Cisco UCS X210c M7 memory kit

This 256 GB kit contains four 64 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 2Rx4 organisation. The registered design adds a buffer that helps signal integrity in dense server configurations.

Upgrading from lower-capacity DDR5 RDIMMs

Replacing smaller registered modules with this 4 × 64 GB kit raises total capacity to 256 GB in a single step. The jump is worthwhile when workloads such as virtualisation, in-memory databases or large-container fleets need more addressable memory than the current population provides.

Suited for Cisco UCS X210c M7 nodes

Administrators expanding memory in a Cisco UCS X210c M7 will find the correct form factor, voltage and registration here. Builders using consumer motherboards, non-Cisco servers or platforms that require unbuffered DIMMs or a different pin count should look at other memory.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on the Cisco UCS X210c M7?

Yes, the 288-pin DDR5 RDIMM form factor matches the Cisco UCS X210c M7 memory slots for direct installation.

What is the correct order to install the four 64GB modules for proper registered ECC operation?

Follow the Cisco UCS X210c M7 manual to populate the designated DDR5 channels in the prescribed sequence for 2Rx4 registered modules.

When should the 256GB DDR5 4800 kit be replaced if ECC correctable errors increase over time?

Replace the kit if the system logs show a rising trend of correctable ECC errors or if memory diagnostics report persistent failures.
