Cisco UCS X210c M7 compatible DDR5 RDIMM

This NEMIX RAM module delivers 128GB of DDR5 4800 ECC registered memory in a single 288-pin DIMM. It is built for the Cisco UCS X210c M7 compute node and uses Samsung, Micron or Hynix components. The CL40 timing and 1.10V operation match the platform specification.

Upgrade path for Cisco UCS X210c M7 servers

The module replaces lower-capacity DDR5 RDIMMs in the X210c M7 when additional memory channels are populated or when a single-slot 128GB density is required. The jump is worth it when workloads exceed the capacity of smaller registered DIMMs and the system board supports 4Rx4 organisation.

128GB density for virtualisation

The 4Rx4 organisation provides high capacity per slot, letting the X210c M7 reach large memory footprints for virtualisation hosts or in-memory databases. Headroom ends when the compute node reaches its maximum DIMM count or when applications demand bandwidth beyond DDR5 4800.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Cisco UCS X210c M7 compute node?

Yes, the 288-pin DDR5 RDIMM is built to the mechanical and electrical specification for the Cisco UCS X210c M7 compute node.

What is the correct slot population order when installing this 4Rx4 module?

Follow the Cisco UCS X210c M7 service guide; populate the designated CPU channels in the sequence shown to avoid a rank-interleaving mismatch.

When should the 128GB DDR5 ECC RDIMM be replaced?

Replace the module if ECC correctable-error counters rise steadily or if the system logs uncorrectable memory errors during POST.
