Lenovo ThinkSystem 64GB DDR5 6400MT/s 2Rx4 RDIMM-A v2

This Lenovo ThinkSystem module, MPN 4X77B09643, is a 64GB 2Rx4 RDIMM-A marked v2, rated at DDR5 6400MT/s with ECC.

Its compatibility entry is short: Lenovo lists this module for the SR635 V3 and SR655 V3, the single-socket AMD-based ThinkSystem servers. The feature code is CBFR. If you run either of those machines and want a large module, the entry is a direct match.

Single-socket platforms rely on a high-capacity module to reach a big total, since they have half the slots of a two-socket system. Sixty-four gigabytes per DIMM is a common way to give one of these servers plenty of room.
