In what order to install RAM. RAM slot

Two 4GB sticks are generally faster than one 8GB stick - this is an example.

If you have successfully selected and bought the RAM module you need, let's install it correctly into our computer. All the parts inside the system unit do not require significant physical effort for their operation, so relax a little. Before work, it will not be superfluous to familiarize yourself with the manual that came with your motherboard, it must have its own instructions for installing RAM.

• Note: If you have a laptop, then read the article -.

First of all, we remove static electricity from ourselves, touch our hands to the unpainted parts of your system unit.

We perform all actions on a turned off computer. Unplug the power cord from the electrical outlet. We remove the side cover of the system unit and find the slots for RAM on the motherboard. Usually there are from two to four. Each RAM slot has special latches on the edges on both sides, they must be carefully squeezed out to the sides.

Note: Some motherboards are designed in such a way that install RAM the video card will interfere with you, then remove it.

Now take a close look at any slot for installing RAM, it has a special protrusion.

Now take out the RAM module and you will see a special slot or recess on it.

So, we pushed aside two latches of the RAM slot, carefully insert our RAM module into the slot.

If you bought the RAM module correctly, then when you install the module into the slot intended for it on the motherboard, this cutout should definitely fall into the protrusion. If the notch and protrusion do not match, then the RAM module is not designed to work on this motherboard.

The module should hit the guides without any distortions, now is the most crucial moment, gently and gently press the module from above on both sides with thumbs, it should snap into place, and the latches should snap into place.

If the latches do not snap into place, look carefully to see if the module is fully inserted into the slot, if to the end, then fix the latch yourself. I think everything is clearly visible on the screenshots.

Let me remind you, if you have two RAM modules with the same size and the same characteristics, and the motherboard supports a two-channel RAM mode, insert the modules into the same colored slots.

We put the cover of the system unit back, connect all the cables and turn on the computer.

How to extract RAM

If you need to remove the RAM from the slot, it is very simple to do this, unlatch the latches and remove the RAM module.

Instructions

Determine how much memory is already installed. Go to the Start menu and select Settings, then Control Panel and System. Select the General tab. The amount of memory installed on your computer will be shown at the bottom of the page.

Determine what type and amount of memory you need to purchase. Check your user manual for the maximum amount of memory your computer can handle. The guide will also help you choose the type and speed of memory you need. Buy an operational memory online or at your local computer store.

Open the case computer... Refer to the instruction manual if necessary. Remove all metal rings, watches, or bracelets. Turn off the computer, unplug it from the electrical outlet, and then touch the metal chassis to discharge any static electricity. An antistatic wrist strap can also be used for this purpose.

Find the memory slots on the motherboard computer... If necessary, refer to the instruction manual. If there are no free slots, you will have to remove one or more of the installed memory cards in order to be able to add a new one. memory.

Install new memory... To do this, open the holders in the free slot and carefully insert the memory card into it. Make sure the memory card module is securely inserted into the slot and secure the holders.

Test the installed memory... Close the case and turn on the computer. If the computer starts beeping, then memory installed incorrectly. Then repeat step 5 to make sure that memory securely inserted into the slot. If the installation was successful, check that the system has detected a new amount of memory (step 1).

Increasing random access memory (RAM) significantly improves the performance of your computer. Moreover, it does not require knowledge about the filling, it is enough just to carefully install the module into the motherboard slot.

You will need

• - memory module;
• - screwdriver.

Instructions

Purchase the correct RAM module. Modern computers use DDR, DDRII and DDRIII strips, differing in connectors and operating speed. You can find out what type of memory is used in your PC in the passport that was issued upon purchase.

Users are often faced with the need to increase the amount of RAM when they start working with more demanding software. "Operative" is responsible for the temporary storage of data required to perform current processor operations. Read more about how to increase RAM in our material.

The amount of RAM depends on how easily and quickly the PC copes with work, performing several tasks at the same time.

The procedure for increasing the amount of RAM itself may consist in purchasing additional memory cards or replacing the already installed memory with a module of a larger volume. In this case, it is necessary to take into account such characteristics of RAM as type, clock frequency, and, of course, volume.

If you decide to install an additional RAM bar in your PC, then it must be of the same type as the one that is already installed in the device. In addition, you need to find out the maximum amount of RAM that is supported by the motherboard, processor.

The characteristics of the RAM installed in the PC can be found using special utilities, for example, Speccy or Everest. Alternatively, you can remove the cover of your PC case and conduct a visual inspection. If only the name of the module is indicated on the RAM bar, then using a network search you can find all the characteristics you need.

RAM type

Memory differs in speed: modules of a newer type can transfer more bits of information on each cycle of the memory bus. Also, different memory sticks differ visually.

Modern PCs use DDR2, DDR3 and DDR4 memory cards. The SDRAM and DDR types are older. And when upgrading a PC, it makes sense not to buy an additional bar of the same type, but to replace it with a module of a newer technology. In terms of money, it will not be much more expensive, but in terms of speed, it will be a tangible plus.

DDR3 differs from DDR2, for example, in lower power consumption. There is also a variety of DDR3L modules - with even lower power consumption.

Carefully read the characteristics of the motherboard before purchasing a new RAM module, since different types of memory cannot be inserted into the same slot on the motherboard due to the different places of the cutout on the strips. So, SDRAM memory (unlike DDR modules) has two notches on the bottom edge of the board and 144 pins. The DDR module has 184 pins, DDR2 and DDR3 have 240 pins, DDR4 has 288 pins, but the key is shifted from the center to the left edge of the bracket.

Frequency and timing

Frequency. This parameter determines the amount of data that can be transmitted in a certain time, that is, the speed of the RAM. The frequency of the RAM must match that supported by the computer motherboard.

Another important parameter that characterizes the speed of the RAM is timing. The delay in processing the operation inside the RAM depends on its value. In the name of a RAM module, it can be written as a sequence of four numbers, for example, 9-9-9-24, or CL and a numerical value - the first digit of a 4-digit sequence, that is, CL9 for the above example. The minimum timing is good for gaming and video editing computers. For PCs designed for simple daily tasks, timing has little effect on performance.

