ValueRAMs 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 onthirty-six 2G x 4-bit FBGA components per module. Total kitcapacity is 128GB. The SPD is programmed to JEDEC standardlatency DDR4-2133 timing of 15-15-15 at 1.2V. Each 288-pinDIMM uses gold contact fingers. The electrical and mechanicalspecifications are as follows:
