256 GB DDR4 ECC registered server memory kit with sixteen 16 GB modules at 3200 MHz CL22 for Tyan GC68A-B8036
This 256GB kit contains sixteen 16GB DDR4 3200 modules built for the Tyan Transport CX GC68A-B8036. Registered ECC RDIMM design targets enterprise servers and workstations that require error correction and signal buffering. Each module runs at 1.2V with CL22 latency and a 2Rx8 organisation. The kit delivers 256GB total capacity across all populated slots.
Registered buffering reduces electrical load on the memory controller, allowing the full 16-module population without signal degradation. The 288-pin DDR4 RDIMM form factor fits only motherboards wired for registered ECC memory; standard unbuffered desktop boards will not accept these modules. No heat spreaders are fitted, so airflow across the DIMM rows must be managed by the chassis. Compatibility is validated for the specified Tyan platform.
All modules undergo rigorous stress testing under load before shipment to verify reliability in continuous operation. ECC circuitry corrects single-bit errors and detects multi-bit errors during extended compute tasks, preventing silent data corruption. The 1.2V operating voltage maintains consistent power draw across long-running workloads. Registered architecture sustains signal integrity when every slot is occupied at the rated 3200 MT/s speed.

CL22 is the rated CAS latency for these DDR4 3200 modules; sustained throughput will depend on the Tyan GC68A-B8036 memory controller and the number of populated channels.
Each 16 GB 2Rx8 RDIMM runs at 1.20 V without a heat spreader; total power scales with all 16 modules active, so chassis airflow must handle the combined thermal load.
The kit is validated for the Tyan Transport CX GC68A-B8036; the board must support 16 × 16 GB DDR4 3200 ECC RDIMMs and have enough DIMM slots to accept the full kit.
