HyperX HX428C14SB2K8/64 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 14-17-17 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.
