Hi Marcolin0, Welcome to the ROG community. This is what I would do. I would leave pll internal overvoltage enabled, leave the vcore voltage at 1.41v and drop down to 4.7 GHz. If you can boot to windows, that would tell me you need more vcore for 4.8 GHz.

Is your system stable all the other times? This double boot is quite normal by the way.


Things to do in bios.

Enable CPU PLL it is on auto as default.

yes i'm stable,but when i have a fake boot the pc freezes at the windows screen, and I have to re-enter the bios, do exit save of the same settings and reboot ..
it'is annoying

cpu pll is enabled (internal pll overvoltage)

It means the CPU is not always fully stable during POST - you might need to peg back the overclock - CPU, DRAM timings, DRAM freq or voltages to stop this from happening. There is not much else you can do. THis is one of the side-effects of overclocking this platform.

thanks raja,i'll stay on 4.3..
have a nice evening

solved ..
my problem was the setting hd audio controller, disabling it does not happen more fake boot.
I don't know, however, explain why, but that's okay i use an external sound card, a xonar dx, maybe they went to conflict boh 🙂

I hope It can be of helpful
