How much RAM do you have? How much RAM do you need for games?

Random Access Memory, commonly referred to as RAM or RAM, is one of the most important parts of any computer. But how much is needed for the device to work well? Current new PCs and similar devices offer values ​​from 2 GB to 16 GB or more.

The amount of memory required depends on two factors - what you intend to do and how much you are willing to spend.

Introduction to RAM

Memory capacity is often confused with the long-term storage offered by a solid state or mechanical hard drive. Sometimes even manufacturers or retailers confuse these concepts. To understand how much RAM needed for normal operation device, you need to figure out what its meaning is.

A table is a useful analogy to consider the difference between RAM and memory. Think of RAM as the top of the table. The larger its surface, the more papers you can spread out and read at once. Hard drives are more like drawers under your desk, capable of storing documents you don't use.

The larger your system, the more programs it can handle simultaneously. RAM is not the only determining factor, and you could technically have dozens of programs open at once with even very little RAM and it would slow down your system. Now imagine the table again. If it's too small, it becomes cluttered and your work will slow down as you try to find whatever paper you need at any given moment. You will often be forced to dig through drawers to place things that won't fit on the desk surface, as well as to get out the necessary papers.

A computer with more RAM runs noticeably faster, but only up to a certain point. Having a large desk won't help you if you only have a few articles to read.

Optimal ratio

How much RAM does your device need? Your goal is to have enough RAM for all the apps you use on that particular device. If there is too little of it, work slows down. Too much RAM can only mean that you've paid a lot of money for something you'll never be able to use.

Difference from other characteristics

Standard RAM should not be confused with video memory, but the two concepts are closely related to computer graphics cards. High-performance 3D games rely on video memory (VRAM), often expressed as GDDR5, while standard memory is called RAM or DDR3. In fact, most manufacturers are very good at identifying VRAM and not confusing it with other parameters. Therefore, to determine how much RAM is needed for GTA 5, for example, you need to consider both of the above indicators together.

Heavy Applications

The biggest services on most home computers are the operating system itself and the web browser. You can't make Windows or MacOS use less memory, but more RAM on your computer means you can open more tabs in Chrome, Firefox, Internet Explorer, etc. Plus, some websites use more RAM memory than others. Simple text news takes up almost no resources, while something like Gmail or Netflix requires a little more power.

Programs are generally used because they increase the complexity of the job. A chat program or game (like Minesweeper) will use almost no RAM, while a giant Excel spreadsheet or a huge Photoshop project might use more than one gigabyte. Professional and engineering software are built to handle very complex projects and tend to consume the majority of RAM of all programs. Modern 3D games can also use quite a lot of RAM and VRAM. In other words, your need for how much RAM to install depends on the programs you use.

• 2GB RAM: Good for tablets and netbooks only.
• 4 GB RAM: Minimum for budget Windows and MacOS systems.
• 8GB: Great for Windows and MacOS systems.
• 16 GB: Probably too much; Ideal for mid-range workstations.
• 32 GB or more: For enthusiasts and dedicated workstations only.

For tablet

Tablets are not expected to deal with complex tasks software, so their RAM needs tend to be quite low. However, as multi-tab browsers and more complex software continue to evolve, the needs of tablets are becoming more similar to those of laptops. Current specification options typically range from 2GB to 16GB of RAM, with processor speed playing a major role in determining the range.

For example, the iPad Air 2, which has about 2GB of RAM, places a lot of emphasis on its all-in-one processor. And a device like the Microsoft Surface Pro can accommodate up to 16GB of RAM because users of this device may want to run a lot of professional software as well as a desktop OS.

And it gives you guidelines for choosing RAM - what do you use your tablet for? If you only browse one site at a time and don't use the device for any large projects or work software, then 4GB RAM will probably be sufficient. However, if you also use your tablet as your main PC, you must equip it with the necessary RAM. Typically, this means you will need between 4 and 8 GB.

Choosing RAM for laptops

How much do you need? New laptops have between 2GB and 16GB of RAM, while high-end gaming models offer up to 32GB. As mentioned earlier, the needs of tablets and laptops converge, but most users feel comfortable running more complex programs on laptops, which means RAM plays a more important role here.

For something like a Chromebook, which runs primarily in the cloud and has very little storage space, you won't need much RAM. Opting for 4GB of RAM is enough, especially since you can use the Google Play Store to download Android applications right on your computer.

How much RAM is needed for Windows 10 and new MacBook modifications? You should consider increasing this number to the standard 8GB. Most of the best laptops come with this value for good reason. Of course, if you do a lot of graphical work or want to have multiple tabs open at once, you might want to consider upping the RAM to 16GB. This is especially true for gamers - the question of how much RAM is needed for games always remains relevant.

