    How do I make my video card start in underclocked modus?

    I have an old 8800M GTX that has been failing for about one year now.

    Running at normal clock speed, the card bluescreens the computer right after windows has started.

    I have to run the card at 1/3 the clockspeed (about 200mhz core / 400mhz memory) in order to avoid crash.

    So is there any way to make the card run at that given speed on boot?

    Hm, how do I do that?

    So far I've been using the nVidia control panel to control the clock speeds, but since nVidia makes such crappy drivers it crashes 90% of the time so it's a very long process. (yes, it also crashed even when the card was working 100%)

    Restart in safemode, use GPU-Z to extract your vBIOS, set the clocks you need (and think about undervolting) with NiBiTor, check checksum and flash it using nvFlash (-5/-6). Make sure you backup your vBIOS with nvFlash prior flashing the new one.

    Already tried to 'bake' your 8800M GTX?

    Yes, I shall attempt the baking process soon enough, but I'm needing some parts from Kobalt which hasn't been shipped yet, and I cant get in touch with any of them so I donno what to do.
