OK...I have the new Jan 2008 MacPro, and found a puzzling thing. I could NOT open the Expansion slot utility...it said it does not work for the machine I have. Huh? So I looked into it and found this:
"Mac Pro (Early 2008)
The Mac Pro (Early 2008) computers implement PCI-E revision 2.0 which support twice the data rate per lane as the PCI Express revision 1. Slots 1 and 2 are both x16 revision 2.0 slots. Slots 3 and 4 are both x4 revision 1 slots. Placing a revision 1 card in a revision 2.0 slot, or visa-versa, is supported and results in a revision 1 link.
The number of lanes for each of these slots is permanently set for the Mac Pro (Early 2008). The Expansion Slot Utility doesn't apply."
Slots 3 and 4 are x4 slots...hardwired as x4 slots. Slots 1 and 2 are the x16 slots. SO...my Fibre card in slot 4 is only running at 2Gb instead of 4Gb, and the Kona Card isn't running at full speed.
With this new config, is it still advisable to run the Kona in slot 3?
Seeing what you all think. I e-mailed an AJA contact this same question.
