Recommended is what the manufacturer sets, so lowering that is obviously not 
recommended. A normal diode needs ~0,7v, so this is kind of the hard lower 
boundary, as every piece of semiconductor circutry relies on the mechanics of 
a diode. Depending on the quality of your cpu now it might be possible to set 
lower voltages, but the system might very well become instable.