Desktop computers

RAM in desktop computers is cheap, so it's fairly easy to find PCs with more memory at lower prices. Additionally, more RAM on PCs can be beneficial as people tend to use them for longer periods of time than tablets or laptops.

How much RAM does a PC need? 8 GB is a good value to start with. Upgrading to 16GB is recommended for enthusiasts, hardcore gamers, and the average workstation user. Serious workstation users can upgrade to 32GB. Even when talking about how much RAM is needed for games, you can make sure that too significant parameters are not required.

Anything more is the edge of extreme specialties, equipped to handle huge amounts of data, huge video files or niche programs intended for researchers, corporations or government.

Please note that the amount of RAM and the type and speed supported by your system will depend on your motherboard.

How much RAM is there? - the question is not entirely correct, because the required quantity depends on many indicators - the available processor, motherboard and other components that make up a single integrated system.

In light of recent reviews on Chinese smartphones with RAM up to 6GB, which even now is not so common on modern computers, the question of expanding the capabilities of your machine naturally arises.

In this review, we will highlight all the nuances that will help you choose the right RAM for your computer.

Determining appetites

How much RAM is required?

1-2Gb. The required minimum for running office applications and viewing pages in a browser.

4Gb. A budget home version that allows you not only to work in a text editor and the Internet, but also to watch movies in high quality and work in a graphics editor.

8Gb. Advanced configuration - supports many modern games in basic settings, allows you to easily work with video files, test applications during programming, and much more.

Above 8Gb. Option for powerful PCs and laptops - allows you to run all modern games in high quality. The average user does not need this amount.

As you can see, there is no clear answer to the question “how much RAM do you need?” - it all depends on the operating mode you choose.

If you really don’t have enough RAM, we will tell you how to choose the right RAM.

More memory!

If you decide to increase the amount of RAM, carefully consider the parameters of your computer: Windows system configuration, type of RAM slots, processor clock speed and motherboard voltage. These parameters are displayed in the specific CPU Z program - all parameters and system components are displayed in one window.

1. Windows configuration. The system you are using also consumes some amount of RAM. If you have the WinXP version, adding modules is almost useless. 32-bit systems simply do not see more than 3 gigabytes. With later versions it is more difficult - starting from Win8.1 you will already need 8GB.
2. The type of RAM slots installed on your motherboard is an important aspect when choosing a module. It would be a shame to purchase the latest DDR4 and realize that motherboard does not support this type of plank, and categorically refuses to work with it. Any board supports only one type of RAM. If you have DDR2, then only DDR2 can be used and nothing else.
   Only the latest generation motherboards can support DDR4 memory, and if you really want to, you can take the opportunity and build a new computer.
3. CPU. Processor manufacturers take care of their users - on official websites there are usually compatibility tables with models and types of RAM sticks. For example, you can easily find the answer to which types are compatible and suitable for the Intel i5 processor - a list of models and configurations that it should support and that will keep the computer running like a clockwork, well-synchronized mechanism.

Market and assortment - the name matters

The main manufacturers of RAM modules in at the moment There are several leading companies:

• Corsair
• Crucial
• Samsung

When purchasing, you will overpay for the name, but at the same time you will receive a high-quality, proven product without unnecessary risks.

Types of RAM, fundamental differences

Today there are four generations of RAM. The most common modules are DDR2, DDR3, DDR3L and DDR4. So, how are RAM modules different?

DDR

The very first models of RAM. They were characterized by low performance (volume up to 512Mb and frequency up to 400MHz), high voltage (2.2 - 2.4V). Still used in very old computer models.

DDR2

The second generation, also gradually becoming a thing of the past. Motherboards that support this type of RAM sticks are no longer in production, as are the modules themselves. Compared to its predecessor, this type consumes an order of magnitude less energy (1.8-2.1V), and the frequency and volume have increased significantly: 800-1000 MHz and 1-8 GB, respectively. The number of contacts also increased from 184 to 240.

This is what a DDR2 bar looks like

DDR3

The most popular memory module today is DDR3, which is used by many modern cars. The frequency of the RAM module reaches 2800 MHz, but the number of timings in these types has also increased. But still, DDR3 has higher performance compared to its predecessors. There is also another type of this platform - DDR3L gives a more interesting energy saving indicator (1.35V compared to 1.5V in the basic configuration).

DDR4

If you decide to build a new computer, it is advisable to put it on a more modern platform with DDR4 RAM slots. With each generation of modules, the voltage decreases (for DDR4 this parameter has a value of 1.2V, which affects the overall power consumption of the computer), the frequency increases (this configuration has a maximum frequency of 4200 MHz) and data transfer speed. The latest generation of RAM operates at speeds of up to 3200Mbps, while for DDR3 the limit is 2133. At the moment, DDR4 has the most fast speed data transfer and maximum performance, while at the same time it practically does not heat up due to the low voltage requirement.

