HD 5870, running 2d clocks in 3d apps

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?

  1. Open ATI CCC and in "Overdrive" set your core/memory clock manually
  2. It's at 890/1225

    The stock 3D speed is 850/1200 and yours are 890/1225(i think your card is factory OC'd)and the speed is correct.
    What software did you test to find that you are running @ 2D clocks in 3D apps ?

    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
  5. 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
