Keep in mind that the present state of the technology market is fairly difficult because there are hundreds of different memory kits available from tens of different brands.

Therefore, it is necessary for you to seek the assistance of professionals and exercise extreme caution while examining the various items. You can check out these eight goods, each of which comes with a comprehensive review, if you want to save yourself some time.

Quick Shopping Tips:


There are a number of companies who are producing RAM kits that are compatible with a wider variety of users and systems. It’s possible that this is why so many of our customers become confused when they’re trying to choose the brand name of their product.

Also, check out our separate post on Does Ram Brand Matter

In point of fact, the products themselves and how well the kit works are far more important than the name of the kit, which doesn’t matter all that much. I think you should choose a good-performing volatile memory that doesn’t break the bank instead of a certain brand name.

Memory size:

The overall memory capacity of the memory kit is the following most essential factor on the list in descending order. In case you were wondering, it’s a system-based factor that completely depends on the load, the requirements, and the usage.

You can’t go for anything with less than 8 gigabytes of memory on a gaming computer if you want to be competitive. The highest limits, on the other hand, are dependent once more on how much pressure you will place on the rig as well as the kinds of games that you will play on the computer system.

Clock speeds and overclocking: 

In addition to the other components, random access memory (RAM) has two different clock speeds: the base clock and the boost clock. The overclocking headroom is equal to the difference in score between the two ratings. There is a direct correlation between the clock speed and the overall performance of the computer.

You need to find a RAM kit that has higher clock rates and a larger overclocking gap than what you currently have. In addition to this, check to see if the motherboard is capable of supporting the appropriate clock rates.


The timings of the RAM, which are often referred to as CS latency, are another component that plays a significant part in the overall efficiency as well as the performance of the memory. It has a relationship that is inversely proportional to the speeds of the CPU and the computer.

You should look for a kit that has a CAS latency of 16 at the very least, but obviously, the lower, the better. If you have two different kits in front of you, the one that has lower timings will perform significantly better than the one that has greater latencies and will give you with a significantly higher level of performance.

Go through our epic guide on DRAM Frequency


In this part of the article, we will discuss compatibility with regard to the size of the memory modules. The majority of kits sold in this day and age come equipped with RGB lighting, which raises the profile height. The issue that you need to check is whether or not there is sufficient room on the motherboard to support and fit these modules.

If there isn’t, then you won’t be able to use the motherboard. If not, you should look for one that has RAM modules with a low profile. In such a scenario, you might be forced to make concessions with regard to the RGB lighting, but this won’t be a problem for you because doing so will also save you money.

Best RAM for Ryzen 9 3900X – Buying Guide

It is not a simple effort to find the best RAM for your Ryzen 9 3900X, especially if you are not an expert in the field of computer hardware. The work can be made even more difficult by the fact that you are reading this. As a result, we made the decision to provide a hand. However, we’ve put in a lot of effort to compile a list of some of the greatest random access memories (RAMs) for you, which you might think about using for your gaming computer.

However, before purchasing this RAM, it is strongly advised that you have a clear understanding of the requirements and purposes for which it will be used. It will make selecting the RAM that is appropriate for your needs much simpler. In addition, we have provided a list of some essential characteristics that you need to think about before purchasing your first RAM.

1. Memory Interface Type

When you are shopping for the greatest RAM for your build, one of the most crucial things to keep in mind is the type of RAM you want to use. There are many different kinds of RAM modules available for purchase, but the DDR3, DDR4, and DDR5 varieties are currently the most common ones.

  1. DDR3 is the most affordable form of random access memory (RAM), and it has been used in personal computers (PCs) since 2009. One of the best qualities of DDR3 is that it can continue to function normally even when it is under extreme amounts of stress. The one and only drawback is that, in comparison to its other analogs, it operates at a lower frequency.
  2. DDR4 is currently the most widely used form of RAM and has established itself as the industry standard. It is both quicker and more efficient than DDR3, which it replaces. In comparison to DDR3, it possesses a higher frequency as well as lower latency timings, which enables it to operate with greater efficacy and at a higher speed.
  3. DDR5 Random Access Memory is the most recent type of RAM that has been released into the market. This type of RAM improves the overall speed and performance of your system by giving bandwidth that is up to fifty percent higher than DDR4. In addition to this, it provides double-channel memory configurations, which have double the bandwidth of DDR4 systems.

It is also possible to assert that DDR5 is the way forward for the RAM business. However, in comparison to the DDR4 equivalent, it is more expensive, but the additional expense will be well worth it.

2. Size of RAM

The quantity of data that can be stored in your computer at one time is referred to as the RAM size. When it comes to the performance of your program and the functionality of your system, having more RAM is preferable, but selecting the appropriate size of RAM is quite crucial.

The number of megabytes of random access memory (RAM) your computer needs to have depends on the types of apps you run, the number of applications you have open at once, and the amount of work your computer has to do. Having said that, I will list some of the RAM sizes that you should think about using.

  1. The most common amount of RAM is 8 gigabytes, and this amount is the one that is suggested for the majority of users since it provides sufficient performance to run a variety of apps while still providing adequate speed. It is also considered to be good when used for gaming reasons.
  2. 16 Gigabytes of Random Access Memory is the size of RAM that is recommended for those who play video games seriously because this amount of RAM is adequate for running numerous applications all at once. If, on the other hand, you just play games sometimes and you don’t have any trouble quitting applications when you’re done with them, then the 16GB RAM is the most economical and appropriate option for you to go with.
  3. There are some people who do not require as much RAM as 32 gigabytes, but if you are a strong gamer or are into video editing, streaming in 4K resolution, or multitasking, then 32 gigabytes is the ideal amount of RAM for you. In most cases, a user with typical needs will find that 16 GB of memory is sufficient to run all of the necessary apps. With 32 gigabytes of RAM, you can accomplish just about anything. If you have the extra cash to spend or if you want your personal computer to be more cutting-edge and lightning-fast, you can also select 64 gigabytes of memory to achieve the best performance your PC has ever achieved.

