I've got a ConRoeXFire - eSata2 mother board. I've been running one ATI HD5670 graphic card in the AGI slot with no problems. I purchased a third display and another ATI 5670 graphic card wanting to run three displays and set up the 2 cards in Crossfire. I've struck out on doing either one. After digging around I realize that the second card is not showing up in the device manager. Both cards work when I plug them into the AGI slot and neither works in the PCI express slot. I've plugged in the power supply SLI/XFre connector but still no luck. I've stared at the Bois for hours and can't see anything that I can change to make the PCI express slot work.
Anxiously awaiting your much appreciated response:-)
