TYAN S5642AGM3NRE-2T LGA 4189 server motherboard

Single-Socket Server Board for LGA 4189 Xeon

This TYAN S5642AGM3NRE-2T motherboard uses the Intel C621A chipset to support one 3rd Gen Intel Xeon Scalable processor up to 270W TDP. The SSI CEB form factor measures 12 by 10.6 inches and fits compatible rackmount or pedestal chassis. Eight DDR4 channels accept ECC RDIMM or LRDIMM modules at 3200 MT/s for high-capacity memory subsystems.

Suits memory-heavy single-socket workloads.

The board targets virtualisation, database or HPC nodes that need up to 1024GB RDIMM or 2048GB LRDIMM capacity across eight 288-pin slots. Builders requiring two physical CPUs, or who need more than 14 SATA 6.0Gb/s ports, should evaluate other platforms. The single LGA 4189 socket and one-processor limit define the scaling boundary.

Eight-channel DDR4-3200 with 1024GB RDIMM ceiling

Memory bandwidth and capacity are set by the eight-channel controller supporting DDR4 ECC RDIMM and LRDIMM at 3200 MT/s. Maximum validated density reaches 1024GB with standard RDIMMs and 2048GB with LRDIMM or 3DS modules, following Intel DDR4 POR. This spec alone determines whether the board meets a given dataset or VM density target.
