Capacity and role

This 64 GB DDR5 ECC registered DIMM is built for the ASUS RS720-E11-RS24U dual-socket server. It adds a single high-density module to expand memory capacity for virtualization, database or compute workloads.

Upgrade path

It replaces lower-capacity DDR5 RDIMMs or fills empty slots when the platform demands registered ECC memory at 4800 MT/s. The jump is worthwhile when workloads exceed the current memory ceiling and require error correction for data integrity.

Sustained behaviour

Operating at 1.1 V with CL40 latency, the module maintains stable throughput under continuous load thanks to on-die ECC and registered signalling. Rigorous stress testing under load confirms reliability for mission-critical environments.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the ASUS RS720-E11-RS24U server motherboard DIMM slots?

Yes, the module is a 288-pin DDR5 RDIMM built to the DDR5 4800 (PC5-38400) standard, which matches the memory slot specification of the ASUS RS720-E11-RS24U 2U dual-socket server.

What is the correct way to seat this registered ECC module, and which step is often missed?

Align the notch on the module with the key in the slot, press down evenly until both retention clips click, and ensure the server BIOS recognises the 64 GB capacity and ECC function — skipping the BIOS check is the step most installers forget.

When should I expect to replace this DDR5 ECC RDIMM in a production server?

The module uses Samsung, Micron or Hynix DRAM chips rated for continuous 1.10 V operation; under normal server workloads it typically remains reliable for the life of the platform, and NEMIX RAM backs it with a lifetime replacement warranty.
