Yeah........ you're not going to be able to overclock that. Dells generally don't have any overclocking options because they don't want for you to overclock it. The only way for you to get overclocking options is to use a hacked BIOS. Google "Dell Inspiron 531s Hacked BIOS" and go from there. If your feeling adventures you can create your own. Of course if you don't do it right you end up with a bricked (pretty much dead) motherboard. You could also buy a real case and motherboard, and then go from there.
