Is there any way to check that smartdoctor is actually applying the higher voltage ? Or does anyone have a copy of afterburner extreme from the 2.0 builds. I have tried with 1.6beta6 and there is no voltage control.
orson - I think you will find that your 580 is also bios locked with a voltage limit so you will need to flash the vid card bios to get past 1.213v. I did this to mine with bioses supplied by a very nice member here, all of them unlocked higher voltages BUT all of them caused issues such as graphical corruption even at stock settings, luckily I didnt brick my 580, so for now I am back to the 1.213v bios until I get one that my card likes.
