Cisco UCS C220 M7 compatible DDR5 ECC RDIMM

This 64GB NEMIX RAM module is a registered DDR5 DIMM with ECC built for the Cisco UCS C220 M7 rack server. It targets IT teams that need validated memory for mission-critical enterprise workloads. The single-module kit delivers 64GB of capacity at the standard DDR5-4800 data rate.

Verify DDR5 RDIMM slot availability

Confirm the server has a free 288-pin DDR5 RDIMM slot and check the Cisco memory population guide for the C220 M7 before ordering. The module operates at 1.1V with CL40 latency and uses a 2Rx4 organisation. Mixing ranks or voltages can prevent the system from posting.

Sustained enterprise workloads

Registered buffering and on-die ECC keep data integrity intact during continuous database, virtualisation or analytics tasks. The module is stress-tested under load to maintain stability without throttling. Absence of a heat spreader means airflow across the DIMM slots must meet Cisco thermal specifications.

Questions about this item

What comes in the box and is anything else required to install the 64GB DDR5 4800 CL40 2Rx4 ECC RDIMM?

The box contains one 64GB 288-pin DDR5 RDIMM module. No extra parts are needed; it installs directly into a compatible Cisco UCS C220 M7 server slot.

Should I choose the 64GB 2Rx4 CL40 version or a different capacity for my Cisco UCS C220 M7?

This 64GB 2Rx4 CL40 module matches the Cisco UCS C220 M7 qualified configuration. Select it when you need a single 64GB registered ECC DIMM at 4800 MT/s.

What does the 4800 MT/s rating mean once the module is running in the server?

The module operates at 4800 MT/s (PC5-38400) with CL40 latency at 1.10 V, delivering the rated bandwidth and error-corrected throughput the Cisco platform expects.
