NEMIX RAM
A 64 GB DDR4 2666 MHz ECC LRDIMM module with CL19 latency, 4Rx4 organisation and 1.2 V operation for Thinkmate GPU-optimised servers
This NEMIX RAM module provides 64GB of DDR4 2666 ECC LRDIMM memory built for the Thinkmate GPX-QT8-24E2-8GPU server. The load-reduced design supports dense configurations in GPU-optimised systems. It targets administrators expanding memory capacity for virtualisation or compute workloads.
Confirm the server has a free 288-pin DDR4 slot and check the platform's qualified vendor list for 4Rx4 LRDIMM support at 2666 MT/s. The module runs at 1.2V with CL19 latency. Mixing ranks or speeds can prevent boot or reduce performance.
The bare PCB uses major OEM chips from Samsung Micron or Hynix and omits a heat spreader to fit tight DIMM spacing. The 288-pin LRDIMM form factor reduces electrical load on the memory controller. Handle by the edges and seat firmly until the retention clips engage.

The package contains one 64GB DDR4 2666MHz ECC LRDIMM module (part ML21300-944K1). No additional components are included; buy extra modules separately to reach your desired total capacity.
This specific 64GB 4Rx4 LRDIMM at 2666MHz CL19 1.20V is the validated configuration for that server; select additional identical modules to scale memory in matched sets.
It provides DDR4-2666 bandwidth with ECC error correction and load-reduced signalling at CL19 latency, enabling stable high-capacity operation in the Thinkmate GPU-optimised platform.
