Cisco UCS C240 M7 memory kit

This 384GB kit contains six 64GB DDR5 ECC RDIMM modules built for the Cisco UCS C240 M7 rack server. Registered buffering and on-die ECC protect data integrity in multi-socket workloads. The kit arrives as a matched set so the platform can populate all channels at once.

2Rx4 organisation and 1.10V operation

Each module uses a 2Rx4 layout that lets the memory controller address two ranks per DIMM without extra electrical load. Running at the standard 1.10V keeps power draw predictable inside dense chassis. No heat spreaders are fitted, so airflow must follow the server vendor’s ducting design.

DDR5 4800 CL40 registered DIMM

The decisive spec is the DDR5 4800 speed with CL40 latency in a 288-pin registered form factor. Only systems qualified for PC5-38400 registered ECC memory will accept this kit; consumer boards and unbuffered platforms cannot use it.

Questions about this item

Will the 2Rx4 ECC registered DIMMs need any firmware updates or periodic reseating after installation?

The modules are rigorously stress tested before shipment and carry a lifetime replacement guarantee; no firmware updates or scheduled reseating are required for the 2Rx4 ECC RDIMMs.

What thermal limit appears first when all six 64 GB modules run continuously at 4800 MT/s?

Operating at 1.10 V without heat spreaders, the DIMMs rely on chassis airflow; sustained loads will hit the DDR5 thermal throttle point before any voltage or power ceiling is reached.

How much power does the full 384 GB kit draw and how loud are the modules under 24/7 server load?

At 1.10 V each 64 GB RDIMM draws minimal power and the modules themselves are silent; total kit consumption stays low and any noise comes only from system fans moving air across the 288-pin DIMMs.