For comparison, one DDR4 2133 MHz CL 15 stick is enough to replace two new identical DDR3 2400 MHz sticks with the same amount of processor-related data transferred.

Types of RAM

RAM is a recording device designed to store and read data when a PC is running. RAM modules, differing in external and internal characteristics, are also classified according to other parameters.

RDIMM is register memory. This marking indicates that buffer registers are installed between the data bus and memory, which perform an additional function of monitoring data integrity.

LRDIMM is non-buffered memory. These are DIMM modules with reduced bus load due to an additional chip.

UDIMM is the type most commonly used in desktop and laptop computers. Unlike the previous two, it is less stable, since it is neither register nor buffered. However, on the scale of one PC this circumstance does not play a special role.

SODIMM is a compact option used in laptops and some types of office equipment. The fundamental difference is the form factor. The length of the SODIM bar is only 67.6 mm, while the other configurations measure 133.35 mm.

Main characteristics of RAM - what to look for

RAM voltage is a parameter that characterizes the RAM's need for electricity for normal, stable operation.

Many advanced users manually change the voltage supplied from the motherboard in the BIOS in order to increase performance. Without knowing some aspects, it is not recommended to perform this technique - you risk burning the module without achieving anything. Without knowledge of the BIOS, it is better not to touch it - the voltage will be set when installing the appropriate drivers. If you are in doubt, visit the manufacturer’s website and get parameters and recommendations for your type of device.

The frequency of RAM is an indicator on the value of which the data transfer speed directly depends. It is important to note that the operating frequency of the RAM stick must match or be less than the clock frequency of the motherboard. Otherwise, you will observe a sad result - the system will fail. Also, the optimized operation of the computer is facilitated by the ideal match of the data transfer speed between the processor and the RAM strip.

The main factor when choosing RAM is frequency, but you shouldn’t chase numbers. Clock frequency The strips should not exceed the processor frequency. The main mistake of users is that very often, in pursuit of hertz, they completely ignore this parameter. As a result, this nonsense threatens not only a bad mood, but also damage to the entire system as a whole.

RAM capacity is a characteristic that shows the amount of data that the module can hold. When choosing this indicator, you should focus on the type of activity you perform at the computer.

I hope this article was useful and you figured out whether it’s worth upgrading your RAM and how to do it correctly.

RAM is used to temporarily store data necessary for the operation of the operating system and all programs. There should be enough RAM; if there is not enough, the computer starts to slow down.

The board with memory chips is called a memory module (or stick). Memory for a laptop, except for the size of the slots, is no different from memory for a computer, so when choosing, follow the same recommendations.

For an office computer, one 4 GB DDR4 stick with a frequency of 2400 or 2666 MHz is enough (costs almost the same).
RAM Crucial CT4G4DFS824A

For a multimedia computer (movies, simple games), it is better to take two 4 GB DDR4 sticks with a frequency of 2666 MHz, then the memory will work in a faster dual-channel mode.
RAM Ballistix BLS2C4G4D240FSB

For a mid-class gaming computer, you can take one 8 GB DDR4 stick with a frequency of 2666 MHz so that in the future you can add another one, and it would be better if it is a simpler running model.
RAM Crucial CT8G4DFS824A

And for a powerful gaming or professional PC, you need to immediately take a set of 2 DDR4 8 GB sticks, and a frequency of 2666 MHz will be quite sufficient.

2. How much memory is needed

For an office computer designed for working with documents and accessing the Internet, one 4 GB memory stick is sufficient.

For a multimedia computer that can be used to watch high-quality videos and undemanding games, 8 GB of memory is sufficient.

For a mid-range gaming computer, the minimum option is 8 GB of RAM.

A powerful gaming or professional computer requires 16 GB of memory.

A larger amount of memory may be needed only for very demanding professional programs and is not needed by ordinary users.

Memory capacity for older PCs

If you decide to increase the amount of memory on your old computer, keep in mind that 32-bit Windows versions Does not support more than 3 GB of RAM. That is, if you install 4 GB of RAM, the operating system will see and use only 3 GB.

As for 64-bit versions of Windows, they will be able to use all the installed memory, but if you have an old computer or an old printer, then they may not have drivers for these operating systems. In this case, before purchasing memory, install the 64-bit version of Windows and check if everything works for you. I also recommend looking at the website of the motherboard manufacturer and seeing what volume of modules and total memory it supports.

Please also note that 64-bit operating systems consume 2 times more memory, for example, Windows 7 x64 takes about 800 MB for its needs. Therefore, 2 GB of memory for such a system will not be enough, preferably at least 4 GB.

Practice shows that modern operating systems Windows 7,8,10 are fully operational with a memory capacity of 8 GB. The system becomes more responsive, programs open faster, and jerks (freezes) disappear in games.

