Single-socket AMD EPYC 8004 platform

The TYAN S8040GM4NE-2T is an ATX server motherboard built for single-socket AMD EPYC 8004 Series processors. It targets deployments that need high I/O density in a standard 12 by 9.6 inch footprint. The board fits typical rack or tower chassis without proprietary mounting requirements.

Upgrade from dual-socket or PCIe 4.0 systems

Replacing a dual-socket board with this single-socket design cuts licensing and power costs while keeping 4 PCIe 5.0 x16 slots for accelerators or networking. The jump is worth it when workloads fit within one CPU but demand the bandwidth of sixteen-lane Gen 5 links.

Eight DDR5-4800 channels and dense NVMe

Eight RDIMM slots provide eight memory channels at 4800 MT/s for bandwidth-heavy tasks. Two M.2 slots accept 22110 or 2280 drives, plus two MCIO 8x and two MCIO 4x connectors add further NVMe capacity. The 10GBase-T and 1GbE ports handle storage and management traffic without extra cards.

Questions about this item

What case clearance does the 12" x 9.6" ATX form factor require?

The board fits standard ATX chassis with at least 12 inches depth and 9.6 inches width; verify standoff pattern and I/O shield cutout before mounting.

Which CPU socket keying must align when seating an AMD EPYC 8004 series processor in the SP6 socket?

Align the SP6 socket triangle marker with the processor corner notch, lower the carrier evenly, then torque the retention screws in the prescribed cross pattern to avoid bent pins.

Which storage drives can be swapped later using the MCIO and M.2 connectors?

The two MCIO 8x and two MCIO 4x connectors support NVMe U.2/U.3 drives, while the two M.2 slots accept 2280 or 22110 NVMe modules for later capacity upgrades.
