64 GB DDR4 ECC RDIMM kit

This NEMIX RAM kit delivers 64 GB of DDR4 3200 registered ECC memory across eight 8 GB modules. It is built for ThinkMate STX-WS-QS12-12E2 and STX-WS-QE36-14E2 servers and workstations that require registered DIMMs with error correction.

CL22 latency and 1.20 V operation

The modules run at CL22 timings and the standard 1.20 V DDR4 voltage, providing 3200 MT/s throughput for typical server workloads. Capacity scales to 64 GB with this kit; larger memory requirements would need additional DIMM slots or higher-density modules.

Passive cooling and registered buffering

Without heat spreaders, the RDIMMs rely on chassis airflow for thermal management. Registered buffering reduces electrical load on the memory controller, supporting stable operation in multi-module configurations at the rated 3200 MT/s speed.

Questions about this item

Will this 64 GB DDR4 3200 CL22 ECC RDIMM kit work alongside existing DDR4 modules in my Thinkmate STX-WS-QS12-12E2?

The kit uses DDR4 3200 (PC4-25600) at 1.20 V with CL22 timing and registered ECC. For stable operation, any modules already installed must match those specifications exactly, including registered buffering and ECC support.

How can I confirm the 8 x 8 GB kit is running at 3200 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory speed reads 3200 MT/s, the voltage shows 1.20 V and the ECC status is reported as enabled or active.

What comes in the box and is anything else required for installation?

The package contains the 64 GB (8 x 8 GB) DDR4 3200 CL22 ECC RDIMM kit only. No heat spreaders, tools or additional cables are included.
