I am providing the following BIOS screens with comment in the hopes that this will answer some of the more frequent questions we get here at XS concerning how to unlock the full potential of the Asus P5B Deluxe motherboard.
Not every board is the same, not ever CPU/memory combination responds in the same manner. This guide is not intended as a 'Set-it-and-Forget-it' solution. As with all overclocking, user participation and thought is still required.
