256 GB DDR4 ECC RDIMM kit for Tyan servers

This registered DDR4 3200 kit supplies 256 GB across two 128 GB modules built for Tyan Transport SX TS65-B8036 systems. It targets IT teams running virtualisation clusters, database servers or high-density compute nodes that require ECC protection and registered signalling. The 4Rx4 organisation and CL22 latency suit workloads where capacity and data integrity outweigh raw frequency.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller, letting all sixteen ranks operate continuously at 3200 MT/s without the signal degradation seen on unbuffered DIMMs. ECC corrects single-bit errors on the fly, preventing silent data corruption during multi-day render jobs or scientific simulations. The 1.20 V operating voltage keeps power draw predictable inside dense 2U or 4U chassis where thermal headroom is limited.

Verify slot count and motherboard qualification list

Confirm the target board exposes enough 288-pin DDR4 RDIMM sockets to accept both 128 GB modules simultaneously. Cross-reference the Tyan qualified-vendor list for the exact TS65-B8036 revision to ensure 4Rx4 density is supported at the rated speed. Check that the BIOS version in use enables registered ECC operation and does not limit total capacity below 256 GB.

Questions about this item

How much power will the 1.2V 4Rx4 registered kit draw during sustained server workloads?

Each module operates at 1.20V DDR4 standard voltage; total system power depends on the platform memory controller and how many slots are populated.

What motherboard features are required for these 288-pin ECC RDIMMs to function?

The host must provide DDR4 RDIMM slots with registered ECC support and a qualified memory controller for 4Rx4 3200 modules.

Can the 3200 CL22 modules share channels with slower DDR4 ECC RDIMMs already present?

Mixed-speed populations are governed by the motherboard BIOS; the memory controller will typically clock all modules to the lowest common speed.
