16GB 2Rx8 2G x 64-Bit PC4-2133
CL15 260-Pin SODIMM
DESCRIPTION
This document describes ValueRAM's 2G x 64-bit (16GB)
DDR4-2133 CL15 SDRAM (Synchronous DRAM), 2Rx8, non-ECC,
memory module, based on sixteen 1G 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:
