Hi there,


I came in mac world from little time with a bargain Mac Pro 3,1.

I upgrade memory, VGA with Radeon 5770HD,  Hard Disk -SSD with Leopard and 4 tera HD. Buy some software and want start to replace my PC win with this fantastic machine for sound working.


I would be put an e-sata card or /and a Black Magic video editing card but, I have only PCI express slot.

What can I do?

Mac Pro, Mac OS X (10.6.8), pci express

    I don't understand what you mean when you say "I only have PCI express slot". All modern version of the cards you mention ARE PCI Express cards.

    Hi Matt,


    mean I have pci express only, as the pci express 16X were I put the VGA.

    Same type. long slot.



    I just found this image on the web to give yoiu an example, and I see that here there is a little PCI express inside a long slot... so, mean I can put inside my Intensity?

    Yes. All the slots are x16 size PCI Express, but any PCI Express card will fit (most will be much smaller, and will fit in the right-hand edge of the slot, as you see with the card you have in slot 3.


    Just make sure that you use the correct speed slot for your Blackmagic card. You have two x4 and one x16 available. I don't know what speed the Intensity needs.

    Thank you so much!
    I asked on several forums but apparently no one understood my concerns. Thanks Matt!

    you have PCIe 2.0


    your GT 120 is a rarer single , not double slot wide, graphic card - the ATI 5770 and most are double width


    look up specs for your model on site like everymac.com and of course specs and manuals from Apple


    www.apple.com/support/macvpro and go to Early 2008 3,1 page


    Apple only says that there is 75W per slot and there are two add'l 6-pin power cable plugs for cards that need more than the 75W.


    It is rather "hidden in plain site" as far as your hardware specs go.
