The Best RAM for Ryzen 7 7800X3D
Five memory kits compared, from the Vengeance RGB to the Trident Z5 Royal Neo, with the trade-offs of each named.
By The PC Journal editorial team
12 min read5 products evaluated
The Ryzen 7 7800X3D came out with the first AM5 boards, so update the BIOS before you fit a fast kit. Every kit here is a 32GB DDR5 set with an EXPO profile and a CAS latency of 32 or lower.
Our comparison rests on published figures for CAS latency, rated speed and capacity; where a maker leaves out voltage, we say so, and no figure here comes from our own testing.

Tightest CAS Latency1 of 5
G.SKILL Trident Z5 Royal Neo 32GB (2x16GB) DDR5-6000 CL26 on Amazon (opens in a new tab)
The Trident Z5 Royal Neo runs CL26 at 6000MT/s, the tightest timings here, at 1.45V.
Best for
- Buyers who put CAS latency first.
Skip if
- Skip it if price comes first: the Vengeance RGB cost less when we checked.
Why we like it
The gain over CL30 is small on an X3D chip, so it is for enthusiasts. On CAS latency it leads this guide at CL26, ahead of the Trident Z5 Neo CL28 (CL28). Like the Trident Z5 Neo CL28 and Flare X5 32GB, it has EXPO profiles, while the FURY Beast White RGB uses EXPO and XMP profiles.
You also get a Royal-series decorative lightbar. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots.
Its 1.45V rating is higher than most kits, so check that your board lists this kit or its speed on the memory support list. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the Trident Z5 Neo CL28 and the rest.
