Hello I was using ATI tool 0.25 Beta 14 yesterday to OC my card. I was using this guide: http://www.madshrimps.be/?action=gethowto&howtoID=61 After testing for some 10min my computer locked itself and I had to restart. After Restart there where actifacs on the screen in the BIOS screen and Windows startup screen. And when I entered windows the artifacts disapperd, but the computer locked itself agian when I starded a 3d-application. After several restarts the card got totaly unstable and I had to give in. I looks as if the card is destroyed! I have OC the card in CCC and have had no problemes there. I use a zalman cu-900 cooler on the card. The GPU temp was on 92 degrees when the computer froze. Any one got some thoughts on this?