It is advised, however, that the larger the RAM size, the better your system will be. However, it is also true that if the size is too large and you use fewer apps, then you will be wasting your money by having a larger amount of RAM than you actually need.

3. Memory Architecture

The technique through which your RAM stores data and transfers it is referred to as its memory architecture. To put it another way, if you want faster performance, you have no choice but to go with RAM that has a more advanced memory architecture.

Memory designs come in a wide variety of forms, although the single-channel, dual-channel, and quad-channel memory architectures are by far the most common. The information that is shown here will assist you in making a decision regarding the RAM’s memory architecture.

  1. Single Channel Memory Architecture is the most affordable type of RAM; in addition to being simple to set up and difficult to corrupt in any way. Because it only has one channel, using it with a gaming computer is not advised because the performance will be very slow. If you do not have an excessive amount of RAM available on your system, then opting for 1x RAM could be a suitable choice for you.
  2. Architecture of Memory with Dual Channels A computer with a Dual Channel memory architecture is an excellent choice for a gaming rig since it improves both overall performance and stability when running resource-intensive programs like video games and video playback. It is strongly suggested that you go with dual-channel RAM if you intend to construct a computer specifically for gaming.
  3. Architecture of Memory with Four Channels A quad-channel memory architecture is the most efficient and effective memory architecture that can currently be purchased on the market. The bandwidth of a dual-channel memory architecture can be increased by this by a factor of two.

If you run high-end apps like video editing software, 4K streaming software, or video games, then this sort of RAM is another one of the greatest options available to you. Dual-channel RAMs have their advantages, but they also have certain drawbacks. Single-channel RAMs use more power, are more expensive, and produce more heat.

4. What Type of Pins does Your RAM Have (240-Pin or 288-Pin)?

Performance and productivity might be affected by the number of pins (240 or 288) that are used to connect RAM to the motherboard. This is despite the fact that RAM itself is a relatively unimportant component. The 240-pin RAM standard is the most outdated at the time of this writing; it was supported by both Intel and AMD chipsets. They are far slower than the RAM that is produced today, which is why they are now deemed to be obsolete. You should steer clear of using them.

On the other hand, if the only type of RAM that is compatible with your motherboard is 240-pin RAM, then you should go with that type. A great number of motherboards offer support for random access memories (RAM) with 240 pins. However, we strongly suggest that you go with RAMs that have 288-pins because this is the most recent generation of RAM and it provides the highest level of performance available at this time.

5. Frequency of RAM

The speed at which your system operates is determined by the frequency of the RAM in your computer; the greater the frequency, the better the performance. The frequency of RAM is determined by two factors: first, the speed at which your CPU operates, and second, the speed at which the RAM can reply to requests made by the CPU.

The bottleneck issue occurs when a user has a sluggish CPU but fast RAM; this causes the RAM to be unable to respond correctly to the demands made by the CPU. If you are using a slow CPU but fast RAM, this issue will affect you. Therefore, it is essential to have a fast central processing unit and quick random access memory (RAM), and the frequency of your RAM should also be in sync with your CPU.

When it comes to the Ryzen 9 3900X processor, it is compatible with DDR4 memory that operates at a frequency of 3200MHz. For optimal performance, it is strongly suggested that you go with a CPU that has a clock speed of 3200 MHz or above.

6. CAS Latency

When we refer to “CAS,” what we really mean is “Column Address Strobe.” The central processing unit can interface with the random access memory (RAM) thanks to this method. If a larger CAS Latency is chosen, the communication between the RAM and the CPU will proceed at a more glacial pace. If you are constructing a machine with an AIO, also known as an all-in-one liquid cooling system, then it is imperative that you select the CAS latency that is the lowest possible.

The amount of time it takes for the RAM chip in your computer to generate and send data to the motherboard is referred to as the CAS Latency. The amount of time it takes for the data stored in your RAM to be transferred to the motherboard increases in proportion to the CAS latency. As a result, we strongly advise that you select a CAS latency that falls somewhere in the range of CL12 to CL19.

7. RAM Voltage

When people talk about the voltage of RAM, they are referring to the voltage that is delivered by the motherboard (not from RAM module itself). When the voltage is increased, both the performance and the stability of the system will improve. The majority of motherboards will give 1.05V to 1.5V for two or four times the amount of RAM installed.

But if you were to ask me, what would be the appropriate voltage for RAM? Then we are going to say that 1.35V is the correct voltage for RAMs. This is because, during the course of our study, we uncovered the fact that the vast majority of RAM designed for gaming has a voltage of 1.35V, which explains why this is the case.


A computer’s processor is like its brain, and its RAM is like its spinal cord. Both work together to do computing tasks. The AMD Ryzen 9 3900x is a great 12-core, 24-thread processor that can meet the needs of gamers and content creators in the modern world.

But make sure you choose the best RAM for Ryzen 9 3900x to get the most out of the system. This post was all about this topic, and we reviewed eight top-of-the-line memory kits for a wide range of computer fans. I’m sure you would have picked one of the kits, but in case you didn’t, let me help. If you’re on a tight budget, the G.Skill Ripjaws V is a great memory kit that won’t break the bank.

People who want top-level performance, on the other hand, don’t have to think much about getting the Thermaltake Toughram RGB or the G.Skill Trident Z Royal series. All of the things above are some of my favourite suggestions. But if you’re still looking for more options, you can look at the long list of RAM above.
