I was trying to get the fan speed profile to work (auto control) based on temps. Even though it was set in the .over file the -b flag would not engage it. I did not try a static fan speed setting.
Yes, that is the only option that does not work. It only works with the GUI on, dont know why. I have opened a bug, maybe you can add a comment so it picks the attention of the developer:
http://sourceforge.net/tracker/?func=detail&aid=3322352&group_id=387278&atid=1609264But aticonfig does not allow this option neither (as far as I know).
Another thing, I have one card that doesn't like being clocked at 1000 so I set a .over profile at 950, it would spit out that it was seting the clock at 950, followed by output stating it was set back to 1000. Maybe I am doing something g wrong but I could not get different clock profiles to run concurrently on different cards.
Are you setting it in the right performance level? Also, you can not set a gpu speed lower than the previous performance level. F.e. if performance level 1 has gpu speed at 975Mhz, you can not set pu in performance level 2 a gpu speed of 950Mhz. To have a pgu speed of 950Mhz on performance level 2, set the gpu speed in performance level 1 under 950Mhz.
In general you should not have a higher setting for anything, gpu spped, memory speed or voltage, in a lower performance level.
One more thing, it does not affect mining apparently, but it is also recommended that the memory speed is the same in all performance level, specially in the card connected to the screen (if any).
