Sounds like Bs to me; I just built a system with an epox 8k3a+ and OC'd it from 1333 to a little under 1500 just for kicks (I should mention, however, that I just did this for kicks and didn't keep it OC'd for very long).
From the setup of the Epox board, I'd say that overclocking was intended to be a pivotal (or at least easily accessable)feature.
Just my two cents,
