64GB DDR4 2933MHz ECC Registered RDIMM

This is a 64GB DDR4 2933MHz CL21 ECC Registered RDIMM from OWC. It operates at 1.2V on a 288-pin interface and uses a 2Rx4 rank configuration. The module is designed for server and workstation platforms that require registered memory with error correction.

Compatibility and constraints

It fits Supermicro motherboards X11DPFR-S, X11DPFR-SN, X11DPG-HGX2, X11DPG-OT-CPU and X11DPG-QT. The module runs at 2933MHz and is backward compatible with 2133MHz, 2400MHz and 2666MHz systems. It will not work in standard desktop computers and cannot be mixed with unbuffered memory.

Registered ECC requirement

The single specification that decides fit is the registered ECC design. Your system must support DDR4 registered DIMMs with ECC; unbuffered or non-ECC platforms will not accept this module.

Preguntas sobre este artículo

Does the 288-pin DDR4 RDIMM fit the DIMM slots on a Supermicro X11DPFR-S motherboard?

Yes, the 288-pin registered DIMM matches the DDR4 slots on the listed Supermicro X11DPF and X11DPG boards.

What is the correct way to seat the 64 GB module, and what step do builders often miss?

Align the module notch with the slot key, press down evenly until both side latches click, and verify the system reports the full 64 GB at 2933 MHz.

When should the ECC registered module be replaced in a server workload?

Replace the module if the platform ECC logger records recurring correctable errors or an uncorrectable error occurs.
