THINKMATE Compatible Server Memory

This NEMIX RAM module delivers 128GB of DDR5 4800 registered ECC memory in a single 288-pin RDIMM. It operates at 1.1V with CL40 latency and a 4Rx4 rank configuration. The module is validated for THINKMATE GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX GPU-optimised servers. Major OEM chips from Samsung Micron or Hynix are used.

Suited for capacity-hungry server workloads

IT teams expanding memory in the listed THINKMATE platforms will find a direct-fit upgrade. Builders needing unbuffered UDIMMs or non-ECC modules for consumer motherboards cannot use this registered ECC RDIMM. Systems limited to lower maximum densities per slot or requiring different pin counts should look elsewhere.

128GB single-module density headroom

One module provides 128GB of addressable memory, letting populated slots reach high totals quickly. The DDR5 4800 interface supplies 38400 MB/s bandwidth for multi-GPU compute and large dataset processing. Workloads exceeding per-slot limits or demanding speeds above 4800 MT/s will exceed this module's rated capability.

Questions about this item

Does my Thinkmate GPX-QH24-24E4-8GPU server require a specific BIOS version to recognise this 4800MHz DDR5 RDIMM?

The module is validated for the Thinkmate GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX platforms; install it in a supported DIMM slot and the system will detect the 4800 speed at 1.1V.

Can I mix this 4Rx4 ECC RDIMM with existing 2Rx4 modules in the same Thinkmate server?

This is a 4Rx4 registered ECC DIMM; mixing ranks is not recommended and the server's memory population rules should be followed for stable operation.

How do I confirm the memory is running at the rated 4800MHz CL40 after installation?

Enter the BIOS or use a hardware information utility; the memory should report DDR5-4800, CAS latency 40, 1.1V and ECC active.
