9 Different main memories (ram) in comparison – find your best main memory for the maximum performance of your system – our test resp. Advisor 2022

Daniel Wolf

The main memory, also called RAM memory, is the short-term memory of a computer. In contrast to a hard disk, which stores data for a long time, the data in a RAM only remains stored until the computer is switched off again. If the computer repeatedly reaches its limits with complex programs or several programs at the same time, then too little RAM is usually the problem. Many Windows crashes can be traced back to this. If the memory test with the Windows Memory Diagnostics test tool reveals this, there’s a good option: expand the RAM. The RAM can be expanded with identical or non-identical RAM bars, which are available from many renowned manufacturers.

The following working memory comparison presents 9 modern RAM bars and compares them in terms of factors such as performance, speed and compatibility. A subsequent guide deals in detail with the functionality of RAM memories, the different memory types and the correct installation of the small bars. A FAQ section of the buyer’s guide provides competent answers to questions that are always asked in relation to RAM memory. Finally, here’s a look at whether Stiftung Warentest oroko-Test has already conducted a RAM test and if so, how the products fared there.

What is a RAM?

Working memory test

The main processor or CPU, short for "central processing unit", of a computer is often referred to in specialist circles as the brain of the PC. Following this terminology, the main memory serves as the computer’s short-term memory. As a component of the central processing unit, RAM is the part of the computer that the processor must constantly access during operation. All running processes are stored in it.

In other words: The more RAM is available, the more or the more complex processes can run simultaneously. Besides the processors, the RAM is crucial for the overall performance and working speed of a computer. This plays an important role for gamers, for example, who still have to run other programs such as communication software and so on while playing a computationally intensive game. run.

The main memory is often referred to as RAM memory in specialist circles. The term RAM comes from the English and stands for "random access memory". How much RAM memory a PC user needs depends on his usage behavior. An office PC for common office programs makes significantly fewer demands on the main memory than a gaming computer or a PC for cutting or editing audio and video files. In the first scenario, 4 gigabytes are usually sufficient, 8 gigabytes of RAM are better. In the second case, it should be 16 gigabytes, 32 or even 64 gigabytes of RAM are better if 4K videos are to be edited.

Unlike a normal hard disk, RAM memory only stores the data it contains until the computer is switched off. The main memory is therefore sometimes also referred to as "volatile memory". It has transfer rates up to 250 times faster than an external or internal hard disk and is known as "main memory" or "fast memory" among other things. RAM memory should not be confused with hard drives, as they don’t have much to do with each other, even though both store data.

In the computer, the RAM sits in the so-called mainboard, also known as motherboard or motherboard. There are pre-installed RAM slots there. How much RAM a computer can be upgraded with depends on how many slots the installed mainboard has.

When should a working memory be upgraded?

If your own computer repeatedly reaches its performance limits in everyday use and causes errors or crashes, it’s time to provide it with new RAM capacity. Many users ask themselves how they can determine that the working memory is being used too much. This is relatively easy: Under Windows, the Task Manager can be called up with the key combination Ctrl + Alt + Del. Under the "Performance" tab, the workloads of the individual hardware components can be viewed.

However, a one-time look does not yet provide reliable data. In order to obtain meaningful results, the computer must be monitored every day during everyday use over a period of one week. If the workload is more than 80 or 90 percent every day, it makes sense to think about upgrading the RAM. However, it should always be taken into account that the simultaneous use of different programs has a high influence on the RAM load. The memory test with the Windows memory diagnostics test tool also makes sense to reveal the reason for the errors. An alternative to memory diagnostics is the freeware MemTest. MemTest also checks the working memory for errors. MemTest can test the memory reliability over a longer period of time.

Important characteristics of RAM memory

RAM for the PC is sold in elongated RAM modules. They differ in terms of memory size, memory type and memory speed:

  • memory size: Most memory modules on the market are offered individually or as so-called memory kits. Kits are available in sizes from 4 to 8 gigabytes per plug-in module. ÄOlder models from the early 2000s are available in smaller sizes of one or 2 gigabytes, if they can still be found. The rule of thumb is: the more RAM memory, the better.
  • Memory type: Manufacturers bring new memory generations onto the market in rapid succession, which are becoming ever larger, faster and more power-efficient. However, computers are long-lived devices and cannot be upgraded indefinitely. Therefore, regardless of the state of the art, memory modules are often needed that are actually considered obsolete.
  • Memory speed: The tempo of a working memory indicates the clock frequency. This is the speed at which the CPU unit can access the RAM memory. Current memory modules achieve clock frequencies of up to 3.000 megahertz, in some cases the peak values are even higher. Outdated alternatives that can still be found on the market are in the range of 800 to 2.400 megahertz. ÄOlder models, which were installed in PCs between the years 2000 and 2008, are sometimes significantly below this level.

