How can I find the default voltage frequency curve?

They are unlimited, and it does thermal throttle on all cores. When doing so, power draw is at ~345 watts.

I am confused on why pure power draw matters. Hypothetically, it’s heat that causes it to thermal throttle. If it was a thermal issue, wouldn’t the whole system shut down, not just a cinebench crash?

Why does power draw inherently cause issues?

I haven’t done either. I’ll try CMOS. Everywhere one said to only update the BIOS if it is known to fix this issue, and none of the updated bios seem to address this at all.
