i don't think you should worry about overclocking your CPU. I had a Barton 2500+ that just would not overclock. Unstable. I bought another one and it overclocked great (3200+ speeds).
Bottom line is that some processors just come out better than others, meaning two processors that are the same make, speed, mfg.
Also, are you going to get a huge increase in performance if you could overclock it?
