This may not be much of an overclock for most, but to me its almost as good as my good ole 3500+. I got my Sempron 2800+ 64 to 2402.7mhz or 2.4ghz that is a 800mhz overclock I could go much more, but I want to wait until tomarrow when I get a Zalman 92mm heatsink fan or a thermaltake Big typhoon...
