Does it make any difference if you boot with just one card?
Not yet, I will try that tomorrow after work since the system cannot be warm.
Swapped cards, no difference. Reset BIOS with the cards swapped and it works, only difference is that windows wont detect the 2nd card now so now SLI for me. I will swap cards again and try.
Ok swapped back the cards, same issue. On cold start (graphics card is cold) I get no display at all. If I let the computer run for a minute then I shut it off and on again the card works normally. It really feels like I got one of those bad cards that Gigabyte recalled.
