Then it will not be possible to replace it with a newer and more advanced DDR4 - along with the memory, you will have to change the motherboard and processor. When assembling a new computer, the most current type of memory at the moment is recommended - DDR4.
Memory
It is recommended to install at least 4 GB in a modern computer random access memory. The standard now is 8 GB - this amount is enough for the user for most everyday tasks. A professional who often works in "heavy" programs, such as Autocad and 3DSMax, is recommended to install modules of 16 GB and higher.
Memory is often sold in sets of two , four or more modules . Two modules with the same parameters inserted into slots of the same color motherboard, will work in "dual-channel mode" - this will give an increase in data transfer speed and increase the speed of the system and applications.
Clock frequency
The clock frequency of the memory determines the speed of data exchange with the motherboard. The higher the frequency, the faster the computer runs. The memory bandwidth and the price of the module directly depend on it. You need to choose memory based on what frequencies are supported by the motherboard and processor.
Form factor
Most home computers use the DIMM form factor. Laptops most often have SODIMM memory installed. Other form factors are unlikely to be of interest. simple user- they are installed either on servers or on older PCs.

A computer is a versatile device on which you can perform a huge number of tasks. Some users use its features for studying, others prefer to watch movies on PC, and still others require powerful "machines" for games and professional activity. In each of these cases, you need to know how to choose the right RAM for a personal computer or laptop.
The performance and speed of the assembled system largely depends on this component. In this article, we will figure out which memory is better to buy depending on your needs and what you should pay attention to in the first place.
Budget and memory requirements
The memory on the market for a computer or laptop varies greatly in cost. A huge number of parameters affect the price of the trims, including additional features such as heatsinks or customizable RGB lighting. As for the requirements, they depend on whether you are building a new system or upgrading an existing one. For example, if you decide to add RAM to a computer or laptop, you will need to select brackets whose characteristics correspond to the parameters of the RAM installed in the PC. Experts often recommend even choosing the same manufacturer, but it is not necessary to follow this rule.
Criteria for choosing RAM
When planning to add memory to an existing PC or wanting to purchase RAM for a new computer, you will definitely come across a number of important criteria. Among them, the most important are frequency and timings. Also, the system performance is affected by the volume and number of slats included in the kit. Additional RAM capabilities usually do not bring practical benefits to the average user. So the backlight will be appropriate mainly for gaming PCs, where a similar feature is implemented in other components. Radiators, which were also mentioned above, may be required only for high-frequency RAM and compact assemblies, where there may be problems with high-quality ventilation of the case.
Memory types
Usually it is necessary to select the memory for the motherboard. There are 4 of them in total: outdated DDR and DDR2, which still retains the popularity of DDR3, capable of operating at frequencies up to 2400 MHz, as well as the most modern DDR4, the theoretical maximum of which is 4266 MHz.
Despite the fact that some stores still have stocks of DDR2 strips, it is almost impossible to find a motherboard for this type of RAM on sale. Only used versions of such boards are presented on the market, and new devices have not been produced by manufacturers for a long time.
For the remaining two types of motherboards are offered in a wide range. But for a gaming computer, it is better to choose DDR4 RAM, because the new Ryzen processors from AMD and Coffee Lake from Intel, capable of fully unleash the potential of modern designs that no longer support DDR3.
However, you will not be able to install the wrong RAM into your computer, because they are incompatible with each other due to the different number and arrangement of contacts. For this reason, a board with slots for DDR4 brackets does not support DDR3, and vice versa.
The exceptions are motherboards, where it is possible to install both DDR3 and DDR4 memory at the same time. However, such solutions are rare and there is no point in buying them, because both types of strips differ only slightly in price when DDR4 surpasses its predecessor by several times in terms of parameters.
When buying memory for an office computer, you can stop at the DDR3 type. If you are building a powerful gaming PC, then purchase DDR4 brackets to avoid frame drops.
Volume
Deciding how much memory to choose should be based on the tasks that will be performed on the computer. So office systems aimed at working with text and surfing the Internet, it is enough to equip 2-4 GB. Volume from 4 to 8 GB must be installed already in multimedia and basic computers for games. But powerful gaming machines should be equipped with 16-32 GB of RAM. This amount of RAM is now enough for any modern project.
