Cisco UCS C220 M7 memory kit

This 512GB kit supplies four 128GB DDR5 RDIMMs built for the Cisco UCS C220 M7 rack server. Registered ECC operation and a CL40 latency profile target enterprise workloads that require data integrity and high capacity per slot.

Fills all four channels with registered modules

Each stick uses a 4Rx4 organisation and 288-pin DDR5 form factor so the server memory controller can address the full 512GB without additional buffering hardware. The 1.1V operating voltage matches the platform specification and leaves headroom for dense configurations.

Runs at 4800 MT/s with standard DDR5 power draw

Modules operate at the rated JEDEC speed without overclocking, keeping thermals predictable in a passively cooled server chassis. No heat spreaders are fitted, so airflow from the system fans provides the only cooling path.

Questions sur cet article

Does the CL40 latency become a bottleneck when the kit runs at 4800 MT/s under sustained heavy load?

At 4800 MT/s the CL40 timing is the native specification for this DDR5 registered kit; latency scales with the rated speed and the server memory controller manages it automatically.

How much heat does the 1.1 V registered 4Rx4 design generate during all-day operation?

The modules run at the standard DDR5 server voltage of 1.1 V with no heat spreader, relying on chassis airflow; registered 4Rx4 organisation is typical for dense 128 GB DIMMs in rack servers.

Which Cisco server must I already own for this 288-pin ECC RDIMM kit to be compatible?

The kit is validated for the Cisco UCS C220 M7 rack server; it plugs directly into that platform’s DDR5 RDIMM slots without additional hardware.
