HyperX 64GB (8x8GB) 2800MHz DDR4 CL14 DIMM Memory HyperX HX428C14SBK8/64 is a kit of eight 1G x 64-bit (8GB) DDR4-2800 CL14 SDRAM (Synchronous DRAM) 2Rx8, memory modules, based on sixteen 512M x 8-bit FBGA components per module. Total kit capacity is 64GB. Each module supports Intel® XMP (Extreme Memory Profiles). Each module has been tested to run at DDR4-2800 at a low latency timing of 14-15-15 at 1.35V. The SPDs are programmed to JEDEC standard latency DDR4-2133 timing of 15-15-15 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The JEDEC standard electrical and mechanical specifications are as follows: XMP TIMING PARAMETERS JEDEC: DDR4-2133 CL15-15-15 @1.2V XMP Profile #1: DDR4-2800 CL14-15-15 @1.35V XMP Profile #2: DDR4-2666 CL14-14-14 @1.35V SPECIFICATIONS CL(IDD) 15 cycles Row Cycle Time (tRCmin) 46.5ns (min.)
