    I am new to using this amdgpuclocktool. I followed the instructions and it worked. My question now is do I have to do this everytime I start windows or is there a way to automate it? Also do you need to disable any ATI services?

    UPDATE: I thought everything was working because when I bumped each one up a little it worked. When I used the ccc overdrive it found a core max of 866 and memory max of 748. When I used amdgpuclock tool, the highest I could get the 2 cores was 850. Anything higher and when I click set clocks I get the message box that says SetClock Failed! Please check device configuration. Any ideas what I am going wrong here?

    Okay I don't know that is going on here but this is the scoop. If I use Riva and oc the card in riva, it sets the oc from gpu2. If use amdgpuclock tool it sets the oc from gpu1. I cannot get both gpu's to oc from amdgputool. Any ideas how to help me out with this one? Also I have to do each time I boot up.

    any idea about the temperature of the card in over clocking?

    I try to rise the gpu clock from driver(catalist), but at 865mhz the screen go white :) so I belive the limit is around 850-860 from the driver

    CY:G man 105 Celsius?

    I think that the fan dont rise the % with rising temperature, some how the power play don't work for your card

    my card at the default clocks in desktop stay in 42-48 degree and in full load go to 76-82

    Well I've been at this for over a week and I can't seem to get my second core to kick in. I get 10k scores for 3DMark06 and crappy FPS in most games.

    I tried doing this fix and still only 1 GPU shows up.

    Do I have to use RT v2.06? All I can find is RT v2.08.

    Does RT need to be running for the AMD GPU Clock Tool to work?

    I have gotten the CPU to 3.75GHz(E8400 - 9 x 417) and my video card to 950/1950 and 3DMark06 score of 11.5k. I know it should be well over 15k if not close to 20k.

    Am I overlooking something?

    ps. I have a Sapphire HD3870X2 and it doesn't seem to be a reference card.
