ThinkMate GPX-QN6 Server Memory Upgrade

This 128GB kit contains eight 16GB DDR4 3200 registered ECC RDIMMs validated for ThinkMate GPX-QN6-42E2-8NVLINK GPU-optimised servers. It targets IT teams expanding memory capacity in multi-GPU compute nodes that require registered modules with error correction.

Replacing Smaller Registered Kits

The kit replaces lower-capacity RDIMM sets when workloads exceed the memory bandwidth or footprint of the existing configuration. The jump is worth it when virtualisation density, GPU-accelerated analytics or large-model training demand the full 128GB at PC4-25600 speed with CL22 latency.

Eight-Slot Population at 1.2V

Eight 288-pin slots must be populated with 2Rx8 modules running at 1.2V; the registered buffer reduces electrical load on the server memory controller. No heat spreaders are fitted, so chassis airflow must handle thermal dissipation for sustained GPU-compute loads.

Questions about this item

Will eight 288-pin DDR4 RDIMM slots accept this 128GB kit?

Yes, the kit contains eight 16GB modules that fit standard 288-pin DDR4 RDIMM sockets in the ThinkMate GPX-QN6-42E2-8NVLINK server.

What is the correct slot-population order for eight registered DIMMs?

Follow the motherboard manual channel map; populate each channel identically with the 2Rx8 registered modules to enable quad-channel operation.

Do these ECC RDIMMs require periodic replacement?

No scheduled replacement is needed; the modules run at 1.20V with major OEM chips and are covered by a lifetime replacement warranty.
