    I have searched the forums but am still a bit confused. Any help would be appreciated.

    For the early 2009 macpros with PCI x2 slots (2 at 4 slots and 1 at 16), can I use a PCI-X on a PCI-X2?

    I am looking for an esata card but i haven't found any that are in PCI-X2, many are PCI-X...

    Thanks

    You cannot use ANY PCI-X slots in any of the Mac Pro series or the last revision G5 as they use PCI Express (PCIe) and the two are not compatible. If they are actually PCIe cards, then yes, you can use a slower card in a faster slot; the slot will slow itself down to work.

    Don't you mean PCIe x2 rather then PCI-X?
    There's no such expansion called "PCI-X2" BTW.

    Using the correct 'wordings' and terminology would help soo much. :)
