DESCRIPTION
Kingston FURY KF556C40BBK2-64 is a kit of two 4G x 64-bit
(32GB) DDR5-5600 CL40 SDRAM (Synchronous DRAM) 2Rx8,
memory module, based on sixteen 2G x 8-bit FBGA components per
module. Each module kit supports Intel® Extreme Memory
Profiles (Intel® XMP) 3.0. Total kit capacity is 64GB. Each
module has been tested to run at DDR5-5600 at a low latency timing
of 40-40-40 at 1.25V. The SPDs are programmed to JEDEC
standard latency DDR5-4800 timing of 40-39-39 at 1.1V.
Each 288-pin DIMM uses gold contact fingers.