RAM slots

Before buying an additional RAM card, you need to find out if there is where to put it. And it depends on the number of free slots in your computer.

If your motherboard supports dual channel RAM, you can use this to improve performance. To do this, you need to purchase not one board of a larger volume, but two modules of the same characteristics. Manufacturers often offer such kits (Kit). For example, not one 8 GB module, but two 4 GB modules operating in dual channel mode. For users who add memory to play games or use heavy programs, this is important. If a PC is used to work with office software, a browser and to watch a movie, then you can safely buy one stick of RAM.

Also today there are motherboards and sets of RAM (Kits) that support the three-channel mode of operation.

What else needs to be considered

When choosing RAM, you also need to take into account the operating system on which you will work, since the minimum amount of required RAM depends on it. Windows 7 and 8 32-bit requires at least 1 GB of RAM, Windows 7 and 8 64-bit requires at least 2 GB (GB), and Windows XP requires at least 64 MB of RAM.

What else should you pay attention to when choosing RAM? To the manufacturer. It is better to choose boards from trusted manufacturers, for example, Corsair, Kingston, Hynix, Transcend, OCZ.

Installation

After you open the case of the turned off PC and remove the static charge from your hands, you can start installing additional or new RAM module / modules.

1. If you bought a set of two boards to work in dual channel mode, check the motherboard specifications in which slots you need to install them.

2. If you completely change the RAM, remove the memory: open the slot latches on both sides of the module, gently holding the module by the side edges, and pull it out of the slot.

3. Insert the new module into the desired slot, aligning the notch on the memory card with the tab on the connector. Press down lightly on the module until the clips secure it.

4. Repeat the last step with the rest of the memory modules, if any.

5. Close the PC case.

If your computer is slow, freezes when working with programs and playing games, then one of the best ways to improve its performance at the hardware level is to install additional RAM on the computer. In this article, we will walk you through the step by step the process of adding, replacing RAM.

Choosing the right type of RAM

Before heading to the store to buy a new memory module, you need to find out what type of RAM your motherboard supports. There are the following types of RAM: DDR, DDR2, DDR3, DDR3 L and a new type of DDR4. They differ in size, so if you buy the wrong type, it simply won't fit into the connector. There is also a division into DIMM (for desktops) and SODIMM (for laptops) form factors.

To find out the type, you need to carefully read the instructions for the motherboard. If you already have memory modules installed, take one and look for the parameter sticker. The DDR type is indicated on it. Most modern computers have DDR2 and DDR3 memory installed.

We count the number of slots for RAM on the motherboard

The number of slots for memory modules on the motherboard can be 2,4,6,8, and even more on the server motherboard. Most motherboards have 2-4 connectors. You should pay attention to the maximum amount of memory that your motherboard supports.

Choosing a manufacturer

Many companies are involved in the development of RAM. The results of their labor differ in both price and quality. We do not recommend purchasing memory from little-known manufacturers.

In recent years, the following manufacturers have been popular:

We purchase RAM

Going to buy at a specialized computer store, you need to know exactly what kind of RAM you need and whether it will be compatible with the motherboard.

Preparing to install RAM

Step 1... Turn off the power to the computer. Disconnect all cables and cords connected to the back of the chassis.

(Monitor, mouse, keyboard, etc.)

Step 2... Remove the side cover from the case. Position the computer case for comfortable handling. It will be most convenient if you lay it on its side. Free up access to the motherboard by gently pushing aside the adjacent wires.

Step 3... Next, you need to get rid of static charges. They can damage the components installed on the motherboard. To do this, simply touch the body or the battery with your hand. For some, this advice may seem ridiculous, someone will say that nothing will happen and nothing will be damaged, but as the saying goes, "God takes care of him," so it is better to be on the safe side and heed the advice.

Step 4... Locate the RAM connectors on the motherboard. In modern motherboards, manufacturers make 2, 4 connectors. They are equal in size and parallel to each other. You can see how they look in the photo below.

Step 5... If you are replacing an old memory with a new one, then you need to remove the old module. Press down gently on the two outermost white latches. The module is released and can be easily removed.

Step 6... Take a new memory strip, while trying not to touch the microcircuits and contacts located on it.

Not much in laptops is upgraded (or at least difficult), but increasing the amount of RAM is easy enough in many cases. This step-by-step instruction on how to increase the RAM of a laptop is aimed primarily at novice users.

What RAM is needed for a laptop

Before buying memory sticks (RAM modules) to increase the RAM on a laptop, it would be nice to know how many RAM slots there are and how many of them are occupied, as well as what type of memory you need. If you have Windows 10 installed, then this can be done very simply: start the task manager (you can from the menu that appears by right-clicking on the Start button), if the task manager is presented in a compact form, click the "More" button below, then go to the tab "Performance" and select "Memory".

At the bottom right, you will see information about how many memory slots are used and how many are available, as well as data on the memory frequency in the "Speed" item (from this information you can find out if DDR3 or DDR4 memory is used on a laptop, also the type of memory is indicated at the top of the spacing ). Unfortunately, these data are not always accurate (sometimes the presence of 4 slots or sockets for RAM is displayed, although in fact there are 2 of them).

In Windows 7 and 8, there is no such information in the task manager, but the free CPU-Z program will help us here, showing in detail information about a computer or laptop. You can download the program from the developer's official website at https://www.cpuid.com/softwares/cpu-z.html (I recommend downloading the ZIP archive to run CPU-Z without installing it on your computer, it is in the Download column on the left).

After downloading, run the program and pay attention to the following tabs, which will help us in the task of increasing the laptop's RAM:

Note: in some cases CPU-Z may show 4 memory slots for laptops, in which there are actually only 2 of them. Take this into account, as well as the fact that almost all laptops have exactly 2 slots (except for some gaming and professional models).

For example, from the screenshots above, you can draw conclusions:

• The laptop has two slots for RAM.
• One is occupied by a 4 GB DDR3 PC3-12800 module.
• The used chipset is HM77, the supported maximum amount of RAM is 16 GB (this is searched on the Internet by chipset, laptop model or motherboard).

