Vio setting.

Got a MSI 815e pro.
There is a setting for Vio, its on auto.
Setting ranges are 3.3 - 3.8 I believe.
Been having mad problems getting my 700cb0 to clock well.
Cant hit the 133 FSB, gets to initing the video card and stops.
Will pumping this voltage make a difference?
How high can I set it safely?
