This document describes ValueRAM's KVR21E15D8K2/32I is a
kit of two 2G x 72-bit (16GB) DDR4-2133 CL15 SDRAM
(Synchronous DRAM), 2Rx8, ECC, Intel?? Compatibility Tested,
memory module, based on eighteen 1G x 8-bit FBGA
components. Total kit capacity is 32GB. 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:
