Cisco UCS C240 M7 compatible DDR5 RDIMM

This 16 GB registered DDR5 module is validated for the Cisco UCS C240 M7 rack server. It delivers 4800 MT/s bandwidth with CL40 latency and on-die ECC for data integrity in enterprise workloads. The single-rank 1Rx8 organisation keeps electrical loading low on populated memory channels.

Fits Cisco server memory slots without adapter

The 288-pin RDIMM form factor installs directly into the C240 M7 DIMM sockets and operates at the standard 1.1 V DDR5 voltage. Registered buffering reduces signal load on the memory controller, freeing electrical headroom for additional modules on the same channel. No heat spreader is fitted, so airflow clearance follows the server chassis design.

Sustained throughput with ECC protection

Under continuous load the module maintains rated 4800 MT/s speed while ECC corrects single-bit errors in real time. Registered signalling stabilises command timing across multiple ranks, preventing timing drift during long compute runs. The 1.1 V supply keeps power draw predictable for dense server configurations.

Questions about this item

Will the 1.1V DDR5 4800 module hit thermal throttling during sustained server workloads?

The module operates at 1.10V without a heat spreader; sustained loads rely on chassis airflow to keep temperatures within DDR5 limits.

How much noise or heat does this registered ECC RDIMM add when the Cisco UCS C240 M7 runs continuously?

The RDIMM itself is silent and draws 1.10V; any audible noise or extra heat comes from the server fans managing total system thermals.

What must the Cisco UCS C240 M7 already have for this 288-pin DDR5 4800 RDIMM to function?

The server needs an available DDR5 RDIMM slot and a BIOS that supports 16GB 1Rx8 ECC registered modules at 4800 MT/s.
