NEMIX RAM
Eight 16 GB DDR4 ECC registered DIMMs running at 3200 MT/s CL22 1.2 V for ThinkMate GPU-optimised servers
This kit supplies 128GB of DDR4 memory across eight 16GB registered DIMMs. It is built for Thinkmate GPX-PS4-12A1 GPU-optimised servers that require ECC error correction and registered buffering for stable operation under sustained workloads.
The modules run at DDR4 3200 (PC4-25600) with a CL22 latency and 1.20V voltage. Registered ECC DIMMs must be used on motherboards that support registered memory and ECC functionality; they will not function in consumer platforms that lack these features. Mixing registered and unbuffered DIMMs is not supported.
Installing eight DIMMs fills every available slot on most compatible Thinkmate boards, so the memory controller operates at maximum electrical load. Populate slots in the order specified by the server manual to ensure correct channel population. Verify BIOS revision requirements before installation, as some revisions are needed for full 128GB recognition.

The kit provides 128GB total across eight 16GB RDIMMs, matching the 2Rx8 rank structure and CL22 timing validated for the GPX-PS4-12A1 GPU-optimised platforms.
It runs at 3200MT/s with CL22 latency at 1.20V, giving the rated bandwidth while the registered buffer and ECC maintain data integrity under sustained GPU workloads.
The 288-pin DDR4 RDIMM slot caps the module at 3200MT/s and 16GB per rank; the registered design allows the eight-module population without signal degradation.