This way I can:

• Buy another 4GB RAM SO-DIMM (laptop memory) DDR3 PC12800 and upgrade the laptop memory to 8GB.
• Buy two modules, but 8 GB each (4 will have to be removed) and increase the RAM to 16 GB.

RAM for laptop

To work in dual-channel mode (and this is preferable, because the memory works faster, with twice the frequency), two modules of the same volume are required (the manufacturer may be different, if, for example, we use the first option) in two slots. Also keep in mind that the maximum amount of supported memory is based on all slots: for example, the maximum memory is 16 GB and there are two slots, this means that you can install 8 + 8 GB, but not one 16 GB memory module.

In addition to these methods, to determine what memory is needed, how many free slots there are and how much it can be increased to the maximum, you can use the following methods:

How to install RAM in a laptop

In this example, we will consider the option of installing RAM in a laptop, when it was directly provided by the manufacturer - in this case, access to the memory slots is facilitated, as a rule, there is a separate cover for this. Previously, it was almost the standard for laptops, now, in the pursuit of compactness or for other reasons, separate technological covers for replacing components (eliminating the need to remove the entire lower part) are found only on some devices of the corporate segment, workstations and other laptops that go beyond the framework of the consumer segment.

Those. in ultrabooks and compact laptops, there is nothing like this: you need to unscrew and carefully remove the entire bottom panel, and the disassembly scheme may differ from model to model. Moreover, for some laptops, such an upgrade will void the warranty, take this into account.

Note: if you do not know how to install memory in your laptop, I recommend to go to YouTube and search for the keyword "laptop_model ram upgrade" - most likely you will find a video where the whole process, including the correct removal of the cover, will be demonstrated visually. I am citing an English-language request for the reason that in Russian it is rarely possible to find a disassembly of a particular laptop and a memory installation.

1. Unplug the laptop, including from the outlet. It is also advisable to remove the battery (if it cannot be disconnected without opening the laptop, then disconnect the battery first after opening it).
2. Use a screwdriver to open the cover, you will see the memory modules installed in the slots. If you need to remove not a separate cover, but the entire rear panel, try to find instructions on how to do it correctly, as there is a risk of damaging the case.
3. RAM modules can be removed, or new ones added. When removing, please note that, as a rule, memory modules are fixed on the side with latches that you need to bend.
4. When inserting memory, do it tightly, until the latches snap into place (on most models). All this is comparatively not difficult, you cannot make a mistake here.

Upon completion, return the cover to its place, install the battery, if necessary - connect to the mains, turn on the laptop and check if the BIOS and Windows can see the installed RAM.

If your computer is slow, freezes when working with programs and playing games, then one of the best ways to improve its performance at the hardware level is to install additional RAM on the computer. In this article, we will walk you through the step by step the process of adding, replacing RAM.

Basic recommendations applicable to all types and types of memory:
- It is best to install DIMMs with the same amount of memory;
- modules must match in frequency (Mhz), if you install modules with different operating frequencies, then in the end all of them will operate at the frequency of the slowest memory;
- it is desirable to combine timings, latencies (latencies) of memory for installed memory cards;
- it is better to select modules from one manufacturer and one model.

Some enthusiasts try to buy modules from the same batch, but this, it seems to me, is already a perversion!

These tips are not strictly followed, situations are different. If memory modules differ from each other in manufacturer, size and frequency of operation, this does not mean at all that they will not work. In this case, there are no special memory layout secrets - you just need to install them.

There are also no peculiarities when installing outdated types of SDRAM memory (there is one rule - the more, the better).

But in modern computers, motherboards support special modes of operation of RAM. It is in these modes that the speed of the RAM memory will be most efficient. Therefore, for the best performance, consider the DIMM behavior and proper installation. Let's take a look at the most common modes of operation of RAM today.

Operating memory modes

SINGLE CHANELL MODE

Single Mode (single-channel or asymmetric mode) - this mode is implemented when only one memory module is installed in the system or all DIMMs differ from each other in terms of memory size, operating frequency, or manufacturer. It doesn't matter in which slots and which memory to install. All memory will run at the speed of the slowest memory installed.

If there is only one module, then it can be installed in any memory slot:

Two or three different memory modules can also be installed in any configuration:

Such a mode is more of a necessity when there is already RAM in the presence, and in the first place is increasing the amount of memory and saving money, and not achieving the best PC performance. If you are just buying a computer, it is of course best to avoid this kind of memory installation.

DUAL CHANELL MODE

Dual Mode (two-channel or symmetric mode) - the same amount of RAM is installed in each DIMM channel. Modules are selected according to the frequency of operation. On motherboards, the DIMM slots for each channel are color-coded. Next to them is the name of the connector, and sometimes the channel number. The purpose of the connectors and their location by channel must be indicated in the motherboard manual. The total amount of memory is equal to the total amount of all installed modules. Each channel is served by its own memory controller. System performance is increased by 5-10%.

Dual Mode can be implemented using two, three or four DIMMs.

If two identical RAM memory modules are used, then they should be connected to the same connectors (in the same color) from different channels. For example, install one module in the slot 0 channel A and the second into the connector 0 channel B:

That is, to enable the mode Dual Channel(alternating mode) the necessary conditions must be met:
- the same configuration of DIMM modules is installed on each memory channel;
- memory is inserted into balanced channel connectors ( Slot 0 or Slot 1) .

Three memory modules are installed in the same way - the total amount of memory in each channel is equal to each other (memory in the channel A equal in volume in the channel B):

And for four modules the same condition is met. There are two parallel dual modes working here:

TRIPLE CHANELL MODE

(three-channel mode) - the same amount of RAM is installed in each of the three DIMM channels. Modules are selected in terms of speed and volume. Motherboards supporting three-channel memory operation usually have 6 memory slots (two for each channel). Sometimes there are motherboards with four connectors - two connectors make up one channel, the other two are connected to the second and third channel, respectively.

