I went from an Athlon X2 5200 2.7 GHz to a Phenom II X3 720 BE a few days ago.

I'm using a ECS A780GM-A motherboard.

The bios doesn't recognize the processor ( AMD Unknown Processor Model)

That said, this board is AM3 ready ( which means it wasn't originaly planned to be used with AM3)

Will flashing the bios to the latest one fix this ? Everything works fine, just that this annoys me a little.

This is what i bought

As long as the operating system knows what it is then it really doesn't matter. Have you checked CPU-z from windows to make sure it see it right?
