Overview

The Lenovo ThinkSystem 4X77A88639 is a 48GB single-rank RDIMM written 1Rx4, running DDR5 at 5600MT/s with ECC.

It is documented for just two systems, the ThinkSystem SR630 V3 and SR650 V3, with feature code BX8Y. The narrow list makes it a clear fit if you run either of those rack servers and want a 48GB module at the faster 5600 rate.

Single-rank modules put less electrical load on a channel than dual-rank ones. In some configurations that helps hold the rated speed with two modules per channel, but check the processor's supported speeds rather than assuming it.

Only new and refurbished offers are listed, each with a choice of 1 year or 3 years of warranty. Tell us your server model and the number of modules and we will reply with pricing and availability.
