NEMIX RAM 128GB DDR5 4800 CL40 4Rx4 ECC RDIMM Cisco UCS C220 M7

128GB DDR5 4800 ECC RDIMM for Cisco UCS C220 M7

This 128GB DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It is built as a 4Rx4 registered DIMM with on-die ECC for data integrity. The part is validated for the Cisco UCS C220 M7 rack server and uses major OEM chips from Samsung, Micron or Hynix.

288-pin registered form factor with no heat spreader

The module uses the standard 288-pin DDR5 RDIMM connector and registered buffering to reduce electrical load on the memory controller. No heat spreader is fitted, so airflow in the server chassis provides cooling. The single-stick 128GB density lets administrators populate fewer slots while reaching high total capacity.

Replaces lower-capacity DDR5 RDIMMs in the same

Upgrading from smaller registered modules increases the memory ceiling for virtualisation, databases and analytics workloads. The jump is worthwhile when the Cisco UCS C220 M7 needs more capacity per channel and the workload benefits from the 4Rx4 organisation. Buyers who need non-ECC or unbuffered memory should look elsewhere.
