Everyone wants their computer or laptop to fly without freezing or slowing down. A budget option achieving this goal is system optimization. This is not always effective. A practical way to achieve speed is to buy bars random access memory(RAM).

There are many types of RAM. This makes it difficult to choose. In this article I will tell you how to choose and buy the right RAM sticks for your computer or laptop.

The criteria for choosing RAM for a laptop differ from the criteria for desktop computer only physical size. In a laptop, the RAM modules are smaller and shorter. So in general the selection method is the same.

By the way, in modern system units there may also be operational modules, the same as usually found in laptops. This is done to save space.

If you are deciding which RAM sticks to buy, then the most reasonable and the right way will refer to the website of the developer of your motherboard. It is there that there will be a detailed and truthful list of all recommended RAM modules that will suit you. But everything there will most likely not be in Russian, and still, not all points will be clear. Therefore, let’s look at the parameters by which RAM models differ.

RAM interface

RAM differs in its interfaces - the number of contacts and the location of the groove and cutout. There are several types of RAM interfaces. The website of the motherboard developer, the markings on the old RAM (if any, if you decide to upgrade your computer), or special software will tell you which RAM sticks you should buy.

DDR, DDR2, DDR3 are types of RAM interfaces. There are several more less common ones. They are all physically different from each other, so if you buy the wrong RAM, you will not be able to insert it into your motherboard. There are also electrical differences, so don’t even try to fit them in.

Perhaps this is the most main parameter, which you should find out before buying RAM sticks.

RAM form factor

This is exactly what distinguishes the RAM of a desktop computer from portable laptop. And after seeing your RAM once, you will know exactly what format factor it is.

There are two types - DIMM and SO-DIMM. SO-DIMM is shorter, respectively, for laptops. DIMM – for system units.

RAM frequency

Frequency must be maintained motherboard and the processor (again, the best option To find out, look at the manufacturer’s website or on the labeling of the old RAM). The frequency is indicated after the interface. For example, DDR3-1333, where 1,333 is the frequency in megahertz.

The frequency of RAM determines the data transfer rate, that is, its performance. But this will not make the computer work much faster. Select RAM from correct frequency necessary. Don't chase for more high frequency, If motherboard and the processor does not support it.

If you connect RAM with a lower frequency to a motherboard that supports a higher frequency, then the motherboard will work without fully using its resource. If you connect RAM with a higher frequency to a motherboard that supports a low frequency, then the RAM will not show its full resource. In addition, in both cases there is a high probability of occurrence various errors in RAM operation.

Therefore, it is extremely important to determine the frequency at which your motherboard and processor can operate and buy RAM sticks according to it.

Remember that if you have multiple RAM modules in your computer and they are at different frequencies, both modules will operate at the lowest frequency.

RAM capacity

These are volumes that increase computer performance. The bigger, the better. The times when RAM was measured in megabytes are long gone, and so they are now measured in gigabytes.

The amount of RAM is also indicated on the case in the marking, usually in front of the 4GB DDR3 interface - that means 4 gigabytes of brains.


RAM timing

Timing is another murky thing that you will encounter when choosing RAM. And I won’t dwell on it too much, so I’ll just say three things.

First, the lower the timing, the better, the faster it will work.

Secondly, all RAM in the computer must have the same timing.

Third, the timing on the RAM case is marked CL. For example, CL 9-9-9-24.

- This is one of the main characteristics of any computer. This determines how many programs the user can run simultaneously without significant losses in performance. The performance of the computer is also affected by the speed of the memory itself.

Therefore, selecting RAM for a computer is a very important moment. In this article we will talk about how to find out what RAM your motherboard and processor support.

In order to find out what RAM the motherboard supports, you need to go to the official website of the manufacturer of this board, find there the desired model and see its characteristics. If you don’t know, you can get this information using any program for viewing computer characteristics. For example, you can use free program CPU-Z.

Launch CPU-Z on your computer and go to the Mainboard tab. Here at the very top the motherboard manufacturer (Manufacturer) and its model will be indicated.

We take this data (motherboard manufacturer and model) and enter it into any search engine. After this, you need to study the search engine results and go to the manufacturer’s official website. Most likely, the link to the official website will be at the very top of the search results.

