Cisco UCS C220 M7 memory kit

This 256GB kit contains eight 32GB DDR5 4800 CL40 registered ECC RDIMMs built for the Cisco UCS C220 M7 rack server. The modules run at 1.1V and use a 288-pin 1Rx4 layout with major OEM chips. It is intended for administrators expanding memory in that specific platform.

Who should consider this upgrade

IT teams running virtualisation, databases or container workloads on a Cisco UCS C220 M7 will gain the capacity and error correction those tasks demand. Buyers who need consumer DIMMs, non-ECC memory or a different form factor should look elsewhere.

Capacity and headroom

The eight-module population fills eight slots with 256GB total, operating at DDR5 4800 and CL40 latency. Registered buffering and ECC keep data integrity intact under sustained load. Workloads exceeding 256GB or requiring higher frequencies will outgrow this configuration.

Questions about this item

Does the Cisco UCS C220 M7 need any specific BIOS setting or firmware revision to recognise all eight 32 GB DDR5 4800 RDIMMs?

The kit is built for the Cisco UCS C220 M7 and uses standard DDR5 4800 registered ECC modules; the server’s own documentation will confirm any required BIOS or firmware level for full 256 GB population.

Can I keep existing DDR5 RDIMMs of a different speed or rank alongside these 1Rx4 CL40 modules in the same server?

Mixing ranks or speeds is not recommended; the server will run all channels at the lowest common speed and may require specific slot placement, so matching the 1Rx4 4800 specification across every populated slot gives the most reliable operation.

How do I confirm the full 256 GB kit is detected and running at 4800 MT/s with ECC active after installation?

Check the Cisco UCS BIOS or the operating-system memory report — it should show 256 GB total, DDR5 4800 speed, registered ECC status and the correct 1Rx4 organisation for each of the eight modules.
