I have a new sapphire hd4830 that i keep getting BSODs everytime i try to use CCC or tray tools to oc the card. i get the BSOD when i use CCC's Overdrive 'auto-tune' utility or ATI TRay Tool's 'Hardware' overclocking page to auto-find max oc values.:bang: i've done a clean install of the catalyst suit/tray tools after removing the tray tools and ati drivers,software,etc/ using driver sweeper/ CCleaner's reg cleaner. i'm running winXP home sp3-updated this week from MS website, intel C2D E5200, gigabyte EP43-DS3L mobo, 3gig ram. my gigabyte/sapphire drivers are latest release as of this week. (no beta)
Are you just trying auto tune then it crashes after awhile? Or is it as soon as any change is made that it BSOD's?
