NEMIX RAM
A 32 GB dual-channel DDR4-3200 ECC registered DIMM kit built for Tyan Transport HX TN83-B8251 servers
This 32GB kit contains two 16GB DDR4 3200 registered DIMMs with ECC. It is built for the Tyan Transport HX TN83-B8251 server and workstation platform. The modules run at 1.20V with CL22 latency and a 2Rx8 organisation.
Buyers whose motherboard accepts DDR4 ECC RDIMMs and who need 32GB in a matched pair will find this kit validated for the named Tyan system. Systems that require unbuffered UDIMMs, non-ECC memory, or a different DDR generation cannot use these modules.
The dual-rank 2Rx8 layout and registered buffer define how the memory controller addresses each DIMM. Confirm that the Tyan Transport HX TN83-B8251 configuration supports this rank structure and 3200 MT/s registered speed before purchase.

Power down, open the chassis, align each 288-pin RDIMM with the keyed slot, press firmly until both retention clips click, then verify in BIOS that all 32GB at 3200 MT/s are recognised.
The modules have no heat spreader and no moving parts; only occasional dust removal from the gold contacts is required, and ECC corrects single-bit errors without user action.
The CAS-22 latency at 1.20 V is the primary timing constraint; thermal throttling is unlikely without a heat spreader, so latency remains the first bottleneck.
