NEMIX RAM 256GB (2x128GB) DDR5 4800 CL40 288-Pin ECC RDIMM Cisco UCS X410c M7 memory upgrade

Cisco UCS X410c M7 memory kit

This 256GB kit supplies two 128GB DDR5 RDIMMs built for the Cisco UCS X410c M7 compute node. ECC and registered operation protect data integrity in virtualised and database workloads. The modules run at 4800 MT/s with CL40 latency at 1.10V. They target administrators who need validated capacity for a single supported platform.

Sustained load behaviour

Registered buffering and on-die ECC keep error rates low during continuous memory-intensive tasks such as in-memory analytics or container hosting. The 4Rx4 organisation spreads traffic across four ranks per module, helping the memory controller maintain throughput over long runs. No heat spreader is fitted, so airflow across the DIMM slots must meet the chassis specification to avoid thermal throttling.

Installation notes

The 288-pin DDR5 form factor keys into the X410c M7 slots in one orientation; forcing a module can damage the socket. Mixing these 128GB 4Rx4 RDIMMs with different capacities, ranks or voltages in the same channel will prevent the system from posting. Always follow the Cisco memory population guide for the exact slot order and firmware version required.
