Tyan TS75-B8252 compatible DDR4 ECC RDIMM kit

This 256 GB kit contains two 128 GB registered DDR4 modules built for the Tyan Transport HX TS75-B8252 platform. Each stick runs at 3200 MT/s with CL22 latency at 1.2 V. The 4Rx4 organisation and ECC registration target server and workstation workloads that demand data integrity.

Upgrading from lower-capacity or non-ECC DDR4 RDIMMs

The jump makes sense when your current configuration hits the motherboard’s rank-per-channel limit or when applications start swapping due to insufficient memory. Replacing smaller unbuffered or single-rank modules with this dual-rank registered pair adds both capacity and error correction in one step.

256 GB headroom for virtualisation

The kit comfortably hosts dozens of virtual machines, large in-memory databases or heavy render queues without paging. Workloads that exceed 256 GB or require faster than 3200 MT/s throughput will need additional DIMM slots or a platform supporting higher memory speeds.

Questions about this item

Will the 288-pin DDR4 RDIMM modules fit the Tyan TS75-B8252 motherboard slots?

Yes, the 288-pin DDR4 RDIMM form factor matches the DIMM slots on the Tyan Transport HX TS75-B8252 motherboard.

What is the correct order for installing the two 128GB modules and which step is commonly missed?

Install one module per channel following the motherboard manual slot order, and the step often missed is fully seating both ends until the retention clips click.

When should the 4Rx4 ECC registered DIMMs be replaced or checked for errors?

Replace modules if the system logs uncorrectable ECC errors or fails memory diagnostics; otherwise they require no scheduled maintenance.
