7. If you reboot, the overclock is reset back to default. So you will need to re-enable the overclock. (this is the safest way to avoid a constant reboot upon applying a unstable overclock although titan's kernel now has protection against this ever happening) I recommend you use the Queen Beecon Widget method I mentioned below on this guide. according to jakiman. but i do reboot on stock or a custom setting in some reasons.
