Eight-module 64 GB DDR4 3200 CL22 ECC registered kit for Tyan TS65-B8036 servers
This 64GB kit provides eight 8GB DDR4 3200 registered ECC modules built for the Tyan Transport SX TS65-B8036 server. Each stick runs at PC4-25600 with CL22 latency and 1.2V operation. The 1Rx8 organisation suits the platform’s registered memory slots. System administrators upgrading that specific motherboard receive a validated configuration.
Registered ECC RDIMMs operate at the standard 1.2V DDR4 voltage, keeping power draw predictable in a populated server chassis. No heat spreaders are fitted, so airflow through the DIMM bays handles cooling directly. The modules add minimal acoustic load because they have no moving parts and rely on existing case fans.
Eight 288-pin RDIMMs fill the corresponding registered DIMM sockets on the TS65-B8036 board. The kit occupies all slots in an eight-channel layout, leaving no free sockets for further expansion on that motherboard. Builders who need more capacity must choose a different platform or higher-density modules. Compatibility is confirmed for the listed Tyan system only.

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click, then populate all eight slots following the motherboard manual's channel order.
The modules have no heat spreaders and no moving parts; keep server airflow clean and monitor ECC correctable error counts in the BMC, replacing any stick that shows rising error rates.
Under continuous heavy load the fixed CL22 timing becomes the bottleneck before bandwidth saturates, so latency-sensitive workloads hit the timing ceiling first.
