NEMIX RAM
128 GB DDR5-5600 ECC registered DIMM with CL46 latency and 1.1 V operation for Cisco servers
This 128GB DDR5 5600 module is built for Cisco servers that require registered ECC memory. It targets IT teams maintaining compatible UCS platforms where stability under sustained load is the priority.
The single specification that decides fit is the 4Rx4 registered ECC RDIMM organisation at CL46 latency. Only systems qualified for this exact rank and buffer configuration will recognise the full 128GB capacity.
Operating at 1.1V without a heat spreader, the module relies on server chassis airflow for cooling. Registered buffering adds minimal overhead, so power draw stays low during typical enterprise workloads.

The module runs at DDR5 5600 (PC5-44800), delivering that data rate when the platform memory controller is configured for 5600 MT/s.
The 288-pin registered DDR5 form factor connects to the server memory bus and the registered buffer allows the platform to populate multiple modules per channel at the rated speed.
It fits a standard 288-pin DDR5 RDIMM socket and has no heat spreader, so it clears typical server DIMM spacing.
