ivanov Posted August 10, 2013 Share Posted August 10, 2013 (edited) Something weird with my setup. Z77 FTW works ok with e.g. GTX 580. But when I put one of my HD 7970 there is no image at all. 7970 cards work ok with another boards. When I put GTX 580 and change "Fast PEG Initalization" to "off" and then switch card to HD 7970 I got an image, but board always hangs during booting and nothing can be done. I also tried switching PCIe to GEN 2.0 and disabling Intel GMA, but it didn't make a difference. I checked all official BIOSes: 1.10, 1.12, 1.17, 1.21 and 1.22 - still the same issue. I am struggling with this for hours... I guess it is something with PCIe settings, but I have no idea what to change apart what I already changed.