It should always be noted that models of a certain generation cannot be installed in computers whose mainboards are designed for the previous generation. For example, the common RAM type DDR3 is not backward compatible. The RAM to be retrofitted must therefore correspond to the RAM modules already installed in the PC. The FAQ section below explains how users find out which memory modules they have installed.

Interesting facts about the history of the DDR working memory

Best memory

The emergence of modern working memory began shortly before the turn of the millennium. From the middle of 1999 onwards, well-known IT manufacturers tried to bring new techniques for main memory onto the market. However, the attempts quickly failed, whereby the manufacturers concentrated more and more on DDR modules instead, which were already on the rise at that time.

Only in 2002 the new technology with the DDR modules was accepted by the buyers. Since then, performance has continued to increase- a success of modern DDR modules was programmed. In the course of time, not only the requirements for memory capacity increased, but also for the clock frequency of the individual modules. The increasingly complex systems and programs required consistent further development.

In the first years the manufacturers could still meet the requirements of the users with their further developments. However, this changed due to the massive limitations of the technology previously used. Both the speed and the memory capacity could no longer be increased due to the technology used.

You should remember this!

It was time to bring new standards and modules for RAM to the market. With the DDR2 standard, this succeeded. It became widespread in both normal desktop PCs and notebooks. With up to four individual modules and a much higher clock frequency, DDR2 RAM has found its way into many computers.

The following generation of RAM, the DDR3 RAM, is still used in numerous PCs today. The ability to combine many modules together allows high performance and large memory capacity to be achieved. DDR4 memory finally came onto the market in 2014. It quickly established itself due to the high-quality modules, a constant development of the clock frequency and a high memory capacity.

What types of RAM are there?

There are the following types of RAM:

  • DDR4 RAM
  • DDR3 RAM
  • DDR2 RAM

The abbreviation DDR in this context is sometimes misinterpreted. It stands for "Double Data Rate" and has nothing to do with the former German Democratic Republic.


DDR4 RAM is the latest version of RAM, which first appeared on the market in 2012, but only became firmly established in 2014. A DDR4 RAM usually has 288 contacts for connection to the motherboard for the desktop version and 260 contacts for the laptop version. DDR4 RAM operates at a lower voltage of 1.2 or 1.35 volts compared to other models, which should enable higher clock rates and faster access to cached data.

The data processing rate is 12.800 to 25.600 megabytes per second and more. The memory bars are offered in 4, 8, 16, 32 and 64 gigabytes. DDR4 is also the first RAM version that works with the so-called chip stacking technology. It makes it possible to stack up to eight memory layers on top of each other to achieve a higher memory capacity and better signal strengths.

  • Chip stacking technology
  • Powerful and energy-efficient
  • Improved memory capacity and signal quality
  • Most expensive to buy


DDR3 RAM is the direct successor to DDR2 RAM and is still used in many computers today. Transfer rates of 6.400 to 19.Reaches 200 megabytes per second. The number of contacts is 240 for desktop PCs and 204 for laptops. Due to their low acquisition costs, DDR3 modules are interesting for many gaming and multimedia applications. They are usually offered in the form of 4-, 8- or 16-gigabyte bars.

  • Much faster than DDR2 RAM
  • Can be used for mobile devices
  • Lower voltage consumption than DDR2
  • Compatible with most motherboards
  • Slower than DDR4
  • Less future-oriented than DDR4 RAM
  • More expensive to purchase than DDR2


DDR2 RAM came onto the market in 2005 as the successor to conventional DDR RAM. Like the DDR3 RAM, it has 240 contacts for the connection to the motherboard, but is not compatible with the newer RAM version. The transfer rates are around 3.200 to 8.500 megabytes per second. DDR2 RAM is mostly offered in 2-, 4- and 8-gigabyte modules, but is hardly ever found on the market today.

  • Very inexpensive
  • Low performance in comparison
  • Hardly ever found
  • Low compatibility with end devices


All RAM modules for conventional desktop PCs follow the DIMM design. SO-DIMM stands for "Small-Outline-Dual-Inline-Memory-Module" and describes a main memory technology that was especially developed for notebooks and laptops. It is a subcategory of its own, which is offered as DDR2, DDR3 and DDR4 working memory. The difference to normal RAM sticks is the significantly smaller size of the modules, since they have to fit into the narrow case of laptops.

