9 Best RAM For Desktop PC

Working memory, also known as RAM memory, is a computer's short-term memory. Unlike the hard disk that stores data for a long time, the data in the main memory is only stored until the computer is turned off again. If the computer repeatedly reaches its limit with complex programs or several programs at once, then the problem is usually that the main memory is too small. So many Windows crashes because of it. If a memory test with the Windows Memory Diagnosis test tool reveals this, there's a good option: expanding working memory. Main memory can be expanded with the best RAM for desktop PC of the same construction or not, which is available from many well-known manufacturers.

What is RAM?

best RAM

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

In other words, this means: the more RAM available, the more or more complex processes can run concurrently. In addition to the processor, the main memory greatly determines the overall performance and work speed of the computer. It plays an important role for gamers, for example, who run other programs like communication software and the like while playing computer games.

Main memory is often referred to as RAM memory in technical circles. The term RAM comes from English and stands for "Random Access Memory". How much RAM memory a PC user needs depends on their usage behavior. Office PCs for general office programs make up much less main memory requirements than gaming computers or PCs for trimming or editing audio and video files. In the first scenario, 4 gigabytes is usually enough out, 8 gigabytes of RAM is better. In the second case, it should be 16 gigabytes, 32 or even 64 gigabytes of RAM better if the 4K video is edited.

Not suitable for every operating system: Not every operating system, for example Windows, can use this much memory. There is a big dividing line between so-called 32- and 64-bit systems. More on that in the guide below.

Unlike regular hard drives, the best RAM memory only retains the data it contains until the computer shuts down. Main memory is also sometimes referred to as "volatile memory". It has transfer speeds up to 250 times faster than external or internal hard drives and is also known as "primary storage" or "fast storage". RAM memory should not be confused with hard drives as they don't have much in common with each other, even though they both store data.

In computers, the main memory is located on what is called the mainboard, also known as the motherboard or main circuit board. There are ready-made RAM slots available. How much memory can be installed on the computer depends on how many slots the internal mainboard has.

When should RAM be upgraded?

If your own computer repeatedly reaches its performance limit in daily use and causes errors or crashes, it is time to provide it with new RAM capacity. Many users wonder how to determine when memory usage is too high. It's relatively easy: Under Windows, the Task Manager can be invoked with the Ctrl + Alt + Del key combination. The usage of each hardware component can be seen under the "Performance" tab.

How do I see the RAM on an Apple computer? Mac memory usage can be checked by searching for Utilities and selecting the Memory tab in Activity Monitor.

However, a glance does not provide reliable data. To obtain meaningful results, the computer must be monitored daily for a period of one week in daily use. If usage is more than 80 or 90 percent daily, it makes sense to consider the best RAM upgrade. However, it should always be considered that the simultaneous use of different programs has a high impact on memory usage. A memory test with the Windows Memory Diagnosis test tool also makes sense to reveal the reason for the error. An alternative to memory diagnostics is the freeware MemTest. MemTest also checks memory for errors.

Important characteristics of RAM memory

Memory for PCs is sold in oblong RAM modules. They differ in terms of memory size, memory type and memory speed:
  • Memory size: Most memory modules on the market are sold separately or are called memory kits. Kits are available in sizes from 4 to 8 gigabytes per cartridge. Older models from the early 2000s, if you can find them, are available in smaller sizes of 1 or 2 gigabytes. The rule of thumb is: the more RAM, the better.
  • Storage types: Manufacturers are launching new generations of storage at rapid intervals, which are getting bigger, faster, and more energy efficient. However, computers are durable devices and cannot be reassembled indefinitely. Therefore, despite the state of the art, memory modules are often required which are actually considered outdated.
  • Memory tempo: The memory tempo shows the clock frequency. This is the speed at which the CPU unit can access the RAM memory. Today's memory sticks reach clock frequencies of up to 3,000 megahertz, and sometimes peak values ​​are even higher. The outdated alternatives that can still be found on the market are in the 800 to 2,400 megahertz range. Older models installed on PCs between 2000 and 2008 are sometimes much lower.
It should always be noted that certain generation models cannot be installed on computers whose mainboard was designed for the previous generation. Example: Common types of DDR3 RAM are not backward compatible. Therefore, the RAM to be installed must match the RAM module already installed in the PC. The FAQ section below explains how users can find out which memory module they have installed.

