Overview

A single-rank 32GB module for two-socket AMD servers, the Lenovo ThinkSystem 4X77B09790 is an RDIMM-A marked v2, written 1Rx4 and rated at DDR5 6400MT/s with ECC.

Lenovo lists it for the SR645 V3 and SR665 V3, with feature code CBNB. Because single-rank modules load a channel less than dual-rank ones, they can help when a build wants two modules per channel without a large speed drop, though your processor's rules decide the final number.

It is a straightforward capacity module for virtualization hosts and general application servers that need 32GB per slot.

Only new and refurbished offers are listed, each with a choice of 1 year or 3 years of warranty. A used unit is not offered. Send us the quantity and the server model and we will reply with pricing and availability.