  • Suitable for notebooks and laptops
  • Not compatible with desktop PCs
  • Not suitable for all laptops
  • Limited availability and low supply

Important buying criteria for working memory

alt="Working memory comparison width="500" height="500" />There are a few things to consider when buying new RAM. These include:


  • Type of construction: The first thing to do is to make sure that the new RAM will fit in the computer. For this, attention must be paid to the design, which is divided into DIMM and SO-DIMM. Memory modules with DIMM design are suitable for mainboards of normal desktop PCs, while the more compact SO-DIMM modules are intended for the mainboards of mini PCs and laptops. You should also pay attention to the number of available contacts, as there are differences between DDR3 and DDR4 RAM here. Precise information about which RAM modules are compatible can be found in the manual of the computer or mainboard.
  • RAM type: DDR2 modules are hardly available on the market today, so only DDR3 RAM and DDR4 RAM come into question. The DDR3 version works a bit slower, but can be had at a low price in return. If you want to get the most out of your computer, you should spend more money and invest in a DDR4 RAM. The type of available slots on the mainboard is also important, because DDR3 RAM cannot be used in a DDR4 slot.
  • Memory capacity: How high the memory capacity of a new RAM module should be depends on the personal usage behavior. Much more RAM is required for computationally intensive programs or computer games than for normal office applications. Most users get by with a memory capacity of 8 to 16 gigabytes without any problems. Most computers can’t use more than 32 or 64 gigabytes anyway.
  • Memory latency: The memory latency indicates how often the working memory transmits data to the processor per clock cycle. The value is often specified by manufacturers as CL or "Column-Strobe-Latency". The following applies: The lower the memory latency, the faster the RAM reacts. A RAM with CL5 is therefore slower than a RAM with CL2.
  • Number of RAM modules: Most motherboards have four slots for RAM modules. However, there are also computers with more or fewer slots. A look in the manual of the motherboard should answer all questions about it. It makes sense to purchase all memory sticks from the same manufacturer. This minimizes the risk of technical difficulties. Who decides nevertheless for modules of different Herstellererr, should have in the back of the head that the computer always adapts to the slowest hardware.
  • Clock frequency: The clock frequency of a RAM memory indicates the access time in which stored data can be transferred. The value is given in the unit megatransfers per second, or MT/s for short. Most manufacturers often also use the unit megahertz to indicate the speed. It is important that the clock frequency of the RAM corresponds to the operating speed of the processor. A corresponding table can usually be found in the manual of the processor or computer.
  • Dimensions: Before buying, tinkerers should get an overview of how much space is available in the computer’s case. Otherwise, there is a risk that the working memory has the right connections, but is too big is to be installed in the PC. This aspect plays a role predominantly with laptops and notebooks, less frequently with desktop PCs.
  • Voltage: The electrical voltage in volts at which the main memory operates plays a role when it is to be overclocked. Voltage and clock rate are closely related to each other and should always be well coordinated. The correct ratio of the two values is usually set automatically by the mainboard via the SPD-ROM chip. ÜThe value can also be manually readjusted via the BIOS of the PC.

How to properly install RAM memory?

Tips & Hints

Contrary to most expectations, installing a new RAM bar isn’t witchcraft. However, do-it-yourselfers should keep a few things in mind during installation:

  1. In the first step, the computer should be turned off, disconnected from the power and grounded to a radiator, for example.
  2. The computer is then opened to get an overview of the system. It is important to find the slot for the working memory on the motherboard.
  3. If necessary, remove the old RAM modules by loosening the small safety levers at the end of the respective rail and then gently pulling out the RAM.
  4. Now the new RAMs are inserted carefully, paying attention to the click of the safety lever. Only after clicking does the new RAM make contact with the motherboard or mainboard and is installed correctly.
  5. The computer should then be restarted and the Task Manager or Computer Management should be checked to see if the correct memory capacity of the new RAM is displayed.
  6. If everything is as it should be, the computer is finally switched off, disconnected from the power supply, grounded and then screwed back on again properly.

An overview of leading manufacturers and brands

Working memory test and comparison

As with almost all products, there are also a few manufacturers that have been able to establish themselves as market leaders when it comes to working memory.

  • Corsair: Founded in 1994, the US company Corsair specializes in high-performance RAM modules, which are primarily popular among gamers. In the meantime, the manufacturer also sells working memory in the lower price ranges under the product name "ValueSelect. The company is based in Fremont in the US state of California and went public on the US tech exchange NASDAQ in September 2020.
  • Kingston: "Kingston Technology" is a U.S. manufacturer of memory products, headquartered in Fountain Valley in the state of California. The company, founded in 1987, sells a wide range of computer hardware at relatively low prices. The first European branch was opened in 1995 in the Bavarian capital Munich. In 2017, the company reported sales of more than $10 billion for the first time ever. Many other branches followed. Today, Kingston Technology with its HyperX brand is considered one of the world’s leading independent memory manufacturers.
  • Crucial: The semiconductor company now known as Crucial was founded in 1978 under the name "Micron Technology" and still belongs to that U.S. technology company headquartered in Boise in the state of Idaho. By their own admission, the manufacturer stands for expertise, compatibility and reliability. Crucial offers a wide range of memory modules, which has a lot in store for gamers as well as for the occasional computer user. Micron Technology says it employs over 30.000 employees and generates more than $30 billion in revenue per year.

