Single-socket Genoa platform

This TYAN motherboard accepts one AMD EPYC 9004 Series processor in an SP5 socket. Eight DDR5 DIMM slots run at 4800 MHz with one module per channel or 4000 MHz with two per channel, supporting up to 2TB of ECC memory. Five PCIe 5.0 x16 slots provide high-bandwidth expansion for compute or storage accelerators.

Passive cooling and power envelope

The CEB form factor relies on chassis airflow across the CPU socket, VRM heatsinks and the Aspeed AST2600 video controller. No active fans are mounted on the board itself. Power draw scales with the installed processor and the number of populated DIMM slots and PCIe devices.

Integrated networking and storage connectors

Two 10GBase-T ports driven by an Intel X710-AT2 controller and two 1000Base-T ports from an Intel I210-AT handle data traffic, while a dedicated 1000Base-T IPMI port enables remote management. Twelve SATA ports, two MCIO 8x connectors, two MCIO 4x connectors and two M.2 slots (2280 and 22110) give flexible NVMe and SATA storage options without extra HBAs.

Questions about this item

How do I install the AMD EPYC 9004 CPU into the SP5 socket and what step is often missed?

Align the processor triangles with the SP5 socket markers, lower the carrier frame evenly, then torque the captive screws in the labelled sequence so the 8050 land pattern makes uniform contact; skipping the torque order is the common mistake.

What maintenance will the Aspeed AST2600 BMC and its dedicated 1000Base-T IPMI port need over time?

Apply BMC firmware updates from TYAN when released to patch security issues and add sensor support; the IPMI port itself requires no hardware servicing.

Which thermal limit appears first when all five PCIe 5.0 x16 slots run sustained workloads?

The CPU package power limit typically throttles before the chipset or VRM zones, because the single EPYC 9004 socket feeds every x16 lane directly.