After going to the manufacturer's official website, you will see information about your motherboard. Here you need to go to the page with detailed characteristics and find there information about what RAM this particular motherboard supports.

Also here you need to look at the maximum amount of RAM the motherboard supports.

After that, enter the name of the processor into the search engine and go to the manufacturer’s official website.

There we also look at the maximum amount of RAM that is supported by your processor.

Conclusions and tips for selecting RAM for your computer:

  • In order for RAM to work, it must be supported by both the motherboard and the processor. You can get information about maximum frequencies on the official website of the motherboard and processor manufacturer.
  • The amount of RAM should not exceed the maximum amount specified in the specifications of the motherboard and processor.
  • The best option is RAM with the maximum frequency supported by both the motherboard and processor. However, you are not required to use the most fast memory of those that are supported. If you want to save money, you can choose RAM with more low frequencies, and everything will work.
  • If you install RAM the right type(DDR1, DDR2, etc.), but with higher frequencies, then it will still work, but at maximum frequency, which will be supported by the motherboard and processor.
  • If you install memory modules with different frequencies, then they will operate at the maximum frequency of the slowest module. But it is better to avoid such a situation.
  • If you want to increase the amount of RAM, it is advisable to choose memory modules with exactly the same characteristics as those of the modules that are already installed.

I processed information almost instantly, especially when using applications, including gaming ones. Great importance has Random Access Memory (RAM, RAM), which sets the speed of your device. We will give some recommendations on how to choose RAM for a computer or laptop.

The choice of RAM for a PC is influenced by reading speed and interaction with other components of the PC.

The choice of RAM is important, it gives a start to the “overclocking” of a computer or laptop; correctly selected RAM will later help to avoid additional injections of funds. This memory is connected to the motherboard, so you need to select it based on the available components. If you buy a cool RAM, but it turns out your motherboard doesn’t support it, you’ll have to put it aside until better times.

How do you know what RAM your motherboard supports? Go through a few steps:

  • find out the markings using DirectX: by pressing the Win+R combination, enter dxdiag in the line, remember/write down the displayed information about the manufacturer, the name of the PC model;
  • go to the manufacturer’s website, for example, Gigabyte;
  • Use the marking to find the motherboard model of your computer/laptop; to make it quicker, you can enter the data into the search bar;
  • go to “Supported processors”, “List of recommended memory modules”, save the list;
  • find the line with your processor type, memory model.

This way you will make sure that the motherboard and processor will not conflict with the memory you have chosen; the combination of these three components will allow you to increase PC performance, avoiding “ blue monitors of death".

Determination of technical parameters

RAM type

DDR 3rd generation is popular on the market, also DDR3, which has increased clock speeds, reduced energy consumption, and therefore low heat generation. At the same time, DDR2 is also being implemented, and even the outdated, very expensive DDR1 is found. The types differ in structure and are incompatible in one device. If you make a mistake, buy the wrong plank, you simply won’t be able to insert it. Is there some more newest type DDR4 memory, has increased frequency characteristics, undervoltage. Frequencies supported are 2133–4266 MHz.

Form factor

The form factor is undoubtedly useful to take into account if you are planning to buy RAM; this criterion does not affect the performance of the work, but determines the dimensions of the device and the type of design of the memory strip.

DIMM, SO-DIMM

DIMM means that the contacts are arranged on both sides. DIMM is used for a regular desktop computer, and SO-DIMM is used for a laptop, built into monoblocks, and sometimes in multimedia compact PCs. These strips differ in size, SO-DIMM is half the size.

Frequency, baud rate

Frequency along with data transfer rate are the main characteristics of RAM. To determine how to choose RAM for a computer or laptop, look at these characteristics. Frequency determines how much data can be transmitted per unit of time. This information is recorded in the module characteristics. For example, the module is marked DDR3 1333 (PC-10600), which means memory with a bus of 1333 MHz can pass 10600 MB/sec. Frequency has a different designation:

  • “DDR2(3)-xxxx”, where xxxx is the effective frequency;
  • or “PC2(3)-yyyy”, where yyyy is peak throughput.

Which frequency is right for you?

If you are thinking about how to choose RAM for a laptop or computer, when deciding on the frequency indicator, calculate it based on the capabilities of your system. It will be optimal when the RAM frequency matches the frequency supported by the motherboard and processor.

