Cisco UCS C240 M7 compatible kit

This 1 TB kit contains eight 128 GB DDR5 RDIMM modules built for the Cisco UCS C240 M7 rack server. Each module runs at 4800 MT/s with CL40 latency at 1.1 V and uses a 4Rx4 organisation with on-die ECC. The registered design adds a buffer that helps the memory controller manage heavy loads in multi-socket configurations.

Suited for Cisco UCS C240 M7 upgrades

Administrators expanding memory in a Cisco UCS C240 M7 will find the kit validated for that platform. Systems that require unbuffered DIMMs, a different pin count, or a lower density per module cannot use this memory. Buyers needing non-ECC consumer memory or a different server model should look elsewhere.

Eight matched modules in one package

The kit ships as a matched set of eight 128 GB sticks, removing the need to source individual modules and reducing the risk of mixing revision codes. No heat spreaders are included, so airflow in dense chassis must be managed by the server’s own cooling. No additional software or firmware is bundled.

Questions about this item

Does the Cisco UCS C240 M7 server need to support DDR5 4800 RDIMMs and have eight free 288-pin slots to use this 1 TB kit?

Yes, the kit contains eight 128 GB DDR5 4800 CL40 1.1 V 4Rx4 ECC registered DIMMs on 288-pin RDIMM form factor, so the host must accept DDR5 RDIMMs at that speed and provide eight available memory slots.

Can these 4Rx4 modules be mixed with lower-rank DDR5 RDIMMs already installed in the Cisco UCS C240 M7?

Mixing different rank configurations is not recommended; the server memory controller expects consistent rank-per-channel topology, so populate all channels with matching 4Rx4 modules for stable operation.

After installation, how can I verify the kit is running at DDR5 4800 CL40 with ECC active?

Check the BIOS memory information or Cisco UCS Manager inventory; it should show 1 TB total capacity, 4800 MT/s data rate, CL40 latency, 1.10 V voltage and ECC enabled on every module.
