KVR21N15D8/8 8GB 2Rx8 1G x 64-Bit PC4-2133 CL15 288-Pin DIMM

FEATURES

This document describes ValueRAM's KVR21N15D8/8 is a 1G x 64-bit

(8GB) DDR4-2133 CL15 SDRAM (Synchronous DRAM), 2Rx8,

memory module, based on sixteen 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:
