    How does x4 bandwidth pci-e slots effect GPUgrid performance?

    Anyone know? I may be getting a UD3 p67 board that has a second x4 slot. would it be worth putting something there to run?

    do you have to be actually running SLI for GPU grid to pick up on the second GPU and make use of it? I have never done it in practice but I don't see why it would need SLI...

    Hurry someone try it

    Good to know.

    I knew we didn't run it in SLI but I didn't know if the board would recognize it without.

    I don't even think gpu will see the second card if run in sli; must be disabled for the grid.
    There is no difference running 4x slot; however there will be a slight loss on second card for running multiple gpus on one system
