Cisco UCS X210c M7 Memory Kit

This 768 GB kit contains six 128 GB DDR5 4800 ECC registered DIMMs built for the Cisco UCS X210c M7 compute node. It targets IT teams running memory-intensive workloads on that specific platform.

Upgrade from smaller or slower DDR5 kits

The jump is worth it when your Cisco node needs the full 768 GB capacity at 4800 MT/s with CL40 latency and 1.1 V operation. It replaces partial population or lower-density modules that limit virtualization density.

Install by seating each 288-pin RDIMM

Follow the Cisco node manual for population order and BIOS settings. The most common issue is mismatched rank configuration or skipping the required firmware update before boot.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Cisco UCS X210c M7 compute node?

Yes, the kit is built for the Cisco UCS X210c M7 and uses the 288-pin DDR5 RDIMM form factor that the node's memory slots accept.

What is the correct order to populate the six 128 GB modules in the Cisco UCS X210c M7?

Follow the Cisco UCS X210c M7 manual's slot population sequence; the 4Rx4 registered modules must be installed in the prescribed channels for the node to recognise all 768 GB.

When should the 1.1 V DDR5 4800 RDIMMs be replaced in a production Cisco UCS X210c M7?

Replace modules only if ECC correctable errors rise above the platform threshold or if the node fails memory diagnostics during scheduled maintenance.
