Overview

The A in RDIMM-A is part of Lenovo's data for this module, and it points to the group of servers the memory is documented for. The Lenovo ThinkSystem 4X77A81438 is a 32GB 1Rx4 RDIMM-A running DDR5 at 4800MT/s with ECC. Voltage is not listed.

The compatible systems are the ThinkSystem SR645 V3, SR665 V3, SR635 V3 and SR655 V3, plus the Lenovo ThinkEdge SE455 V3 and SE455i V3. The feature code is BQ39. Plain RDIMM versions without the A suffix are separate part numbers, so match the variant to your platform.

A 32GB module is a sound base for single-socket and dual-socket AMD-based servers alike.

We can supply it new or refurbished with 1 year or 3 years of warranty, or used with 90 days. Tell us your server model and the quantity needed and we will reply with pricing and availability.
