The BIOS isn't the issue Simao, it's the Gaming Center with Turbo Gear that's the issue. The BIOS is fine.
When you change the profiles in the Gaming Center, that's when excessive amount of voltage is applied (1300mV ~ 1400mV+) and OVERRIDES it in the BIOS. Then to address the issue, you either have to change profile back to "Standard" and uninstall the Gaming Center and remove all traces of it completely, or you edit the BIOS and flash it like I did and define your own settings manually. This will prevent thermal throttling as well as TDP throttling as what people have not mentioned about the "Extreme" profile, it does not raise the TDP 45W to 75W that even XTU allows, which is why cuniac had terrible performance with his G752VS under that profile.
EDIT: miguel pereira and I have no problems now regarding temps, using either ThrottleStop or BIOS for it. The Gaming Center cannot be used unless ROGTurboGear_G752VS.xml file is removed before installation (this controls the profiles and functionality). This should allow people to still use the Gaming Center to control the lights and various macros in one utility (haven't fully tested everything there yet).
Also, Sonic Suite 2 can be installed as stand-alone along your Realtek audio drivers without requiring the Gaming Center to be installed.
This is using a different version of the ROG Gaming Center with that XML file removed.
You'll want to load the standard profile first (restart if it asks) and then remove the Gaming Center after it has synced properly with the profile, make sure there are no left over folders or files afterwards. Then make sure to remove that XML file before installing the Gaming Center again. It can then be used for anything else but to OC. After that, install XTU or use ThrottleStop to change everything else for the CPU.
If temps are still high, just run ThrottleStop and in FIVR, just Reset Voltage so it puts it back to Adaptive instead of Static (in case BIOS is still configured to Extreme profile using Override).
That's all there is to it.