3. Memory types

Modern memory is of the DDR SDRAM type and is constantly being improved. So DDR and DDR2 memory is already obsolete and can only be used on older computers. DDR3 memory is no longer advisable to use on new PCs; it has been replaced by the faster and more promising DDR4.

Please note that the selected memory type must be supported by the processor and motherboard.

Also, new processors, for compatibility reasons, can support DDR3L memory, which differs from regular DDR3 in reduced voltage from 1.5 to 1.35 V. Such processors will be able to work with regular DDR3 memory if you already have it, but processor manufacturers do not recommend this because -due to increased degradation of memory controllers designed for DDR4 with an even lower voltage of 1.2 V.

Memory type for older PCs

Outdated DDR2 memory costs several times more than more modern memory. A 2 GB DDR2 stick costs 2 times more, and a 4 GB DDR2 stick costs 4 times more than a DDR3 or DDR4 stick of the same size.

Therefore, if you want to significantly increase the memory on an old computer, then perhaps the best option would be to switch to a more modern platform by replacing the motherboard and, if necessary, a processor that will support DDR4 memory.

Calculate how much it will cost you; perhaps a profitable solution would be to sell the old motherboard with old memory and purchase new, albeit not the most expensive, but more modern components.

The motherboard connectors for installing memory are called slots.

Each memory type (DDR, DDR2, DDR3, DDR4) has its own slot. DDR3 memory can only be installed in a motherboard with DDR3 slots, DDR4 - with DDR4 slots. Motherboards that support old DDR2 memory are no longer produced.

5. Memory characteristics

The main characteristics of memory on which its performance depends are frequency and timings. Memory speed does not have as strong an impact on overall computer performance as the processor. However, you can often get faster memory for not much more. Fast memory is needed primarily for powerful professional computers.

5.1. Memory frequency

Frequency has highest value on memory speed. But before purchasing it, you need to make sure that the processor and motherboard also support the required frequency. Otherwise, the actual memory operating frequency will be lower and you will simply overpay for something that will not be used.

Inexpensive motherboards support lower maximum memory frequencies, for example for DDR4 it is 2400 MHz. Mid-range and high-end motherboards can support higher frequency memory (3400-3600 MHz).

But with processors the situation is different. Older processors with DDR3 memory support may support memory with a maximum frequency of 1333, 1600, or 1866 MHz (depending on the model). For modern processors that support DDR4 memory, the maximum supported memory frequency may be 2400 MHz or higher.

Intel 6th generation and higher processors and AMD Ryzen processors support DDR4 memory at 2400 MHz or higher. At the same time, in their model range There are not only powerful expensive processors, but also mid- and budget-class processors. Thus, you can build a computer on the most modern platform with an inexpensive processor and DDR4 memory, and in the future change the processor and get the highest performance.

The main memory today is DDR4 2400 MHz, which is supported by the most modern processors, motherboards and costs the same as DDR4 2133 MHz. Therefore, purchasing DDR4 memory with a frequency of 2133 MHz today does not make sense.

You can find out what memory frequency a particular processor supports on the manufacturers’ websites:

By model number or serial number it is very easy to find all the characteristics of any processor on the website:

Or simply enter your model number in search engine Google or Yandex (for example, “Ryzen 7 1800X”).

5.2. High Frequency Memory

Now I want to touch on another interesting point. On sale you can find RAM at a much higher frequency than any modern processor supports (3000-3600 MHz and higher). Accordingly, many users are wondering how this can happen?

It's all about a technology developed by Intel, eXtreme Memory Profile (XMP). XMP allows memory to run at a higher frequency than the processor officially supports. XMP must be supported by both the memory itself and the motherboard. High-frequency memory simply cannot exist without support for this technology, but not all motherboards can boast of its support. These are mainly more expensive models above the middle class.

The essence of XMP technology is that the motherboard automatically increases the frequency of the memory bus, due to which the memory begins to operate at its higher frequency.

AMD has a similar technology called AMD Memory Profile (AMP), which was supported by older AMD processor motherboards. These motherboards usually also supported XMP modules.

Purchasing more expensive memory with a very high frequency and a motherboard with XMP support makes sense for very powerful professional computers equipped with a top-end processor. In a middle-class computer, this will be wasted money, since everything will depend on the performance of other components.

In games, the memory frequency has a small impact and there is no point in overpaying; it will be enough to go for 2400 MHz, or 2666 MHz if the difference in price is small.

For professional applications, you can take memory with a higher frequency - 2666 MHz or, if you want and have funds, 3000 MHz. The difference in performance here is greater than in games, but not dramatic, so there is no particular point in pushing the memory frequency.

Let me remind you once again that your motherboard must support memory at the required frequency. In addition, sometimes Intel processors become unstable at memory frequencies above 3000 MHz, and for Ryzen this limit is around 2900 MHz.

