I believe that is the 2.4GHz version. I did some research that and found that the average overclock for the Venice core with stock HSF was to 2.5GHz and the average for all overclocks was 2.6GHz.

I personally wouldn't worry about overclocking since its already running at 2.4GHz. If you had purchased a lower model 3000+ or 3200+ then it would be worth it IMO.
