DESCRIPTION
Kingston FURY KF556C40BBAK2-64 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. The JEDEC 
standard electrical and mechanical specifications are as 
follows:
