Cisco UCS C220 M7 memory kit

This 2 TB kit contains sixteen 128 GB DDR5 RDIMMs built for the Cisco UCS C220 M7 rack server. Each module is a registered ECC DIMM operating at 1.1 V with a CAS latency of 40. The kit targets administrators who need maximum capacity in a single validated package.

DDR5 4800 registered ECC limits

The modules run at DDR5 4800 (PC5 38400) with a 4Rx4 organisation and 288-pin form factor. Registered buffering and on-die ECC add latency compared with unbuffered memory, so peak bandwidth is lower than consumer DDR5 at the same data rate. Systems that do not support registered ECC DDR5 cannot use these modules.

Major OEM chips without heat spreaders

Samsung, Micron or Hynix DRAM chips are used depending on supply, all tested under load for stability. The bare PCB design means airflow across the server chassis must handle cooling; no integrated spreader is present. Installers should verify that the server's memory population rules allow sixteen 4Rx4 modules before deployment.

Questions sur cet article

Should I choose the 16-module kit or buy smaller kits to reach 2TB?

The kit contains exactly 16 modules of 128GB each, so a single purchase delivers the full 2TB capacity for the Cisco UCS C220 M7 without mixing part numbers.

What does the 4800 MT/s rating mean once the memory is installed in the server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, delivering the rated throughput and timings when the Cisco UCS C220 M7 memory controller operates at its maximum supported DDR5 speed.

How does the 288-pin DDR5 RDIMM interface limit the usable speed in this server?

The 288-pin registered DDR5 form factor is keyed for the Cisco UCS C220 M7 slots, so the memory operates at the platform's native DDR5 4800 ceiling rather than any higher data rate.
