I just press buttons until something works and hope I don't burn something up in the process
No, really. I've been more of a trial and error type since I'm still pretty new to overclocking. Take note of what works and move on. Always keeping things within the limits of the cooling medium. I'm currently on water but will be making the move to Dice/LN2 as soon as I get all my stuff squared away.
Sorry for the hijack, back on topic.