If you plan to take a larger amount of RAM for your computer, then this will be justified in two cases: a reserve for the future or specialized tasks. It is likely that in 2-3 years there will be games that will require 24 or more RAM to run stably at high graphics settings. If during this or a longer period you do not update the PC, then you can immediately take the appropriate strips. Also, 32 or more gigabytes of RAM will be required for the operation of professional programs.
You also need to take into account the bit depth and version of the system that is installed on your computer. So 32-bit Windows will not see more than 4 GB of RAM, and if we are talking about Windows 7 Starter, then it can only work with 2 gigabytes. At the same time, 64-bit operating systems use about twice as much RAM for their needs, which also needs to be taken into account when assembling the system.
The maximum version of Windows 7 can run with 192 gigabytes of RAM, and professional Windows versions 8 and 10 already support up to 512 GB. You can find out the exact information about the amount of RAM that can be installed in your system on the official Microsoft website.
If you install more memory into the computer than the operating system installed on it supports, then the “extra” amount will simply not be used.
What frequency to choose
As in the case of processors or graphics adapters, the frequency of RAM determines its performance. The higher this figure, the better performance the PC will show. However, you should not immediately run after the most advanced RAM that is only in the store. Before buying, you need to make sure that the selected option is supported by the motherboard and processor.
Of course, if you get better memory performance than what your hardware can reveal, then there will be nothing wrong with that. When you install such strips in your computer, they will simply start working at the maximum frequency supported by the system. But the disadvantage in this case there will be higher costs, because a good 3000 MHz RAM will cost more than its counterpart from the same series at 2400 MHz.
Again, look for bars whose frequency matches maximum values supported by your computer is also not worth it. For office tasks, simple models at 1333 MHz (DDR3) or 2133 MHz (DDR4) will suffice. Balanced solution for a wide range tasks will be RAM with a frequency of 2400 or 2666 MHz. But progressive gaming PCs and professional assemblies are already better equipped with RAM at 3000-3600 MHz or more.
Developed by Intel, XMP technology and its counterpart from AMD called AMP allow high-frequency RAM to work at its maximum capabilities even if the declared frequency is not supported by the processor. However, this technology must be implemented not only in the "stone" itself, but also in the motherboard, which automatically raises its price.
Timings
This parameter in the characteristics is indicated by a number-alphabetic (for example, CL15) or numerical (15-17-17-35) designation. Both in the first and in the second case we are talking about the delay of the RAM between the execution of various operations. If you want to choose the right RAM, then this parameter must be paid attention to Special attention, because at high timings and high frequency, you will get about the same performance as in low-frequency RAM with small delays.
For the DDR3 type, CL9 will be excellent timings, and in slower models that are popular on the market, this parameter is equal to CL11. Standard delays in DDR4 strips are CL15, and in cheaper memory modules you can see CL16 or CL17 timings. For this type of RAM, you can find smaller delays, but they are extremely rare on sale.
Note. The designation CL corresponds to the first number in the block of digits. So the above numerical designation of timings 15-17-17-35 can be written as CL15.
Important! Buying RAM with high timings is not recommended. According to reviews of such memory on the forums, you can understand that it has poor performance and significantly worsens the performance of the PC.
Operating modes
Many users forget that not only the choice of the amount of RAM is important, but also the number of slats from which it is typed. This is due to the fact that in modern computers RAM operates in multi-channel mode, which significantly improves system performance in professional applications, demanding games and other tasks. When installing a single 16 GB memory module into a computer or laptop, you will get worse performance than when choosing a pair of 8 GB sticks.
In total, 4 modes of RAM operation are allocated today:
- Single channel.
- Dual channel.
- Three-channel.
- Four-channel.
The first is considered obsolete and is only present in older PCs. Its essence lies in the fact that all data is written sequentially to each module, regardless of their total number. Modern computers can work in this mode if the user has installed only one bar of RAM.
Most motherboards released in recent years work in dual-channel mode. However, boards with support for three- and four-channel configurations are also on sale. However, the cost of such models is quite high, and the advantage of the indicated modes can not always be seen.
In this case, it should be borne in mind that the dual-channel mode works when using 2 or 4 memory bars, the three-channel mode - 3 or 6, and the four-channel mode - 4 or 8. Another important nuance is the need to install modules with the same volume, frequency, timings and other parameters.
