I have been working around with this card for a while and trying to find a good overclock and when I go above 1490 MHz It starts to crash after a short while. Knowing this I set it to 1480 but sometimes(a little more often lately) its starts to crash. I want to get it to 1500 or a little higher but I cant so I'm wondering how to go past the max 120% power target because ive seen people go to 125.
