    Hey guys!

    This is my first BIOS mod so it took a while to figure out, but I've created an unlocked BIOS for the Gigabyte P34G.

    I have tested this personally, and it seems to work fine, but the usual disclaimer applies. I am NOT responsible for any broken machines.

    Turns out Gigabyte actually included a convenient "Hidden Function" switch (under Advanced), which, when set from ENABLED to DISABLED, unlocks a bunch of extra BIOS features, including:

    Adjustable TDP in Intel XTU (disable Platform Power Limit Lock and Package Power Limit Lock in Advanced > CPU Configuration)
    Variable Number of Cores
    Disable Hyperthreading
    And a lot more I haven't gotten a chance to explore yet!

    Here's an album of all the unlocked menus: http://imgur.com/a/sHsRH

    To flash, simply download and unzip the package, and run FLASH.bat.
    Note that this
    Please report back with any findings. Happy Exploring!

    Hello,

    Thanks a lot for this mod, much needed one...does this help to avoid the fan ramp up at 50 degree temp and control the fan in more optimal manner. Also can we go back to default bios by re-flashing to stock one once changed to the modded one.

    Please let me know. And thanks a lot for your help.

    In one of the images there are fan options. It seems you can select the fanspeed and the fan turn on treshold. Would be nice if someone could test this.

    Hasn't been working for me, but someone else might be able to figure it out.

    Yes, you can go back to the original with a simple reflash.

    Would suck of one of these unlocked options is broken and bricks the device though. Testing needed

    I know I replied in the owners thread - but thanks a lot for finding this tocirahl :).

    Here's hoping we can use it to get the Notebook Fan Control to work and extend the battery life of the device :).

    Were you able to use any of these functions to modify the functioning of the computer successfully?

    Thanks,

    I've definitely been able to modify things like number of cores, unlocking things in xtu, turning off hyper threading etc.
