NEMIX RAM
2 TB kit of 16 registered DDR4 ECC RDIMMs running at 3200 MT/s CL22 1.2 V for Tyan Thunder HX FT83A-B7129 servers
This 2TB memory kit contains sixteen 128GB registered DIMMs built for the Tyan Thunder HX FT83A-B7129 server platform. Each module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V and provides ECC error correction. The 4Rx4 organisation and 288-pin RDIMM form factor are designed for multi-socket server boards that require registered memory. Samsung, Micron or Hynix DRAM chips are used depending on supply.
Administrators expanding a Tyan Thunder HX FT83A-B7129 to its full memory capacity will find this kit matches the board's registered ECC requirements. Systems that need unbuffered UDIMMs, non-ECC modules, lower densities or a different pin count cannot use these DIMMs. Workstations or consumer motherboards lacking registered ECC support are also incompatible.
Sixteen 128GB ranks deliver 2TB total capacity, giving ample headroom for dense virtualisation clusters, large in-memory databases and high-throughput compute nodes. The CL22 timing and 3200 MT/s data rate keep latency predictable under sustained load. Workloads exceeding 2TB per system or requiring faster DDR5 speeds will outgrow this configuration.

Yes, the kit uses 288-pin DDR4 RDIMM modules, so the motherboard must provide DDR4 RDIMM slots.
Mixing 4Rx4 registered modules with lower-rank RDIMMs is possible only if the platform's memory controller and BIOS support mixed-rank populations.
Enter the system firmware at boot and verify that 2 TB total capacity is reported with ECC status shown as enabled.
