I don't know how much merit there is in it but from research I've done it would seem there is a software controllable voltage controller on some cards (5830 I have has one) but only one voltage is defined in the vBIOS and not several. It would seem you could replace the voltage registers with new values, theres just no table. This would explain the difference of 1.068v and 1.15v in the Sapphire and Gigabyte vBIOSes where the Gigabyte vBIOS deffinately gave the card I have a boost, letting me grab another 35MHz from the core. I'll try just entering 1.3v and reflashing the vBIOS and let you all know how it works out, but I don't think it'll work with the current way RBE handles 5830 vBIOSes
