Allright, I’m at work and I just found out that the 2008 Mac Pro can’t open Expansion Slot Utility. I clearly didn’t read that the slots are permanent.
So in other words, slots 1 and 2 are 16x PCI-express 2.0 while the other two are 4x, PCI-express 1.0…
So far, so good. as I said in previous post, I’m running an eSATA RAID controller and BMD Decklink HD Extreme in the latter ones. Hurrah!
