Capacity and Form Factor

This NEMIX RAM module delivers 128GB of DDR5 memory in a single 288-pin RDIMM. It operates at 4800MT/s with a CL40 latency and 1.1V voltage. The 4Rx4 registered ECC design targets server and workstation platforms requiring high-density error-correcting memory.

Platform Compatibility Checks

Verify that your motherboard supports DDR5 RDIMM modules and accepts 4Rx4 registered ECC configurations. Confirm the system qualifies 128GB single-rank density per slot and runs at 1.1V. Consult the board vendor memory QVL for the specific part number MR38400-744K1 before ordering.

Thermals Noise and Power

The module runs at the standard DDR5 1.1V without a heat spreader, relying on chassis airflow for cooling. Registered buffering adds minimal latency overhead while reducing electrical load on the memory controller. Power draw scales with the 4800MT/s data rate and 4Rx4 organisation during sustained server workloads.
