I'm not sure how to overclock it properly above 3.2ghz. I have a decent cooler, zalman cnps 9500nt with manual speed control. Overclocking to 3.2 is fine because you can d oit on stock voltages. So far i tried overclocking it to 3.5 ghz on 1.425 volts. it wasn't stable. Does anyone know how to add voltage increments that will make it stable. I could try just adding 100 mhz increments and adding a bit of voltage but at the moment can't, also fear crashing the computer too many times. Anyone know how to overclock stabally with phenom ii 720 above 3.2ghz? I have a XFX 8300 motherboard.
