Cisco UCS X410c M7 memory kit

This NEMIX RAM kit supplies 256GB across sixteen 16GB DDR5 4800 RDIMMs built for the Cisco UCS X410c M7 compute node. Each module is a 1Rx8 registered ECC part running at 1.10V with CL40 latency. The kit targets IT teams scaling memory capacity in validated Cisco server platforms.

Check DDR5 RDIMM slot count and maximum capacity

Verify that the X410c M7 has sixteen available 288-pin DDR5 RDIMM slots and that its firmware supports the full 256GB configuration at 4800 MT/s. Confirm the system accepts 1Rx8 registered ECC modules at 1.1V before ordering. Mixing ranks or voltages can prevent boot or reduce stability.

Suits Cisco UCS X410c M7 capacity upgrades

This kit fits administrators expanding a single compute node to its supported memory limit with matched modules. It is not for desktop PCs, laptops, or workstations that require unbuffered memory. Buyers needing non-ECC parts, lower capacities, or different form factors should look elsewhere.
