NEMIX RAM
Eight 16 GB DDR4 ECC registered DIMMs running at 3200 MHz with CL22 latency for Thinkmate servers
This 128GB kit contains eight 16GB DDR4 3200 registered DIMMs built for Thinkmate STX-WS-QS12-12E2 and STX-WS-QE36-14E2 platforms. Each module runs at 1.2V with CL22 latency and 2Rx8 organisation. The kit targets administrators who need validated ECC memory for Windows NAS or workstation deployments. It is not suited for consumer desktop boards that require unbuffered UDIMMs.
Registered signalling reduces electrical load on the memory controller, allowing all eight slots to run at 3200 MT/s without timing relaxation under continuous multi-threaded workloads. ECC single-bit correction protects data integrity during long render, virtualization or database jobs. The 2Rx8 density keeps rank count manageable for the platform's memory controller. Modules lack heat spreaders, so chassis airflow must handle thermal dissipation during extended load.
The 288-pin DDR4 RDIMM keying prevents accidental insertion into UDIMM-only slots, eliminating a common mis-installation risk. Samsung, Micron or Hynix major-OEM DRAM chips are used across the kit. No heat spreader means modules fit tight DIMM spacing in 1U or 2U Thinkmate chassis without clearance conflicts. Buyers needing unbuffered memory or consumer XMP profiles should select a different product line.

Each module operates at 1.20 V, the standard DDR4 voltage, keeping power draw low during all-day workloads.
The board needs eight 288-pin DDR4 RDIMM slots that support ECC registered memory at PC4-25600 speed.
Mixing ranks and latencies is not recommended; for stability, populate all eight slots with this matched 2Rx8 CL22 kit.