However, if the characteristics of the bars do not match, then this will not affect the performance (with the exception of voltage). At different frequencies the system will be able to operate at the frequency of the slowest module. A similar rule applies to timings. If the volumes do not match in the PC, the multi-channel mode will simply not work.
Separately, it is also worth noting the Flex option. It allows you to deviate from the specified rule and use memory strips of different sizes for dual-channel mode. In this case, the matching volumes will be used in dual-channel mode, and the remaining one will be used in single-channel mode. For example, when choosing modules for 8 and 4 GB, 4 GB from each bar will work in dual-channel mode, when the remaining 4 GB from the first module can operate in single-channel mode.
When buying, you need to take into account that one RAM module will cost a little cheaper than a set of brackets with similar parameters and the same total volume. However, the purchase of all the strips separately from each other will cost you significantly a large amount. Therefore, if you have enough budget, it is better to immediately purchase a set of the required volume.
Important! Flex Mode is not supported by all motherboards, so you should read the instructions for your board before selecting RAM for expansion.
Form factor
Also from the characteristics of memory modules for users, the form factor is important. It happens DIMM or SO-DIMM. The first are standard PC brackets, which, depending on the type, can contain from 168 to 240 pins. The SO-DIMM form factor refers to memory for laptops or small computers with Mini-ITX motherboards. On such strips there are from 72 to 200 contacts.
Supply voltage
This characteristic is especially important when choosing an additional memory bar for a PC or laptop. Despite the fact that most modern planks work on standard voltage(2.5V for DDR, 1.8V for DDR2, 1.5V for DDR3, 1.2V for DDR4), solutions for enthusiasts with increased nutrition and lower models. It is strictly forbidden to install bars that are incompatible with this parameter in a PC, because unstable operation of RAM is possible (if the bar does not receive enough voltage) or even its failure (when a higher power is supplied to the RAM than it needs to work).
Before buying an additional RAM module for your computer, first of all, make sure that the power it requires matches the voltage of the RAM installed in your PC.
Deciphering the marking of RAM
For labeling bars of any type, standard designations are used, including the letters PC and a number indicating the transfer rate in Mb / s (bandwidth). But it is not very convenient for an ordinary user to navigate through them, because it is much more convenient to know the frequency and timings.
Usually the seller indicates all the information about the memory, but if you pick up a used RAM on an ad site, then an inexperienced user may well indicate something like a PC2-8500. This means that we have DDR2 RAM with a frequency of 1066 MHz and CL5 timings.
DDR3 sticks are designated PC3:
- 10600 - 1333 MHz;
- 12800 - 1600 MHz;
- 14400 - 1866 MHz;
- 16000 - 2000 MHz.
In the first case, the timings are CL9, and in the other three, CL11.
DDR4 strips are marked, respectively, PC4:
- 17000 - 2133 MHz;
- 19200 - 2400 MHz;
- 21300 - 2666 MHz;
- 24000 - 3000 MHz;
- 25600 - 3200 MHz.
For the first type of memory, the latency is usually CL15, and for the others - CL16.
What brand of RAM modules to buy
Speaking about which RAM to choose, it is also necessary to mention its manufacturers. This market has its own undisputed leaders with rich experience and factories equipped with last word technology. Well-known brands guarantee that the strips you purchase can last without breakdowns and failures. long years. If you want to get high quality RAM and have a sufficient amount of funds, then you should take a closer look at the following popular manufacturers of RAM modules:
- Kingston.
- Crucial.
- Corsair.
- G. Skill.
- GOODRAM.
With a limited amount of money allocated to RAM, budget firms such as Team Group and AMD, which offer excellent value for money for their memory, are also excellent choices.
Try to avoid little-known and inexperienced RAM manufacturers, even if they offer a very "delicious" price. Also read the reviews of the memory kits you are interested in before purchasing them.
Output
Modern PCs can perform a huge number of tasks, from processing photos and playing movies, to running modern games and demanding graphics programs. And if simple tasks can be performed on simple hardware, then “heavy” applications require a powerful processor, a modern video card and, of course, fast RAM. You can choose for your computer thanks to our detailed recommendations. If you have any questions, we are always happy to answer them. Enjoy the shopping!