With six or three sockets, setup is just as easy as with two-channel mode. With four memory slots installed, three of which can work in, the memory should be installed in these slots.

(flexible regime) - allows you to increase the performance of the RAM, when installing two modules of different sizes, but the same frequency of operation. As in the dual-channel mode, memory cards are installed in slots of the same name on different channels. For example, if there are two memory sticks of 512Mb and 1Gb, then one of them should be installed in the slot 0 channel A, and the second into the slot 0 channel B:

In this case, the 512MB module will operate in dual mode with 512Mb of the second module, and the remaining 512MB from the 1GB module will operate in single-channel mode.

That is, in principle, all the recommendations for combining RAM. Of course, there may be more layout options, it all depends on the amount of RAM, the model of the motherboard and on your financial capabilities. Also, motherboards with support for four-channel mode work memory - this will give you maximum computer performance!

Every computer owner has thought about improving it at least once. Some just change the processor, someone collects and re-solders the insides of the video card. But it is easier and cheaper to overclock your computer. This can be done by adding RAM to it. This method does not require special training or expensive purchase of a new processor. But before engaging in a practical solution to the question: "How to add RAM to a computer?", You need to figure out what it is and why you need it.

What is RAM

Random access memory (RAM, RAM - random access memory) is the place where all temporary data about the operation of programs is stored. Outwardly, the OP looks like several different microcircuits connected to the motherboard. It serves as a temporary storage for all running programs and has a high speed of writing and reading data.

It should be noted that RAM is fundamentally different from hard disk memory. RAM stores information only as long as the device is connected to the power supply, that is, as soon as the computer is turned off, all data in the random access memory will be erased. Hard disk memory stores information until you delete it.

Modern RAMs are very voluminous and allow the computer to work on many tasks at the same time. But their variety is confusing for the inexperienced user. Let's try to figure out how to add RAM to your computer.

When should you change your RAM?

Sometimes the user may not notice the signals with which the technician notifies that more strength is needed to complete routine tasks. It is easy to understand the signals, the main ones are in plain sight. You need to change the RAM if:

• the computer starts to slow down when executing programs;
• a laptop or desktop computer takes a long time to load and load programs;
• sites with “heavy” graphics and animation are not loaded;
• you need to install powerful games or complex programs, as well as run multiple processes at the same time.

So, is it possible to add RAM to a computer and what are the ways to do it?

Ways to increase RAM

It is quite possible to improve the performance of equipment, today there are three main ways to increase the RAM on a computer:

• method of replacing strips;
• Installing Ready Boost;
• pumping OP.

All methods are simple, even a beginner can handle them. However, each technique has its own nuances.

Hardware method: RAM modules

The first method involves installing new RAM strips to replace the old ones. But not everything is so smooth here: the new trims must be compatible with the motherboard, as well as the processor. To use this method, you need to know exactly how to properly add RAM to your computer.

In general, the procedure is as follows:

• remove the cover of the system unit;
• find the RAM mounts on the motherboard;
• remove the old memory by pulling back the clips;
• install new RAM;
• fix the bar with the holders.

This method allows you to quickly and efficiently add performance to your PC.

Hardware Method: Ready Boost System

The essence of the method for improving the computer is that a USB flash drive is connected to the USB input, which will serve as a source of additional RAM. Special software (Ready Boost), supported by Microsoft Windows 7 and higher, can turn USB media into a data processing device.

Many users, when using the option with the Ready Boost installation, immediately try to take a larger drive, but this is not always necessary. The program can use external drives up to 256 GB on 64-bit Windows and only 4 GB on other operating systems that support this function.

Please note that when using this method, you must never disconnect the USB drive. The RAM addition technique can be used as an auxiliary, but it is worth choosing something else as a permanent solution.

Programmatic method: swap file

Is it possible to add RAM to a computer using only the PC's reserves? Newer versions of Windows have a very useful virtual memory feature. Essentially, these are hard drive reserves. To install, you need to go to the address: My Computer - Properties - Advanced Settings, then select the "Performance" option, and in it - "Additional memory". Then you should set the required values. Owners of older processors will benefit from this method.

When it becomes clear how to add a bar of RAM to the computer, correctly connect a USB flash drive or use computer resources, you can immediately start work, but first you should evaluate the advantages and disadvantages of each method. So, the most effective option would be to replace the RAM strips.

Choosing RAM: motherboard compatibility

Before purchasing new trims, you should check the need to increase the performance of your computer. Technology can slow down for various reasons, so first you need to check your laptop or PC for viruses that eat up a huge share of the RAM. Next, you can clean your computer from unnecessary or obsolete files and remove from startup programs that are not needed when you turn on your PC. If everything is in order, you can choose a suitable device.

When choosing RAM, you must take into account that the motherboard must be compatible with it. In order to understand which temporary memory strips are suitable for the motherboard, you need:

• go to the motherboard manufacturer's website;
• select the required model;
• open instructions;
• see a list of recommended options for OP planks.

After the list of models has been studied, you can start choosing the appropriate option for other parameters.

Technical parameters of RAM strips

After determining the compatibility, you should understand the required technical parameters. If you delve into all the subtleties and follow the recommendations, it will not be difficult to solve the question "how to install / add RAM".

The type and amount of memory, design features of the bar, operating modes, frequency and speed of operation, as well as some other parameters should be considered in detail.

Memory type

Today there are several types of RAM: some are outdated, others are so innovative that not all PCs support them.

The best selling (and therefore popular) are DDR3, or Double-Data-Rate, the third version. Unlike the previous generation, DDR3 heats up less and has up to 2400 megahertz clock frequencies. Also, this type of RAM is distinguished by low power consumption.

Better not to mess with DDR1 and DDR2 memory, as they are outdated. There is also the newest type - DDR4, which has a clock speed of up to 4200 megahertz. This type of memory may not be supported by all devices.

Form factor

The form factor is the design features of the RAM strip. There are strips for laptops (SO-DIMM) and for PCs (DIMM). The former are usually small in size and with fewer contacts. When choosing RAM for a PC or laptop, these characteristics must be supported by the motherboard.

