Lenovo ThinkSystem 64GB 4Rx4 DDR4-2666 LRDIMM TruDDR4 Memory

The Lenovo ThinkSystem 7X77A01305 is a 64GB LRDIMM, a load-reduced module with four ranks of x4 chips. It has ECC, runs at 1.2V and has a 2666 MT/s data rate. It is listed for the ThinkSystem SR650 with Xeon SP Gen 1 or Gen 2.

Load-reduced modules buffer data lines, which lets a server handle more ranks per channel than registered modules allow. They are chosen for large memory totals. A server using LRDIMMs should generally hold only LRDIMMs, so check what is installed before you order.

Typical buyers run virtualization or database servers where memory capacity limits consolidation. The module is also a like-for-like replacement for a failed LRDIMM.

Confirm which processor generation your SR650 uses, and read the memory guide for population limits.

The module is offered refurbished with a choice of 1 year or 3 years of warranty, and used with a 90 day warranty. No new offer is listed. List 7X77A01305 on an RFQ and confirm that your server is built on load-reduced memory.
