BIOS Settings Demystified

“CPU Vcore
This is the voltage supplied to the CPU core. Unless you are
overclocking you should leave this at the default setting. However,
if you are overclocking then you might need to give the CPU a
little more power to be able to keep up with clock frequency. By
increasing the Vcore you are providing the CPU with stronger clock
tick signal.

“The flip-side however is that your CPU will run hotter, so you
need to make sure that you have adequate cooling in place (usually
it’s not the Vcore setting that damages a CPU, but the extra heat
that this generates).”