Timings are the delays between read/write/copy operations of data in RAM. Accordingly, the fewer these delays, the better. But timings have a much smaller impact on memory speed than its frequency.

There are only 4 main timings that are indicated in the characteristics of memory modules.

Of these, the most important is the first number, which is called latency (CL).

Typical latency for DDR3 1333 MHz memory is CL 9, for higher frequency DDR3 memory is CL 11.

Typical latency for DDR4 2133 MHz memory is CL 15, for DDR4 memory with higher frequencies is CL 16.

You should not purchase memory with a latency higher than specified, as this indicates an overall low level of its technical characteristics.

Typically, memory with lower timings is more expensive, but if the price difference is not significant, then memory with lower latency should be preferred.

5.4. Supply voltage

Memory may have different supply voltages. It can be either standard (generally accepted for a certain type of memory), or increased (for enthusiasts) or, conversely, reduced.

This is especially important if you want to add memory to your computer or laptop. In this case, the voltage of the new strips should be the same as the existing ones. Otherwise, problems are possible, since most motherboards cannot set different voltages for different modules.

If the voltage is set to a level with a lower voltage, then others may not have enough power and the system will not work stably. If the voltage is set to a level with a higher voltage, then the memory designed for a lower voltage may fail.

If you are building a new computer, then this is not so important, but to avoid possible problems compatibility with motherboard and replacing or expanding memory in the future, it is better to choose sticks with a standard supply voltage.

The memory, depending on the type, has the following standard supply voltages:

• DDR - 2.5 V
• DDR2 - 1.8 V
• DDR3 - 1.5 V
• DDR3L - 1.35 V
• DDR4 - 1.2 V

I think you noticed that there is DDR3L memory in the list. This is not a new type of memory, but regular DDR3, but with a reduced supply voltage (Low). This is the kind of memory needed for Intel processors 6th generation and above, which support both DDR4 and DDR3 memory. But in this case, it is better to build the system on new DDR4 memory.

6. Marking of memory modules

Memory modules are marked depending on the type of memory and its frequency. The marking of DDR memory modules begins with PC, followed by a number indicating the generation and speed in megabytes per second (MB/s).

Such markings are inconvenient to navigate; it is enough to know the type of memory (DDR, DDR2, DDR3, DDR4), its frequency and latency. But sometimes, for example on ad sites, you can see markings copied from the strip. Therefore, so that you can get your bearings in this case, I will give the markings in a classic form, indicating the type of memory, its frequency and typical latency.

DDR - obsolete

• PC-2100 (DDR 266 MHz) - CL 2.5
• PC-2700 (DDR 333 MHz) - CL 2.5
• PC-3200 (DDR 400 MHz) - CL 2.5

DDR2 - obsolete

• PC2-4200 (DDR2 533 MHz) - CL 5
• PC2-5300 (DDR2 667 MHz) - CL 5
• PC2-6400 (DDR2 800 MHz) - CL 5
• PC2-8500 (DDR2 1066 MHz) - CL 5

DDR3 - obsolete

• PC3-10600 (DDR3 1333 MHz) - CL 9
• PC3-12800 (DDR3 1600 MHz) - CL 11
• PC3-14400 (DDR3 1866 MHz) - CL 11
• PC3-16000 (DDR3 2000 MHz) - CL 11

• PC4-17000 (DDR4 2133 MHz) - CL 15
• PC4-19200 (DDR4 2400 MHz) - CL 16
• PC4-21300 (DDR4 2666 MHz) - CL 16
• PC4-24000 (DDR4 3000 MHz) - CL 16
• PC4-25600 (DDR4 3200 MHz) - CL 16

DDR3 and DDR4 memory may have a higher frequency, but only top processors and more expensive motherboards can work with it.

7. Design of memory modules

Memory sticks can be single-sided, double-sided, with or without radiators.

7.1. Chip placement

Chips on memory modules can be placed on one side of the board (single-sided) or on both sides (double-sided).

This doesn't matter if you are purchasing memory for a new computer. If you want to add memory to an old PC, then it is advisable that the arrangement of chips on the new stick be the same as on the old one. This will help avoid compatibility issues and increase the likelihood of memory operating in dual-channel mode, which we will talk about later in this article.

Now on sale you can find many memory modules with aluminum radiators of various colors and shapes.

The presence of heatsinks can be justified on DDR3 memory with a high frequency (1866 MHz or more), since it heats up more. At the same time, ventilation must be well organized in the housing.

Modern DDR4 RAM with a frequency of 2400, 2666 MHz practically does not heat up and the radiators on it will be purely decorative. They can even get in the way, because after a while they become clogged with dust, which is difficult to clean out of them. In addition, such memory will cost somewhat more. So, if you want, you can save on this, for example, by taking excellent Crucial 2400 MHz memory without heatsinks.