Frequency and baud rate

Frequency and transmission rate are some of the most important characteristics that should be given special consideration when choosing. Frequency refers to the amount of information that a computer can transmit in a given time. Accordingly, the higher the indicator, the better the performance of the PC. When choosing, you also need to build on those parameters that are supported by the motherboard.

Memory modes

The new RAM has special modes that affect the data transfer rate. There are four main types of modes:

• Single Channel Mode - works when installing one bar or with modules of different volumes, this is the slowest mode.
• Dual Mode is symmetrical, the connectors are equipped with strips of the same volume, and the speed is doubled in comparison with the first mode.
• Triple Mode - uses three channels, while all have the same trim levels, however, the data transfer rate of triple mode may turn out to be weaker than that of Dual.
• Flex Mode is a flexible mode, which implies the installation of two bars with different volumes, but the same frequency.

The most popular option at the moment is the symmetrical mode (Dual Mode).

Memory

Performance is as important as data transfer rate and remains one of the key today. The bottom line is extremely simple: the larger the memory, the faster the PC runs.

When choosing a RAM strip, you should take into account the goals and tasks for which the PC will be used in the future. If this is working with office programs and Internet surfing, then 2 Gigabytes will be enough. Work involving the use of heavy programs, such as graphic editors or video processing software, then 4 GB of RAM will be enough. For modern games, 8 GB of RAM is sufficient. Today, RAM has been developed with a large amount, but there are very few programs that allow you to use the full potential of such devices, and they are rarely used by average users.

Timings

Timing is the time delay between a command sent to the device and its execution. The parameter also depends on how fast the computer or laptop will work. If the values ​​are large, respectively, and the delay is significant, the RAM processes the information slowly. The shorter the latency, the higher the processing speed.

There is also a direct relationship between the timing and frequency of the OP. The higher the frequency, the greater the timings. Therefore, when choosing, you should be guided by the golden mean.

Manufacturer

There are many PC component manufacturers. The best option is to be guided by brand reputation, performance and reliability reviews, and company pricing. At the moment, the most popular are:

• Corsair.
• Adata.
• Kingston.
• GOODRAM.
• Kingmax.
• Transcend.

Each product provides a wide range of models, so it is not difficult to choose a RAM according to the required characteristics, quality and price. And in general, figuring out how to add RAM to a computer and how to choose RAM sticks is not difficult. It is enough to superficially navigate the technical characteristics.

Important information

Before starting self-installation, you must study all the recommendations and instructions. The following tips are common:

1. When replacing the strips, be sure to insert them all the way and fix them with clips. Otherwise, the computer will not see the components and will not boot.
2. When choosing a RAM frequency, consider the support for it by the board and the OS. Otherwise, the computer may malfunction.
3. Even if the new RAM is necessary for powerful games, you shouldn't spend the entire allocated budget on boards larger than 8 GB.
4. Care must be taken when working on the installation, as the planks are fragile. It is also imperative to disconnect the PC from the network and carry out all manipulations exclusively with dry hands.
5. The system may have a limit on full memory usage. In this case, even installing the slats will not help add more RAM. It turns out the following: the user added RAM, the computer does not use it. Also, one of the reasons is often a limitation in the motherboard. In addition, the board may not be installed correctly.

If everything is done correctly, then the question is: "How to add RAM to the computer?" will be solved quickly and without additional difficulties.

Must be manufactured in a case that already houses the motherboard and processor. Something like this:

In the photo above, we see that the RAM has already been installed. We also see the installed motherboard and power supply (indicated by an arrow).

In general, I must say that if you buy a case for a computer, then, often, it is supplied already complete with a power supply unit and you do not need to install it. But in any case, the very procedure for installing the power supply into the case is not difficult: you place it in the space provided for this (usually at the top of the system unit)

and securely fasten with four screws on the back wall.

But we will not connect the power supply for now, but we will start installing the RAM. In the figure below, we see how this is done correctly. It is necessary to snap off the plastic clips on the connector itself, carefully insert the RAM module into the groove that goes through the entire connector and gently but firmly press on it perpendicularly downward until it clicks and fits snugly into the slot. In this case, the plastic clips on the sides will snap into place, if not, look carefully to see if the memory bar has "sat down" as you need it to and snap them yourself.

At the same time, the fan power connector "CPU_FAN" is circled in the figure.

Attention! The computer could be damaged! Installing RAM is a responsible business... Therefore, before installing it, it is very important to make sure that you are installing a memory module that is physically compatible with it. For example, the DDR2 slot is equipped with only DDR2 memory, DDR3 slots - only DDR3 memory, etc.

If, when installing the RAM, it was found that there is no sticker (special sticker) on it indicating the type of memory, you can navigate purely visually by the "key". A key is a special "cut" dividing it into several parts at the bottom of the RAM. Accordingly, each memory slot has a protrusion at the same location. The "key" serves as a kind of protection against attempts to install RAM in a slot that is unsuitable for its physical characteristics.

This is how the two "keys" look in the memory of the old standard "SD-RAM":

If you do not want to open your computer, then to determine what type of RAM is installed in it, I recommend using the "CPU-Z" program. It will show what type of components your pc consists of. We analyzed the work of this wonderful utility.

So, we install all the memory chips at our disposal into the slots. On modern motherboards, they are often marked with different colors (two yellow slots, two red). This is a mode of dual-channel use of RAM, which slightly increases its bandwidth.

To use the two-channel (or three-channel) mode of RAM, we need to insert the strips in pairs: we install two identical modules in connectors of the same color, then two others - we install them in connectors of a different color. To get the maximum effect, the memory chips should really be the same by its operating characteristics of frequency, timings, delays "CAS" and "RAS". Ideally, they should be purchased from a computer company at the same time :)

Moreover, the colors of the memory slots do not alternate, for example: yellow, red, yellow, red.

We snap all the clips, check that all the memory modules "sit" in the slots exactly (the memory chips should be on the same height line, without raised edges and "protruding" latches).

