Thank you Bobbylite!!!! I think your right with the multi and all. But we have to take in account that there will be some n00bs as well who want to try OC'ing and maybe don't know that MP (QPI and Uncore) x bclk gives them the frequency.

Moreover my P6T-Deluxe doesn't use MP but I can only choose from determined frequencies which raise when raising the bclk. Therefore other people have the opporunity to select the same speed instantly.
