Overview

The Lenovo ThinkSystem 16GB 1Rx8 DDR5-4800 RDIMM, part number 4X77A81437, is an entry-size DDR5 module for AMD-based ThinkSystem servers. It is listed for the SR645 V3 and SR635 V3.

It has ECC and a 4800 MT/s data rate. A single-rank layout with x8 chips keeps the module simple, and 16GB is a sensible starting capacity when you populate many channels for bandwidth rather than for sheer capacity.

Buyers pick this module to equip a new V3 server, to extend memory on an existing one, or to replace a failed DIMM. Keep module type and speed consistent across a channel, and follow the server's population guide.

The module is available new or refurbished, each with a choice of 1 year or 3 years of warranty. No used offer is listed. Add 4X77A81437 to your RFQ and specify the SR645 V3 or SR635 V3 it is for.
