hi,i am trying to overclock stm32f4 but i have two questions

1:if i overclock stm32f407vg to 200mhz from 168mhz will it decrease lifetime of the chip?

2:what's the voltage required by stm32f4 to run at 168mhz.

I'd be less worried about physical damage/wear than not fully understanding where the critical paths in the design are, and transparent failure.
