Kingston KF556C40-16 16GB Review
Kingston KF556C40-16 is a 16GB DDR5-5600 CL40 FURY Beast Black desktop memory module.
A widely-available 16GB single stick at DDR5-5600 CL40, FURY Beast's mainstream mid-tier speed grade for a straightforward desktop capacity upgrade.
Performance
DDR5-5600 CL40 is FURY Beast's mainstream mid-tier speed grade, a step above JEDEC baseline without paying for the tightest available timings.
Compatibility
Standard non-ECC desktop UDIMM, black heatspreader, no RGB. Runs in any DDR5 desktop board at DDR5-5600.
Comparison to Alternatives
Against the Kingston FURY Beast KF556C36-8 or KF556C36-32 (same DDR5-5600, tighter CL36) also in this catalog, those parts offer lower latency at a similar price per GB. Against the Kingston ValueRAM HP56S46BS8HA-16 (DDR5-5600 CL46) also in this catalog, this FURY Beast part has a meaningfully tighter documented CL40 timing and a heatspreader.
