Capacity and purpose

This kit provides 256GB of DDR5 memory arranged as eight 32GB registered DIMMs for the Cisco UCS X410c M7 compute node. It targets IT teams expanding capacity in mission-critical server deployments where error correction and registered buffering are required. Buyers needing unbuffered or non-ECC modules for desktop platforms cannot use this kit.

Build and connectors

Each module is a 288-pin RDIMM operating at 1.1V with a CL40 latency and 1Rx4 organisation. The registered design adds a buffer that reduces electrical load on the server memory controller, supporting stable operation in high-density configurations. No heat spreaders are fitted, so airflow through the chassis must be sufficient for bare modules.

Thermals and power

Running at the standard DDR5 4800 speed and 1.10V, the modules draw minimal power per DIMM while delivering PC5-38400 bandwidth. Registered buffering and ECC logic add negligible thermal load compared with unbuffered equivalents. In a properly ventilated Cisco UCS X410c M7 chassis the kit operates within normal server temperature and acoustic envelopes.

Questions about this item

What does the DDR5 4800 PC5-38400 rating mean for the 288-pin RDIMM interface on the Cisco UCS X410c M7?

The kit runs at 4800 MT/s with CL40 latency, delivering the standard PC5-38400 data rate across the 288-pin registered DDR5 interface.

What physical clearance does the 8-module kit need inside the Cisco UCS X410c M7 compute node?

Eight 32 GB 1Rx4 RDIMMs occupy eight 288-pin DDR5 slots; the modules have no heat spreaders, so standard server DIMM clearance applies.

How are the registered ECC modules installed in the Cisco UCS X410c M7, and what step is often missed?

Align each 288-pin RDIMM with the keyed slot, press firmly until both ejector tabs click, and verify the BIOS recognises all 256 GB at 4800 MT/s.
