NEMIX RAM
Eight 16 GB DDR4-3200 ECC registered DIMMs totalling 128 GB at CL22 and 1.2 V for Tyan Thunder HX FT83A-B7129
This 128GB kit contains eight 16GB DDR4 3200 registered ECC RDIMMs validated for the Tyan Thunder HX FT83A-B7129 platform. It targets administrators who need maximum supported capacity on this specific server board.
Each module runs at 1.20V with CL22 latency and uses 288-pin DDR4 RDIMM form factor. The registered buffer and ECC circuitry provide signal integrity and error correction required for continuous server workloads. No heat spreaders are fitted, so airflow across the DIMM slots must be maintained by the chassis design.
The upgrade is worthwhile when the board currently runs below 128GB or at speeds lower than 3200 MT/s and the workload benefits from additional ECC-protected capacity. It does not suit systems that require unbuffered UDIMMs or a different DDR generation.

The kit is rated DDR4 3200 PC4-25600; actual speed depends on the Tyan FT83A-B7129 memory controller and installed processor, so the board may run the modules at a lower supported rate.
The kit uses standard 288-pin DDR4 RDIMM modules that install in the board's DDR4 DIMM slots; the FT83A-B7129 manual confirms the slot spacing and maximum module height for the chassis.
Populate all eight slots following the FT83A-B7129 population guide — typically one module per channel in the prescribed order — then enable ECC in BIOS; the step most often missed is verifying the ECC setting after boot.
