Cisco UCS X210c M7 memory kit

This 1.5 TB kit contains twelve 128 GB DDR5 modules built for the Cisco UCS X210c M7 compute node. It delivers registered ECC memory for enterprise workloads that require data integrity and high capacity.

Registered ECC and 4Rx4 organisation

The modules operate at 4800 MT/s with CL40 latency and 1.1 V voltage. Registered buffering and 4Rx4 rank structure reduce electrical load on the memory controller, allowing all twelve DIMMs to run together without signal degradation.

288-pin RDIMM form factor

Each stick uses the standard 288-pin DDR5 RDIMM layout and has no heat spreader, so it fits the Cisco node’s memory slots directly. The kit is validated for that specific platform, eliminating guesswork during installation.

Questions about this item

Will the 12 modules in this 1.5TB kit need any replacement or maintenance over time?

DDR5 RDIMM modules are solid-state components with no moving parts; they do not require scheduled maintenance or periodic replacement under normal server operating conditions.

What is the first limit reached when the 4Rx4 registered DIMMs run sustained workloads on the Cisco UCS X210c M7?

The 4Rx4 organisation places a higher electrical load on the memory controller, so the platform's maximum supported rank-per-channel limit is typically reached before bandwidth or capacity ceilings.

How much heat and power do the twelve 1.1V DDR5 4800 RDIMMs produce when the compute node runs all day?

Each module operates at 1.1V DDR5 standard voltage; total kit power scales with the 12-module population, and registered DIMMs add minimal overhead compared with unbuffered equivalents.
