Server Memory Kit for Cisco UCS C240 M7

This NEMIX RAM kit provides 64GB of DDR5 ECC registered memory in two 32GB modules. It runs at 4800MHz with CL40 latency and 1.10V operation. The 288-pin RDIMMs use 1Rx4 organisation with major OEM chips. The kit is validated for the Cisco UCS C240 M7 rack server.

Suited for ECC Registered Slots Only

The modules require a platform that supports DDR5 ECC RDIMM memory with registered buffering. Systems needing unbuffered UDIMMs, non-ECC memory or a different DDR generation cannot use this kit. Builders without registered memory slots should look elsewhere.

64GB DDR5 4800 ECC RDIMM Capacity

The single specification that decides fit is the 64GB (2x32GB) DDR5 4800 ECC registered RDIMM configuration. Your server must accept this exact capacity, speed, form factor and error-correction type for the upgrade to work.

Questions about this item

How do I verify the kit is running at DDR5 4800 with CL40 after installation?

Check the BIOS or a tool such as CPU-Z to confirm the memory reports 4800 MT/s, CAS latency 40 and 1.10 V on each 32 GB module.

What ships in the box and is anything else required for the Cisco UCS C240 M7?

The package contains two 32 GB 288-pin DDR5 RDIMMs for a total of 64 GB; no extra parts are needed for the supported server.

Which capacity version should I choose for a Cisco UCS C240 M7 that needs 64 GB in a two-module kit?

Select the 64 GB kit (2 x 32 GB) with part number MR38400-314K2 to match the server's validated configuration.