Memory DDR3 is gradually losing its position as the most massive and is no longer recommended for assembling new systems. Another thing is if the task is to upgrade a slightly outdated computer, and within a limited budget. Of course, such conditions exclude the most overclocked memory kits from the list of options, and they are not considered in our review.
Notably, within the platform Intel the race for megahertz does not make much sense either. The exception here is rather specific tasks that are of no interest to most users. On the other hand, the price difference between memory kits of the same size but with different clock speeds is vanishingly small (in the range from 2133 to 3000 MHz, of course). So why not choose a faster RAM set for the future?
The situation is completely different with the newest platform. AMD. Due to the peculiarities of their internal architecture, the performance of Ryzen processors directly depends on the operating frequency of the Infinity Fabric memory bus, and therefore its controller. In turn, the frequency of the latter is “tied” to the characteristics of the installed modules and can be increased by overclocking.
An extremely unpleasant nuance in the choice of memory modules for Ryzen is that not every kit will work in such a system even at its nominal clock frequency. There is already a problem in the features of the architecture of the modules themselves. Briefly, the recommendations can be reduced to two tips: focus on peer-to-peer memory sticks and the latest BIOS revision for the motherboard. The newer the AGESA protocol in it, the better. Keep in mind, dual rank memory with Ryzen will always work on lower frequencies, and earlier versions of this protocol "friendly" accept only modules based on Samsung chips. And not any, but exclusively the B-Die generation.
Happy upgrade!
My respects, dear site visitors. In a previous article, I wrote about . Now, having learned what it is and why and how it serves, many of you are probably thinking about getting a more powerful and productive RAM for your computer. After all, increasing computer performance with the help of additional memory RAM is the simplest and cheapest (unlike a video card, for example) method of upgrading your pet.
And ... Here you are standing at the showcase with packages of RAM. There are many and they are all different. Questions arise: And what RAM to choose?How to choose the right RAM and not miscalculate?What if I buy a RAM, and then it will not work? These are perfectly reasonable questions. In this article, I will try to answer all these questions. As you already understood, this article will take its rightful place in the series of articles in which I wrote about how to choose the right individual computer components i.e. iron. If you haven't forgotten, the articles included:

RAM and its main characteristics.
When choosing RAM for your computer, you must definitely build on your motherboard and processor, because RAM modules are installed on the motherboard and it also supports certain types of RAM. Thus, the relationship between the motherboard, processor and RAM is obtained.
Find out about What RAM does your motherboard and processor support? you can visit the manufacturer's website, where you need to find the model of your motherboard, as well as find out which processors and RAM it supports for them. If this is not done, it will turn out that you bought a super modern RAM, but it is not compatible with your motherboard and will gather dust somewhere in your closet. Now let's go directly to the main technical characteristics of RAM, which will serve as a kind of criteria when choosing RAM. These include:
Here I have listed the main characteristics of RAM, which you should pay attention to first of all when buying it. Now let's open each of them in turn.
RAM type.
Today, the most preferred type of memory in the world are memory modules. DDR(double data rate). They differ in time of release and of course technical parameters.
- DDR or DDR SDRAM(translated from English. Double Data Rate Synchronous Dynamic Random Access Memory - synchronous dynamic memory with random access and double the data transfer rate). Modules of this type have 184 contacts on the bar, are powered by a voltage of 2.5 V and have a clock frequency of up to 400 megahertz. This type RAM is already obsolete and is used only in old motherboards.
- DDR2- a type of memory that is widely used at this time. It has 240 contacts on the printed circuit board (120 on each side). Consumption, unlike DDR1, is reduced to 1.8 V. The clock frequency ranges from 400 MHz to 800 MHz.
- DDR3- the leader in performance at the time of this writing. It is no less common than DDR2 and consumes 30-40% less voltage than its predecessor (1.5 V). Has a clock frequency up to 1800 MHz.
- DDR4- a new, super modern type of RAM, ahead of its counterparts both in performance (clock frequency) and voltage consumption (which means less heat dissipation). Announced support for frequencies from 2133 to 4266 MHz. At the moment, these modules have not yet entered mass production (they promise to release them into mass production in mid-2012). Officially, fourth-generation modules operating in the DDR4-2133 at a voltage of 1.2 V were presented at CES by Samsung on January 04, 2011.
