Cisco UCS X210c M7 memory upgrade

This 1 TB kit contains eight 128 GB DDR5 4800 registered ECC RDIMMs built for the Cisco UCS X210c M7 compute node. Each module runs at 1.1 V with CL40 latency and a 4Rx4 organisation. The memory is designed for enterprise servers that require registered error-correcting modules.

Registered DDR5 4800 for Cisco blade slots

The kit plugs directly into the 288-pin DDR5 RDIMM slots of the X210c M7 without adapters. Registered buffering reduces electrical load on the memory controller, allowing all eight modules to operate together. ECC protects data integrity under sustained workloads. No heat spreaders are fitted, so airflow in the chassis handles cooling.

Eight matched modules simplify deployment

The package delivers a single part number (MR38400-744K8) covering the full 1 TB capacity, removing the need to source individual sticks. Matched kits reduce the risk of timing mismatches during POST. Modules use major OEM Samsung, Micron or Hynix components and are stress tested before shipment.

Questions about this item

Does the CL40 latency limit throughput when the memory runs at DDR5 4800 under sustained load?

CL40 is the rated CAS latency at 4800 MT/s; it defines the timing budget the controller follows during continuous operation.

How much heat or power does an eight-module 1.1 V kit produce when running all day in a Cisco UCS X210c M7?

Each 128 GB module operates at 1.1 V; the registered design and ECC logic add minimal overhead, so total heat scales with the eight-module population.

Must the Cisco UCS X210c M7 compute node already support 4Rx4 registered DDR5 RDIMMs for this kit to work?

Yes — the kit is 288-pin DDR5 RDIMM, 4Rx4, ECC registered, and validated for the X210c M7 platform.
