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
That's not too unlikely, but still I'd have to find out where the value(s) is/are located and - even more importantly - how it/they is/are encoded. Usually there's a formula like the one which is well known for the VT1165. As long as I don't know that formula...
