Cisco UCS C220 M7 DDR5 Kit

This 128 GB kit contains four 32 GB DDR5 4800 RDIMM modules built for the Cisco UCS C220 M7 rack server. The registered ECC design targets enterprise workloads that demand data integrity and maximum capacity per channel.

Verify DDR5 RDIMM slot count and voltage

Confirm the server has four available 288-pin DDR5 RDIMM slots and operates at 1.10 V before ordering. The modules run at CL40 latency and require a platform that supports registered ECC memory.

No heat spreader — airflow dependent cooling

Each module omits a heat spreader, so adequate chassis airflow is essential for sustained operation. The 1Rx4 organisation and major-brand Samsung, Micron or Hynix chips are validated for the Cisco memory subsystem.

Questions about this item

Does the kit include four 32GB modules or must they be purchased separately?

The kit contains four 32GB DDR5 RDIMM modules for a total of 128GB, so no additional modules are required.

Should I choose the 1Rx4 CL40 version or a different rank and latency?

This kit uses 1Rx4 organisation with CL40 latency at 4800 MT/s; other rank or latency options are not offered for this part number.

What does the 4800 MT/s rating deliver once installed in the Cisco UCS C220 M7?

The modules run at DDR5 4800 with 1.10V and ECC registered operation, matching the server's supported memory speed.
