FEATURES
This document describes ValueRAM's KVR21E15D8/16 is a 2G x
72-bit (16GB) DDR4-2133 CL15 SDRAM (Synchronous DRAM),
2Rx8, ECC, memory module, based on eighteen 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.

 The electrical and mechanical specifications
