    Somebody use this bios to overclock a non-k processor?

    I try it, but don’t work.

    I try with F6 bios (my motherboard comes with it), but not work.

      Hello there my features of bclk overclocking are locked even after upgrading the bios from f6 to f5g.

      Do you know how to unlock them and how can i overclock my pc?

      • Citizen3rased

        I have the same issue. I was able to successfully flash the F5g Bios, but the features to OC are still locked. Anyone figure out how to unlock it?

  • Hi, working in Z170X-Gaming 3 rev 1.1 or only 1.0?


    • kite

      mine is rev 1.0, the bios Version 5g works, my cpu is the I5 6600, I can OC. I don’t know about the rev 1.1 if it works or not…

    I thought I would share my experience with this motherboard.
    I have the rev 1.1 motherboard and I was able to downgrade from the F7 bios that it came with to the 5g bios that I downloaded here.

    I was concerned that it wouldn’t work because of a few small differences between the V1.0 motherboard, and the v1.1 motherboard, but it worked on the first try!

    I had to create a bootable usb flash drive, which I used rufus to do.

    then I download and copied the contents of this archive :
    to the flash drive.

    the last step is to extract the bios that you downloaded from here, rename it to bios.bin, and copy it to the flash drive as well.

    next, reboot your pc and make sure its setup to boot from the flash drive. it will automagically re-flash your bios with the f5g bios and you can follow the rest of the steps in this guide!

    this will let you downgrade from the later f21 bios apperantly.

    Okay so from experience you have to have a bios on your mobo that is older than the one given above.
