Or are you saying the one on CDW is actually not the same card? > I've been googling around trying to figure out if UIO is the same thing as PCI-E. Supermicro has a bunch of motherboards for which the description explicitly points out PCI-E and UIO slots, which makes it sounds like they're different beasts. Or, it could be that a UIO slot is specifically a PCI-Ex8 slot? You can buy risers that convert "1U PCI-E (x16) to 1 UIO and 1 PCI-E " Supermicro's description of the card does explicitly say that it "uses a PCI Express host interface", but maybe they mean that they're using it in some nonstandard fashion? It's confusing... g.
