    Hi, im running Vista on my macbook pro 15"
    And it has a 9400M videocard, and a 9600M.

    When gaming, it only uses the 9600M. Is there a way to let the 9400M and the 9600M run at the same time?

    Thx in advance!!!,,

    Apple hardware doesn't support Hybrid SLI, so its not possible.

    I'm not completely sold that this is a software only issue because if it was, I would have expected someone to be able to enable this in windows (via bootcamp) or hack it to work within OSX.

    Nvidia's site doesn't list the 9400M nor the 9600M GT among the cards that support GeForce Boost technology. I'm inclined to believe the support isn't in the hardware.

    Do you know what happens when you SLI non-like cards? Clearly not. I suggest you go find out, and have a look at the difference in specs between the 9400 and 9600. There would be NO POINT to doing this, it would get you less performance, not more. As result, the Nvidia hardware does not support it, nor will it ever.
