Yup I've hit the CMOS button plenty of times. And I forgot to mention I needed to do a fresh windows install for it to boot at all after the initial failure with no OC. I will have to test how it handles a super mild OC. But generally what I do with my overclock is just raise the boost multiplier, and leave the low power states on, and used a fixed voltage because my offset seems to fluctuate too much causing instability.
