NEMIX RAM
Adds 64 GB DDR4 3200 ECC registered memory to compatible Thinkmate servers
This 64 GB DDR4 3200 module is built for Thinkmate STX-TN-XE36-24S3 and STX-TN-XE24-24S3 NAS servers. It delivers registered ECC memory for workloads that require error correction and data integrity. The single 64 GB stick fits systems designed for high-capacity registered DIMMs. It is not suited for consumer desktops or laptops that use unbuffered memory.
The module uses a 288-pin RDIMM form factor with 4Rx4 chip organisation and operates at 1.20 V. It has no heat spreader, so airflow in the server chassis handles cooling. Registered buffering reduces electrical load on the memory controller, allowing larger memory populations. Buyers needing low-profile unbuffered DIMMs or modules with integrated heat spreaders should look elsewhere.
The DDR4 3200 interface runs at CL22 latency with a PC4-25600 data rate. Registered ECC operation adds a clock cycle for command buffering, which affects latency-sensitive tasks. Maximum capacity per channel and supported ranks depend on the server memory controller, not the module alone. Systems limited to lower speeds, unbuffered DIMMs, or different rank configurations cannot use this memory.

The module is rated DDR4 3200 (PC4-25600) and is listed as compatible with the Thinkmate STX-TN-XE36-24S3 and STX-TN-XE24-24S3 NAS servers.
Yes, it uses the standard 288-pin DDR4 RDIMM form factor with 4Rx4 organisation, matching the slots in the specified Thinkmate systems.
Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that all 64 GB are detected at 3200 MHz with ECC active.
