Server motherboard for Ice Lake Xeon

The TYAN S5642AGMNRE is a single-socket server board built around the LGA 4189 socket for 3rd Gen Intel Xeon Scalable processors up to 270 W TDP. It targets system integrators and data-centre operators who need eight-channel DDR4 memory and PCIe 4.0 expansion in an SSI CEB footprint.

Installation notes and common pitfalls

Eight 288-pin DDR4 slots accept ECC RDIMM, LRDIMM and 3DS variants at 3200 MT/s; populate all eight channels for full bandwidth. PCIe slot wiring is asymmetric: slot 3 runs at x8, slot 4 at x4, and slot 2 is shared through a MUX, so verify card lane requirements before fitting. Two M.2 connectors operate over PCIe 3.0, while the U.2 SFF-8654 connector provides two NVMe ports.

Pre-order compatibility checklist

Confirm your chassis accepts the SSI CEB form factor and can cool a 270 W processor. The board carries 14 SATA 6.0 Gb/s ports with Intel RSTe RAID 0, 1, 10, 5 and a single 1 GbE Intel I210 port; optional dual 10 GbE is a separate add-on. Memory capacity scales to 1024 GB RDIMM or 2048 GB LRDIMM and 3DS modules per Intel POR. Onboard video uses Aspeed AST2500 and audio is Realtek ALC888S 2.1 channel.

Questions about this item

How do I verify the board is running at PCIe 4.0 speeds after installing a 3rd Gen Xeon?

Check the BIOS or OS device tree — slots #5 and #6 should show Gen 4 x16, slot #3 Gen 4 x8, slot #4 Gen 4 x4, and slot #2 Gen 4 x8 via MUX when a supported processor is detected.

What comes in the box and what must I source separately for a working build?

The motherboard ships alone; you must supply one LGA 4189 3rd Gen Xeon Scalable CPU, DDR4 ECC RDIMM or LRDIMM modules (up to eight, 3200 MT/s), drives for the 14 SATA 6.0 Gb/s ports or the two M.2 22110/2280 slots and one U.2 SFF-8654 connector, plus an SSI CEB compatible chassis and power supply.

Which memory capacity should I choose — 1024 GB RDIMM or 2048 GB LRDIMM/3DS?

Choose 1024 GB RDIMM for standard density; step to 2048 GB LRDIMM or 3DS RDIMM/LRDIMM when you need the maximum 2 TB per socket and your workload benefits from the higher ranks.
