I can safely say this doesn't work for me at all. I'm running my card at 243/688 on the desktop (it adds too much heat to my room at factory clocks) and I just came back from a rolling TDR with 7 in a row and then a crash (not BSOD, I got the screen corruption and looping audio) while typing in FF. Pulling my 2nd displays VGA cable did nothing either. I've given up trying to solve it, and I'm fairly sure it's not gonna be fixed any time soon. MS changed something in Vista and it wasn't a good change, and they didn't test it enough. I suppose I can live with a rolling TDR and a crash once a month.
