Lenovo ThinkSystem 128GB 4Rx4 DDR4-2933 3DS RDIMM TruDDR4 Memory

The Lenovo ThinkSystem 4ZC7A15113 is a 128GB 3DS RDIMM, which means stacked memory chips on a registered module with four ranks of x4 devices. It has ECC, runs at 1.2V and has a 2933 MT/s data rate.

It is listed for the ThinkSystem SR650 with Xeon SP Gen 1 or Gen 2. Check which processor generation your server uses, since it affects the memory speed the platform can run.

Modules this large are for servers where RAM is the constraint: big virtualization hosts, in-memory databases and analytics. Four ranks per module also means channel rank limits matter, so consult the server's memory guide before planning how many to install.

It is part of Lenovo's TruDDR4 line and can replace a failed module of the same type.

The module is offered refurbished with 1 year or 3 years of warranty, and used with a 90 day warranty. No new offer is listed. Submit an RFQ for 4ZC7A15113 with the count and your SR650 details.
