So I recently decided to get the G752VS-XB78K. After taking it out of the box and finishing Windows Setup, I started benching and monitoring voltages, temps, etc.
To anyone that says 'clean' installs are stupid... obviously aren't enthusiasts and that's fine. I've always made a backup of the original drive that came with the pre-configured setup of Windows from ASUS onto another one or at least copied the eSupport folder out before formatting. Regardless, it is not required but it works just fine. Tired of seeing threads regarding this. Also, the NVMe drive requires the IRST driver loaded when you do a clean install of Windows during the setup in order to see it.
Anyway, back to the testing.
To my amazement, it was indeed reaching nearly 95°C almost instantly and throttling Turbo Boost clocks. The CPU 'static override' voltage was over 1.3v which adaptive makes 1.4v! So.... out comes the fun tools like AFUWIN to dump the BIOS, and AMIBCP to edit the access privileges for the additional menus and sure enough, there is an Overclocking one that's functional. You'll also have to go into the CPU configuration menu and adjust the override there for your cores as well. I'll post some screenshots. Sure enough after making the required changes in those screenshots, the temps drops to 77°C on extreme load and sometimes climbs to 80°C after a while when still at 4Ghz. This Aptio 5 BIOS is going to be so much fun to use compared to the Aptio 4 BIOS in the G751JY I had.
Now, what I would recommend doing is use ThrottleStop to find out how low you can go FIRST, before applying some random lower voltage and not be able to boot after saving it. When running ThrottleStop for the first time, you must default the voltages in its current state there to see any changes YOU make afterwards.
It's also normal for the system to power down after you adjust voltages in the BIOS and then turn back on.
This fix, literally addresses the entire issue regarding CPU throttling from higher temperatures due to the excessive amount of voltage applied under the "Extreme" profile.
I'm currently still testing things out with the machine so later on throughout the week, I'll post more up.
EDIT: Definitely uninstall the ROG Gaming Center and never use it! It affects and adjusts the settings I manually changed in the BIOS for the CPU OC.
