Know before you buy
This motherboard is specifically designed for AMD Ryzen Threadripper PRO processors using the sTR5 socket. It is not compatible with standard consumer-grade Ryzen or Threadripper CPUs.
Yes, because it uses the SSI EEB form factor, you will need a large workstation or server-grade chassis that supports this specific extended ATX footprint. Ensure your case has sufficient mounting holes and internal clearance before purchasing.
While the board supports ECC memory for mission-critical data integrity, it is also compatible with standard DDR5 modules. For professional workstation stability, however, ECC memory is highly recommended.
The board features 7 PCIe 5.0 x16 slots, providing massive flexibility for multi-GPU setups, high-speed networking cards, or specialized storage controllers. This makes it an excellent choice for heavy rendering or AI development workloads.
The board includes an integrated ASPEED AST2600 graphics chip, which is intended for basic display output and remote management. For any professional creative tasks, 3D rendering, or gaming, you will need to install a dedicated graphics card.
The dual 10GbE ports allow for ultra-fast data transfers across your local network and provide redundancy for critical workstation tasks. This is particularly useful if you are working with large media files stored on a network-attached storage (NAS) system.
