Support for BCLK Overclocking of CPUs like i3-6100, Pentium G4400, i5-6400, i7-6700 and all other non-K CPUs.

Don’t use this for K-series CPUs.
It might damage your hardware, no guarantees provided.

Issues found so far

  • No IGPU
  • No dynamic change of CPU frequency
  • No C-states
  • No Turbo Mode
  • CPU temperature reading is incorrect
  • AVX instructions have very low performance
  • Windows XP ACPI not supported

After flashing set the following settings to make it boot into OS with correct CPU speed

AdvancedCPU Configuration

    Tried updated to this BIOS, but there’s problem:
    There is no such option:
    AdvancedCPU Configuration
    – Boot Performance Mode -> Turbo Performance

    Every overclock will fail at boot.
    Can you help me?

      Try these settings (for Pentium G4500), they worked for me. Thank me later:
      In BIOS, go to Advanced Mode → Ai Tweaker
      * Ai Overclock Tuner = ‘XMP’, ‘No’
      * Asus MultiCore Enhancement = Disable
      * CPU Core Ratio = ‘Sync All Cores’
      * 1-Core Ratio Limit = ’35’ by default
      * BCLK Frequency = ‘120.00’ (35 x 120.00 = 4200MHz).
      * Make sure DRAM Frequency = what your RAM supports
      * Go to DIGI+ VRM, CPU Load-line Calibration = Level 7.
      * CPU Core/Cache Voltage = ‘Manual Mode’.
      * – CPU Core Voltage Override = ‘1.300’ (That’s around 0.15 above my stock voltage).
      * Leave the rest of the settings at default
      * Go to Advanced → CPU Configuration → CPU Power Management Configuration, disable Intel(R) SpeedStep(tm) and CPU C States.
      * Save your settings and boot into Windows.

        Thanks for the great feedback 🙂

        Your method is not working for me.
        I have:
        – Z170m-plus with 8001 bios,
        – i3-6100
        – Kingston Hyperx DDR4-2400 8GB

        Following your steps, even if I set BCLK to 101, it won’t boot past the POST screen. I can’t even see windows booting…
        I tried lowering ram frequency to ~16XX, didn’t work.

        Anyone can help plz?

        • saowei.liu

          Did you succeed?i want to buy Z170m-PLUS to “OC” my 6400t, but i cant insure it work or not。

      • Franck

        Successfully overclocked i5 6400T with stock cooler following your advices. Now tweaking it up to have a optimal overclock with low thermals.
        BTW, I’ve deactived turbo boost (while it’s not stated anywhere here), is it safe to enable it? What will I gain doing so?

    Will this BIOS work on a Z170M-PLUS/BR? This one:

    Looks identical to the Z170M-PLUS.

  • Jay Scott

    I have an Asus Z170M-Plus currently with 1803 Bios and was unable to flash to the non-K 8001 OC Bios.

    “Selected file is not a proper BIOS” was the error displayed.

  • JumpJet

    Please I need help too. I cant flash the Bios to 8001 as needed.

  • Thanks for the 8001 file. when i heard that the companies locked the mobo bios. i thought that i had lost this for good.

    Someone with skills needs to fix it though.

    • Mgik

      You mean fix the bugs?

      The stability of this BIOS is disappointing.

      Sometimes it will suddenly say over clocking failed at boot even without oc
