Cisco UCS C220 M7 memory kit

This 192GB kit contains twelve 16GB DDR5 RDIMM modules built for the Cisco UCS C220 M7 rack server. Registered ECC design and 1.10V operation meet the platform's enterprise stability requirements. System administrators scaling memory capacity in validated Cisco hardware will use this part. It is not for buyers who need consumer DIMMs or non-ECC memory.

Registered ECC RDIMM format

Registered buffering and on-die ECC correct single-bit errors and reduce electrical load on the server memory controller. The 1Rx8 organisation keeps signal integrity high across all twelve slots at 4800 MT/s. No heat spreaders are included, matching the original Cisco thermal design. Builders who require unbuffered UDIMMs or modules with integrated heat spreaders cannot use this kit.

DDR5 4800 CL40 1.10V specification

Speed is DDR5 4800 (PC5-38400) with CAS latency CL40 at 1.10V across 288 pins. These three figures determine whether the modules train correctly in the Cisco UCS C220 M7 memory subsystem. Installers who need a different data rate, latency or voltage must select another part number.

Questions about this item

If one module fails in the 12x16GB kit, can I replace just that stick?

Yes, each 16GB DDR5 4800 CL40 1.10V ECC RDIMM is individually replaceable.

What limits sustained throughput on the Cisco UCS C220 M7 with this memory installed?

The DDR5 4800 PC5-38400 1Rx8 modules run at 1.10V with CL40 latency, setting the bandwidth and timing ceiling.

How much heat and power does the 192GB kit draw when the server runs all day?

Twelve registered DDR5 RDIMMs at 1.10V draw low power per module and have no heat spreaders, so airflow handles thermals.
