Hey, yesterday i received my sapphire 7850 i decided to have a look online at people using the amd overdrive and most said they could run it on full settings so i tried it out. changed gpu clock from 860 to 1050 and high performance memory setting from 1200 to 1450. as soon as i launched bioshock the screen started flickering and blurred, multiple restarts wouldnt solve this i had to go through safe mode and set to defaults. through all this my temp stayed at about 28 degrees Celsius. i was just wondering what would cause this and if i am to over clock it what would be a suggestible amount .
thanks