Memory with a frequency of 3000 MHz or more also has an increased supply voltage, but it also does not heat up very much and in any case there will be heatsinks on it.

8. Memory for laptops

Memory for laptops differs from memory for desktop computers only in the size of the memory module and is labeled SO-DIMM DDR. Just like for desktop computers, memory for laptops has types DDR, DDR2, DDR3, DDR3L, DDR4.

In terms of frequency, timings and supply voltage, memory for laptops is no different from memory for computers. But laptops only come with 1 or 2 memory slots and have stricter maximum capacity limits. Be sure to check these parameters before choosing memory for a specific laptop model.

9. Memory operating modes

The memory can operate in Single Channel, Dual Channel, Triple Channel or Quad Channel mode.

In single-channel mode, data is written sequentially to each module. In multi-channel modes, data is written in parallel to all modules, which leads to a significant increase in the speed of the memory subsystem.

Single-channel memory mode is limited only to hopelessly outdated motherboards with DDR memory and the first models with DDR2.

All modern motherboards support dual-channel memory mode, while three-channel and quad-channel modes are supported only by a few models of very expensive motherboards.

The main condition for dual-channel mode operation is the presence of 2 or 4 memory sticks. Three-channel mode requires 3 or 6 memory sticks, and four-channel mode requires 4 or 8 memory sticks.

It is desirable that all memory modules are the same. Otherwise, dual-channel operation is not guaranteed.

If you want to add memory to an old computer and your motherboard supports dual-channel mode, try to choose a stick that is as identical in all respects as possible. It is best to sell the old one and buy 2 new identical strips.

In modern computers, memory controllers have been moved from the motherboard to the processor. Now it is not so important that the memory modules are the same, since the processor will still be able to activate dual-channel mode in most cases. This means that if you want to add more memory in the future modern computer, then you won’t have to look for exactly the same module; it’s enough to choose the one with the most similar characteristics. But I still recommend that the memory modules be the same. This will give you a guarantee of its fast and stable operation.

With the transfer of memory controllers to the processor, 2 more modes of dual-channel memory operation appeared - Ganged (paired) and Unganged (unpaired). If the memory modules are the same, the processor can work with them in Ganged mode, as before. If the modules differ in characteristics, the processor can activate the Unganged mode to eliminate distortions in working with memory. In general, the memory speed in these modes is almost the same and makes no difference.

The only downside to dual-channel mode is that multiple memory modules are more expensive than one of the same size. But if you are not very strapped for money, then buy 2 sticks, the memory speed will be much higher.

If you need, say, 16 GB of RAM, but you can’t afford it yet, then you can purchase one 8 GB stick so that you can add another one of the same kind in the future. But it is still better to purchase two identical strips at once, since later you may not be able to find the same one and you will encounter a compatibility problem.

10. Memory module manufacturers

One of the best price/quality ratios today comes from the memory of the impeccably proven Crucial brand, which has modules from budget to gaming (Ballistix).

Competing with it is the well-deserved Corsair brand, whose memory is somewhat more expensive.

As an inexpensive but high-quality alternative, I especially recommend the Polish brand Goodram, which has bars with low timings at a low price (Play line).

For an inexpensive office computer, simple and reliable memory made by AMD or Transcend will be sufficient. They have proven themselves to be excellent and there are practically no problems with them.

In general, the Korean companies Hynix and Samsung are considered leaders in memory production. But now modules of these brands are mass-produced in cheap Chinese factories, and among them there are a lot of fakes. Therefore, I do not recommend purchasing memory from these brands.

An exception may be Hynix Original and Samsung Original memory modules, which are manufactured in Korea. These strips are usually blue, their quality is considered better than those made in China and the guarantee for them is slightly higher. But in terms of speed characteristics, they are inferior to memory with lower timings from other quality brands.

Well, for enthusiasts and fans of modding there are affordable overclocking brands GeIL, G.Skill, Team. Their memory is distinguished by low timings, high overclocking potential, unusual appearance and costs a little less than the well-promoted Corsair brand.

There is also a large assortment of memory modules on sale from the very popular manufacturer Kingston. Memory sold under the budget Kingston brand has never been of high quality. But they have a top-end HyperX series, which is deservedly popular, which can be recommended for purchase, but is often overpriced.

11. Memory packaging

It is better to purchase memory in individual packaging.

It is usually of higher quality and is much less likely to be damaged in transit than memory that comes loose.

12. Increase memory

If you are planning to add memory to an existing computer or laptop, then first find out what the maximum memory capacity and total memory capacity is supported by your motherboard or laptop.

Also check how many memory slots are on the motherboard or laptop, how many of them are occupied and what kind of memory sticks are installed in them. It's better to do it visually. Open the case, take out the memory sticks, examine them and write down all the characteristics (or take a photo).