Interesting facts about the history of the origin of DDR main memory

best RAM

The emergence of modern working memory began shortly before the turn of the millennium. Since mid-1999, well-known IT manufacturers have been trying to bring new RAM technologies to the market. However, those efforts quickly failed, causing manufacturers to focus more on DDR modules, which were already on the rise by then.

It wasn't until 2002 that buyers received the new technology with DDR modules. Since then, the performance has continued to improve - the success of modern DDR modules has been programmed. Over time, not only the requirements for storage capacity increase, but also for the clock frequency of each module. Increasingly complex systems and programs require consistent further development.

In the first few years, manufacturers can still meet the needs of users with subsequent developments. But that changed because of the great limitations of the technology used until now. Neither speed nor storage capacity can be increased anymore due to the technology used.

It's time to launch new standards and memory modules. This has been achieved with the DDR2 standard. It spreads to normal desktop and notebook PCs. With up to four individual modules and much higher clock frequencies, DDR2 main memory finds its way into many computers.

The next generation of working memory, DDR3 RAM, is still used in many PCs today. Due to the possibility of combining many modules with each other, high performance and large storage capacity can be achieved. In 2014, DDR4 memory finally hit the market. It quickly established itself through high-quality modules, constant further development of the clock frequency and high storage capacity.

Long guarantees on DDR4: Some manufacturers give guarantees of up to 10 years on DDR4 bars. In the event of a defect, users can rely on competent help as long as they keep the guarantee document safe. A copy of the invoice or receipt is recommended here.

What types of RAM are there?

There are the following types of memory:
  • DDR4 RAM
  • DDR3 RAM
  • DDR2 RAM
The abbreviation DDR in this context is sometimes misunderstood. It stands for "Double Data Rate" and has nothing to do with the former German Democratic Republic.


DDR4 RAM memory is the latest version of RAM, which first appeared on the market in 2012, but only managed to establish itself firmly in 2014. A DDR4 RAM usually has 288 pins for connection to the mainboard for the desktop version and 260 pins for the laptop version. DDR4 RAM runs at 1.2 or 1.35 volts, which is lower than other models, which should allow for higher clock speeds and faster access to cached data.

Data processing speed is 12,800 to 25,600 megabytes per second and more. Memory sticks are available in 4, 8, 16, 32 and 64 gigabytes offered. DDR4 is also the first RAM version to work with a technology called chip stacking. This allows stacking of up to eight storage layers to achieve higher storage capacity and better signal strength.

  • Chip stacking technique
  • Powerful and energy efficient
  • Improved storage capacity and signal quality
  • Most expensive to buy


DDR3 RAM is the direct successor to DDR2 memory and is still used in many computers today. A transmission rate of 6,400 to 19,200 megabytes per second is achieved. The number of contacts is 240 for desktop PCs and 204 for laptops. DDR3 modules are attractive for many gaming and multimedia applications because of their low cost. They are usually offered in the form of 4, 8 or 16 gigabyte bars.

  • Significantly faster than DDR2 RAM
  • Usable for mobile devices
  • Lower voltage consumption than DDR2
  • Compatible with most motherboards
  • Slower than DDR4
  • Less future-oriented than DDR4 RAM
  • More expensive to buy than DDR2


DDR2 RAM came to the market in 2005 as a successor to conventional DDR working memory. Like DDR3 RAM, it has 240 contacts to connect to the mainboard, but is not compatible with newer versions of RAM. The transmission rate is between 3,200 and 8,500 megabytes per second. DDR2 RAM is typically offered in 2, 4 and 8 gigabyte modules, but is rarely found on the market today.

  • Very inexpensive
  • Comparatively low performance
  • Hard to find
  • Low compatibility with end devices

All RAM modules for conventional desktop PCs follow the DIMM architecture. SO-DIMM stands for "Small Outline Dual Inline Memory Module" and describes a main memory technology specifically developed for notebooks and laptops. It is a subcategory of its own, offered as DDR2, DDR3, and DDR4 memory. The difference with regular RAM sticks lies in the much smaller size of the modules, as they have to fit into a narrow laptop case.

