If you are planning to build/upgrade a PC with a Ryzen 9 5900X, or have already acquired it, you are probably also considering upgrading other components to make the best out of it, this means finding the best RAM for Ryzen 9 5900X.

As most gamers and tech-savvy people know, RAM is one of the most important components for an efficient machine, as not being able to access information fast enough could cause a bottleneck on your new shiny CPU.

If you are not entirely sure of which RAM to buy or want to consider other options, this post is for you. We will be looking at the best compatible RAM that you can use to squeeze every drop of performance from your Ryzen 9 5900X.

Probably the most most popular of all of these new CPUs are the Ryzen 9 5900X, a monster that offers gamers 12 cores, 24 threads support, 64MB of L3 cache,  and a base clock of 3.7 GHz that can be overclocked to 4.8 GHz.

Why is the AMD Ryzen™ 5000 Series Such a Big Deal?

2020 was a year of surprises, and it was no different for the PC gaming industry, as the long reign of Intel as king of the CPU market finally reached its end.

The history of AMD VS Intel has been the story of the tortoise VS the hare with Intel leading in most categories of benchmark testing and gamers around the world seeing AMD as the best option in terms of budget.

However, the gaming community has been witness to a progressive shift as AMD was able to start providing better performance at cheaper prices in their low and mid-end products in the last years, especially with the introduction of its Zen architecture back in 2016.

Now, with the introduction of the Zen 3 architecture with the AMD Ryzen™ 5000 Series, the red team has been able to surpass Intel when it comes to single and multi-thread processing, with all of its new CPUs providing better performance thank Intel’s flagship in most benchmark testing.

While the PC community will still need to see some more production cycles before definitely giving the crown to AMD, the red team is in the lead right now and it doesn’t seem like Intel’s upcoming Rocket Lake CPUs will be able to recover it just yet. Long live the new king!

Why is RAM Memory Important?

While it is widely known that RAM is an essential component for any computer, few people know anything about it beyond “more is better”. While this can be true in some cases, is far from absolute in most cases, with that line of thought being disastrous for power users.

If you are one of these users who just look for “DDR4 [insert number here] GB RAM”, look for your favorite or a familiar brand, buy it, and stick it in your motherboard, you will want to continue reading this section.

While there are different types of RAM, the one we will be talking about here is DIMM SDRAM, the type of RAM you are likely to install in modern desktop computers and most people are familiar with.

Not all RAM sticks are created equal in terms of specifications, but they serve the same purpose: Acting as an intermediary between your CPU’s small but fast cache and the slow but big storage drive (HDD or SDD), storing information temporarily and allowing you to run several programs at the same time by providing fast access to it.

You can think of your computer memory management as a Kitchen: the storage drive is the fridge, the CPU is your chef and cooking utensils, and the RAM is your kitchen counter.

Sure, you can store a lot of food in the fridge, but most of the time you won’t be able to immediately consume or use what you take out of it, you will need to wash it, cut it, or prepare it in some way.

Now, whoever is cooking might be able to store some food in the pots while working with it, but have you tried peeling an onion directly on the pan? Let’s not even talk about doing it in the fridge.

Here is where the kitchen counter (RAM in our analogy) comes into place, it provides temporary extra space that you can use to temporarily keep your food while providing you with a convenient place to work with it by cutting, peeling, etc.

By ensuring that you have more space, ease of access to the elements on it so you don’t have to reach far or turn around, it is clean, etc, you are sure to improve the performance of your cooking… Or in the case of your computer, processing.

Random Access Memory 101

So, you understand what RAM is and why it is important for your computer. But do you know what makes good RAM and how to choose the best option for your computer?

Terms like latency, clock speed, bandwidth, and timing are some terms that you will see when shopping for RAM, so let’s start by defining and discussing the truly relevant ones. Let’s get right into it!

Which DDR Should You Choose?

DDR stands for “Double Data Rate”, a type of RAM that gained popularity and became the default option for PC enthusiasts and manufacturers around the world.

There are different standards of DDR memories ranging from DDR1 to DDR5, which is still not mainstream as it is not fully supported/tested and manufacturers haven’t moved to it yet.

In this case, you will need to choose DDR4 as it is the only DDR supported by the Ryzen 9 5900x.

You will also need to make sure that DDR4  RAM is supported by your motherboard, so take advantage of it and also check the maximum amount of RAM it can support both in terms of slots and capacity.

Is Clock Speed Relevant?

Of course, it is!  Just as most components of your computer, RAM performance is also affected by how fast it can process data.

Higher clock speeds are better but as with most things in life, you can’t just consider a single factor. If you are choosing between higher storage capacity and higher clock speed, you will want to go for higher capacity if you are planning to use your PC for gaming or memory-intensive programs such as visual design. You should go with higher clock speeds otherwise.

You need to keep in mind that the Ryzen 9 5900x supports RAM clock speeds up to 3200MHz.

Bandwidth is Not Only Relevant to Internet Connectivity

Just like with your internet connection, RAM can benefit from having more data bandwidth that allows it to transfer more data at a given time. If clock speed is increasing the maximum speed a car can drive at on a highway, bandwidth is how many cars can drive at a given time.

The AMD Ryzen 9 5900x supports up to 2 memory channels with a max bandwidth of 47.68 GB/s, which is superb for any high-end most of the time.

An example of this is the “Latency”, which is something most unfamiliar users would look into as it sounds to be an important indicator of performance. The truth is that it is not.

The impact that latency can have on the performance of your machine can be ignored as it is practically non-existent and will always be behind capacity, bandwidth, and clock speed.

How Much Storage do You Need?

While the Ryzen 9 5900x offers support for a maximum of 128GB of RAM, this is just overkilling as most power users like gamers will be fine with just 16GB.

You can think of 16GB as the magical number for RAM, as it will allow you to run any program or game without having to worry about running out, allowing you to invest that money on other components.

However, if you are someone who is using the PC for really memory intensive purposes such as video editing, you might want to get 32 GB. This is also the case if you are thinking about building a PC that stands the pass of time without having to upgrade the RAM any time soon.

The beauty of RAM is that is one of the easiest components to replace or upgrade as time passes, letting you easily adapt if your needs change. One thing is sure, though: going over 32GB is overkill 99% of the time.

Conclusion

As you can see, there are a lot of different options when it comes to choosing the right RAM for you. It is not only a matter of capacity or performance but also of choosing the right design and price range.

One important thing to remember is that while clock speed and other factors can truly affect the performance of the RAM, the impact will be minimal in most use cases. You should make the capacity your priority over other indicators if you find yourself undecided.

Now that you know the importance of RAM and some of the things you should be looking for, decide between 16 or 23GB before taking a look at your build and imagine which of these RAMs would look better on it.

The truth is that you can’t go wrong with any of these as all of them will allow you to get every drop of performance the Ryzen 9 5900X has to offer with its new architecture and superb specifications.

Good luck and have fun!
