I talk about the power-supply on the mainboard, there is a power-supply too. It
has several phases and switched between them to supply the cpu with a lower
voltage then 12v. This is called the switching-frequency, you need to change
the settings of this within your bios. This makes your system more stable, next
thing is line load calibration. Dont set this to extreme, dont set this to
regular. I gues your capacitors run empty on regular and on extreme its
overheating but i dont know because i cant see its temperatures.

The power-supply of b350-motherboards has 4+2 phases like also some of the
x370-boards, thats not enough to make the cpu entirely stable. Its running out
of power. Besides this it also overheats like hell.

Buy a motherboard with more phases, you can identify them by looking left to
your cpu, the black blocks. These are inductives, counting them makes the total
of phases. I know it because i develop such things.
