Kingston KF552C40-8 8GB Review
Kingston KF552C40-8 is an 8GB DDR5-5200 CL40 FURY Beast Black desktop memory module.
An entry-speed 8GB single stick at DDR5-5200 CL40, priced for a light capacity top-up rather than a high-bandwidth build.
Performance
DDR5-5200 CL40 sits just above JEDEC baseline speeds, a modest step up that's easy on the wallet for buyers not chasing bandwidth.
Compatibility
Standard non-ECC desktop UDIMM, black heatspreader, no RGB. Runs in any DDR5 desktop board at DDR5-5200.
Comparison to Alternatives
Against the Kingston FURY Beast KF556C40-8 (DDR5-5600 CL40) also in this catalog, that part runs faster at a similar CAS latency for a small price step up. Against the Kingston FURY Beast XF1R8M-HYM-A OEM part (32GB, same 5200/CL40 grade) also in this catalog, this is the smaller-capacity retail-boxed equivalent.
