This document describes ValueRAM's 1G x 72-bit (8GB)
DDR4-2133 CL15 SDRAM (Synchronous DRAM), 2Rx8, ECC,
memory module, based on eighteen 512M x 8-bit FBGA
components. The SPD is programmed to JEDEC standard
latency DDR4-2133 timing of 15-15-15 at 1.2V. This 260-pin
DIMM uses gold contact fingers. The electrical and mechanical
specifications are as follows:
