I have 4 of these boards and that PCI 1x number 3 does not work on them either. Don't know what's up with that. Furthermore, I think 4 cards per mobo is the max right now. It is all I can get to work in Windows 7. Looks like in the forums folks are saying that is the max the drivers will allow. Have not really see a work around. I have not had any problems at all with the onboard GFX. I have them running on all the boards for a nice little 80k/Hash bump with a 6800. I put the IG bios settings to Force on and PCI NB although on some I force the IG to be the display and that works fine too so I don't know what to tell you there. These boards are pretty solid though. I mined Bitcoins for a while with them running 3 7970 off the board before getting powered risers and beginning litecoin mining. Was very disappointed when I put together my 6 card uber rig with 2 PSUs and it looked so beastly and cool only to have only 4 cards ever usable and to find out on my own that that 3rd 1x slot is a lie. I've since found this report in several places. For future builds I'm going to scale back to older tech I think and buy used cheaper mobos. The 80khash from the APU is a cute little bonus but I can shave off over $100 like I did with a pentuim 4 dual core rig I have that runs great for $55 for the mobo and cpu. DDR2 ram though. Don't know if that will negatively affect LTC mining yet. Let me know if you hear anything from Gigabyte about this. Also let me know if you find anyone that has more than 4 cards running in Windows 7 or 8 or hell I'll even try linux if I can get it working. PS [if you count the APU I do have 5 cards going
