5. Is there a specific/preferred lane (in a MacPro tower) in which to install the card?
Hi Jesse,
I don't visit here that often, but I figured I can at least answer your question, albeit almost 2 months later.
I posted this to the Resolve forum as well and got an decent answer from an actual BM rep.
"Blackmagic Design's Blackmagic PCIe cable kit is a four-lane PCIe 3.0 capable product. It is recommended for use with UltraStudio 4K Extreme 3.
It should be compatible with PCIe gen. 2.0 (4x lanes).
It does not need additional power (card is bus powered)
There is no additional instruction, the only additional consideration as with any other external PCIe is that power is removed from both host and the connected device before disconnecting the cable.
If you have any additional questions, please contact your local Blackmagic Design support office."
So, to answer your question, the card is a 4-lane card, so the best slots to install in it on an oMP (old MacPro, or cheese grater, or 5,1) is slot 3 or 4. Those are both 4x slots. You could theoretically install it on slot 2, but that is a 16x slot, which would be a waste for a 4x card.
I hope that helps.