This is how the RAM is installed in such a simple way. As you can see, everything is simple :)

Users are often faced with the need to increase the amount of RAM when they start working with more demanding software. "Operative" is responsible for the temporary storage of data required to perform current processor operations. Read more about how to increase RAM in our material.

The amount of RAM depends on how easily and quickly the PC copes with work, performing several tasks at the same time.

The procedure for increasing the amount of RAM itself may consist in purchasing additional memory cards or replacing the already installed memory with a module of a larger volume. In this case, it is necessary to take into account such characteristics of RAM as type, clock frequency, and, of course, volume.

If you decide to install an additional RAM bar in your PC, then it must be of the same type as the one that is already installed in the device. In addition, you need to find out the maximum amount of RAM that is supported by the motherboard, processor.

The characteristics of the RAM installed in the PC can be found using special utilities, for example, Speccy or Everest. Alternatively, you can remove the cover of your PC case and conduct a visual inspection. If only the name of the module is indicated on the RAM bar, then using a network search you can find all the characteristics you need.

RAM type

Memory differs in speed: modules of a newer type can transfer more bits of information on each cycle of the memory bus. Also, different memory sticks differ visually.

Modern PCs use DDR2, DDR3 and DDR4 memory cards. The SDRAM and DDR types are older. And when upgrading a PC, it makes sense not to buy an additional bar of the same type, but to replace it with a module of a newer technology. In terms of money, it will not be much more expensive, but in terms of speed, it will be a tangible plus.

DDR3 differs from DDR2, for example, in lower power consumption. There is also a variety of DDR3L modules - with even lower power consumption.

Carefully read the characteristics of the motherboard before purchasing a new RAM module, since different types of memory cannot be inserted into the same slot on the motherboard due to the different places of the cutout on the strips. So, SDRAM memory (unlike DDR modules) has two notches on the bottom edge of the board and 144 pins. The DDR module has 184 pins, DDR2 and DDR3 have 240 pins, DDR4 has 288 pins, but the key is shifted from the center to the left edge of the bracket.

Frequency and timing

Frequency. This parameter determines the amount of data that can be transmitted in a certain time, that is, the speed of the RAM. The frequency of the RAM must match that supported by the computer motherboard.

Another important parameter that characterizes the speed of the RAM is timing. The delay in processing the operation inside the RAM depends on its value. In the name of a RAM module, it can be written as a sequence of four numbers, for example, 9-9-9-24, or CL and a numerical value - the first digit of a 4-digit sequence, that is, CL9 for the above example. The minimum timing is good for gaming and video editing computers. For PCs designed for simple daily tasks, timing has little effect on performance.

RAM slots

Before buying an additional RAM card, you need to find out if there is where to put it. And it depends on the number of free slots in your computer.

If your motherboard supports dual channel RAM, you can use this to improve performance. To do this, you need to purchase not one board of a larger volume, but two modules of the same characteristics. Manufacturers often offer such kits (Kit). For example, not one 8 GB module, but two 4 GB modules operating in dual channel mode. For users who add memory to play games or use heavy programs, this is important. If a PC is used to work with office software, a browser and to watch a movie, then you can safely buy one stick of RAM.

Also today there are motherboards and sets of RAM (Kits) that support the three-channel mode of operation.

What else needs to be considered

When choosing RAM, you also need to take into account the operating system on which you will work, since the minimum amount of required RAM depends on it. Windows 7 and 8 32-bit requires at least 1 GB of RAM, Windows 7 and 8 64-bit requires at least 2 GB (GB), and Windows XP requires at least 64 MB of RAM.

What else should you pay attention to when choosing RAM? To the manufacturer. It is better to choose boards from trusted manufacturers, for example, Corsair, Kingston, Hynix, Transcend, OCZ.

Installation

After you open the case of the turned off PC and remove the static charge from your hands, you can start installing additional or new RAM module / modules.

1. If you bought a set of two boards to work in dual channel mode, check the motherboard specifications in which slots you need to install them.

2. If you completely change the RAM, remove the old memory card: open the slot latches on both sides of the module, gently holding the module by the side edges, and pull it out of the slot.

3. Insert the new module into the desired slot, aligning the notch on the memory card with the tab on the connector. Press down lightly on the module until the clips secure it.

4. Repeat the last step with the rest of the memory modules, if any.

5. Close the PC case.

A few days ago I "freaked out" - I'm tired of buying parts for the future home "supercomputer". I took and at once purchased the remaining parts - the motherboard, processor and RAM.

I'll tell you today how to choose RAM in a computer and even how to install it correctly.

What is RAM

Before choosing RAM for a computer, you need to clearly understand what it is in general.

The RAM in a computer is one of the components, along with the central processor and SSD-disk, which is responsible for the system's performance.

The official definition goes something like this: RAM (random access memory) is a volatile part of a computer system that temporarily stores the input, output and intermediate data of programs and the operating system.

But, as always, I will try to convey this definition to you in simple language ...

The processor is the brain of the computer that processes all information. HDD ( or SSD drive) stores all data (programs, photos, movies, music ...). Random access memory is an intermediate link between them. It pulls up the data that needs to be processed by the processor.

Why "pull up"? Why not just take them off the hard drive? The fact is that the RAM works many times faster than even an SSD drive.

What data the processor may need soon is determined by the operating system itself, automatically. She is very smart, so they don't talk about her.

RAM types

When mammoths were still walking on the ground, the RAM was divided into SIMM and DIMM - just forget about these types of RAM, they have not been produced and used for a long time.

Then DDR was invented (2001). There are also computers with this type of memory. The main difference from DDR2 and DDR3 is the number of contacts on the DDR memory board, there are only 184 of them. This type of RAM is much slower than its modern counterparts (DDR2 and DDR3).

DDR2 (2003) has a larger number of contacts (240 pieces), thanks to which the number of data streams has expanded and the transfer of information to the processor has noticeably accelerated. The maximum DDR2 frequency is 1066 MHz.

