So I just upgraded from two 580s to two Gigabyte 670s and plugged em well onto my Asus P8P67 Deluxe motherboard, ran the installation and got the 301.25 driver. They both seem to run fine on the outside (fans running) but the problem is that only one of them is detected on Windows.
I switched the cards on different PCIe lanes but nothing, only the first PCI Express 2.0 lane with either one 670 is detected, not the second one. I also tried switching the 6 pin cables and 8 pin cables (not together) but still pointless. I updated my motherboard BIOS and that didn't help either.
Please help me?
