    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 :)

    Hey dude, if you are not affraid by 1.3V + Vcore, you can try to disable VR Fault, if you have a big power brick you can go highter.

    I've reached stable 4.6Ghz (1.42V) , put some fan with tape on the air extraction of your laptop, use liquid metal + copper heatskin are you're done !

    I can get near of an i7-7700K for free, i5 8XXX if i disable multithreading -> Up to 4.7Ghz. (on 4 cores)

    I've not pushed away , i've hit my powerbrick limit (if your laptop submit shutdown, not engought watt)

    If you are too unstable try static voltage !

    About me : (HT enabled, ratio on all core, no turbo boost)
    41 : +91Mv
    42 : 125Mv
    43 : 183Mv
    44 : 250mv unstable -> 1.28v static -> stable
    45 : 1.35v static
    46 : 1.43v static

    I'll not try to go highter cause electron migration, i can keep my cpu cool with lot of fan added (i've maked hole, plug fan, and the temps drastically down)

    About 450-470 Mono thread / 2400-2500 Multi thread on CPU-Z

    this 4720Hq is not bad, what your scores ?