DDR3 (2007) is the most common type of RAM in modern computers. They left the number of contacts alone (240), but made them electrically incompatible. Maximum frequency DDR3 - 2400 MHz ... This type of memory also has lower power consumption and higher bandwidth.

DDR3 is 15-20% faster than DDR2.

DDR2 and DDR3 strips have different key locations, they are not interchangeable ...

Form factor of ram strips

RAM sticks for laptops (SODIMM) and desktop computers (SDRAM) are different in size and appearance. For laptops, they look like this ...

... and for stationary home computers, something like this ...

This is where their differences (mostly) end. The characteristics that you need to know to choose RAM are absolutely the same for these two types.

RAM size

In the last century, the amount of RAM was measured in kilobytes and megabytes (it's even funny to remember). Today - in gigabytes.

This parameter determines how much temporary information will fit into the RAM chip. Everything is relatively simple here. Windows itself, during its work, consumes about 1 GB of memory, so there should be more of it in the computer.

2 GB - may be enough for a budget computer (movies, photos, Internet)

4 GB - suitable for more demanding programs, games at medium and maximum quality settings

8 GB - will handle heavy games at maximum quality settings or very memory-intensive programs * DANCE *

16 GB - the newest modern and heavy games, as well as special professional monster programs will "fly"

32 GB - You have nowhere to put your money? Send them to me.

It is very important to take into account that ordinary 32-bit Windows operating systems "do not see" memory more than 3 GB and, accordingly, do not use it. If you buy more than 3 GB of RAM, you MUST install a 64-bit system.

RAM frequency

Inexperienced users are often limited by its size when choosing a RAM, but memory frequency is no less important. It determines at what speed the data exchange with the processor will be carried out.

Modern conventional processors run at 1600 MHz. Accordingly, it is advisable to buy memory with such a frequency, not higher (1866 MHz is possible). The difference between 1333 MHz and 1600 MHz is almost imperceptible "by eye".

As for the memory sticks with a frequency of 2133 MHz and higher, they themselves cost wild money, for their full-fledged operation you need special motherboards that cost wild money, and most importantly, you need a processor with an unlocked multiplier (supporting overclocking), which costs ...

Moreover, all this disgrace will be very hot (you need a powerful cooling system (preferably water), which costs ...) and consume a lot of energy. This is the choice of crazy gamers.

By the way, the increase in computer performance with such overclocking will be only from 10 to 30%, and you will spend three times more money. Do you need it?

RAM timing

The "terrible" parameter of RAM that very few people know about and which is rarely taken into account when choosing memory, but in vain.

Latency (timing) is the time delay of the signal. It is measured in ticks. Timings can take values ​​from 2 to 13. They determine the bandwidth of the "processor-memory" section and, as a result, the speed of the system, albeit just a little bit.

The lower the timing value, the faster the RAM works. For example, I purchased memory with timing values ​​9-9-9-24, but there is also faster memory, of course.

RAM timings can be adjusted in BIOS when overclocking the system (it is not recommended to do this for inexperienced users).

And at the end of the article, as I promised at the beginning, I'll tell you ...

How to properly install RAM in a computer

Before the procedure, be sure to turn off the computer and disconnect the power cord from the system unit.

After installing the memory, you do not need to make any settings in the system. The system will recognize it and start using it.

Memory is easiest to install in a laptop (it can be more difficult to open the back cover). In laptops, the RAM is in a horizontal position, lies.

Just lift and pull it out of the grooves, insert a new one until it stops. The lock on the bar (slot) will not allow you to make mistakes when installing ...

In stationary computers, this process is a bit more complicated. The memory stands vertically to the motherboard and is clamped by latches.

To remove the bar, it is enough to spread these latches to the sides and it will jump out of the slot by itself. Installation will also take you 2 seconds - bring the bar to the slot, match the lock (slot) on the bar with a jumper in the slot and insert it all the way (hear a click - these latches will clamp the bar).

It is very important not to confuse the snap of the clips with the crunch of a broken motherboard.

Dual channel memory mode

Many users complain that the new programs on their personal computers do not work as efficiently and quickly as the old ones. There is nothing surprising here, new software requires a lot of power, which you may not have, you should think about increasing the amount of RAM, we will look at how to do this today.

The first thing to do is to determine the type of memory we use, you can do this with the employer of various programs available on the Internet or check it in your BIOS (section Main, or Infomation, depending on the manufacturer).
You should determine the type, operating frequency, manufacturer (DDR, DDR2, DDR3, DDR4, DIMM, soDIMM).

The next step is to check for additional slots for installing RAM. Some budget versions of laptops have only one slot for installing RAM, so you will have to replace the bracket with a more powerful one.

Installation of operational both on desktop versions and on portable computers looks like one procedure. You need to turn off the computer, open the cover to access the motherboard, wipe the mat slots. The boards and contacts are operational from dust and possible residues, and install. Reboot the system and enter BIOS to check and configure our RAM.

For desktop versions, it should be remembered that the motherboard can have so-called dual channels (dual channel memory), here for the operation of the operating system and the whole PC, you need to install it in the correct slots.

Another recommendation, if you decide to buy and install a RAM, in order to avoid conflicts in work, try to take it from the same manufacturer, and with the technical characteristics that you have.

In this article, we will consider the issues of choosing and how to install RAM and its competent layout in the motherboard connectors.

- install memory modules with the same size;
- modules must match in frequency (Mhz), otherwise they will all work at the frequency of the slowest memory;
- combine timings, latencies (delays) of memory;
- memory modules are better than one manufacturer and one model.

All these tips do not have to be strictly followed, cases are different. Even if memory modules differ from each other in terms of manufacturer, volume and frequency of operation, this does not mean that they will not work. In this case, there are no special memory layout secrets - you just need to install them.

There are also no peculiarities when installing outdated types of SDRAM memory (here the basic rule is that the more, the better).

But in modern computers, motherboards support special modes of operation of RAM. It is in these modes that the speed of the RAM will be the most efficient. Therefore, to achieve the best performance, you should take into account the modes of operation of the memory modules and their correct installation.
Next, we will consider the most common operating modes today.

