    Hi,

    as mentioned here

    http://forum.notebookreview.com/gaming-software-graphics-cards/682968-sli-opengl-not-working.html

    I can't use SLI in OpenGL Applications like Rage,Brink,Furmark etc..

    I've come to the conclusion, that its a general problem of the machine.

    OpenGL tends to select the card the monitor is connected to (which is the secondary card in the d901 according the nvidia control panel).

    Furmark even shows that it only uses GPU 2 while GPU 1 does nothing at all.

    Could anyone with a SLI Setup try if SLI is actually used by any OpenGL Application ?

    My 2nd 8800M board died. So going from memory here. But hopefully you have SLI enabled through the Nvidia Driver? You do have to turn the feature ON.

    I don't know if you have run into the same problem, but on some games, I had to select the first board as PhysX in the Nvidia Driver to get consistent game loads. Set to Auto Selecting was not working on some games. Hopefully some of this helps... AlanP

    Thanks for the info. Yes it is enabled and working with every single Direct 3D game I have. Every OpenGL Application puts load only the second card. Not even the Visual Indicator shows up.

    Unfortunately changing the PhysX Setting doesn't do anything. I even set it to CPU.
