My 5870 refuses to run in 3d clocks which causes unbearable stuttering in Guitar Hero 3. Is there any way I can force it to run in 3d clocks while I'm playing the game and then throttle back when I'm finished playing?

Open ATI CCC and in "Overdrive" set your core/memory clock manually
I OC'd it myself, and I used MSI afterburner played a 5 minute song and then checked what it was doing. It was running at 157/300
Well in 2D apps it runs @ 157/300 and playing a song is actually in 2D mode. So run a game and test with it. BTW although MSI Afterburner is a good tool but it has some problems,so check your speed with GPU-Z/ATI CCC
