    So, i cannot go up than 4.2, 4.1 4.1 4.1 and + 77mv offset voltage core. my cpu suck 58,3W maximum so, if i understand, the rest of my laptop would suck 81,7W ?

    my DVD drive, dedicated graphic card, bluetoooth are disabled, i can unplug then to save some W but not sure it it's work, well my overclock is engought now, no need more but i think it's possible :) share your work dude this tips able you to make a gamer pc for low $ just with a good overclocking.

    EDIT :
    I've found a way to enable the powerCut, just click on the checkbox to enable it, quit FIVR and re-open it, set your processor offset voltage to a low value to make a crash, let your laptop restart, reopen throttlestop and you're done ! You can now overpass your tdp limit, i'm currently running @4.2Ghz, just amazing !

    Note : I've added a fan on my MSI GP70 2PE, the temp drop a lot :D it's noisy but i prefer perfs ;)

    http://www.majorgeeks.com/mg/getmirror/uefi_bios_updater,1.html

    download UBU tool, extract on a folder, download your original bios from your constructor website, extract your bios in the UBU tool folder, run UBU.bat, press 7 (update microcode), press 1 , 1 again, after it's done just press 0 (exit) and 1 (mod_XX_BIOS_XX.XXX), rename this bios in a simple name like b.XXX (XXX is the file extension of your bios), download rufus here : https://rufus.akeo.ie/downloads/ (last version), run it, plug an usb key, format it (file system EXFAT/FAT16/FAT32, operating system MSDOS), download AFUDOS here https://ami.com/en/download-license...IOS_and_Aptio_AMI_Firmware_Update_Utility.zip, extract all file on your usb key WITH YOUR BIOS MODDED FILE !

    Reboot your laptop on your usb key, and type AFUDOS b.XXX /GAN

    replace b.XXX by your moded bios file name

    /!\ Be carefull, the size of your new modded bios must match with the old ! the program check it for you.

    Cross finger ... and after 3 auto reboot, you're done ! Your microcode is downgraded !

    Note : You can use AMIBCP4.53 (google it) to unlock some feature of your bios like cpu configuration and much more !

    Enjoy your unlocked laptop ;)

    Is this same microcode bug exploit usable on a Kaby Lake i7 7700HQ too? I thought it was very closely related to the 6700HQ.

    Hi
    It was mentioned in firs post that this mod was tested on desktop i5 as well. Does anyone know on what kind of desktop chipset this mod work. Is it only on Z87/Z97 or on non-Z to?

    I'm with MiSJAH on this one. It'd be super cool if you could make your guide a bit more detailed. I know how to overclock, but I'm not at all familiar with the hex editing.
    It's super interesting and I'm curious to see the process behind it.
    It would also make me feel a lot safer about trying it.
    The 4720hq is realy getting on my nerves so it'd be cool to get a bit more performance out of it right after my fresh repaste :)
