Server memory upgrade

This 32GB DDR4 2933MHz CL21 registered ECC RDIMM is built for Supermicro X11SP series motherboards. It runs at 1.2V with a 2Rx4 rank configuration and includes no heat spreader.

Workstation and server builds

Suits administrators expanding Supermicro X11SPi-TF, X11SPL-F, X11SPM-F, X11SPM-TF or X11SPM-TPF platforms. Not for standard desktop PCs and cannot be mixed with unbuffered memory modules.

Build integration

Fits 288-pin DDR4 slots and operates at 2933MHz with backward compatibility to 2133MHz, 2400MHz and 2666MHz speeds. Frees DIMM slots by delivering 32GB in a single registered module.

Questions about this item

Which motherboard must I already have to install this 288-pin DDR4 2933MHz ECC RDIMM?

It is validated for Supermicro X11SPi-TF, X11SPL-F, X11SPM-F, X11SPM-TF and X11SPM-TPF motherboards.

Can I keep my existing 2133MHz, 2400MHz or 2666MHz DDR4 modules and add this 32GB CL21 kit?

Yes, the module is backward compatible with those speeds, but all installed DIMMs must be ECC registered; mixing with unbuffered memory is not supported.

How do I confirm the 32GB module is running at 2933MHz with ECC active after installation?

Check the BIOS memory information or run a hardware utility such as dmidecode; it should report 2933MHz, CL21, 1.2V and ECC registered status.
