This document describes ValueRAM's KVR21N15S8/8 is a 1G x 64-bit (8GB) DDR4-2133 CL15 SDRAM (Synchronous DRAM), 1Rx8, memory module, based on eight 1G 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.
