The right memory kit starts with your board: DDR5 for AM5, Core Ultra and most new Intel builds, DDR4 for AM4 and older Intel boards.

We compared six kits across both types. This is a research-based comparison built from maker specifications and retailer listings; we did not test these parts ourselves.

Skip it if price comes first: the Vengeance LPX 32GB cost less when we checked.
Kingston FURY Beast 32GB (2x16GB) DDR5-6000 CL30

Why we like it

On CAS latency it ties with the Bolt V at CL30. On rated speed it ties with the Bolt V, the Crucial Pro 6000 and the Flare X5 CL36 at 6000MT/s. It matches the Bolt V, the Crucial Pro 6000, the Flare X5 CL36 and the Vengeance LPX 32GB on capacity (32GB (2 sticks)).

Why we like it

On CAS latency it sits mid-pack at CL32: the Vengeance LPX 32GB offers CL16, and the Flare X5 CL36 comes in at CL36. On rated speed it leads this guide at 6400MT/s, ahead of the FURY Beast (6000MT/s). Nothing else here matches its 64GB (2 sticks) capacity; the FURY Beast comes closest at 32GB (2 sticks).

No other pick in this guide offers EXPO profiles; compare the Vengeance LPX 32GB, which has XMP 2.0 profiles. It also offers a plain heatspreader. 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. It was the highest-priced of the 6 picks at the time of writing, so the case for it rests on what it adds over the FURY Beast and the rest.

How these picks were ranked
We set side by side six kits on CAS latency, rated speed, capacity and voltage from manufacturer specifications. We did not test them in-house, and voltage and low profile are missing for at least one pick.
The shared baseline
All 6, from the FURY Beast to the Vengeance LPX 32GB, state CAS latency, rated speed and capacity.
Where the specs have gaps
The FURY Beast, the Crucial Pro 6000 and the FURY Beast 64GB give no voltage; the Bolt V, the Crucial Pro 6000 and the FURY Beast 64GB give no low profile.
Price range
At our last check the picks ran from the Vengeance LPX 32GB ($150 to $250) to the FURY Beast 64GB ($1000 to $1500).
