NEMIX RAM
16 GB DDR4 3200 ECC registered DIMM for Thinkmate servers, CL22 2Rx8 at 1.2 V
This 16 GB registered DIMM runs at DDR4-3200 with CL22 latency and 1.2 V operation. It uses a 2Rx8 organisation and 288-pin form factor. The module is validated for Thinkmate GPX-XS12-24S3-8GPU GPU-optimised servers. ECC and register buffering protect data integrity in multi-socket workloads.
Buyers expanding a Thinkmate GPX-XS12-24S3-8GPU system can add capacity without mixing unbuffered modules. Systems that require unbuffered UDIMMs or non-ECC memory cannot use this RDIMM. Workstations limited to 8 GB per slot or consumer motherboards without registered support should look elsewhere.
The registered buffer reduces electrical loading on the memory bus during continuous throughput. ECC corrects single-bit errors that accumulate under long-running compute tasks. CL22 timing and 1.2 V voltage remain stable across extended duty cycles in the validated Thinkmate platform.

Yes, the module is an ECC registered RDIMM, so the host system must support both ECC error correction and registered buffering for the memory to operate.
The memory will down-clock to match the lowest-speed module present; all sticks then run at that common frequency with the loosest latency among them.
Check the system BIOS or UEFI memory information screen — it should show 16 GB total capacity, DDR4 3200 speed, ECC active, registered mode, and a 2Rx8 organisation.
