My guess is that the Asus software changed the cards BIOS so it was overvolted. That wouldn't change because of uninstalling the software. If you want to change the cards voltage back to stock, you would probably have to re-install the Asus software again.
that's so weird! actually i'm fine with it overvolted, and i prefer to use CCC as it runs in the background anyway. no reason to have multiple softwares that do the same thing.
one weird thing though is that my GPU fan goes to 50% from the moment windows starts until CCC starts running, and i have no idea why. is that bad for the GPU and/or any way to fix it?
lastly, the power slider i have at 10% in CCC--should i switch that back to 0?