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

Important purchasing criteria for RAM

best RAM

There are several things to consider when buying new memory. This includes:
  • Design: First, you have to make sure that the new memory fits into the computer. You should pay attention to the design which is divided into DIMMs and SO-DIMMs. Memory modules with DIMM designs are suitable for regular desktop PC mainboards, while more compact SO-DIMM modules are intended for mini PCs mainboards and laptops. You should also pay attention to the number of contacts available, because there is a difference between DDR3 and DDR4 RAM. The computer or mainboard manual contains precise information about which RAM modules are compatible.
  • RAM type: There are almost no DDR2 modules on the market today, so only DDR3 RAM and DDR4 RAM can be used. The DDR3 version works a little slower, but is cheap. If you want to get the most out of your computer, you should spend more money and invest in DDR4 RAM. The type of slots available on the mainboard is also important, because DDR3 RAM cannot be used in DDR4 slots.
  • Storage capacity: How high the storage capacity of a new RAM module should be depends on personal usage behavior. Computing-intensive computer programs or games require significantly more RAM than typical office applications. Most users come with 8 to 16 gigabytes of storage capacity easily. Most computers cannot use more than 32 or 64 gigabytes.
  • Memory latency: Memory latency is the number of times memory sends data to the processor per clock cycle. This value is often specified by the manufacturer as CL or "Column Strobe Latency". The following applies: the lower the memory latency, the faster the memory responds. Therefore, memory that works with CL5 is slower than RAM memory that works with CL2.
  • Number of RAM modules: Most motherboards have four slots for RAM modules. But there are also computers with more or fewer slots. A look at the manual for the mainboard should answer all the questions. It makes sense to buy all memory sticks from the same manufacturer. This minimizes the risk of technical difficulties. Anyone who decides to use modules from different manufacturers should remember that computers always adapt to the slowest hardware.
  • Clock frequency: The clock frequency of the RAM memory determines the access time at which stored data can be transferred. Values ​​are given in mega transfers per second, or MT/s for short. Most manufacturers often use the megahertz to indicate speed. It is important that the clock frequency of the main memory matches the working speed of the processor. The appropriate table can usually be found in the manual for the processor or computer.
  • Dimensions: Before buying, the inventor should get a general idea of ​​how much space is available in the computer case. Otherwise, there is a risk that the main memory has the correct connections but is too large to fit into the PC. This aspect mainly plays a role in laptops and notebooks, less often on desktop PCs.
  • Voltage: The mains voltage in volts used by main memory plays a role when it is overclocked. Voltage and clock speed are closely related and should always be well matched. The correct relationship between the two values ​​is usually set automatically by the mainboard via the SPD-ROM chip. However, the value can also be reset manually via the PC BIOS.
How is RAM memory installed correctly?

Contrary to most expectations, installing a new RAM stick is not rocket science. However, do-it-yourselfers should pay attention to a few things when installing:
  1. In the first step, the computer must be turned off, disconnected from the power supply, and grounded to the radiator, for example.
  2. The computer is then opened to get an overview. It is important to find a slot for the main memory on the mainboard.
  3. If necessary, the old RAM modules are now removed by loosening the small safety levers at the ends of each rail and then gently pulling the main memory out.
  4. Now the new RAM is carefully inserted, paying attention to the click of the safety lever. Just after a click, the new RAM has contact with the motherboard or mainboard and is properly installed.
  5. The computer should then be restarted and the task manager or computer management should be checked to see if the correct storage capacity of the new main memory is displayed.
  6. If everything is as it should be, the computer is finally shut down again, disconnected from the power supply, grounded, and then plugged back in properly.
Overview of leading manufacturers and brands

