Capacity and purpose

This kit provides 768GB of DDR4 ECC registered memory across twelve 64GB modules for the Thinkmate GPX-QN6-42E2-8NVLINK GPU-optimised server. It targets administrators who need maximum capacity for virtualisation, large datasets or memory-intensive compute workloads. The 4Rx4 organisation and CL22 latency suit registered server platforms that require registered DIMMs. Buyers seeking non-ECC or unbuffered memory for desktop boards should look elsewhere.

Build and connectors

Each module is a 288-pin DDR4 RDIMM operating at 1.20V without a heat spreader, relying on server chassis airflow for cooling. The registered design places a register on the command bus to reduce electrical load on the memory controller, which is mandatory for the target platform. Twelve modules must populate the correct slots in matched sets to achieve the rated 3200 MT/s speed and maintain signal integrity. Systems that do not support registered ECC RDIMMs cannot use this kit.

Compatibility checks

Verify that the Thinkmate GPX-QN6-42E2-8NVLINK motherboard accepts twelve 4Rx4 registered DIMMs and that the BIOS is current enough to initialise the full 768GB configuration. Confirm the CPU memory controller supports the stated speed and rank population rules for this density. Ensure the chassis has twelve free DDR4 slots and sufficient airflow for modules without spreaders. Orders for other server models or workstation boards will not be compatible.

Questions about this item

What DDR4 standard and speed does this 12-module kit run at?

The kit uses PC4-25600 DDR4 3200 modules rated at CL22 latency and 1.20 V.

What physical slot and module count does the 768 GB kit require?

It needs twelve free 288-pin DDR4 RDIMM slots, one per 64 GB 4Rx4 module.

How are the registered ECC modules installed, and what step is often missed?

Align the notch, press firmly until both retention clips click, then verify the BIOS recognises all twelve 4Rx4 ranks.
