ThinkMate GPX-XS12-24S3-8GPU DDR4 3200 ECC Kit

This 128GB kit contains four 32GB DDR4 3200 registered DIMMs built for the ThinkMate GPX-XS12-24S3-8GPU server. Each module runs at 1.20V with CL22 latency and 2Rx8 organisation. ECC and registered buffering protect data integrity in multi-GPU workloads.

Suited for GPX-XS12-24S3-8GPU expansion.

The modules are validated for the ThinkMate GPX-XS12-24S3-8GPU platform and similar registered-DDR4 servers. Systems that require unbuffered UDIMMs or non-ECC memory cannot use this kit. Buyers needing consumer desktop RAM should look elsewhere.

288-pin RDIMM form factor; no heat spreader

The 288-pin RDIMM design fits standard registered server slots without additional cooling hardware. Samsung, Micron or Hynix chips are used depending on supply. The package includes only the four memory modules; no cables, software or extra accessories are bundled.

Questions about this item

Does the ThinkMate GPX-XS12-24S3-8GPU require registered ECC RDIMMs for this 128GB kit to function?

Yes, this kit uses registered ECC RDIMMs at 1.2V with CL22 timing, which matches the server's requirement for registered error-correcting memory.

Can I mix these 3200MHz CL22 modules with slower DDR4 already installed in the ThinkMate?

The server will downclock all modules to the speed and latency of the slowest installed memory, so mixing is possible but reduces overall bandwidth.

How can I verify the full 128GB is recognised and running at 3200MHz after installation?

Enter the BIOS or UEFI on boot and check the memory information screen; it should show 128GB total capacity and a 3200MHz operating frequency.
