I can't seem to find the way to oc my 4870x2 for 3d apps only(returns to normal clocks in 2d apps). In past RT versions I know you could simply select "performance 3d" from a dropdown(top right corner) on the oc page. I've read all of the guides my Google search could find but, it seems this aspect is newer than any guides cover. I want to continue using RT because I finally figured out how to shut down my system on a temp. threshold event. If it's in the documentation, I can't find it. :bang: Teach Me Please, that I might not wallow endlessly in my ignorance!
