    M11X R1 Voltage Keeps Dropping

    I've already flashed the increased voltage BIOS, letting me hit .95, which is pretty sweet, but I first noticed when playing Assassin's Creed: Brotherhood that my voltage was dropping after some game play. When I first ran it, I got a good 2-3 hours, then suddenly my FPS were decreased substantially. Still playable, but just barely, as opposed to the fluid gameplay i was getting beforehand. The second time I ran it, i got a good 30 minutes, then BAM, less than impressive frame rates. I eventually deduced this to my voltage dropping.

    Checking GPU-Z, when this happens, my max voltage is .85, and it never goes higher, not even to .90. The only method that seems to work to raise my voltage again is to just restart my laptop, but even then, I've had a couple of occurrences where my voltage will just refuse to increase without any gaming beforehand.

    The only other thing that can induce this is by stress testing my GPU.

    Bottom line, any way I can avoid this?, get around it?, and does it mean my GPU is on it's last legs?

    I'm getting ready to do the pinmod to hopefully reach 2.4Ghz, or at least 2, so would this help, or make this impossible.

    I have mine running on the stock BIOS without OV'ing the GPU. The 335M has 3 P-states. High power, medium and low power. The voltages are 0.9V, 0.85V, and 0.8V respectively on mine.

    Try playing with the power plan on High performance. I am not too sure if updating the drivers will help or not.

    Yup, I didn't know that the power plans limited voltage. But again, when running on the highest plan setting, gaming after a while causes the voltage to be forcibly lowered, and switching plans doesn't even let me reach .9
    Any solutions besides restarting, and hopefully a permanent solution to prevent the voltage from ever dropping?
