Cisco UCS C220 M7 256GB DDR5 Kit

This 256GB kit contains two 128GB DDR5 4800 ECC registered DIMMs built for the Cisco UCS C220 M7 rack server. Each module runs at 1.1V with CL40 latency and a 4Rx4 organisation. The registered design adds a buffer that stabilises heavy memory loads in enterprise environments.

Upgrading from smaller RDIMM sets

Replacing lower-capacity registered DIMMs with this 2×128GB kit doubles or quadruples the memory pool available to virtualisation hosts and database engines. The jump is worth it when workloads exceed the current installed capacity and the server’s memory slots support 128GB per slot at 4800 MT/s.

Tool-less DIMM installation

The 288-pin DDR5 modules seat vertically in the server’s memory channels and lock with the ejector levers; no screws or cables are required. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong channel order, or failing to update the system firmware before the first boot.

Questions sur cet article

Does the 288-pin DDR5 RDIMM form factor fit the Cisco UCS C220 M7 memory slots?

Yes, the 288-pin DDR5 RDIMM modules match the Cisco UCS C220 M7 DIMM slots exactly.

What BIOS setting or installation step is often missed when adding these 4Rx4 registered ECC modules?

The server BIOS must be updated to the latest revision before installing the 4Rx4 registered ECC DIMMs so the memory controller recognises the rank configuration.

When will the Samsung, Micron or Hynix DRAM chips on these 128 GB modules need replacement under normal server load?

The DRAM chips are rated for continuous enterprise operation and do not have a scheduled replacement interval; they are covered by a lifetime replacement warranty.
