NEMIX RAM
A 48 GB DDR4 ECC registered server memory kit of six 8 GB modules running at 3200 MHz with CL22 latency and 1.2 V operation
This NEMIX RAM kit provides 48GB of DDR4 3200 registered ECC memory across six 8GB modules. It is built for THINKMATE GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU GPU-optimised servers that require registered DIMMs. The CL22 latency and 1.20V operation match the platform specifications. System administrators upgrading these specific Thinkmate servers will find a direct compatibility match.
Each module uses a 288-pin RDIMM form factor with 1Rx8 organisation and major OEM chips from Samsung, Micron or Hynix. Registered buffering reduces electrical load on the server memory controller, supporting stable operation in multi-DIMM configurations. The absence of heat spreaders allows tight spacing in dense GPU-optimised chassis. Installers should verify the motherboard DIMM population rules for six-module kits.
This kit upgrades systems running unbuffered non-ECC memory or smaller registered configurations that lack error correction. The jump is worthwhile when workloads demand data integrity across 48GB of capacity in the supported Thinkmate GPU servers. Builders needing consumer UDIMMs, different voltages or capacities outside the 6x8GB arrangement should look elsewhere.
