KVR21R15D4K4/128
128GB (32GB 2Rx4 4G x 72-Bit x 4 pcs.) PC4-2133
CL15 Registered w/Parity 288-Pin DIMM Kit
Description
ValueRAM's KVR21R15D4K4/128 is a kit of four 4G x 72-bit (32GB) DDR4-2133 CL15 SDRAM (Synchronous DRAM) registered w/ parity, 2Rx4, ECC, memory module, based on thirty-six 2G x 4-bit FBGA components per module. Total kit capacity is 128GB. 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:
