    True, so if this works would it be harmfull to the GPU?

    The GPU no, but it will put the power circuitry under more stress.

    I succesfully flashed the bios to the Asus version and made my own curve in Afterburner.
    The PL is raised to 90w in benchmarks there is no big difference FS is around 17600 graphics score which is 3,5% faster.
    In-game though you get 5-10% more FPS compared to the 80w undervolt bios.
    Clockspeeds are between 1590-1650mhz and the max. temperature is 79 degrees with the same fanspeed (45%).
    Did a few hours of stresstesting and gaming and everything is stable.

    Temperature on the gpu/vram looks good and a nice improvement on the FS score.

    Keep an eye on vrm temps when doing such mods. Having all the mosfets and chokes cooled properly. And check that they have proper contact between thermalpads and heatsink.

    The chips should leave an impression on the pad.

    IIRC the chokes dont really need cooling. Most are rated for operating temps of up to 150C and only see a delta of about 40C at their rated current load.

    The mosfets, especially in a laptop form factor should be cooled, however they really dont need much cooling. They typically dissipate only a few watts at their rated loads and that's usually within or close to their package specifications.

    I would say it's more important to ensure you're not driving them beyond their rating when asking for more current. Typically they're way over specced, but it's good to double check. You'll probably run into stability issues with dirty power before you run into issues due to over driving a mosfet when you start asking for more current. Laptops have fewer phases than desktops typically.

    Rated loads is one thing but if you are increasing TDPs you can rapidly go from 2.5w to 5w.

    Small update:

    Yesterday I optimized the profile and installed modded Nvidia drivers from this thread:

    http://forum.notebookreview.com/threads/modded-nvidia-drivers-for-windows.826322/page-37

    Now I have a graphics score of 18.024 and everything is stable in-game:

    It's nuts when you compare it to the out-of-the-box performance:

    https://www.3dmark.com/fs/19426224

    With the tweaking mentioned in this thread I got these performance gains:

    FS score: +20,8%
    Graphics: +14,12%
    Physics: +28,11%
    Combined: +38,52%

    It's a decent gain but still a lot less than it used to be, back in the 680M days you could get an extra 50% graphics performance lol.

    50%?! Woah

    There were a lot of fun ways to grab extra performance, hard mods, cross bios flash etc. I remember unlocking extra pipelines on my 6800nu agp card on my pentium 4 machine and rocking that 3dmark 03 score.
