MSi boards ship with fuzzy logic, it seems to be an easy way to try fsb oclock.... I don't know if it is just an MSI product or standalone....
Basically it runs a little 3-d demo to put some processor workload, then steps up the FSB slowly, tweaking voltage as it goes until the system locks up, then upon reboot lets you go to its last detected stable setting.
However, I found I could get better results directly from BIOS.... however, if you completely want to avoid bios it seemed an effortless way to get a little extra....
