Capacity and purpose

This 256 GB DDR4 ECC RDIMM kit comprises two 128 GB modules built for the THINKMATE GPX-XN6-24S3-10GPU GPU-optimised server. Registered operation and 4Rx4 organisation let the platform address the full capacity without signal degradation. The 1.2 V design matches standard DDR4 server voltage requirements.

Upgrade path

It replaces lower-density DDR4 RDIMM sets or fills empty slots when the workload outgrows the current memory ceiling. The jump is worth it when virtualisation, GPU compute or large-dataset analytics demand more than the existing rank count can deliver. Compatibility is validated for the named Thinkmate chassis only.

Sustained load behaviour

ECC corrects single-bit errors on the fly while registered buffering keeps the command bus stable during continuous throughput. CL22 latency at 3200 MT/s provides predictable timing for long-running jobs. Modules run without heat spreaders, relying on server chassis airflow for thermal management.

Questions about this item

Will the 288-pin DDR4 RDIMM modules fit the Thinkmate GPX-XN6-24S3-10GPU server memory slots?

Yes, the kit uses 288-pin DDR4 RDIMM form factor which matches the registered DIMM slots on the Thinkmate GPX-XN6-24S3-10GPU platform.

What is the correct way to install the two 128 GB modules so the server recognises the full 256 GB?

Populate the two modules in the channel pair specified by the server manual, ensuring each 4Rx4 registered DIMM clicks fully into its 288-pin slot at 1.2 V.

When should the ECC registered DIMMs be replaced if they start logging corrected errors?

Replace modules when the system management log shows a rising corrected-error count that exceeds the platform firmware threshold, indicating chip degradation.
