Capacity and form factor

This NEMIX RAM module provides 16 GB of DDR5 memory in a single 288-pin RDIMM. It is built for Thinkmate GPX-QH12-12E4-2GPU GPU-optimised servers and workstations that require registered ECC memory. The 1Rx8 organisation and 1.10 V operation match the platform's native specifications.

Replacing slower or smaller DIMMs

Upgrading from lower-speed DDR5 or from non-ECC unbuffered modules adds error correction and registered signalling for data integrity under sustained load. The jump is worth it when the server runs virtualisation, GPU compute or database workloads that demand maximum uptime and consistent throughput at 4800 MT/s.

Compatibility checklist

Verify that your Thinkmate system accepts DDR5 4800 RDIMMs with CL40 timing and 1.10 V voltage. Confirm the motherboard has free 288-pin slots and that the BIOS supports registered ECC modules of this rank and density. Consult the system manual for population rules before ordering.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the memory slots on my THINKMATE GPX-QH12-12E4-2GPU server?

Yes — the module is a 288-pin DDR5 RDIMM built to the DDR5 4800 (PC5-38400) standard, which is the slot type used by that server.

What is the correct order for seating the 1Rx8 registered DIMM so the ECC function activates?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then power on and verify ECC status in the BIOS.

How do I know when the 1.10 V Samsung, Micron or Hynix chips should be replaced?

Run periodic memory diagnostics; if correctable ECC error counts rise steadily or the system logs uncorrectable errors, plan a replacement.
