First, Auto usually sets the highest possible, loose values on a platform for power to a component(which might be the CPU, in your case since you forgot to mention that). Then there's the matter of which platform you're running to see those types of voltages on your component.

CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
