NEMIX RAM
192 GB DDR5 registered ECC server memory kit with twelve 16 GB modules at 4800 MT/s CL40 1.1 V for Cisco UCS X410c M7 compute nodes
This 192GB DDR5 kit uses twelve 16GB registered ECC modules built for the Cisco UCS X410c M7 compute node. It targets IT teams expanding memory capacity in validated server configurations.
Registered DDR5 modules operate at 1.1V without onboard heat spreaders, relying on server chassis airflow for cooling. Power draw scales with the 4800 MT/s data rate and 1Rx8 organisation under typical enterprise workloads.
The kit delivers 192GB at DDR5 4800 with CL40 latency in a 288-pin RDIMM form factor. Buyers needing non-ECC unbuffered DIMMs or a different capacity per module must select another part.

Power down the node, open the chassis, align each 288-pin module with its slot, press firmly until the ejector tabs click, then verify all 12 modules appear in BIOS before booting the OS.
No scheduled maintenance is required; if a module fails the ECC logic will log correctable errors, and the faulty 16GB stick can be swapped individually without replacing the full 12-module kit.
The CAS latency of CL40 at 4800 MT/s sets the timing ceiling; sustained throughput is bounded by this latency figure rather than voltage or thermal throttling.
