Cisco UCS C240 M7 memory kit

This 512GB kit contains four 128GB DDR5 4800 RDIMM modules built for the Cisco UCS C240 M7 rack server. It delivers ECC registered memory with a CL40 latency and 1.1V operation for enterprise workloads.

Simple DIMM installation

Installation follows standard server DIMM procedures and typically takes minutes per the manufacturer. Ensure the server is powered down and anti-static precautions are observed; the most common issue is failing to seat all four modules fully in the correct slots.

Verify Cisco UCS C240 M7 compatibility

Confirm the target system is a Cisco UCS C240 M7 before ordering. This kit is validated for that specific platform; other servers or motherboards may not support 4Rx4 registered DDR5 at 4800MT/s.

Questions about this item

How can I verify the 512GB kit is running at 4800 MT/s with CL40 after installation?

Enter the server BIOS or use a tool like CPU-Z to confirm the memory operates at 4800 MT/s and shows CAS latency 40 across all four modules.

What does the kit contain and is anything else required for the Cisco UCS C240 M7?

The package includes four 128GB 288-pin DDR5 RDIMMs; no extra parts are needed for a standard memory upgrade.

Why choose the 4Rx4 512GB kit over a lower-capacity option for this server?

The 4Rx4 organisation delivers maximum density per slot, letting you reach 512GB using only four DIMM sockets on the C240 M7.
