I downloaded the latest ATI tool which i have used before but it doesn't seem to work with my X1600pro. I click on find max core and the screen just goes blank or just vertical lines and i have to reboot. I read through the info and can't find any info or if i'm doing something wrong. I've this card a while and feel it's time to squeeze some extra performance out of it. Are there any other overclocking tools for radeons that would work ?
