    Pyrit wont find any GPU's when in SLI, works perfect on a single card.

    I am trying to get my machine to use 2 GTX295's in SLI when running pyrit.

    I am running backtrack 5 r3 32bit, NVIDIA 680i SLI mobo, and the cards are matching BFG GTX 295 OC's, in fresh install of backtrack 5 r3 with the latest drivers from NVIDIA, CUDA toolkit 4.0.13.

    If I boot to Win7 they work in SLI perfectly. If I physically remove the second card from the machine and boot to Backtrack pyrit lists both of the GPU's. If I install the second card in SLI pyrit doesn't find any GPUS. I have tried older drivers to no avail, and several hours of internet searches came up with nothing useful.

    Seriously? Asking BT related question on Kali forum? Funny no one answered.. Nevertheless, given your driver installation went well,

    nvidia
    -xconfig --sli=on


    Reading helps too

    Well I would have posted this in the BT forums, but they are shutdown, so I can't.

    I will try that when I get home, Thank you.

    I tried what blackMORE suggested but the problem remains as before.

    The NVIDIA X Server Settings tool also only lists 2 of the GPU's when both both cards are installed.
