Eight 8 GB registered ECC DDR4 modules running at 3200 MHz CL22 for Tyan TS75-B8252 servers
This 64 GB kit contains eight 8 GB DDR4 3200 registered ECC RDIMMs built for the Tyan Transport HX TS75-B8252. It targets server and workstation administrators who need validated, high-capacity memory for mission-critical workloads. The modules are tested under load to ensure stability in that specific platform.
Each module runs at 1.20 V with a CAS latency of 22 and no heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping to keep power draw predictable during sustained operation. Noise is determined entirely by the host system’s fan curves.
The 288-pin RDIMM form factor fits the Tyan TS75-B8252’s DDR4 slots directly and requires a motherboard that supports registered ECC memory. Populating all channels with this kit frees expansion slots for other add-in cards while delivering the full 64 GB capacity. Compatibility is limited to systems qualified for DDR4 3200 registered ECC modules.

Power down the server, open the chassis, and seat each module firmly until the retention clips click; the step often missed is populating all eight slots in the exact channel order the motherboard manual specifies.
No scheduled maintenance is required; if a module fails the ECC logic will flag correctable errors, and the only action is replacing the faulty stick.
The CAS 22 latency and registered buffer add fixed overhead, so memory latency becomes the bottleneck before bandwidth or thermal limits are reached.
