KVR21E15S8/44GB 1Rx8 512M x 72-Bit PC4-2133
CL15 288-Pin DIMM
DESCRIPTIONThis document describes ValueRAM's KVR21E15S8/4 is a 512M x 72-bit (4GB) DDR4-2133 CL15 SDRAM (Synchronous DRAM), 1Rx8, ECC, memory module, based on nine 512M x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2133 timing of 15-15-15 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
FeaturesPower Supply: VDD=1.2V Typical
