I'm using a Radeon 9550 video card (stock frequencies: 475/325) and Catalyst 6.3 drivers 1) While I can see the visual artifacts while doing a "Find max..." procedure, ATI Tools doesn't detect any artifacts. 2) ATI Tools loads the startup profile every time I load it. This is not really a bug, but I don't understand the purpose of being the way it is. More useful would be to load the startup profile when the OS loads ATI Tool at startup, with the "-s" switch. For example, if I make a change to the frequencies and close the program, loading it again resets the clock frequencies with those of the startup profile. As things are right now, I don't see what purpose the "-s" switch does it serves. 3) This is a feature request: I don't know how ATI Tool sets the frequencies, but I think it would be nice if you could set a time interval (from ms to several seconds) and an increment/decrement value (in MHz) so when downclocking/overclocking, the program decrements/increments the clock, at every time interval, with the selected inc/dec value, until the selected clock frequencies are reached. This would be done to protect the video chip/video memory from damage.
