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.

Questions about this item

How much power does the 1.1 V DDR5 4800 kit draw when the Cisco UCS X410c M7 runs continuously?

Each 128 GB module operates at 1.10 V; total draw depends on server workload and the X410c M7 power management settings.

What must the Cisco UCS X410c M7 already have for this 256 GB RDIMM kit to function?

The compute node must support DDR5 4800 ECC registered 288-pin RDIMMs with 4Rx4 organisation and have two free DIMM slots.

Will the CL40 4Rx4 modules work alongside any existing DDR5 RDIMMs already installed in the X410c M7?

Mixing ranks or latencies can prevent the node from booting; populate all slots with identical 4Rx4 CL40 modules for guaranteed operation.
