This document describes ValueRAM's 512M x 64-bit (4GB) 

DDR4-2133 CL15 SDRAM (Synchronous DRAM), 1Rx8, 

memory module, based on eight 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:
