Maybe it's just a discrepancy between the software voltage setting and the measured voltage?
Maybe, or your card might overvolt a bit, mine doesn't which is why I only got to 935MHz before flashing to the Gigabyte vBIOS. The Gigabyte vBIOS actually lets me go all the way to 1000MHz on the GPU, way over what the stock vBIOS could do, but it just needs a bit more voltage to get it stable.

Unfortunately I'm currently stuck on 5830 vMod research for RBE. Those BIOSes don't contain the voltage registers I'm used to use for modding (since the cards aren't equipped with a voltage controller I know how to program such as VT1165MF) or they don't kick in.
Sorry for being unable to announce better news...
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