The amount of RAM.
I will not write much about the amount of memory. Let me just say that it is in this case that size matters 🙂
All a few years ago, 256-512 MB of RAM satisfied all the needs of even cool gaming computers. At present, for normal functioning, only operating system windows 7 requires 1 GB of memory, not to mention applications and games. There will never be an extra RAM, but I'll tell you a secret that 32-bit windows uses only 3.25 GB of RAM, even if you install all 8 GB of RAM. You can read more about this.
The dimensions of the slats or the so-called Form Factor.
Form-factor- these are the standard sizes of RAM modules, the type of design of the RAM strips themselves.
DIMM(Dual InLine Memory Module - double-sided type of modules with contacts on both sides) - mainly designed for desktop stationary computers, and SODIMM used in laptops.
Clock frequency.
This is a pretty important technical parameter of RAM. But the motherboard also has a clock frequency, and it is important to know the operating bus frequency of this board, since if you bought, for example, a RAM module DDR3-1800, and the slot (connector) of the motherboard supports the maximum clock frequency DDR3-1600, then the RAM module as a result will operate at a clock frequency of 1600 MHz. In this case, all sorts of failures, errors in the operation of the system and are possible.
Note: Memory bus speed and processor speed are completely different concepts.
From the above tables, you can understand that the bus frequency, multiplied by 2, gives the effective memory frequency (indicated in the “chip” column), i.e. gives us the data transfer rate. The title tells us the same. DDR(Double Data Rate) - which means double the data rate.
For clarity, I will give an example of decoding in the name of the RAM module - Kingston/PC2-9600/DDR3(DIMM)/2Gb/1200MHz, where:
— Kingston- manufacturer;
— PC2-9600— the name of the module and its throughput;
- DDR3(DIMM)- type of memory (form factor in which the module is made);
— 2GB is the volume of the module;
- 1200MHz— effective frequency, 1200 MHz.
throughput.
Bandwidth- a characteristic of memory, on which the performance of the system depends. It is expressed as the product of the system bus frequency and the amount of data transmitted per clock cycle. Bandwidth (peak data rate) is a composite measure of the capability RAM, it takes into account baud rate, bus width and the number of memory channels. The frequency indicates the potential of the memory bus per clock - at a higher frequency, more data can be transferred.
The peak indicator is calculated by the formula: B=f*c, where:
B is the bandwidth, f is the transmission frequency, c is the bus width. If you use two channels for data transmission, multiply everything received by 2. To get a figure in bytes / s, you need to divide the result by 8 (because there are 8 bits in 1 byte).
For better performance memory bus bandwidth And processor bus bandwidth must match. For example, for Intel processor core 2 duo E6850 with 1333 MHz system bus and 10600 Mb/s bandwidth, you can install two modules with 5300 Mb/s bandwidth each (PC2-5300), in total they will have a system bus bandwidth (FSB) equal to 10600 Mb /s .
Bus frequency and bandwidth are denoted as follows: " DDR2-XXXX" And " PC2-YYYY". Here "XXXX" indicates the effective memory frequency, and "YYYY" indicates the peak bandwidth.
Timings (latency).
Timings (or latency) are the time delays of the signal, which, in technical specification RAM is written as 2-2-2 " or " 3-3-3 " etc. Each digit here expresses a parameter. In order, it's always CAS Latency” (cycle time), “ RAS to CAS Delay” (full access time) and “ RAS Precharge Time» (precharge time).
Note
So that you can better understand the concept of timings, imagine a book, it will be our RAM, which we access. Information (data) in a book (RAM) is divided into chapters, and chapters consist of pages, which in turn contain tables with cells (like in Excel tables). Each cell with data on the page has its own vertical (columns) and horizontal (rows) coordinates. The RAS (Raw Address Strobe) signal is used to select a row, and the CAS (Column Address Strobe) signal is used to read a word (data) from the selected row (i.e., to select a column). A complete reading cycle begins with the opening of the "page" and ends with its closing and reloading, because. otherwise, the cells will be discharged and the data will be lost. This is how the algorithm for reading data from memory looks like:
- the selected "page" is activated by the RAS signal;
- data from the selected row on the page is transmitted to the amplifier, and the data transfer requires a delay (called RAS-to-CAS);
- a CAS signal is given to select (column) a word from that row;
- data is transferred to the bus (from where it goes to the memory controller), while there is also a delay (CAS Latency);
- the next word goes already without a delay, since it is contained in the prepared line;
- after the row access is completed, the page is closed, the data is returned to the cells, and the page is recharged (the delay is called RAS Precharge ).
