    Hi, I have an msi gt73evr with hm175 and 1070/7700hq.
    I have unlocked my Bios with help from Svet on msi forums!
    I try some OC but there is too many ways to be blocked :(
    What settings do you want to test? For?

    Hello.
    In your bios, change the following settings:
    C states: DISABLED
    Power and performance ->CPU power management control->CPU VR Settings->Core I/A Domain:

    Make the following changes:
    IA AC Loadline ---> 1
    IA DC Loadline----> 1

    CPU VR Current Limit --> 600
    IMON SLOPE--> 50
    IMON OFFSET --> - 31999 (negative, NOT positive)
    Change the + sign to - (change the positive to negative) above imon offset.

    Make sure TDC is set to disabled and "0" below that.

    Save and exit.

    When you are back in windows, download prime95 from
    https://www.mersenne.org/download/

    Also download Throttlestop 8.60 from https://www.techpowerup.com/download/techpowerup-throttlestop/
    Run it and have "LIMIT REASONS" or "LIMIT" button opened.

    unzip it, run it and chose "Torture Test-->SMALL FFT".
    *MAKE SURE YOU ARE USING COOLER BOOST 100% button (press the button on your laptop below your "GPU" button for max fan speed.

    While running, look for Power Limit 1/ Power Limit 2 throttling flashing in red. Or PL1 or PL2 (same thing).

    Please report back.
    Your CPU should be at 3400 mhz at all times without dropping down lower, during this test.

    I already told you.
    But if it was confusing to you, to see if you get Power Limit Throttling at heavy CPU load. The 7700HQ CPU is supposed to power throttle at 45 watts of TDP (power draw rating).

    I said this clearly in the last message.

    The settings I changed will make the CPU report it is using "less" power than it actually is using (the IMON Slope=50 and Imon offset= negative 31999 will make that happen).

    I don't know if it can help, but few days ago I try to "OC" my CPU, and when adjust a voltage ( not core but something else ) I can "use" more than 45W. I reach 60 and more reported by CPUIDHWmonitor.

    I will try your settings and see what happen

    Few days ago too I used throttlestop to make my CPU works at 3.8Mz ( turbo mode ) on all cores
    My temps are getting higher, Watts consumption too, but on benchmarks, there seems to be no difference... Do you know why?

    Excuse me, when I understood everything right, there's no way to unlock the CPU-Multiplers? Until someone could modify the microcode in EC-Firmware without trouble about the hash?
    That causes theres now way to overclock on the Multipler-Way?

    &
    That's good to know! But someone have a link for MSI Silent Option for Kaby Lake?
    Also a link for latest version of MSI SCM Hotkey would be greate.

    Thanks in advance

    Skylake version of Silent Option works on Kaby and Coffee. Google it.
    Overriding CPU multipliers on HQ processors cannot be done. It's hardwired into the CPU itself.
