read your mobo manual. just overclock it one step at a time,..also raise the vcore settings. i've seen these overclocking sites before,..and theyre a great help. just one piece of advice,...use arctic silver 3 between your cpu and fan/heatsink. great air inside your case,..doesn't necessarily sufficient heat dissipation from the cpu. the air inside my case,.goes between 29-32C....but my cpu temp falls between 38-42C under full load.
by the way,..3.2ghz is already fast...you're one of the lucky ones who can afford this. overclocking it isn't necessary, buddy. its not always important to have the fastest pc around the block...just a piece of my mind,....besides you just might ruin a perfectly good 3.2ghz cpu with OC
