SuperMicro DDR5 ECC RDIMM Kit

This 256 GB registered DDR5 kit contains four 64 GB modules built for SuperMicro CloudDC SuperServer platforms. ECC and registered signalling protect data integrity in mission-critical workloads. The kit targets IT teams that need validated, high-density memory for virtualization, database or HPC clusters.

4800 MT/s capacity and headroom

Running at 4800 MT/s (PC5-38400) with CL40 latency, the four modules deliver 256 GB of addressable memory per CPU socket. Dual-rank 2Rx4 organisation maximises density per channel. Workloads exceeding 256 GB per socket will require additional DIMM slots or higher-capacity modules.

1.10 V thermals and power draw

Operating at 1.10 V, the modules run without heat spreaders and rely on server chassis airflow for cooling. Registered buffering adds minimal latency while reducing electrical load on the memory controller. Power consumption scales linearly with active ranks under sustained load.

Questions about this item

Will this DDR5 4800 kit work alongside any DDR5 memory already installed in my Supermicro server?

This kit uses DDR5 4800 PC5-38400 2Rx4 1.10V CL40 registered ECC RDIMMs; mixing speeds, ranks, voltages or latencies can prevent the server from posting, so match every parameter exactly.

How can I confirm the 256GB kit is running at 4800 MT/s with ECC active after installation?

Enter the BIOS or use a tool like dmidecode to verify each 64GB module shows 4800 MT/s, CL40, 1.10V, registered ECC and 2Rx4 organisation.

What comes in the box and is anything else required for installation?

The box contains four 64GB DDR5 4800 CL40 288-pin ECC RDIMMs; no heat spreaders, cables or additional parts are included and nothing else is needed to install them.