Each digit in the designation indicates how many bus cycles the signal will be delayed. Timings are measured in nano-seconds. The numbers can have values from 2 to 9 . But sometimes a fourth one is added to these three parameters (for example: 2-3-3-8 ), called " DRAM Cycle Time Tras/Trc” (characterizes the performance of the entire memory chip as a whole).
It happens that sometimes a cunning manufacturer indicates only one value in the characteristics of the RAM, for example " CL2” (CAS Latency), the first timing is equal to two cycles. But the first parameter does not have to be equal to all timings, and maybe less than others, so keep this in mind and don't fall for the manufacturer's marketing ploy.
An example to illustrate the impact of timings on performance: a system with 100 MHz memory with 2-2-2 timings has about the same performance as the same system at 112 MHz, but with 3-3-3 delays. In other words, depending on latency, the performance difference can be as high as 10%.
So, when choosing, it is better to buy memory with the lowest timings, and if you want to add a module to an already installed one, then the timings of the purchased memory must match the timings of the installed memory.
Memory modes.
RAM can work in several modes, unless of course such modes are supported by the motherboard. This single channel, two-channel, three-channel and even four-channel modes. Therefore, when choosing RAM, you should pay attention to this parameter of the modules.
Theoretically, the speed of the memory subsystem in the dual-channel mode increases by 2 times, in the three-channel mode - by 3 times, respectively, etc., but in practice, in the dual-channel mode, the performance increase, in contrast to the single-channel mode, is 10-70%.
Let's take a closer look at the types of modes:
- Single channel mode(single-channel or asymmetric) - 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, frequency of operation, or manufacturer. It does not matter in which slots and which memory to install. All memory will run at the speed of the slowest memory installed.
- dual mode(dual-channel or symmetrical) - the same amount of RAM is installed in each channel (and theoretically there is a doubling of the maximum data transfer rate). In dual-channel mode, memory modules work in pairs 1st with 3rd and 2nd with 4th.
- Triple Mode(three-channel) - the same amount of RAM is installed in each of the three channels. Modules are selected by speed and volume. To enable this mode, modules must be installed in slots 1, 3, and 5/or 2, 4, and 6. In practice, by the way, this mode is not always more productive than dual-channel, and sometimes even loses to it in data transfer speed.
- Flex Mode(flexible) - allows you to increase the performance of RAM when installing two modules of different sizes, but the same frequency. As in the dual-channel mode, memory boards are installed in the same-named connectors of different channels.
Usually the most common option is dual-channel memory mode.
To work in multichannel modes, there are special sets of memory modules - the so-called Kit memory(Kit-set) - this kit includes two (three) modules, from the same manufacturer, with the same frequency, timings and memory type.
Appearance of KIT-sets:
for dual channel mode
for 3-channel mode
But the most important thing is that such modules are carefully selected and tested by the manufacturer to work in pairs (triples) in two- (three-) channel modes and do not imply any surprises in operation and configuration.
Module manufacturer.
Now on the market RAM well-established manufacturers such as: Hynix, amsung, Corsair, Kingmax, Transcend, Kingston, OCZ…
Each company has its own for each product. marking number, by which, if you decipher it correctly, you can learn a lot for yourself useful information about the product. For example, let's try to decipher the module marking Kingston families ValueRAM(see image):
Decryption:
- KVR– Kingston ValueRAM i.e. manufacturer
- 1066/1333 – operating/effective frequency (Mhz)
- D3- type of memory (DDR3)
- D (Dual) - rank / rank. A dual-rank module is two logical modules soldered on the same physical one and using the same physical channel in turn (required to achieve the maximum amount of RAM with a limited number of slots)
- 4 – 4 DRAM memory chips
- R-Registered, indicates stable operation without failures and errors for as long as possible a continuous period of time