If for some reason you don’t want to get into the case, you can view the memory parameters in the program on the SPD tab. This way you won't know if the stick is single-sided or double-sided, but you can find out the memory characteristics if there is no sticker on the stick.

There is a base and effective memory frequency. The CPU-Z program and many similar ones show the base frequency, it must be multiplied by 2.

Once you know how much memory you can increase, how many free slots are available, and what kind of memory you have installed, you can begin to explore the possibilities of increasing memory.

If all memory slots are occupied, then the only way to increase memory is to replace existing memory sticks with new ones of larger capacity. And old planks can be sold on an advertisement site or exchanged at a computer store when purchasing new ones.

If there are free slots, then you can add new memory sticks to the existing ones. In this case, it is desirable that the new strips be as close as possible to the characteristics of those already installed. In this case, you can avoid various compatibility problems and increase the chances that the memory will work in dual-channel mode. To do this, the following conditions must be met, in order of importance.

1. The memory type must match (DDR, DDR2, DDR3, DDR3L, DDR4).
2. The supply voltage for all strips must be the same.
3. All planks must be single-sided or double-sided.
4. The frequency of all bars must match.
5. All strips must be of the same volume (for dual-channel mode).
6. The number of strips must be even: 2, 4 (for dual-channel mode).
7. It is desirable that the latency (CL) matches.
8. It is desirable that the strips are from the same manufacturer.

The easiest place to start choosing is with the manufacturer. In the online store catalog, choose strips of the same manufacturer, volume and frequency as those installed in yours. Make sure that the supply voltage matches and check with your consultant whether they are single-sided or double-sided. If the latency also matches, then generally good.

If you were unable to find strips from the same manufacturer with similar characteristics, then choose all the others from the list of recommended ones. Then again look for strips of the required volume and frequency, check the supply voltage and check whether they are single-sided or double-sided. If you are unable to find similar planks, then look in another store, catalog or ad site.

Always best option This means selling all the old memory and buying 2 new identical sticks. If the motherboard does not support the brackets of the required volume, you may have to buy 4 identical brackets.

13. Setting up filters in the online store

1. Go to the “RAM” section on the seller’s website.
2. Select recommended manufacturers.
3. Select the form factor (DIMM - PC, SO-DIMM - laptop).
4. Select the memory type (DDR3, DDR3L, DDR4).
5. Select the required volume of slats (2, 4, 8 GB).
6. Select the maximum frequency supported by the processor (1600, 1866, 2133, 2400 MHz).
7. If your motherboard supports XMP, add higher frequency memory (2666, 3000 MHz) to the selection.
8. Sort the selection by price.
9. Consistently review all items, starting with the cheapest ones.
10. Select several strips that match the frequency.
11. If the price difference is acceptable to you, take sticks with a higher frequency and lower latency (CL).

Thus, you will get the optimal price/quality/speed ratio of memory at the lowest possible cost.

Today it is the most acute problem. Almost all users refuse 32-bit operating systems, while they absolutely do not understand why they need 64-bit operating systems. As a rule, the answer is standard: “I have a 64-bit processor, so the operating system is 64-bit.” Fortunately, the development of 64-bit operating systems and applications has led to the fact that we practically do not notice what environment we are working in, unless it becomes necessary to connect some old printer or scanner to the computer, the manufacturer of which did not bother to release a 64-bit driver.
The history of the development of requirements for the amount of RAM in a personal computer is such that in 1981 Bill Gates said that 640 kilobytes of computer RAM was enough for everything. Indeed, it is enough to recall the times of the dominance of the DOS operating system, in particular MS-DOS, when 4 megabytes of RAM was enough, and 8-12 megabytes was enough to run almost any gaming application. It should be understood that the DOS kernel itself is 16-bit and in order to use all 4 or 8-12 megabytes of RAM it was necessary to ensure the loading of special DPMI (DOS Protected Mode Interface) drivers, which allowed 32-bit applications to use the entire amount of RAM.

The appearance of the first versions of Windows from Microsoft - the Windows shell for workgroups, full-fledged operating systems Windows 95, Windows 98, Windows Vista, Windows XP - did not foretell a move beyond the 32-bit standard. It seemed that three gigabytes of RAM would be quite enough for home use. But the software developed, made increasing demands on the amount of RAM, and AMD began to integrate 64-bit instructions and RAM controllers into its AMD Athlon 64 XP processors - the best processors of its time.

Previously, there was a heated discussion about which application works faster - 32-bit or 64-bit. Experience has shown that if you have less than or exactly 3 gigabytes of RAM - there is practically no point in switching to a 64-bit system - a slight increase will be noticeable in some applications, and a slight drop in others. Full compatibility 64-bit operating systems with 32-bit ones do not impose strict restrictions on software manufacturers, so they try to create 32-bit applications, and if the application actively uses RAM, then 64-bit.

