NEMIX RAM 384GB (12x32GB) DDR5 4800 CL40 ECC RDIMM Cisco UCS C220 M7 memory upgrade

System-Specific DDR5 Kit

This 384 GB kit contains twelve 32 GB DDR5 4800 CL40 registered ECC RDIMMs built for the Cisco UCS C220 M7 rack server. IT teams order it when the platform needs maximum supported capacity for virtualisation, databases or container workloads. The modules run at 1.1 V and use 1Rx4 organisation.

Sustained-Load Behaviour

Registered buffering and on-die ECC keep data integrity intact during continuous read-write cycles typical of hypervisor hosts. The 1.1 V operating voltage limits thermal output per module, helping the server’s airflow design maintain stable temperatures over long production shifts. CL40 latency is the standard JEDEC timing for this speed grade.

Upgrade Scope

The kit replaces any smaller-capacity DDR5 RDIMM population in the C220 M7, moving the system to its full 384 GB limit in a single step. The jump is worthwhile when current memory pressure forces paging or constrains VM density. Buyers who need a different form factor, non-ECC modules or a lower total capacity should look elsewhere.
