  • DDR5 4800 speed handles demanding workloads
  • ECC registered design protects data integrity
  • 10 V operation reduces power draw
  • Validated for Cisco UCS C240 M7

Cisco UCS C240 M7 memory kit

This 64 GB kit contains four 16 GB DDR5 RDIMM modules built for the Cisco UCS C240 M7 rack server. Registered ECC operation protects data integrity in mission-critical workloads. The kit arrives as a matched set to simplify installation in qualified Cisco platforms.

64 GB capacity with CL40 latency

Four single-rank 1Rx8 modules deliver 64 GB total at 4800 MT/s with CAS latency 40. The 1.1 V operating voltage keeps power draw low for dense server configurations. Workloads exceeding this capacity will require additional DIMM slots or higher-density modules.

DDR5 RDIMM registered interface

The 288-pin DDR5 RDIMM form factor uses registered signalling and on-die ECC for signal integrity at 4800 MT/s. Systems not designed for DDR5 registered ECC memory cannot accept these modules. Compatibility is limited to platforms that explicitly support this DDR5 RDIMM specification.

Questions about this item

Will the 4800 CL40 modules run without errors when installed alongside existing DDR5 RDIMMs in the Cisco UCS C240 M7?

The kit is validated for the Cisco UCS C240 M7 and uses standard DDR5 4800 CL40 1.1 V registered ECC timings; matching speed, voltage, rank and ECC type with any other DDR5 RDIMMs already in the server lets the memory controller train all channels together.

How can I confirm the 64 GB kit is operating at 4800 MT/s with ECC active after installation?

Check the BIOS memory information or Cisco IMC inventory — both report each DIMM at 4800 MT/s, CL40, 1Rx8, registered ECC, and show the total capacity as 64 GB.

Does the package include only the four 16 GB RDIMMs or are any tools or cables also supplied?

The box contains only the four 16 GB DDR5 4800 CL40 288-pin ECC RDIMMs; no tools, cables or additional hardware are included.
