DESCRIPTION

HyperX HX437C19FB3A/8 is a 1G x 64-bit (8GB) DDR4-3733 CL19

SDRAM (Synchronous DRAM) 1Rx8, memory module, based on

eight 1G x 8-bit FBGA components per module. Each module kit

supports Intel® Extreme Memory Profiles (Intel® XMP) 2.0. Each

module has been tested to run at DDR4-3733 at a low latency timing

of 19-23-23 at 1.35V. The SPDs are programmed to JEDEC

standard latency DDR4-2400 timing of 17-17-17 at 1.2V. Each

288-pin DIMM uses gold contact fingers. The JEDEC standard

electrical and mechanical specifications are as follows:
