voltage overclocking

could somebody give me a good site for overclocking via cranking up the voltage coz dat the one thing i dun now much about and im to scared to try in case i cause a meltdown to the cpu

all help will be very thankfull

i know with AMD chips, and probably Intel too, a good, safe maximum voltage increase is 10% over stock. If your cooling can handle it, Ive seen even higher. I personally only go about 5% over stock voltages. Memory and videocard voltages I think are a little different, most mobos limit the max amount of volts you can run through the memory, so you shouldnt have to worry too much about that.