Operating memory modes

SINGLE CHANELL MODE

Single Mode (single-channel or asymmetric mode) - this mode is enabled when only one memory module is installed in the system or all modules differ from each other in terms of memory size, operating frequency or manufacturer. It doesn't matter in which slots and which memory to install. All memory will run at the speed of the slowest memory installed.

If there is only one module, then it can be installed in any memory slot:

Two or three different memory modules can also be installed in any configuration:

Such a mode is more of a necessity when there is already RAM in the presence, and in the first place is increasing the amount of memory and saving money, and not achieving the best computer performance. If you are just about to buy a computer, it is best to avoid this kind of memory installation.

DUAL CHANELL MODE

Dual Mode (two-channel or balanced mode) - the same amount of RAM is installed in each channel. Modules are selected according to the frequency of operation. For ease of installation, on motherboards, the DIMM slots for each channel are color-coded. And next to them is the name of the connector, and sometimes the channel number. Also, the purpose of the connectors and their location along the channels must be indicated in the motherboard manual. The total amount of memory is equal to the total amount of all installed modules. Each channel is served by its own memory controller. System performance is increased by 5-10% compared to single-channel mode.

Dual Mode can be implemented using two, three or four DIMMs.

If two identical memory modules are used, they should be connected to the same connectors (in the same color) from different channels. For example, install one module in slot 0 of channel A, and the other in slot 0 of channel B:

That is, to enable the Dual Channel mode (alternating mode), the necessary conditions must be met:
- the same configuration of DIMM modules is installed on each memory channel;
- memory is inserted into balanced channel slots (Slot 0 or Slot 1).

Three memory modules are installed in the same way - the total amounts of memory in each channel are equal to each other (the memory in channel A is equal in volume to channel B):

And for four modules the same condition is met. There are two parallel dual modes working here:

TRIPLE CHANELL MODE

Triple Mode - The same amount of RAM is installed in each of the three DIMM channels. Modules are selected in terms of speed and volume. Motherboards supporting three-channel memory operation usually have 6 memory slots (two for each channel). Sometimes there are motherboards with four connectors - two connectors make up one channel, the other two are connected to the second and third channel, respectively.

With six or three RAM slots, setup is as easy as dual-channel. With four memory slots installed, three of which can operate in Triple Mode, the memory should be installed in these slots.

FLEX MODE

Flex Mode (flexible mode) - allows you to increase the performance of the RAM when installing two modules of different sizes, but the same frequency of operation. As in the dual-channel mode, memory cards are installed in slots of the same name on different channels. For example, if there are two 512Mb and 1Gb memory strips, then one of them should be installed in slot 0 of channel A, and the other in slot 0 of channel B:

In this case, the 512MB module will operate in dual mode with 512Mb of the second module, and the remaining 512MB from the 1GB module will operate in single-channel mode.

These are all recommendations for combining RAM. There may be more layout options, it all depends on the amount of RAM, the model of the motherboard and on your financial capabilities. Also on sale there are motherboards with support for four-channel memory operation - this will give you maximum computer performance!
Today, in modern personal computers, two types of RAM DDR 2 and DDR 3 are widely used. What type of RAM to choose?

It all depends on what your computer is intended for. If you are going to work in heavy programs and play sophisticated computer games, feel free to choose the type of DDR 3 - since this type of RAM often ranges from 800 MHz to 1600 MHz. Well, if you buy a regular office computer, take DDR 2. the frequency of this type varies from 400 to 800 MHz.

To the question of how much RAM to take, I will answer you like this. In modern computers (and even netbooks), the minimum amount of RAM is 4 gigabytes, which ensures high performance and normal working conditions. That is, when you want to install RAM (when buying a computer), take at least 4 GB and all programs (if you choose the other components correctly) will fly with you literally and figuratively (and you will not need to replace the RAM for a long time). We'll talk more about the location of the RAM in the point of installing RAM.

The location of the RAM. RAM compatibility
RAM is always located on the motherboard and is a small elongated rectangular plate that is inserted into special sections (slots) on the motherboard. The number of slots starts from two units, and maybe four or more. In the standard form, each motherboard has 4 slots, into which the RAM is installed. The figure shows four RAM slots, two of which contain memory modules.

RAM location

Typically, motherboard manufacturers give users the ability to use several of the same memory slots in order to avoid various errors in the PC. But, I warn you, if you buy several RAM slots, they must be of the same type (for example, DDR 3) and frequency.

Since the slots of different types of RAM will not work together, and if two chips have different frequencies, for example, one has 800 MHz and the other has 1600, then the memory will work at the minimum frequency and you may lose in the performance and speed of your PC. In the screenshot, different RAM slots differ in color and are divided into pairs, this is by no means a whim of the developers, but a very deliberate step.

Since many motherboards can operate in a dual-channel mode, in order to enable this mode, modules of the same frequency must be inserted into the memory slots of the same color, that is, the RAM must be installed in accordance with the color of the slot, in orange slot we put memory with a frequency of 800 MHz, and in violet with a frequency of 1600 MHz. Very often, this "play with colors" can increase the overall performance of the RAM by as much as 30 percent, which significantly affects the overall performance of the PC.

Installing RAM
And finally, I suggest you learn how to replace the RAM yourself. Replacing RAM is very simple and does not require any special skills.

In order to replace the RAM, you first need to disconnect your computer from the network, remove the system unit, if it is in a special section of your desktop, and open it carefully. Most often, the system blocks are screwed by hand with special bolts that can be easily unscrewed. It may also happen that you need a screwdriver. Anyway, after that. how you opened the system unit, you will see something like the following screenshot:

Installing RAM

I marked the operative memory in the picture. In order to remove the RAM module (for example, if you need to replace the RAM) from the slot, you need to slightly press on the side holders, after which the memory will come out of the slots and you can remove it.

If the situation is the opposite and you need to install RAM, for this we carefully insert the memory into the slots (taking into account its type and frequency) and click the locks until it clicks. Necessarily until you click, as this means that you have installed the RAM correctly.
