The nearest checked memory kits by key specifications, with what differs from the Kingston FURY Beast 16 GB. The first matches the Compare button above.

The checks that matter.

Before you buy

The programmed JEDEC default is 4800 MT/s at 1.1 V; the rated 5200 MT/s profile needs 1.25 V and compatible CPU, motherboard and BIOS support. The source gives three timing components rather than a complete four-part tuple. Check cooler clearance for the 34.9 mm modules; AMD EXPO support remains unverified.
