Kingston Server Premier 8GB PC4 DDR4-2666MHz 1Rx8 UDIMM Unbuffered ECC Memory

Description

Overview

Kingston’s KSM26ES8/8HD is a 1G x 72-bit (8GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1Rx8, ECC, memory module, based on nine 1G x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2666 timing of 19-19-19 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
