I believe I've found an issue within A-Tuner that allows changes to your system's voltages, and doesn't reflect said change within BIOS or HWINFO. I assume this is working as intended outside of the ability to apply successive voltages from merely clicking "Apply". Said voltage increase will persist through a system restart and won't always reflect in your bios. (vcore didn't change if memory serves correctly, or at least that's what I wrote down.)
I believe this may explain some "new" boards that appear to be performing outside of agreeable deviant. Sadly, in my case, I didn't notice my stock configuration allowed me to boot at nearly 1.5v to the core.
She's stable though.. Just needs a new exorcism and some holy water to remedy the humming sounds.
Sadly no good screenshots due to initial panic. I did let the volts drop, reboot and immediately push through a Cinebench though.
In for a penny, in for a pound eh?
You can reproduce it using default settings (on auto) and adjusting voltages in A-Tuner. If that doesn't work try the fatality's link.
Might break out a pixie measuring device but probably not.
Be safe, kids! Don't be like me!
