As far as I know, the max Vcore of the i9-9900k is 1.52v and the system should BSOD if it reaches that threshold. I have no idea why it does this. This started happening about 2 days ago. The voltage was much much worse initially. My CPU would reach 1.8v in load with temps of 55-60c. I tweaked some voltage related stuff in the BIOS and got it down to 1.5v. How is it that my CPU would reach 1.8v without BSODing or overheating? This makes no sense.
