64 GB DDR4 RDIMM for Supermicro servers

This 64 GB registered DDR4 module targets administrators upgrading compatible Supermicro platforms. It delivers ECC protection and registered signalling for stable operation in multi-socket server and workstation workloads.

Capacity and headroom for virtualisation workloads

The single 64 GB stick adds substantial memory headroom for virtualisation hosts and database buffers. Systems limited to lower-density slots or lower maximum capacities will not accept this module.

DDR4 2666 interface limits bandwidth scaling

The PC4-21300 interface caps peak throughput at the rated 2666 MT/s. Workloads demanding higher memory bandwidth must move to a platform supporting faster DDR4 or DDR5 speeds.

Questions about this item

Will this 64 GB DDR4 2666 CL19 ECC RDIMM run alongside my existing 2666 MHz registered modules in a Supermicro server?

Yes, it matches the same DDR4 2666 speed, 1.2 V voltage, CL19 latency and registered ECC design, so it can operate with identical modules in supported Supermicro systems.

How can I verify the 2Rx4 registered ECC module is detected and running at 2666 MHz after installation?

Check the BIOS memory information screen or your operating system's hardware report; both should show 64 GB, DDR4 2666, ECC enabled and registered operation.

Does the single 64 GB 288-pin RDIMM ship with any cables, brackets or additional hardware?

No, the package contains only the 64 GB DDR4 2666 CL19 ECC RDIMM module itself; no cables, brackets or extra accessories are included.
