System-Specific Server Memory Kit

This 128 GB kit provides two 64 GB DDR4 3200 ECC registered DIMMs validated for ThinkMate GPX-XN6-24S3-10GPU GPU-optimised servers. It targets IT teams upgrading memory in that exact platform.

Registered ECC Design for Stability

Each module uses a 4Rx4 organisation with on-board register and ECC circuitry to protect data integrity under sustained loads. The 288-pin DDR4 form factor fits the server's standard DIMM slots without a heat spreader.

128 GB Total Capacity at CL22

The kit delivers 128 GB across two modules running at 3200 MT/s with CAS latency 22 at 1.20 V. Buyers needing a different capacity, speed or rank configuration must select another part.

Questions about this item

What does the DDR4 3200 PC4-25600 rating mean for actual throughput?

The kit runs at 3200 MT/s, giving a peak transfer rate of 25600 MB/s per module; real-world bandwidth will be lower due to latency and controller overhead.

Will the 288-pin RDIMM modules fit in the THINKMATE GPX-XN6-24S3-10GPU server chassis?

Yes, the 288-pin DDR4 RDIMM form factor matches the server's DIMM slots; the 4Rx4 organisation and 1.20V voltage are within the platform's qualified memory list.

How do I install the two 64GB sticks correctly in the Thinkmate server?

Power down, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that 128GB is detected at 3200 MT/s.
