    I used to think my GPU would downclock because it overheated... but the last two times my GPU downclocked it was at 67 degrees C while playing Mass Effect 2... this happens also with other games. It will freeze and i'll hear popping noises, sometimes i can get out of the game, sometimes it completely freezes. I did some research and I think its DPC spikes causing the GPU to downclock... I have a GeForce 9500m GS running Duo Core 2.2Ghz Win 7... Does anyone know any fixes for this? It's getting really really annoying. I do have the latest Verde Driver from nVidia...

    vKrazy, you've got a 6920G right? Have you tried ThrottleStop, the one-size-fits-all fix for CPU throttling yet?
    Give the Definitive Guide a spec.

    Yea Throttlestop (thank god) fixed the CPU from downclocking to 50% and then would cause the GPU to downclock. That whole problem is fixed. Yet still my GPU will downclock seemingly randomly when i'm playing a game. It will stutter, the screen will usually freeze, i'll hear pops in the sound. And if I can alt tab I see that my GPU downclocked even though my temps were really low like I said. And yes I have a 6920g.

    I'm gonna try and cause the problem to happen again, and i'll save a picture of msi afterburner and throttle stop, see if that can help.

    Well after about 30 minutes of playing it froze again.... but my comp also froze. Do you have any ideas? Could it possible be because I have overclocked and its just unstable? But other games like Dragon Age don't do it.... ugh....

    That could certainly be it.
    Go back to stock clocks and see if that fixes things.

    Apparently Mass Effect 2 has a lot of bugs in general, however Borderlands froze for me last night twice, so I'm gonna put my OC back to default (was OC'd to 675/1350/520)

    675/1350/520?! Holy snotboogers, that's a ridiculous OC.
    Are you sure your memory chips weren't turning back into silicon there?

    I had the same issue I solved. the way I solved it is by forcing the performance level in rivatuner to performance 3d, as i dont want to resort to stock clocks. here's what i do:

    in power user

    RivaTuner\Overclocking\Global
    Set DisableClockTest to '1' and MaxClockLimit to '100'

    Rivatuner\NVIDIA\Overclocking
    Set "EnablePerfLevelForcing" to 1 and EnableLowPower3D Control to 1
    DisableMemClkResetProtectionWarning to 1 like the others you set to 1

    Finally, go to the Main tab, under the driver settings, click the half arrow next to "customize", click on "system settings", go to the overclocking tab, enable driver level overclocking, set it to performance 3D and set your GPU clocks (mine = 625/1425/475). Towards the bottom, you will see, "force constant performance level", set that to performance 3D as well and click apply.
