AMD's new Ryzen 9000 processors are here, but these AMD5 CPUs aren't compatible with last-gen DDR4 memory. That means that if you're building or upgrading a PC and have chosen the Ryzen 9 9900X for your CPU, it might be time for a RAM upgrade. We don't want you to settle for something sub-par with a chip like this. Below, we've rounded up the best RAM for the Ryzen 9 9900X to help you get the most out of AMD's snappy new "Zen 5" hardware.

It's not the cheapest, but the G.Skill Trident Z5 Neo RAM kit has everything we want for the Ryzen 9 9900X build. It offers an impressive clock speed of 6000MT/s with a CAS latency of 30, which is great for DDR5, and its RGB accent looks good for a gaming build without being too flashy.

Best value
TEAMGROUP Elite DDR5-4800 (2x16) RAM
RAM is pretty simple hardware, and you don't need to spend a small fortune to get something that's "good enough." The Teamgroup Elite DDR5 RAM is a solid, no-frills memory kit that's easy on the wallet, offering 4800MHz speeds. The 40 CAS latency isn't the best, but the price is hard to argue with.

Premium pick
Corsair Dominator Titanium RGB DDR5 64GB (4x16GB) 6400 CL32
The Corsair Dominator Titanium RGB DDR5 RAM is the memory kit to buy for a high-end build. It combines great style (in black or white to suit your PC's aesthetic) with excellent performance, featuring a 6400MHz clock speed and CL32 latency. Just make sure your case has room for its tall-standing design!
-
Best RGB styling
Corsair Vengeance Pro RGB DDR5 RAM
It's a little more expensive than our top pick, but the Corsair Vengeance Pro oozes RGB style without skimping on performance. It offers the same 6000MHz speeds and low 30 CAS latency as the G.Skill Trident Z5 but sports a customizable ten-zone RGB light bar across the entire stick length, adding some extra flair to your build.

The ADATA XPG Lancer RAM is one of the best DDR5 memory sticks you can buy, and the ROG variant is the best kit for a gaming build.

Tight on space? This non-RGB variant of the Corsair Vengeance DDR5 loses the light bar for a more compact, lower-profile stick size that's a good fit for builds with limited RAM clearance due to a smaller case or large GPU getting in the way.

If you're looking for RAM sticks that match a white case, but our premium pick was too pricey, the Teamgroup T-Force Delta DDR5 kit should scratch that itch.

Which RAM kit is best for the AMD Ryzen 9 9900X?
The Ryzen 9 9900X is a powerful 12-core processor that's purpose-made for gaming and productivity, but you already know that if you've been following the best AMD CPUs. Newer AM5 processors like the Ryzen 9 9900X aren't compatible with last-gen DDR4 RAM, but you shouldn't be cutting corners with mediocre RAM for this CPU anyway. When rounding up the best RAM for the Ryzen 9 9900X, we included dual-channel kits offering high clock speeds and reasonably low latency to help you get the most performance out of your CPU.
Our top recommendation is the G.Skill Trident Z5 Neo. This DDR5 RAM is optimized for AMD Expo, making it a good fit for the new "Zen 5" chips, and has a clock speed of 6000MT/s with a CAS latency of 30. That's great performance for its price. If you'd prefer something without RGB, our runner-up, the G.Skill Flare F5, delivers virtually identical performance with a more understated style.
Just need some good, cheap RAM for your Ryzen 9 9900X build? You can't go wrong with the Teamgroup Elite DDR5 RAM, which, despite its low price, still boasts a clock speed of 5600Mhz. But that won't do if you're putting together a high-end gaming PC build. You should instead spring for our premium pick, the Corsair Dominator. This DDR5 RAM offers a very responsive 6400MHz clock speed and CAS latency of 32, and it looks incredible with subtle RGB accents. It's also available in black or white, making it a good fit for any aesthetic.
