btw, I edited my previous post, Turns out I'm using 1.175 vcore set in bios, while cpuz & hwinfo read 1.152 V
The setting in the BIOS or UEFI never ends up being the actual voltage that powers your CPU. First, you have vDrop. VDrop is the voltage that you see while idling, but only if you're using a fixed voltage and also only if it doesn't drop down for power-saving. Then you have vDroop, which is when the voltage droops down under any kind of load.
So, your voltage setting in the BIOS or UEFI is only for your information - no one else needs to know and it doesn't help anyone to know it either. Always go by and report what software like CPU-Z tells you. However, if you have a motherboard that's known to get inaccurate voltage readings, then it's my understanding that there's nothing you can do outside of using some kind of a physical meter device.
