I want to understand what I am doing with my N9, when I'm over/under -clocking it. So I know that when I want my frequency high, there also should be some high voltage value of my core, right? And vice versa, I randomly found out. I've read that when my device gets hot (because of passing frequencies, I guess?) the electrical resistance, also rushes up, in fact, needing more voltage, because... That's where my insight is over. My question popped up, as I was experiencing a reboot at 850MhZ / 1,175V (stock?), but not at 800MhZ / 1.1V.
