Without doing anyrhing to my FX4100 CPU 3.6GHz It's running at 4.2GHz, according to CPU Z. Also my bios shows this figure. How could this be? only got my PC last Tuesday and I've not altered anything (I wouldn't know how)
hmmm, i think that is your turbo speed but shouldn't be there permanently and at that speed, it will only be using 1 core (its exactly the same with my CPU)
