Best RAM For Ryzen CPUs (Buying Guide) in 2021

Finding the best RAM for Ryzen CPUs may not be easy if you don’t know what to look for, but fortunately we have you covered. While Ryzen CPUs are notoriously more dependent on having great RAM than Intel CPUs, ensuring that you have great RAM with your Ryzen CPU will enable the industry-leading multi-core performance that these chips are known for in comparison to their Intel counterparts.

Don’t know a whole lot about RAM and etc? Don’t worry- we’ve narrowed down the best RAM for Ryzen CPUs for you to choose from, and written a detailed buying guide to help you make an informed purchase.

Best RAM for Ryzen CPUs

Best RAM For Ryzen CPUs

We’ve done the research so you don’t have to; this is our list with the best RAMP for AMD Ryzen processors.


Capacity: 16 GB | Speed: 3000 MHz | CAS: 16 | Configuration: 2×8 GB (Dual Channel)

  • Fairly cheap for speed/capacity
  • Low CAS latency
  • White heatsink should work well with most PC builds

XPG 16GB (2 x 8GB) GAMMIX D30 DDR4 PC4-24000 3000MHz Desktop Memory

Just want to get some good Ryzen RAM and aren’t too fussed about what you get as long as it works well and doesn’t break the bank?

The ADATA XPG GAMMIX D30 Kit is our ideal pick for you. It’s one of the cheapest available RAM kits that meet all of our minimum specifications for good Ryzen RAM. Low CAS Latency, a 3000 MHz speed, and a Dual-Channel configuration all at a fairly good price. There aren’t any real downsides here, unless you don’t like the look of the white heatsink on the RAM itself.

This pick not available? Get the ADATA XPG Z1 instead, which has the same specs but a red heatsink.

Verdict: Best Budget RAM For Ryzen

#2. G.Skill Ripjaws V (16GB Kit)

Capacity: 16 GB | Speed: 3600 MHz | CAS: 18 | Configuration: 2×8 GB (Dual Channel)

  • Fairly fast, shouldn’t bottleneck any Ryzen 5 or Ryzen 7 CPU in games or other workloads
  • Black heatsink should work well with most PC builds
  • Slightly higher CAS, though this is offput by speed increase
  • Slightly higher price than other options

G.Skill RipJaws V Series 16GB (2 x 8GB) 288-Pin SDRAM PC4-28800 DDR4 RAM for Ryzen

If you want something a little better than “just good enough”, then we highly recommend this G.Skill Ripjaws V Kit.

While the CAS latency has slightly increased to 18, the speed increase to 3600 MHz more than makes up for that in actual performance. The black heatsink should also allow this RAM to go well with just about any PC build you slap it into- no jarring primary colors here!

Additionally, while the price is slightly higher than our other option, it really only is slightly higher (about ten dollars at the time of writing, though this will vary over time).

This is the pick that we would recommend to most gamers who are using Ryzen CPUs- improvements can surely be made, but for practical gaming purposes this should be all you need.

Verdict: Best RAM For Ryzen Gaming

#3. G.Skill Ripjaws V (CL16 16GB Kit)

Capacity: 16 GB | Speed: 3600 MHz | CAS: 16 | Configuration: 2×8 GB (Dual Channel)

  • High speed
  • Low CAS latency
  • Black heatsink should blend with the majority of PC builds
  • High price
  • Sometimes-limited availability

G.Skill RipJaws V Series 16GB (2 x 8GB) 288-Pin SDRAM PC4-28800 DDR4 3600 CL16

If you want great RAM for Ryzen with as few compromises as possible, then this Ripjaws V kit is the one you’re looking for. It’s a lot like the one listed just above, but with a few key differences: most namely, it accomplishes the speed boost to 3600 MHz without increasing the CAS latency from 16. The other key points still stand- black heatsink that works with just about any build, perfect for gaming and other heavy applications, etc.

However, this no compromises pick does come with a few downsides of its own- namely a higher price and lower availability.

Verdict: Best RAM For Ryzen (No Compromises Pick)

#4. G.Skill Trident Z RGB

Capacity: 32 GB | Speed: 3600 MHz | CAS: 16 | Configuration: 2×16 GB (Dual Channel)

  • Great speed without sacrificing CAS latency
  • High capacity
  • RGB!
  • Fairly high price

G.SKILL 32GB (2 x 16GB) TridentZ RGB Series DDR4 PC4-28800 3600

Last but certainly not least is our RGB/32GB pick!