FAQ: Frequently asked questions about RAM

Which is the best RAM?

It depends on the requirements. For example, a gamer is usually looking for higher quality than a home office worker looking for a bit more memory for their laptop. Therefore, it is important to be clear about your own requirements before buying a RAM memory. Then you can take a look at this product comparison and crown your personal test winner.

Where to buy RAM?

A RAM can be purchased either at a local electronics store or on the Internet from an online retailer. If you have little experience with RAM memory and other PC components, you might find personal purchase advice from a trained staff in your local store helpful. Otherwise, online retailers have more advantages. They offer a huge choice of products that can be compared and there is access to hundreds of reviews and testimonials from other customers.

How much does RAM cost?

It all depends on the size and speed of the RAM memory. The bigger the RAM bar is, the higher its price will be. A single 4 gigabyte module is usually cheaper than two modules with 2 gigabytes each.

4 gigabytes of DDR3 type memory is usually between 70 and 100 euros. There are big outliers upwards or downwards, but most providers are somewhere in the price range mentioned above. DDR4 RAM bars are once again more expensive than DDR3 modules.

Which is more important: large or fast RAM memory?

It is difficult to separate the two. A higher clock frequency is always desirable, because a RAM memory is responsible for data that the computer needs to access temporarily. The larger the RAM memory, the more the system can swap it out. All the storage capacity in the world is useless, however, if the transfer rates or the access speed of the RAM is slow and slows down outsourcing.

The assumption that memory bars with 16 gigabyte capacity can clock slower than smaller modules is wrong. Therefore, you should always look for a good balance of speed and size. The existing system and one’s own wallet decide how fast and how big the RAM memory is.

Where does the specification for the working memory of a computer stand?

As already mentioned in the guide, many users do not know what memory they have on their computer. The oldest trick in the world is to simply open the computer- how this works has already been explained above- and to look up on the memory boards themselves. It is usually noted there what type of memory it is and how large it is and fast it is. This variant is recommended if the computer is no longer in factory condition or is second-hand.

Another convenient way is to use a program like CPU-Z, which can be downloaded here for free. Software can be used to read the RAM without having to dig around in manuals or the innards of the PC. If you run the program, you will find out all the important information about the installed memory, the DDR types, the clock speed, the size and the RAM slots still available in the computer.

Which RAM memory do games need?

This depends on the type of game and in which resolution and detail level is played. A general answer is therefore difficult. Meanwhile, 8 or already 16 gigabytes are the absolute standard in gaming PCs. If you have high demands on the graphics, you should spend more money and invest in a 16 gigabyte RAM. 32 gigabytes are rarely necessary to date- In expert circles it is debated whether 32 gigabytes bring any added value at all when gaming.

When in doubt, however, more RAM is never a bad thing- Especially for gamers who use a current and powerful graphics card, which does not slow down the RAM memory. Because games, like technology, continue to develop rapidly and with them the demands on the hardware.

What does dual channel mean?

In principle, a computer can only access one RAM module at a time. With the so-called dual-channel function, it is possible to use two RAM bars at the same time. For this, at least two RAM bricks have to be inserted into the same-colored slot of the motherboard. Ideally, the sticks are all from the same manufacturer and follow the same model.

How to empty the RAM?

The cooperation between CPU, working memory and operating system is usually so good that users do not have to intervene additionally. Even the opposite can be the case. Too often manually emptied working memory can lead to crashes or reduced performance. So, if the RAM is always and constantly full, it is more advisable to increase the RAM instead of interfering with the automatic processes.

If you still want to empty your RAM frequently for certain reasons, you should use RAM optimization programs. They are available both for Windows and macOS. Another solution would be to restart the PC, closing all applications. This also empties the working memory. After shutdown, the superfluously stored files are deleted and only the executed programs receive renewed resources.

Is there a working time test by Stiftung Warentest?

The experts at Stiftung Warentest have not yet conducted their own memory test. And there aren’t any other articles or guides worth mentioning on the subject of RAM memory and PC utilization on the consumer organization’s website either. Should this change, this guide will be updated accordingly.

Is there a working memory test fromoko-Test?

Technical topics are less in focus atoko-Test, which is why there is no working memory test byoko-Test or similar articles on this topic on the website that are interesting for the reader.
