NEMIX RAM
128 GB of DDR4 ECC registered server memory in a four-module kit running at 3200 MHz with CL22 latency and 1.2 V operation
This 128GB kit contains four 32GB DDR4 3200MHz ECC RDIMM modules built for the Tyan Transport HX TS75-B8252 server platform. Each module runs at 1.2V with CL22 latency and a 2Rx8 organisation. The registered design adds signal buffering for stable operation in multi-slot configurations.
IT teams adding memory to this specific Tyan server will find the kit validated for compatibility and stress-tested under load. Builders working with other motherboards, desktop platforms, or systems requiring unbuffered DIMMs should select a different kit matched to their hardware.
The 3200MHz speed and CL22 timing handle virtualisation workloads, database buffers and large dataset caching within the platform limits. Workloads demanding higher frequencies, lower latencies or greater density per slot will exceed what this DDR4 3200 registered configuration can deliver.

Yes, the board must accept DDR4 3200 PC4-25600 registered ECC RDIMMs at 1.2 V with 2Rx8 organisation and 288-pin form factor.
The system will run all modules at the speed and timings of the slowest installed kit, so existing slower DDR4 ECC RDIMMs will limit these 3200MHz modules.
Check the BIOS memory summary or use a tool such as dmidecode to confirm 128GB total, 3200MT/s data rate, registered ECC type and CL22 timings.
