NEMIX RAM
64GB kit of eight 8GB DDR4 3200 ECC registered DIMMs at 1.2V CL22 for Tyan FT83A-B7129 servers
This 64GB kit contains eight 8GB DDR4 3200 registered ECC RDIMMs validated for the Tyan Thunder HX FT83A-B7129 server platform. It targets administrators upgrading memory capacity in that specific system.
The kit supplies eight identical 1Rx8 modules at 1.2V CL22 so every slot receives the same ranked, registered DIMM. This removes the guesswork of mixing capacities or ranks and lets the board initialise all channels in a single step.
Confirm the FT83A-B7129 has eight available DDR4 RDIMM slots and that its firmware supports a full 64GB population at 3200 MT/s. Systems with fewer slots or lower per-channel limits will not accept the complete kit.

The kit fills eight slots with 8 GB 1Rx8 modules; expanding past 64 GB requires replacing modules with higher-capacity DDR4 RDIMMs that the Tyan FT83A-B7129 platform accepts.
CAS latency 22 at 3200 MT/s sets the timing ceiling, while the registered buffer adds one cycle; sustained bandwidth is therefore bound by the DDR4 3200 interface and CL22 timing.
Each 8 GB 1Rx8 module operates at 1.20 V without a heat spreader; total kit power scales with all eight DIMMs active, and airflow across the bare PCBs manages thermals in the Tyan chassis.
