System-specific DDR4 ECC RDIMM kit

This NEMIX RAM kit delivers 768 GB across six 128 GB modules built for the Thinkmate GPX-QN6-42E2-8NVLINK platform. Each module is a 288-pin DDR4 registered DIMM with ECC and a 4Rx4 organisation. The kit targets IT teams expanding memory capacity in GPU-optimised Thinkmate servers and workstations.

Pre-installation checks for Thinkmate servers

Verify that the server has six free DDR4 RDIMM slots and that the BIOS revision supports 128 GB 4Rx4 modules at the rated speed. Confirm the memory population rules for the specific CPU configuration to ensure all six modules can be active simultaneously. Ensure the operating system and hypervisor licences allow the resulting total capacity.

Thermals power and acoustic profile

Modules operate at 1.2 V without heat spreaders, relying on the server’s directed airflow for cooling. Registered buffering and ECC add minimal latency overhead while maintaining signal integrity under sustained load. Power draw scales with the number of populated slots and the 3200 MT/s data rate during normal operation.
