the voltage was NOT the issue the overclock was. might need more voltage or you pushed to far. Trixx applies the last saved setting when its set to run on startup. It tells you its about to apply it and gives you a few seconds to cancel it and keep it at stock settings
So if I were to start up Trixx right now, it would go to stock settings? I think you are right because when this Overclock failed, I had just clicked apply at the bottom, but never confirmed anything after that because the screen was black.
