am not into computer so much, so excuse me, you overclocked it to 1200Mhz with 62c ? what is fan profile ?
Mine is 1135 / 1625. vCore 1.3 vMem 1.625
I think I can push the memory a bit further but so far this is the most stable setting I have. running heaven benchmark several times with ultra setting with no prob. the card got a little hot, 75ish at max load.
