256 GB kit of two 128 GB DDR4 3200 ECC registered DIMMs for Tyan Thunder HX FT83A-B7129 servers
This 256 GB kit provides two 128 GB DDR4 3200 RDIMMs built for the Tyan Thunder HX FT83A-B7129 server. Each module is registered ECC with a 4Rx4 organisation and runs at 1.2 V with CL22 timing. The 288-pin form factor matches the platform's DIMM slots exactly.
The kit suits administrators populating every slot on a Tyan Thunder HX FT83A-B7129 for virtualisation, database or compute workloads that demand registered ECC stability. Builders using consumer motherboards or platforms that accept only unbuffered UDIMMs cannot use these modules. Systems limited to lower ranks or smaller per-slot limits should look elsewhere.
Two 128 GB RDIMMs deliver the full 256 GB in a minimal slot count, leaving additional DIMM positions free for future expansion if the board supports more than two modules per channel. The 4Rx4 rank structure maximises capacity per module but increases electrical load on the memory controller. Workloads exceeding 256 GB will require additional kits and a platform qualified for higher total memory.

The kit is validated for the Tyan Thunder HX FT83A-B7129 server motherboard and may not function on other platforms.
Mixing different rank configurations such as 4Rx4 with 2Rx4 or 1Rx4 is not recommended and can prevent the server from posting.
Enter the BIOS or UEFI and confirm the memory runs at 3200 MT/s with ECC enabled; the operating system should report 256 GB total with corrected error counting active.
