I am referring to this
review of the aforementioned board (the "E" only type ,no "Plus" stuff) on my mobo (BIOS rev. 1002) I can only set the RAM voltage up to 2.1 units ,so how come they can go all the way to 2.45 (as can the P5B-E Plus)?

And if it's possible ,can I flash my current board with one of the BIOSs for the "Plus" variation as they are (apart form the solid-state capacitors) virtually the same?
