Your range in the BIOS will go higher, setting the jumpers on the slocket higher.
I've got the jumpers on my slocket set at 1.9v, and the up to +10% in the BIOS (2.5, 5, 7.5, 10%) gives me settings of 1.9, 1.95, 2.0, 2.05, 2.1 w/out opening the case.
I've got a Soyo 6BA+III, but the BE6 will work the same.
