Hi, I have a XpertVision (Palit) X1600Pro Golden edition. When I try to use "find max core/mem" the result is that Ati tool raises clock rate so far that the card/program crashes. So it doesnt find any Artifacts and it gets on and on rising the clock rate before crash. Crash happens about at 680Mhz core and 750Mhz memory (Default is 573/648). I have tried 0.25 Beta 14 and 0.24 with windows XP and XP 64, same problem in all. Any ideas? Thanks for help.
