    As Title says.

    I am experiencing some problems with my brand spanking new M17X R3.

    There's a Radeon HD 6870M in it and I know it is very overclockable.

    The problem is, when I install MSI Afterburner to move the clock sliders and I successfully apply the new clocks (which, on my card, fortunately go to top settings without a scratch - 860MHz / 1200MHz GPU/MEM), I see the screen "rattling" up and down, some times.

    Being more specific, I see my desktop scrolling up-down of 1-2 pixels (sometimes), and this only after the overclock.

    Any idea? Maybe more voltage is needed, but I have no idea on how to tweak Afterburner to enable the voltage slider...

    NO GRAPHIC ARTIFACTS I must say. Only this annoying "scrolling".

    what happens if you lower the clocks slightly? Do you still have issues?

    BTW, MSI Afterburner is great with nvidia cards. I don't know if it has any detrimental affects on AMD cards (i don't think so, but i'm not sure)

    most AMD users use Sapphire Trixx:

    If I lower the clocks a bit (760/1050), the thing stops. So I was thinking to some SW problem, since the HW is fine and stable, there are no artifacts and the Radeon HD 6870M is based on the Desktop HD 6770, that run base clocks of 850 - 1050...I will try with TRIxx!

    And please, reply also here

    also what are your temps at 860/1200?

    Seeing how things are ok when you lower the overclock, i'm inclinded to think that you are going too high for your card to handle. You probably need more juice to keep the card running at 860/1200..but that means you'll need to do a voltage mod. becareful if you even try it cause you can brick your card

    61C after 3DMArk 2006, less than 50C in idle

    So there's no overvolt option in trixx? I thought I could do it SW easy...I'll see what I can do.

    ty for assistance!
