Once you've installed it properly, if it posts, that is, you see the BIOS, then that means it's working. Once in the BIOS, check what CPU it is recognizing to be installed. If it shows the correct CPU, congratulations, your board is compatible! If it is not pre-flashed, the computer won't do anything when the power button is pressed, that is, it won't post.
Hope this helps. Cheers!