As with almost all products, there are also several RAM manufacturers who are able to establish themselves as market leaders.
  • Corsair: The US company Corsair, founded in 1994, specializes in high-performance memory modules that are especially popular with gamers. The manufacturer now also sells main memory in a lower price range under the product name "ValueSelect". The company is based in Fremont, California, and went public on the US technology exchange NASDAQ in September 2020.
  • Kingston: "Kingston Technology" is an American memory product manufacturer headquartered in Fountain Valley, California. Founded in 1987, this company sells a wide range of computer hardware at relatively low prices. The first European branch opened in 1995 in the Bavarian capital, Munich. In 2017, the company recorded sales of more than 10 billion US dollars for the first time. Many other branches followed. Today, Kingston Technology, under its HyperX brand, is 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 is still part of the American technology company based in Boise, Idaho. According to the manufacturer, it means knowledge, compatibility and reliability. Crucial offers a wide variety of memory modules that have something for gamers as well as for the occasional computer user. According to Micron Technology, it employs more than 30,000 people and generates annual sales of more than 30 billion US dollars.
Frequently asked questions about RAM

Which is the best RAM memory?

It depends on the requirements. For example, a gamer is more likely to look for higher quality than a home office worker looking for a little more storage for their laptop. Therefore, it is important to know your own needs before buying the best RAM memory. You can then see a comparison of these products and crown the winner of the personal test.

Where can you buy RAM?

The best RAM can be purchased at a local electronics store or online from an online retailer. Anyone with little experience with RAM memory and other PC components can find helpful personal buying advice from trained local shop staff. Otherwise, online retailers have more advantages. They offer a large number of products to compare and 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 stick, the higher the price. One 4 gigabyte module is usually cheaper than two 2 gigabyte modules each.

4 gigabytes of DDR3 RAM are usually between 70 and $100. While there are big outliers up or down, most providers are somewhere within the stated price range. DDR4 RAM sticks are even more expensive than DDR3 modules.

Which is more important: big or fast RAM memory?

The two are difficult to separate. Higher clock frequencies are always desirable, as RAM memory is responsible for the data that the computer needs to access temporarily. The bigger the RAM memory, the more the system can swap it out. However, all the storage capacity in the world is useless if the transfer speed or RAM access speed is slow and swapping slows down.

The assumption that a memory stick with a capacity of 16 gigabytes can clock slower than a smaller module is wrong. Therefore, a good balance between speed and size should always be sought. Existing system and your own wallet that determines how fast and how much RAM memory.

Where is the information about the computer's RAM?

As already mentioned in the guide, many users have no idea what RAM they have on their computer. The oldest trick in the world is to simply open the computer - we explained how it works above and take a look at the memory stick itself. There is usually noted the type of memory and how big and fast. This variant is recommended if the computer is not in a factory or used condition.

How much RAM does the game need?

This depends on the type of game and the resolution and level of detail being played. Therefore, a general answer is difficult. There are now 8 or 16 gigabytes the absolute standard in gaming PCs. If you have high demands on graphics, you should spend more money and invest in 16 gigabytes of RAM. Until recently, 32 gigabytes were rarely needed - experts debated whether 32 gigabytes really brought any added value to gaming.

When in doubt, more RAM is never bad - especially for gamers using up-to-date and powerful graphics cards that don't slow down RAM memory. Because games, like any technology, evolve rapidly with the demands of hardware.

What is meant by dual channel?

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 the best two sticks of RAM at the same time. To do this, at least two RAM modules must be plugged into the same colored slots on the mainboard. Ideally, the sticks are all from the same manufacturer and follow the same model.

How is memory cleared?

The cooperation between the CPU, memory and the operating system is usually so good that the user does not need to intervene. In fact the opposite can happen. Cleaning RAM manually too often can cause crashes or decreased performance. So if the main memory is always full, it is recommended to add the best RAM instead of interrupting the automatic process.

If you still want to free up RAM more often for some reason, we recommend using a RAM optimization program. They are available for Windows and macOS. Another solution is to restart the PC which will close all applications. It also clears memory. After shutdown, redundant stored files will be deleted and only running programs get new resources.


DDR4 RAM is indispensable for modern computer systems. The quality is very qualified to run heavy and complex programs. Even though it is sophisticated, it still requires precision in choosing it so that the costs incurred are balanced and not wasteful.

The capacities of 4 GB, 8 GB, and 16 GB have their respective advantages. Make sure you choose the best RAM for your desktop PC according to your needs and compatible with your motherboard, OK!
