nice software unwinder, any chance of getting support for these cards too please? they do have a software programmable voltage controller, and come with asus smart doctor which allows voltage changes - the thing is that software doesn't allow an overclock more than - 830/850 which kind of defeats the purpose of being able to overvolt
This forum subsection is not that big yet to be unable to find the answer. Use search please, 4770 voltage control was discussed a few times already.