The G.Skill Trident Z RGB kit has all the specs you’ve come to expect out of good Ryzen RAM by now- 3600 MHz at a squeaky-clean 16 CAS latency. Slap some RGB onto it and double the capacity up to 32 GB and congratulations: you got yourself a high-end memory set up that should work perfectly with your Ryzen 7 or Ryzen 9 CPU!

With those improvements (especially the RGB), however, comes a cost. A very literal cost- this is the most expensive option on this list by a considerable margin. If that isn’t an issue, though- especially if you’re shopping for 32 GB RAM kits- then we wholeheartedly recommend this.

Want a 32 GB Kit for a bit cheaper and don’t care about RGB? Get this 32 GB Ripjaws V Kit instead- it has the same specs.

Verdict: Best RAM For Ryzen with RGB

All You Need To Know About Ryzen RAM

Read through our reviews and still not sure what to pick, or skipped down here to learn the need-to-know info for an informed buying decision? Either way, we have you covered! 

Why does AMD Ryzen require different RAM compared to Intel Core processors?

Infinity Fabric.

To specify, Infinity Fabric is a memory management technology in AMD CPUs and GPUs. The Infinity Fabric in an AMD CPU is what connects every part of the CPU to every other part of the CPU, and even some connections to the board and chipset. This Infinity Fabric is a key part of what makes Ryzen processors so good at handling multi-threaded workloads, and its performance can be both positively and negatively impacted by the RAM that you choose to pair it with.

What makes RAM good for Ryzen?

Infinity Fabric, but also the manufacturing process.

There are a few different ways to evaluate what kind of RAM will be good for Ryzen CPUs.

The usual points of RAM-buying advice remain true:

  • Speed – Higher is better
  • CAS Latency – Lower is better
  • Capacity – More is better

There are a few other factors to take into account as well. If we had written this guide a few years earlier, we would have spoken at length about Samsung B-Dies here. Samsung B-Dies were included in particular RAM kits and enabled even better performance with Ryzen CPUs, though only by small (5 percent or less) margins. Seeing as these are no longer being manufactured as of 2020 and this article is being penned in 2021, we aren’t going to be including B-Die picks in this article- though with some of the higher-end options you may Happy Accident your way into one anyway.

Why does Configuration (Dual-Channel, Quad-Channel, etc) matter, and what is it?

When you install RAM onto your motherboard, you have a few different options depending on the number of available RAM slots and RAM sticks. The size of your motherboard has a big impact on this.

  • 1 Slot Full / Any Size – Single Channel
  • 2 Slots Full / Mini ITX – Dual Channel
  • 4/8 Slots Full / Micro ATX & ATX – Quad Channel

When your RAM is running in Single Channel, that means you have only a single RAM stick active in your system. Single Channel RAM is limited to half of its rated speed due to the way that DDR (Double Data Rate) functions.

DDR RAM is functioning as intended when you have two identical RAM sticks running in a Dual Channel configuration. This allows the RAM to reach it’s full rated speeds by synchronizing with another, identical chip.

Quad Channel further improves upon this, but only marginally- for instance, speed does not double again. It’s DDR, not QDR.

In general, Dual Channel offers the greatest performance improvement, where Quad Channel only provides marginal gains in specific high-end workloads. We always recommend Dual Channel or better when buying RAM for your system.

What capacity is right for me?

RAM capacity is pretty straightforward, fortunately. We’ll just break it down below for you.

  • Non-heavy web browsing and light productivity/gaming  = 4 GB
  • Modern gaming and regular productivity/heavy browsing (10+ tabs in 2+ windows) = 8 GB
  • Heavy productivity/gaming or extreme web browsing (10+ tabs in 3+ windows) = 16 GB
  • Extreme heavy productivity (ie virtualization, (game)servers, and etc) = 32+ GB
  • Enterprise productivity = 128+ GB, to scale with needs

What speed is right for me?

RAM speed impacts Ryzen CPUs a good bit more than it impacts Intel CPUs due to the aforementioned Infinity Fabric. In general, though, we recommend aiming for 3000 MHz as a baseline for good performance with Ryzen CPUs. Higher is still better, but past the 3000 MHz range the improvements will seem fairly marginal for most users, if they can be seen at all. We don’t recommend going below 3000 MHz, though, as this will cause you to lose at least a little bit of performance.
