System-Specific DDR5 RDIMM Kit

This 384 GB kit contains twelve 32 GB DDR5 4800 CL40 ECC registered DIMMs built for the Thinkmate GPX-XH8-22S4-8GPU GPU-optimised server. It targets IT teams who need maximum registered memory capacity in that exact platform.

Upgrade from smaller registered sets

Replacing a partial population with this full 12-module kit raises total capacity to 384 GB and keeps every slot running at the rated 4800 MT/s speed. The jump is worth it when workloads exceed the current memory ceiling and the server board supports the full complement of registered DIMMs.

Straightforward module installation

Each 288-pin RDIMM seats in the standard DDR5 server slots; no heat spreaders are present, so clearance is not a concern. The usual pitfalls are mixing registered and unbuffered modules, populating slots in the wrong order, or failing to update the system BIOS before the upgrade.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the ThinkMate GPX-XH8-22S4-8GPU motherboard slots?

Yes, the 288-pin DDR5 RDIMM modules are the correct physical form factor for the ThinkMate GPX-XH8-22S4-8GPU server motherboard memory slots.

What is the correct installation sequence for the 12 modules across the CPU channels?

Populate all 12 slots evenly across the processor memory channels following the ThinkMate GPX-XH8-22S4-8GPU manual to enable full bandwidth and registered ECC operation.

Will the Samsung, Micron or Hynix DRAM chips require firmware updates or replacement over time?

The major OEM DRAM chips do not require firmware updates; replace a module only if diagnostics report a correctable or uncorrectable ECC error on that specific stick.
