    Multi GPU support

    by produktionshuset » Wed Jul 27, 2011 1:46 pm

    Im about to shell out a ton of cash on a macPro (when the rehash happens) - sofar i've been using triplehead2go on mbp's with decent results - as the desktop gpus are far more powerfull than the mobile ones in laptops/imacs.
    I was hoping that it is - or will be possible to:

    a.) use 2 raphics cards in a mac pro ( judging from current setup that would result in 1 output for the desktop - 5out of 6 for madmapper.

    b.) - this is where it gets tricky: 1 output for a lcdscreen, - 5 outputs for a combination of displayport/dvi triplehead2 go's for a combined madmapper "workspace" of 15 projektor outputs). (insert evil grin here).

    Hows that sounding Boris & Co? :-)

    only one 5870 will fit in mac pro tower

    and you can only use one of its dp outputs at a time

    I had the same idea to use 2 triplehead to go ... but only one dp and one dvi out work from the large card....

    I managed to have it to work with all 3 outputs and 2 cards (meaning 2 DVI and 4 MDP) but only if everything is wired in VGA… I did it once and it worked fine and I had to do it again and everything was connected in DVI/optical and I could only have 2 outputs on 3 for each card (2 MDP or 1DVI and 1MDP…)

    This is very problematic and not said in the tech spec of these cards…

    What setup of triplehead's2go did you use? - i got the digital (dvi) atm, but it seems like you'd need to get the DP version for the best setting - also in terms of using all 3 outputs
