Server memory upgrade

This 32GB OWC DDR4 2933 CL21 ECC RDIMM is built for Supermicro X11SPA-TF, X11SPD-F, X11SPG-TF, X11SPH-nCTF and X11SPH-nCTPF motherboards. It runs at 1.2V with a 2Rx4 rank layout and no heat spreader. The registered design adds signal integrity for multi-DIMM server configurations.

Suits ECC servers only

This module fits workstations, servers and NAS systems that require registered ECC DDR4. It will not work in standard desktop boards that accept only unbuffered memory. Mixing it with unbuffered DIMMs is not supported. Buyers needing non-ECC or unbuffered memory should look elsewhere.

Registered ECC decides fit

The single specification that determines compatibility is the registered ECC RDIMM form factor. Your motherboard must explicitly support registered ECC DDR4 at 288 pins. If the platform requires unbuffered or non-ECC modules, this part will not function.

Questions about this item

What motherboard must I already have to install this 288‑pin DDR4 2933 ECC RDIMM?

It is validated for Supermicro X11SPA‑TF, X11SPD‑F, X11SPG‑TF, X11SPH‑nCTF and X11SPH‑nCTPF boards.

Can I keep my existing 2133 MHz or 2400 MHz DDR4 modules and add this 2933 MHz kit?

Yes, the module is backward compatible with 2133 MHz, 2400 MHz and 2666 MHz speeds, but it cannot be mixed with unbuffered memory.

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

Check the BIOS memory information or run a tool such as dmidecode to confirm 2933 MT/s, CL21 timings and ECC registered status.
