Hello,
I have just got a X58A-UD9 mobo and installed 6 x EAH5450 Silent 1GDDR3 video cards as I need to run 18 monitors from one PC. The problem is no matter what I do, I can only get 4 out of the 6 cards to work. 2 just get an error code 31 and says the driver cannot be installed. I have reinstalled drivers etc, verified the cards work in another PC (which they do) tried adding auxillary power to the mobo and also tried without it and still nothing. These cards only use 19 watts of power so I cannot see this being a power issue from the X59A-UD9 board. I am running a i7 980x processor stock, not overclocked and have 12 GB of Triple Channel RAM so should be no issues there. I have been beating my head against the wall all day and am out of ideas on what the cause of the problem could be. Is there any PCI exansion slot tweaks needed in the BIOS to run 6 graphics cards instead of 4 or some other funky thing I am missing? Any help at all would be appreciated.
