Basically the subject sais it all but ok I will write some more details about my question. I love the tool PhenomMsrTweaker, because it changes the clockrate and corevoltage of my cpu differently in different P-states, just as I like. Is there something like this for GPUs? Of course I could flash my BIOS for changing different p-state settings but somehow I dont like to do that to my graphics card if it is not fully needed. And then at first I have to find the optimum settings for the idle and full-load moments as well. This means over- and underclocking as a service would be nice, especially when there is a tool that just plain does that. Thank you for any serious and helpful hints or advices. PS: Please don't hate me for not spending hours searching the board.
