Capacity and compatibility

This kit provides 1.5TB of DDR5 memory across twelve 128GB registered DIMMs. It is validated for the Cisco UCS C240 M7 rack server and uses ECC RDIMM modules that meet the platform's registered memory requirement.

Sustained workload behaviour

Each module runs at DDR5 4800 with CL40 latency and 4Rx4 organisation. The registered buffer and ECC circuitry maintain data integrity during continuous enterprise workloads without relying on consumer-grade timing profiles.

Thermals and power

Modules operate at 1.1V and ship without heat spreaders, relying on the server's directed airflow for cooling. The low voltage and registered design help constrain power draw per DIMM under typical server utilisation.

Questions about this item

How much power does the 1.1V DDR5 4800 kit draw when the Cisco UCS C240 M7 runs continuously?

Each 128GB module operates at 1.1V; total system power depends on the server's memory controller and workload, not on the modules alone.

What must the Cisco UCS C240 M7 already support to accept this 12-module 1.5TB registered ECC kit?

The server needs 12 free 288-pin DDR5 RDIMM slots, a memory controller that handles 4Rx4 registered ECC at 4800 MT/s, and BIOS/firmware qualified for 128GB per DIMM.

Can the 12x128GB CL40 4Rx4 DDR5 modules share memory channels with smaller DDR5 RDIMMs already installed in the Cisco UCS C240 M7?

Mixed capacities and ranks are allowed only if the platform's memory reference code supports the specific population rules; consult the Cisco UCS C240 M7 memory installation guide for approved configurations.
