i was really impressed with this program, until i tried to save the mem/core clock speeds and it caused the PC to lock up, as it applied the speed, but not the fan, and then not the voltage, etc. and then only to one card. it might have been an older version but it was annoying at the time.
What a version of program did you use? Some remarks about 1.77 release: when you push on Clock Speed you can manage the autostart of Core, Memory and voltage only. You must push Fan Speed button to manage the autostart of fanspeed. There must be a fanspeed value in the appropriate section of Clocks.ini after that. If you have 2 or more videocards the clock speed and fan speed buttons must be pushed in each tab corresponding to your adapter.
it also makes sure to return clock/fan/voltage rates back to normal when you close the window or quit cgminer, which can be a help when you need to shut down, be in the same room as 4 GPU fans at 70-80%, or play games for a few hours and return to mining, etc.
the feature to return clock/fan/voltage rates to default on exit may be realized in the future versions.
