If a motherboard can run a 64-bit processor, it is a 64-bit motherboard.

All of Intel and AMD's motherboards that have the correct socket type for a 64-bit processor can operate in 64-bit mode. The socket is the part of the motherboard that connects to the processor. The motherboard may need a BIOS update to run a 64-bit processor when upgrading from a 32-bit one. If you are wondering if a motherboard you are running is 64-bit compatible it may be faster to first check if the processor you are running is 64-bit compatible. If the processor is not, you can check the motherboard's socket type.
