So... let me get my head around this. The original bios that comes with the 7950 IceQ's is voltage locked, the only way you can adjust the voltage is by using 'Constant Voltage' in MSI Afterburner, thus breaking powerplay settings.
You got around this by using one of the Gigabyte 7950 WF3 bios, which then enabled the voltage slider to set any voltage you want, and still keep powerplay settings.
Is that right? I'm just trying to suss out these cards, as I might get one myself. The amount of people who have these cards, and the amount of info available is kinda vague.
