The easiest way is to go to the bios or cpu settings and change the precision optimizer so that you have a negative pbo setting. That'll reduce the stock voltage at a given frequency. It'll also potentially speed your chip up since this lets the chip boost to higher frequencies at a given power level. I think the lowest you can go is -30, but try -20 or so and see if your system is stable before trying lower values.
