NEMIX RAM 16GB DDR5 4800 CL40 1Rx8 ECC RDIMM Cisco UCS X210c M7 memory upgrade

Cisco UCS X210c M7 Server Memory

This 16GB DDR5 4800MHz ECC RDIMM is built for the Cisco UCS X210c M7 compute node. It delivers registered error-correcting memory for enterprise workloads that require data integrity and system stability. The module operates at 1.1V with CL40 latency and a 1Rx8 configuration using major OEM chips. It is intended for IT professionals upgrading or expanding compatible Cisco server platforms.

Installation and Common Issues

The 288-pin DDR5 RDIMM installs in the server memory slots following the system manual. Registered ECC modules must be populated according to the platform guidelines for correct operation. A frequent issue occurs when mixing registered and unbuffered memory or using non-qualified speeds, which prevents the system from posting. Always verify the exact part number MR38400-618K1 against the Cisco qualified vendor list before installation.

Registered ECC Compatibility Requirement

This module only works in systems that support DDR5 registered ECC RDIMMs with a 1Rx8 organisation. It will not function in desktop motherboards, laptops, or servers requiring unbuffered or load-reduced DIMMs. Buyers needing non-ECC memory, different ranks, or other form factors must select a different product.
