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.

Our Picks

G.SKILL Trident Z5 Royal Neo 32GB (2x16GB) DDR5-6000 CL26

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.

The label rests on the tightest CAS latency here (CL26). The Trident Z5 Neo CL28 is next on CAS latency at CL28, so this pick's CL26 is 7% further out. It is aimed at anyone who puts CAS latency first.

Do the Trident Z5 Royal Neo and the Trident Z5 Neo CL28 differ on voltage?

The Trident Z5 Royal Neo uses 1.45V; the Trident Z5 Neo CL28 and the Vengeance RGB use 1.4V; the Flare X5 32GB uses 1.35V. The maker of the FURY Beast White RGB doesn't state voltage, so 4 of 5 picks are covered here.

Beyond the specs, what sets the Trident Z5 Royal Neo and the Trident Z5 Neo CL28 apart?

The Trident Z5 Royal Neo: timings of 26-36-36-96. The Trident Z5 Neo CL28: timings of 28-36-36-96. The FURY Beast White RGB: Kingston's infrared RGB syncing.

Bottom Line

Our first pick is the Trident Z5 Royal Neo, chosen for the tightest CAS latency here (CL26). Look at the Trident Z5 Neo CL28 for timings of 28-36-36-96, the FURY Beast White RGB for Kingston's infrared RGB syncing and the Flare X5 32GB for a 1.35V rating, the lowest here if those matter more to you.

If the system will not boot at the rated speed, update the BIOS first and then re-enable EXPO.
