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

    in Advanced CPU Configuration no Boot Performance Mode is why you can not set this parameter, the other parameter set but unfortunately my i5 6600 does not start overclocked, the computer restarts and the BIOS returns to the default settings. Anyone have any ideas or manual how it all set up,

  • Kaudii

    ok my mistake, but modification works in AIDA64 shows me that the CPU runs at 4400 MHz and it is ok, but my question is it possible that my memory worked at a speed of 3200 MHz nominal or nietety only 2660 MHz. I will be grateful for your response.

    Greetings. To 4.38ghz it is what works for me at the moment as it passes performance tests.

    With bios vertion is 0602
    Set the parameters in the Bios

    Advanced
    – Boot Performance Mode to Turbo Performance – do not have it !
    Advanced / CPU Configuration / CPU Power Management Configuration
    – Set Intel(R) SpeedStep(tm) to Disabled -> ok
    – Set CPU C states to Disabled -> ok
    Ai Tweaker / External Digi+ Power Control
    – CPU Loadline Calibration to Level 7 -> ok

    – BCLK Frequency 125 Mhz
    – DRAM Frequency at about 2666 MHz
    – CPU Core Voltage Override to 1.425

    Nothing bad, but I would like to take at least 4.8GHz.

    Thank you for your guidance to take it to 4.8GHz

    I cannot update to this bios… The Error i get in windows or EZFlash in bios is either Incorrect Bios or “The model of the bios image does not match the bios rom currently present”

    Can some one give me some advice ? Maybe i am doing something wrong …

  • Slava

    Hello! It will made driver BIOS overclocking for Kaby Lake non “K” ?

  • Alex

    Any one knows if the updated bios from 22 OCT 2016 fixes the Windows 7 issue ? I cannot install 7 on the machine, i tried 3 different types and i get BSOD after the 1st installation (before the 2nd to continue). Windows 10 works without issues but win 7, no chances …. :(
