    Ok, i tested to overclock my 1 Master Card. I take the Bios, see, that the normal clocks stand at:
    625/1250/799
    I changed the Clocks in the Bios to:
    750/1250/1000
    and flash the Card with Nvflash.
    But only what happend, the 9750 boot up, the Screen flickering in Windows, and than its come a bluescreen. Maybe to much for the Card..
    than i change the Clocks to:
    650/1250/850
    Not really much, but i wanna test it. And the same! The screen was again flickering and shuts down with a Bluescreen! I overclock the Card with only 50Hz and that was to much? I installed a new driver but nothing happens, allways the same thing. Is this Card a non-overclocking Card? Some guys in the Forum overclock the card over 200Hz , but at mine nothing goes. In the Internet i read, the 8700 is a overclocked 8600. Is this the Problem? On a other Side, i read Storys, tht the G84M Chips are faulty..
    Can somebody help me? Its not importend, but i wanna know, why nothing goes with my Cards...
    PS: I think, my English is terrible, sorry that..

    I suggest overclocking in windows first, either with nvidia system tools (click on "find optimal") or with something like atitool.

    Atitool is great because it will find the max core and max memory frequency for you.
    You can sit back and watch.

    Once you find a good overclock in windows, then increase the clocks a bit and flash the vBIOS.

    Performance > device settings.

    Do you see anything useful there?

    Maybe you don't have forceware installed?
    If not, get the driver from laptopvideotogo.

    Is your power adapter connected?

    (On battery power the button doesn't show up).

    What I justed realized is that I don't have the "find optimal" button while running win7.
    I'll log into winxp and get a screenshot for you.

    But that might be your problem, are you running win7/vista?

    EDIT: Win XP screenshot:
