NEMIX RAM 128GB (4x32GB) DDR5 4800 CL40 ECC RDIMM Cisco UCS X210c M7 memory upgrade

Cisco UCS X210c M7 memory kit

This 128GB kit contains four 32GB DDR5 4800 registered DIMMs built for the Cisco UCS X210c M7 compute node. ECC and registered buffering protect data integrity in multi-socket server workloads. IT teams use it to expand memory capacity for virtualisation, databases and container platforms. The modules run at 1.10V and carry a CL40 latency rating.

DDR5 4800 registered ECC limits

DDR5 4800 sets the maximum transfer rate at 38400 MT/s, so bandwidth scales with the memory controller rather than the module. Registered signalling adds one cycle of address latency, which the platform absorbs for signal integrity at full population. ECC corrects single-bit errors but cannot recover from multi-bit failures. Mixing ranks or speeds would force the controller to the lowest common denominator.

128GB capacity and headroom

Four 32GB 1Rx4 modules fill four slots and deliver 128GB of addressable memory for dense VM deployments. The 1Rx4 organisation keeps electrical loading low, leaving headroom for the memory controller to maintain 4800 MT/s across all channels. Workloads that exceed 128GB or require higher frequencies will need a platform with more slots or faster DDR5 speeds.
