Capacity & Configuration

This kit provides 512GB of DDR4 memory across four 128GB RDIMM modules. It is built for servers and workstations that require maximum registered ECC capacity in a single population. The 4Rx4 organisation and CL22 timing suit heavy multi-threaded workloads such as virtualisation, in-memory databases and large-scale rendering.

Registered ECC Headroom

Registered buffering and on-die ECC protect data integrity under sustained load, while the 3200MT/s rating delivers PC4-25600 bandwidth for memory-bound tasks. The kit runs at 1.2V, keeping power draw predictable. Capacity tops out at the platform limit, so further expansion requires a motherboard with additional DIMM slots or higher-density modules.

Tyan Transport SX Integration

Designed specifically for the Tyan Transport SX TS65-B8036, the modules populate 288-pin DDR4 slots without extra configuration. No heat spreaders are fitted, so airflow in dense chassis remains unobstructed. Builders needing non-ECC memory, consumer form factors or speeds beyond DDR4-3200 should look elsewhere.

Questions about this item

Will these 4Rx4 128GB RDIMMs run at DDR4 3200 CL22 alongside older DDR4 modules I keep in the Tyan TS65-B8036?

The kit is validated for the Tyan Transport SX TS65-B8036. Mixing ranks or speeds can force the platform to run all channels at the lowest common rate and may prevent the 4Rx4 modules from initialising.

How can I verify the 512GB kit is operating at 3200 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory frequency shows 3200 MT/s, the CAS latency reads CL22 and the ECC status is reported as enabled for all four DIMMs.

Does the package contain only the four 128GB RDIMMs or are additional parts such as heat spreaders included?

The box includes the 512GB kit of four 128GB 288-pin DDR4 ECC RDIMMs. No heat spreaders or other accessories are supplied.
