Guys after a while of having my AMD Athlon 64 x2 5200+ at stock speed (2.6ghz), I've decided to try my hand at overclocking it. I'm a bit of a wimp though, and afraid to try it (the nightmare of my computer blowing up is a common one I'm sure). Would anyone give me a few hints as to what kind of speed i could acheive with it with a Zalman Aero flower Heat sink on it?
