64GB DDR4 ECC Registered RDIMM

This 64GB DDR4 2933MHz module is a 288-pin ECC Registered DIMM built for Supermicro X11 server and workstation boards. It operates at 1.2V with CL21 latency and a 2Rx4 rank configuration without a heat spreader. The module is validated for the X11DSN-TS, X11OPi-CPU, X11QPH+, X11QPL and X11SPA-T motherboards.

Suited for ECC registered server platforms only

This memory fits servers, workstations and NAS systems that require registered ECC DDR4. It will not work in standard desktop computers that use unbuffered non-ECC modules. It cannot be mixed with unbuffered memory. Buyers needing consumer desktop RAM or unbuffered ECC should look at a different product type.

Verify motherboard model and slot population rules

Confirm your board is one of the five listed Supermicro X11 models before ordering. Check the manual for maximum supported capacity per slot and the required population order for registered DIMMs. The module is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds. Ensure the system BIOS is current for full compatibility.

Questions about this item

Does my Supermicro X11DSN-TS motherboard need to support DDR4 ECC Registered RDIMM for this 64GB module to work?

Yes, the X11DSN-TS must accept DDR4 288-pin ECC Registered RDIMMs at 1.2V; this module is validated for that board and the listed X11 series models.

Can I add this 2933MHz CL21 RDIMM alongside existing 2666MHz ECC Registered modules in the same server?

The module is backward compatible with 2133MHz, 2400MHz and 2666MHz ECC Registered DIMMs; the system will run all populated slots at the lowest common speed.

How can I confirm the 64GB 2Rx4 RDIMM is detected at 2933MHz with ECC active after installation?

Check the BIOS memory information or run dmidecode — it should show 64GB, 2933MHz, CL21, 1.2V, ECC Registered, 2Rx4 organisation for the installed slot.
