NEMIX RAM
Eight 16 GB DDR4-3200 ECC registered DIMMs totalling 128 GB at CL22 and 1.2 V for the Tyan TS75A-B8252 server board
This NEMIX RAM kit delivers 128 GB of DDR4 3200 ECC registered memory across eight 16 GB modules. It is built for the Tyan Transport HX TS75A-B8252 server platform where registered DIMMs are required. The CL22 latency and 1.2 V operation match the system specification for stable enterprise workloads.
The 288-pin RDIMMs seat in the standard DDR4 slots of the compatible Tyan motherboard without extra tools. Registered modules must populate the correct channels per the board manual; mixing registered and unbuffered DIMMs will prevent boot. No heat spreaders are fitted, so airflow across the modules should be checked after installation.
Each module uses major OEM chips from Samsung, Micron or Hynix and is stress-tested under load before shipping. The registered buffer reduces electrical loading on the memory controller during continuous operation. ECC corrects single-bit errors in real time, maintaining data integrity through extended compute tasks.