Fortunately, Microsoft realized its mistakes and created a completely new operating system - Windows 7. In this case, the 32-bit and 64-bit versions of the Windows 7 Ultimate operating systems each support 4 gigabytes and 192 gigabytes of RAM, that is, the entire allowable amount of within binary calculus formats. Stripped down versions of Windows 7 support smaller amounts of memory. For example, Windows 7 Starter x32 installed on netbooks and some laptops supports only 2 gigabytes of memory, while versions of Windows 7 Home Basic x64 and Windows 7 Home Premium x64 support 8 and 16 gigabytes, respectively. Naturally, all these restrictions were created artificially by Microsoft in order to make different operating systems from one product, both in functionality and cost.

For home users, we recommend, depending on budget limitations, to take a closer look at 4 and 8 gigabyte DDR3 memory sticks. If your budget is limited, buy 4 gigabyte strips; if your budget allows, then buy 8 gigabyte strips. In this case, you should remember the rules that we described in our previous materials.

The main thing for a new computer is to purchase the same memory sticks, and their number should correspond to the channel of the processor memory controller. Most modern processors have dual-channel memory controllers. Therefore, buying two 4 gigabyte sticks will allow you to get 8 gigabytes of total memory, which is enough for modern games on a computer with one monitor. And if you purchase two 8 gigabyte sticks, you will get a total of 16, which is enough for a computer with multiple monitors. Conclusion
In any case, when deciding on the amount of RAM, we recommend not to forget about the balance of your personal computer. By assembling a gaming computer for home with 16 gigabytes of memory and a weak video card, you will get the same performance as with 4 gigabytes of RAM. For an office computer, we recommend not saving on a penny of memory, since intensive data exchange and work on the Internet leads to massive use of RAM due to caching - here an additional 1-2 gigabytes of memory can significantly reduce the intensity of using the hard drive for uploading data to swap file.

Good afternoon.

Today's article is devoted to RAM, or more precisely its quantity on our computers (RAM is often abbreviated as RAM). RAM plays a big role in the operation of the computer; if there is not enough memory, the PC begins to slow down, games and applications open reluctantly, the picture on the monitor begins to “twitch”, the load on the computer increases. hard drive. In the article we will focus on issues related to memory: its types, how much memory is needed, what it affects.

How to find out the amount of RAM?

1) The easiest way to do this is to go to “my computer” and right-click anywhere in the window. Next select in context menu conductor of "properties". You can also open the control panel and enter “system” in the search bar. See screenshot below.

The amount of RAM is indicated next to the performance index, under the processor information.

4GB- amount of RAM. The more, the better. But do not forget that if the processor in the system is not so powerful, then there is no point in installing a large amount of RAM. In general, sticks can be of completely different sizes: from 1GB to 32 or more. See below for volume.

1600Mhz PC3-12800- Operating frequency (bandwidth). This table will help you understand this indicator:

As can be seen from the table, the throughput of such RAM is 12800 MB/s. Not the fastest today, but as practice shows, the amount of memory is much more important for the speed of a computer.

The amount of RAM on the computer

1 GB - 2 GB

Today, this amount of RAM can only be used on office computers: for editing documents, browsing the Internet, and mail. It is, of course, possible to run games with this amount of RAM, but only the simplest ones.

By the way, with this volume you can install Windows 7, it will work fine. True, if you open five documents, the system may begin to “think”: it will not react so sharply and zealously to your commands, the picture on the screen may begin to “twitch” (especially for games).

Also, if there is a lack of RAM, the computer will use: part of the information from RAM, which is not currently in use, will be written to the hard drive, and then, as necessary, read from it. Obviously, in this state of affairs there will be an increased load on the hard drive, and this can also greatly affect the speed of the user’s work.

4 GB

The most popular amount of RAM lately. Many modern PCs and laptops running Windows 7/8 have 4 GB of memory. This volume is enough for normal work with office applications, it will allow you to run almost all modern games (even if not at maximum settings), and watch HD video.

8 GB

This amount of memory is becoming more and more popular every day. It allows you to open dozens of applications, while the computer behaves very quickly. In addition, with this amount of memory you can run many modern games at high settings.

However, it is worth noting immediately. That this amount of memory will be justified if you have a powerful processor installed in your system: Core i7 or Phenom II X4. Then he will be able to use the memory to its full potential - and there will be no need to use the swap file at all, thereby increasing the speed of operation significantly. In addition, the load on the hard drive is reduced and energy consumption is reduced (relevant for a laptop).

By the way, the opposite rule also applies here: if you have a budget processor, then there is no point in installing 8 GB of memory. The processor will simply process a certain amount of RAM, say 3-4 GB, and the rest of the memory will add absolutely no speed to your computer.
