256GB DDR5 ECC RDIMM kit for Cisco UCS C220 M7

This 256GB kit contains sixteen 16GB DDR5 4800 registered ECC modules built for the Cisco UCS C220 M7 rack server. Each module operates at 1.10V with CL40 latency and a 1Rx8 organisation. The 288-pin RDIMM form factor matches the server's memory slots exactly.

Sustained load behaviour with registered ECC DDR5

Registered buffering and on-die ECC correct single-bit errors in real time while the register reduces electrical load on the memory controller during continuous operation. The 1.10V operating voltage and major OEM DRAM from Samsung, Micron or Hynix maintain stable signalling across all sixteen modules under prolonged enterprise workloads.

Cisco UCS C220 M7 compatibility decides fit

The kit is validated for the Cisco UCS C220 M7 and will not function in systems that require unbuffered UDIMMs, different pin counts, other DDR generations or non-ECC memory. Buyers needing consumer desktop RAM, laptop SO-DIMMs or higher-speed server modules must select a different product.

Questions about this item

How much power does the 1.1V DDR5 4800 kit draw when the Cisco UCS C220 M7 runs continuously?

Each 16 GB module operates at 1.10 V; total consumption depends on the server's workload and memory-controller configuration, not on the modules alone.

What must the Cisco UCS C220 M7 already support for these 288-pin RDIMMs to function?

The server must accept DDR5 4800 registered ECC RDIMMs in a 1Rx8 organisation and provide 16 DIMM slots for the full 256 GB kit.

Will the CL40 registered modules work alongside any existing DDR5 memory already installed in the Cisco UCS C220 M7?

Mixing is possible only if the existing modules are also DDR5 4800 registered ECC RDIMMs with identical rank and voltage; otherwise the system will default to the slowest common timing.
