Cisco UCS C220 M7 memory kit

This 512GB kit contains eight 64GB DDR5 registered DIMMs validated for the Cisco UCS C220 M7 rack server. Each module operates at 4800MHz with CL40 latency and 1.1V power draw. The ECC registered design protects data integrity in mission-critical workloads.

Enterprise server administrators only

IT teams managing Cisco UCS C220 M7 deployments gain a matched 8-module set that simplifies capacity expansion. Buyers who need non-ECC memory, unbuffered DIMMs, or speeds beyond 4800MHz should look at other product lines. Systems outside the Cisco UCS C220 M7 platform are not supported by this specific kit.

DDR5 4800 registered ECC 288-pin

The single specification that decides fitment is the DDR5 4800 registered ECC 288-pin RDIMM form factor. Only servers accepting this exact module type can use the kit. The 2Rx4 organisation and 1.10V voltage are fixed by the module design. Confirm the server memory list before ordering.

Questions about this item

Does the Cisco UCS C220 M7 server need to support DDR5 4800 registered ECC memory for this 8-module kit to function?

Yes, the kit is DDR5 4800 PC5-38400 CL40 2Rx4 1.1V registered ECC RDIMM; the server must accept DDR5 registered ECC modules at that speed and voltage.

Can I keep any existing DDR5 4800 registered ECC modules already installed in the Cisco UCS C220 M7 alongside this 512GB kit?

Yes, provided the installed modules are also DDR5 4800 registered ECC RDIMMs with matching voltage and rank configuration, the server can populate remaining slots with this kit.

After installation, how do I confirm the Cisco UCS C220 M7 recognises all 512GB at DDR5 4800 with ECC active?

Check the server BIOS or Cisco IMC inventory; it should show 512GB total, DDR5 4800 speed, registered ECC mode enabled, and all eight 64GB modules listed without errors.
