Your talking about the Gigabyte as I read that in the reviews before I bought this board.
Gigabyte gives you the voltages for everything except the DDR2 where for some wierd reason you have to chose an overvoltage figure of +0.1, +0.2, +0.3 etc etc. But it isn't too difficult to work out as the default is 1.8v and then you just add the 0.1 to make 1.9v. Still, they should have had it displaying the voltage instead.
