Cisco UCS C240 M7 DDR5 kit

This 192GB kit contains six 32GB DDR5 4800 CL40 registered ECC RDIMMs built for the Cisco UCS C240 M7 rack server. Each module runs at 1.1V and uses a 1Rx4 organisation with major OEM chips. The registered design adds a buffer for signal integrity in multi-DIMM server configurations.

Pre-install checklist

Verify the server is a Cisco UCS C240 M7 and count the free 288-pin DDR5 slots to ensure all six modules can be seated. Check the current BIOS version against Cisco guidance for 4800MT/s registered memory support. Confirm the existing population rules allow 1Rx4 RDIMMs in the target channels.

Thermals noise and power

Modules operate at the standard DDR5 1.1V with no heat spreader fitted, relying on chassis airflow for cooling. Registered buffering adds negligible power draw per DIMM under normal load. No active cooling components are present so acoustic contribution is limited to the server's own fans.

Questions about this item

What does the 192 GB kit contain and is anything else required?

The kit contains six 32 GB DDR5 4800 CL40 1.1 V ECC RDIMM modules; no additional parts are needed for installation in a compatible Cisco UCS C240 M7 server.

Why choose this 192 GB kit instead of a smaller capacity?

The six-module 192 GB configuration fills the available slots with 1Rx4 registered ECC memory, maximising capacity while keeping the DDR5 4800 speed and 1.1 V operation specified for the Cisco UCS C240 M7.

What does the DDR5 4800 rating mean for real-world server performance?

DDR5 4800 (PC5-38400) delivers 4800 MT/s data rates with CL40 latency at 1.1 V, providing the bandwidth and error correction the Cisco UCS C240 M7 expects for stable operation under load.
