NEMIX RAM 512GB (16x32GB) DDR5 4800 CL40 ECC RDIMM Cisco UCS C240 M7 memory upgrade

Cisco UCS C240 M7 memory kit

This 512 GB kit contains sixteen 32 GB DDR5 4800 registered ECC RDIMMs built for the Cisco UCS C240 M7 rack server. It targets IT teams who need maximum supported capacity for virtualisation, database or analytics workloads on that specific platform. The modules run at 1.1 V with CL40 latency and a 1Rx4 organisation. Buyers who need non-ECC memory or a different form factor cannot use this kit.

Sustained-load behaviour

Each module is stress tested under load before shipment to verify stability during continuous operation. Registered buffering and ECC correction maintain data integrity when all sixteen slots are populated and the server runs at full capacity for extended periods. The 1.1 V operating voltage helps keep power draw predictable across the full configuration. No thermal throttling data or error-rate figures are supplied.

Installation notes

The 288-pin DDR5 RDIMMs insert vertically into the server's memory slots; no heat spreaders are present, so clearance inside the chassis is not increased. Cisco's own service guide should be followed for the correct population order across all sixteen slots. Mixing these modules with different speeds, ranks or vendors may prevent the system from posting or cause intermittent errors.
