I swapped my 290's round today. The card that was in slot one would only undervolt to -0.031v. Any lowering would causes flickering at idle/browsing despite it being game stable at lower voltages. Put card two in slot one (wahey) and suddenly im able to undervolt both cards to -0.056v. Passed OCCT stable and no idle flickering. Will now try for -0.062v.

Sold one of my 7990s so i'm back running three reference 290s again
Don't even need to overclock them, everything runs so smooth, happy days.
Just need to get water blocks on them and i'm done for a year or so I think (famous last words)
