Cisco UCS C240 M7 memory kit

This 512GB kit contains eight 64GB DDR5 4800 registered ECC RDIMM modules built for the Cisco UCS C240 M7 rack server. Each module runs at 1.1V with CL40 latency and a 2Rx4 organisation. The kit is new and uses major-brand Samsung, Micron or Hynix chips.

Who should use this kit

IT teams expanding a Cisco UCS C240 M7 to its maximum supported capacity will match the qualified part number MR38400-924K8 exactly. Buyers who need unbuffered memory, non-ECC modules, a different speed grade or a smaller total capacity should look at other options.

288-pin DDR5 RDIMM form factor

The modules use the standard 288-pin DDR5 RDIMM connector with registered buffering and on-die ECC. This physical and electrical interface determines whether the memory fits and functions in the target server.

Questions about this item

How much heat does the 1.10V DDR5 4800 kit produce when all eight modules run continuously?

Each 64GB module operates at 1.10V with no heat spreader, so sustained load relies on chassis airflow to dissipate heat from the registered DDR5 components.

What server slots and firmware are required to install this 8x64GB registered kit?

The kit needs eight free 288-pin DDR5 RDIMM slots in a Cisco UCS C240 M7 and BIOS support for 2Rx4 ECC registered modules at PC5-38400 speed.

Will the CL40 2Rx4 modules work alongside any existing 1Rx8 or 2Rx8 DDR5 RDIMMs already in the server?

Mixing 2Rx4 modules with different rank architectures is not recommended; populate all eight slots with this matched kit for stable operation.
