KVR21R15S8/4
4GB 1Rx8 512M x 72-Bit PC4-2133
CL15 Registered w/Parity 288-Pin DIMM
DESCRIPTION
ValueRAM's KVR21R15S8/4 is a 512M x 72-bit (4GB)
DDR4-2133 CL15 SDRAM (Synchronous DRAM) registered w/
parity, 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:
