Memory Module Specifications 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: SPECIFICATIONS CL(IDD) 15 cycles Row Cycle Time (tRCmin) 47.05ns(min.) Refresh to Active/Refresh Command Time 1x mode (tRFCmin) 260ns(min.) Row Active Time (tRASmin) 33.00ns(min.)
