AMD’s latest and greatest flagship processor, the Ryzen 9 3900X and 3900XT (along with the Ryzen 9 3950X which was released in November 2019) has made some amazing progress to dethrone some of the best CPUs from Intel (hello 10900K).
That being said, if you are building a new gaming PC and at its heart, you have the Ryzen 9 3900X or 3950X or 3900XT, then the thing that you need to know is that 9-series CPUs work really well with RAM that is high speed.
Based on my testing the best RAM speed for a Ryzen 9 is 4400 Mhz. The best memory I tested was the Patriot Viper Steel 4400 Mhz 16GB Kit. This was with an X570 motherboard, with NVME M.2 SSD (Samsung 970 Evo Plus) on Windows 10 and a new AMD Ryzen 9 3900XT.

This is actually something that is consistent throughout all the generation of Ryzen processors; most of them can really benefit from higher speed RAM. This is especially true for the Ryzen 9-series CPUs.
The recommended RAM or memory speed for Ryzen 9’s is 3600 Mhz. If you are on more of a budget (why are you on a budget with a Ryzen 9? lol), a 3200 Mhz ram kit from Corsair is a great pairing.
Best Overall RAM for Ryzen 9 3900X or 3900XT or 3950X: Patriot Viper Gaming 4400 Mhz
This 16-GB kit from Patriot was the best performing RAM by far, across multiple benchmarks and real-world gaming testing. It had the highest FPS for gaming in Overwatch and solid benchmark scores in RealBench and UserBench.
Here’s the benchmark dataset from my testing. CPU used was a Ryzen 9 3900XT, X570 Aorus Ultra Gaming Motherboard, 250GB SSD Samsung 970 EVO Plus.

That being said, we have decided to list down a few other picks for a best RAM for Ryzen 9 3900XT or 3950X. In order to keep this simple and straightforward for the readers, we have refrained from including too many options. Therefore, this list is going to be short and concise.
Corsair Dominator Platinum 32GB
Best RAM For Ryzen 9 3900X And 3950X Overall
I still remember the day when G.Skill came out with the Trident Z line up of RAM kits. The world was taken by a storm because these RAM kits were amazing in every single aspect.
They not only looked amazing, but they had insanely good performance, too. Over time, they released a lot of different colour options in the RAM, as well as the much famous Trident Z RGB that took the market by storm.
However, today, we are looking at their newly released Trident Z Neo; this RAM kit only came out a month ago, and the best part about this RAM kit is that it is made specifically for Ryzen CPUs. So, for anyone who is building a new system and is in need of some great looking RAM, this is the way to go. The performance, on the other hand, is also a great aspect.
To start with the good things, the RAM is great thanks to its low latency timings and higher frequency speed at 3,600 MHz out of the box. This is great because as we discussed, all Ryzen processors do benefit from higher speeds, so you are definitely getting something out of the market.
Another great thing about this RAM is that at the price you are paying for this kit, you are getting the legendary quality that G.Skill is known for and not to mention, the gorgeous looks with the RGB. I still believe that the RAM has one of the best RGB implementations that we could think of.
On the flip side, I will be honest, I did not really find any issue with the RAM that could come in the way. G.Skill has made sure that the RAM does give a stellar performance and that it does through and through.
In conclusion, we have to admit that G.Skill has scored a home run when you are looking at the Trident Z Neo. The RAM is one of the best available in the market you can pair with 3900X and 3950X, and the best part is that you are going to get great performance out of it, too. If you are looking for something good and something over the top, this is the way to go and I can assure you that you will not run into any issues that might come in the way, either.
Pros
- Top of the line performance.
- Low latency.
- Great speeds out of the box.
- Very competitively priced.
- Gorgeous looks.
Cons
- None

Conclusion
The Ryzen 9 3900X / 3950X are still relatively new, but they’re achieving mainstream success really fast.
If you are building a Ryzen based gaming system and you want to make sure that there is no performance disparity or discrepancy involved in the process, then choosing one of these RAM kits is the right thing to do.

Best non-RGB 3600 Mhz RAM For Ryzen 9 3900X And 3950X or 3900XT
I love Corsair Ram. It always just works. AMD recommends 3600Mhz for its Ryzen 9 series, so this speed option is a great pick. It’s not my “best” speed pick, because I like overclocking to 4400 Mhz, but this is still a very fast speed.
There is no denying that Corsair has never been shy to bring out some really amazing products into the market. The best thing about the company is that they have something for everyone.
So, if you are not looking to spend all your money on a RAM kit, you can actually buy one of their cheaper options and make do with that, too. Since Corsair does give you the liberty to do so.
With that said, however, the RAM kit we are looking at today is the Corsair Dominator Platinum 32GB; one of the highest-end RAM kits that Corsair is currently selling and for all the right reasons. The great thing about this RAM is it has phenomenal speeds through and through.
While you might not benefit from these if you are on Intel, if you are running the Ryzen 9 3900X or XT, you are going to love these. Another great thing is that when you do turn on the XMP profile, you get a stellar boost in performance that is both noticeable and stable, too.
You can actually tweak the RAM to your heart’s content because the RAM is really good when it comes to tweaking. Oh, and if you are looking for something a bit better looking, you can invest in the RGB version of this RAM, too.
On the contrary, there is not a lot about this RAM that one would not like. In our testing, the RAM worked perfectly fine under all conditions and scored impressive results. We have to say that the Ryzen 9 3900X takes a lot of benefit from the higher frequency, and works like a treat.
Overall, I will say that the Corsair Dominator Platinum 32GB is definitely one of the best DDR4 RAMs that you can buy for your Ryzen 9 3900X. Granted, it is on the expensive end, but the good thing is that the performance n this RAM is just too good.
Pros
- Excellent performance.
- Great XMP profile.
- Overclocks like a champion.
- Looks great.
Cons
None.
