All I needed to do was fakecpuid set to 0x0506e3 and also I had to switch
OsxAptioFixDrv-64.efi switch from OsxAptioFixDrv2-64.efi
After that I was able to boot. Then it was working OK.
Now I'm testing same CPU on newer gigabyte motherboard Z270mx gaming 5 - so far everything works OK just USB 3.1 does not work now (it was working full speed on z170mx gaming 5) and audio (I understand that, since I will need new kexts for different codes stuff)
I would love to fix USB 3.1 to work on full speed! If NY body knows, let me know.
If you guys have z170mx I will did share my EFI above and just.ade the tweets
@RehabMan was suggesting.
I can never let go I guess and now Z270mx is my next goal lol.
