    Hey team!

    Just came by to say that the bios is 100% working.

    Few notes that you should be aware beside what overclocking guide presented:

    Put the mem speed in auto, otherwise i couldnt raise the v-core by more than 1.200v

    If Pc crash and you are stuck with the stock settings, just clear cmos ( Take the motherboard battery off).

    Best Regards and good Overclock

    Doesnt work for me
    i have 6600
    i also can set the CPU Core Voltage to 1.325 without problem
    but i can’t find CPU Loadline Calibration Mode 1 in the bios

    when i’d raised BCLK to 1 it doesnt started.

    Not working on msi z170a pc mate. I used the correct bios, but think it’s for 170 board and not 170a. Won’t let you raise the BCLK at all.

    Do not start the system.
    1) to save the configuration
    2) restart after 5 seconds, and then restart
    3) The settings are not saved. frequency 3.2

  • Can anyone let me know if the CMOS reset on this board is faulty? I updated to this bios to allow BCLK overclocking and after I put 137 BCLK and raised the V to 1.325 the board went into a dead state. I do remember that I forgot to select the loadline calibration and restarted with those settings. The board went dead and attempted a lot of times to reset the CMOS bios to default settings and it does not want to reset. The Bios updated fine and booted with its stock settings.

    I removed battery then initiated the CMOS reset and nothing happened. The Motherboard does not detect the CPU any more and has the CPU LED light lit up.

    Also the BIOS UI was very slow when switching between pages and settings. Did anyone else experience the same?

    Does anyone know why might the CMOS reset does not work? Is it possible the Bios is not the appropriate bios for the Z170 PC Mate?

    Do I have to RMA the board again after the first board attempt failed and had same results?

    Thanks for anyone that can help.

    Overclocking with this Motherboard is pretty complicated and you probably can’t go more than 4.55GHz.

    I’m very dissapointed :c

    p.s. – if system fail to load once you have to remove battery every time, otherwise you will stuck with stock settings.

    Hey guys, so i am having a bit on an issue on the BIOS. I managed to oc successfully an i3-6100 with the Z170a PC Mat to 4.4ghz, but i decided to check if it can oc to 4.5ghz but it failed. I can’t go back to my 4.4ghz settings, i tried doing cmos reset and doing the same steps again and nothing. I am wondering if any of you have an I3-6100 and the same motherboard as i and has had success oc and is dedicated and patient enough to help me with this. I am not a oc computer pro so maybe i am doing something wrong. I also have the Bios update provided by you guys. Please let me know if any of you can help, it will be greatly appreciated.