Let's look at an example. We connected DDR3-1800, but the board can support DDR3-1600 at most. Your RAM will work no higher than 1600 MHz, its resource will be consumed in an incomplete amount, and failures and errors may occur in the system.

Operating mode

These days, PCs are equipped with boards that support special modes of RAM operation. Some modes are most efficient at speed, so it's useful to take them into account when purchasing RAM.

Mode Types


Volume

Volume - important characteristic, a high indicator of this characteristic does not always lead to an increase in the performance of a computer/laptop. Still, volumes from and above 6 GB make sense, especially with weak disk system. Modern programs are consuming more and more memory.

Timings are time delays, indicated by numbers, for example, 3-3-3. This represents three parameters:

  • the time consumed to read the first bit from memory, i.e. the number of nanoseconds spent in the interval from sending to memory to the start of the data transfer itself (CAS Latency);
  • the time spent also reading the first bit, but this includes the nanoseconds of delay that exists between the beginning of opening a row and accessing the columns in it (RAS to CAS Delay);
  • the third digit means the number of ticks in the interval from the closing of one line to the opening of the next (RAS Precharge Time).

The throughput and performance of the system as a whole depend on these technical parameters. RAM works faster when the timings are reduced. They are measured in nanoseconds, from 2 to 9 ns. If the information contains only one digit, it indicates the first parameter - CAS Latency. Sometimes the manufacturer hides higher next parameters in this way.

The RAM frequency depends on the timings: the higher it is, the higher the timings. Better pick optimal ratio both characteristics. If the manufacturer indicates Low Latency models, it means that at high frequencies the RAM produces less latency than standard sticks, but such computer RAMs, of course, are more expensive; here you need to take into account, in addition to the criteria listed above, the state of your wallet.

Manufacturer

No less important when deciding how to choose RAM is the question of the manufacturer. The products of companies that have proven themselves in the market are popular: OCZ, Kingston, Corsair.

So, when choosing RAM for a computer or laptop, pay close attention to the task so that the purchase is useful and the device functions properly. full force, the RAM matched the board's requirements and ensured maximum performance.

If you want to buy a laptop or if the available amount of RAM is not enough for you, and even using the page file does not allow you to perform necessary tasks, then a reasonable question arises: how to choose RAM for a laptop. Let's figure out what characteristics you should pay attention to in order to be satisfied with the performance of your laptop.

RAM - random access memory.

What module do we need?

You only have to choose a form factor, because for laptops it is the same - SO-DIMM (double-sided memory module). The remaining characteristics may raise some questions, so let’s go over the main parameters.

Memory capacity: how much in grams?

If you are going to run modern games or graphics-intensive applications, then you need a lot of memory for storage and transfer temporary files. You can focus on the following parameters:

If you have an old one, then installing more than 8 GB of memory is pointless - the laptop will not work faster. However, if the processor allows you to increase the memory capacity to 8 GB or higher, then be sure to install a 64-bit version on your laptop Windows version, since x32 cannot work with RAM whose volume exceeds 4 GB.

How important are frequency and other parameters?

The higher the frequency, the faster the processor will receive and process data. Therefore, try with the highest possible frequency that the motherboard and processor support. To avoid compatibility problems, choose identical modules. If you are going to install several strips, it is better to immediately purchase a Kit set, which includes 2-3 modules with the same characteristics.

  • Do not buy DDR4 standard sticks - the technology has not yet been fully tested. DDR3 laptop RAM is still the best, proven and stable solution. The DDR5 standard does not exist at all - there is only GDDR5 video memory, which many mistakenly consider the fifth generation of DDR.
  • Do not buy cheap modules from unknown manufacturers. Guarantee period they work, but after a couple of years malfunctions may appear.
  • If there is support dual channel mode, take two smaller sticks, not one larger one (2 x 4 GB instead of 1 x 8 GB). This will improve productivity by about 15%.
  • If there is a significant difference in price, take memory with higher timings.

Timing is the time interval during which a command sent by the RAM controller is executed. The lower the timing, the better, but it affects the speed less than the frequency. Therefore, it is better to take a bar with a high frequency and slightly higher latency than the other way around.

We hope you have figured out how to choose RAM for a laptop. There is nothing complicated here - the main thing is not to chase numbers and brands, but to approach the choice practically and thoughtfully.
