Server ECC RDIMM upgrade

This OWC module provides 64GB of DDR4 2933MHz ECC registered memory in a 288pin form factor. It runs at 1.2V with CL21 latency and a 2Rx4 rank configuration. The kit is validated for Supermicro motherboards X11DPT-L, X11DPT-PS, X11DPU, X11DPX-T and X11DSC+.

Suited for server and workstation builds

This memory targets administrators upgrading compatible Supermicro platforms or building new server and NAS systems that require ECC registered DIMMs. It is not for standard desktop computers and cannot be mixed with unbuffered modules. Buyers needing consumer desktop RAM should look elsewhere.

Verify motherboard compatibility first

Confirm your system is one of the listed Supermicro models before ordering. Check that the board supports DDR4 2933MHz registered ECC DIMMs and that you are not mixing with unbuffered memory. The module is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds.

Questions sur cet article

Do I need a Supermicro X11 series motherboard such as the X11DPT-L or X11DPX-T for this 64GB DDR4 2933MHz ECC RDIMM to work?

Yes, this module is validated for Supermicro X11DPT-L, X11DPT-PS, X11DPU, X11DPX-T and X11DSC+ motherboards that accept 288-pin DDR4 ECC registered DIMMs.

Can I add this CL21 1.2V registered ECC module alongside existing 2133MHz or 2400MHz DDR4 ECC RDIMMs in the same server?

The module is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 ECC registered DIMMs, but all slots must use registered ECC memory — unbuffered DIMMs cannot be mixed.

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

Check the BIOS memory information or OS tools such as dmidecode to verify 2933 MT/s speed, CL21 timings, 1.2 V operation and ECC enabled status.
