384GB DDR5 ECC RDIMM kit for Thinkmate GPU servers

This 384GB kit contains six 64GB DDR5 4800 CL40 registered ECC RDIMMs built for the Thinkmate GPX-XH8-22S4-8GPU GPU-optimised server. The modules run at 1.1V and use 2Rx4 organisation with major OEM Samsung, Micron or Hynix chips. It targets IT teams expanding memory capacity in that specific platform.

Installing the six modules into the server DIMM

Each 288-pin RDIMM seats in the standard DDR5 server slots; the registered buffer and ECC function require a motherboard that supports registered memory. The kit ships without heat spreaders, so airflow across the modules must be sufficient. A common issue is mixing these registered DIMMs with unbuffered modules, which prevents the system from posting.

Verify your Thinkmate model

Confirm the server is the exact GPX-XH8-22S4-8GPU model before ordering. Check the motherboard manual for the supported DIMM population sequence and maximum capacity per channel. Ensure the BIOS version recognises 64GB 2Rx4 registered DDR5 modules at 4800 MT/s. Systems that require unbuffered or non-ECC memory cannot use this kit.

Questions about this item

How do I verify the kit is running at 4800 MT/s and CL40 after installation?

Check the memory speed and CAS latency in the server BIOS or UEFI; they should show 4800 MT/s and CL40 for each of the six 64 GB modules.

What ships in the package and do I need any extra parts?

The box contains the six 64 GB DDR5 4800 CL40 ECC RDIMM modules that make up the 384 GB kit; no additional components are required for installation.

Which capacity configuration should I choose for the THINKMATE GPU-Optimized Server?

This kit provides 384 GB total via six 64 GB RDIMMs, matching the supported population for the GPX-XH8-22S4-8GPU server.
