NEMIX RAM 64GB DDR4 3200 ECC RDIMM

This 64GB DDR4 3200 registered DIMM is built for ThinkMate GPX-QT8-24E2-8GPU GPU-optimised servers. It targets IT professionals and system integrators who need validated ECC memory for mission-critical workloads and large-scale virtualisation environments.

Thermals noise and power draw in normal use

The module operates at a standard 1.2V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping maintain stable power draw during sustained multi-threaded compute tasks.

Upgrading from lower-capacity or non-ECC DDR4

This single 64GB 4Rx4 stick replaces multiple smaller RDIMMs to maximise slot utilisation in dense configurations. The jump is worth it when expanding memory capacity for GPU-accelerated workloads that demand high-density registered ECC modules.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in a ThinkMate GPX-QT8-24E2-8GPU server, and what step is often missed?

Power down, open the chassis, align the 288-pin notch with the slot key, press firmly until both latches click, then verify in BIOS that all 64 GB are detected at 3200 MHz; the step often missed is fully seating both latches.

What maintenance or replacement will this ECC registered module need over its service life?

No scheduled maintenance is required; if a correctable error count rises or the module fails, replace the DIMM — the product carries a lifetime replacement warranty.

What limit appears first when this 4Rx4 1.2 V module runs sustained workloads?

The quad-rank organisation and CL22 latency bound sustained throughput before thermal limits, because the module has no heat spreader.
