OWC 128GB DDR4 ECC Registered RDIMM

This 128GB DDR4 2933MHz ECC Registered RDIMM is built for Lenovo ThinkAgile servers running Xeon SP Gen 2 processors. It targets IT teams upgrading HX7521, HX7820, HX7821, VX 1U or VX2320 platforms where error-correcting registered memory is required. The module delivers 128GB capacity in a single 288-pin DIMM operating at 1.2V.

Installation notes and common issues

The DIMM slots into a standard 288-pin DDR4 socket and requires no tools beyond normal anti-static precautions. Because it is registered ECC memory it will not work in standard desktop boards and cannot be mixed with unbuffered modules. Installers must verify the server memory population rules for 4Rx4 rank configuration before adding this stick.

Registered ECC requirement decides fit

The single specification that determines compatibility is the registered ECC design with 4Rx4 organisation. Only systems qualified for registered ECC DDR4 at 2933MHz, 2666MHz, 2400MHz or 2133MHz can use this module. Buyers needing unbuffered or non-ECC memory for workstations or consumer boards cannot use this part.
