Compatible Server Memory Upgrade

This 16 GB DDR4 module is built for the THINKMATE GPX-QN6-42E2-8NVLINK platform. It delivers ECC protection and registered signalling for stable operation in GPU-optimised server workloads.

Registered ECC with CL22 Timing

The stick runs at DDR4 3200 (PC4-25600) with a CAS latency of 22 and a 2Rx8 organisation. Registered buffering and on-die ECC ensure data integrity under sustained multi-threaded loads.

Low-Voltage Operation Without Heat Spreader

Rated at 1.20 V, the module draws minimal power and runs cool in densely populated DIMM slots. The absence of a heat spreader keeps the profile slim for tight server chassis airflow.

Questions about this item

Will the 3200 MT/s rating hold once the module is installed in the THINKMATE GPX-QN6-42E2-8NVLINK?

The module is rated at DDR4 3200 (PC4-25600). Actual operating speed depends on the server's memory controller and populated DIMM slots; the system will negotiate the highest supported rate automatically.

What does the registered ECC design mean for data integrity and platform compatibility?

Registered ECC RDIMM adds a register between the DRAM and the memory controller and provides error-correcting code, which improves signal integrity and detects single-bit errors — required by the ThinkMate GPU-optimised server platform.

Does the 288-pin RDIMM fit the memory slots on the GPX-QN6-42E2-8NVLINK without a heat spreader?

Yes. The 288-pin DDR4 RDIMM form factor matches the server's DIMM sockets, and the module has no heat spreader, so it clears standard server heatsinks and airflow channels.
