NEMIX RAM
32 GB DDR4 3200 ECC registered RDIMM for Thinkmate GPU-optimised servers
This 32 GB DDR4 3200 registered DIMM adds ECC error correction to ThinkMate GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU servers. It runs at 1.20 V with CL22 latency and a 2Rx8 organisation. The module uses major OEM Samsung, Micron or Hynix chips on a 288-pin PCB without a heat spreader.
The package contains one 32 GB stick, so administrators can populate empty slots individually instead of matching pairs. Registered buffering reduces electrical load on the memory controller, helping stability in dense configurations. No additional software or cables are included; the upgrade is purely the memory module itself.
This DIMM fits the two listed ThinkMate models that require DDR4 3200 registered ECC memory. Systems that need unbuffered UDIMMs, a different voltage, a higher speed grade or non-ECC modules cannot use this part. Buyers with other server platforms should verify their qualified-vendor list before ordering.

No firmware update is required; the registered ECC module is designed for direct compatibility with the listed THINKMATE GPU-optimised servers.
The memory controller's temperature threshold is reached before the DRAM itself, since the module has no heat spreader to move heat away from the chips.
At 1.20 V the module consumes roughly 3–4 W under sustained load, and the registered buffer adds only a few hundred milliwatts.
