively for this segment.

Now about them Read more:

  • The possibility of overclocking . This parameter determines how to increase the performance of RAM. As a rule, modules for gamers are able to accelerate to unprecedented frequencies. If you collect a powerful car, pay attention to this feature of the RAM.
  • Radiator . Powerful RAM strips are often equipped with aluminum radiators. With a regular use of them, there is no sense. But if you plan an impressive memory acceleration, they will help cool the modules. Especially with raising voltages.
  • Backlight . Affects the aesthetic side of the assembly. Useful if the computer components are located in a transparent case. On energy consumption, such LEDs almost do not affect, but the memory looks beautiful.


Selecting RAM for Computer - Complex Procedure. You can not take the first module. We will have to take into account several characteristics. Moreover, the same memory range is not a guarantee that it will earn in two-channel mode.

At the beginning of the review, we made a comparison of three memory modules. We will remind them of their parameters:

• Samsung DDR4 2666 DIMM 8GB for Computer . A 8 gigabyte module that can be accelerated and able to work with modern processors. Suitable for the game PC and has a regular frequency of 2666 MHz.
• Kingston KVR1333D3S9 / 8G . Runs for a laptop with 1333 MHz. 16 chips are located on both sides of the board. The volume of the bar is 8 GB. If you replace this module old memory, then the performance increase will be essential.
• Kingston KVR800D2N6 / 2G . A 2 GB module for an old computer that matches the DDR2 standard. It can work at a frequency of 800 MHz, but quietly accelerates to 1000. With it, the old car will find a new life.

Before selecting RAM for a computer, read the characteristics of your processor and motherboard. After all, without it, you can acquire what is not suitable for a specific PC.
