On your first screen shot change primary display from auto and see if you can select peg

I agree with Dude that testing it in another rig would be ideal. from searching around, the slot is 16x/0x so it is showing up as 0x because it is not recognizing the card in 16x. (I think)

one that is looking at the same mobo/gpu combo: P8Z7-M Pro Detects graphics card as PCIE 0x - Asus - Motherboards

[SOLVED] PCI Express Slot, Dead? - Tech Support Forum

From other forums, people have said that 8x would be fine because you won't go over that bandwidth Any difference for GTX 670 SLI in PCIe 16/16 vs PCIe 16/8 ? - AnandTech Forums

but I'm not sure given this: nVidia GeForce GTX 660 Video Card - Reviews, Specifications, and Pictures - GPUReview.com


corrections: here is bandwidth chart: http://www.directron.com/expressguide.html

Maybe someone else on here can test their 660 in the 8x and see what it benches?

Did that, it just switched back to auto on restart still no display.

I'm guessing that my bandwidth on the card sucks? lol


Am I looking at a faulty card? As I live outside America I think getting it fixed is gonna suck =(

Well you just bought it so it should be under warranty. If you could test it in another rig that could tell us. It might the the pci lane on your motherboard. I'm also not sure about your bios settings. We really need to have you igpu disabled to test this too.

Not to sure on how the whole return shipping thing works but i guess i'll figure it out. As for the igpu I did what you said and set it to PCI-E, when the system rebooted it went back to auto and still showed as x0. Am i missing a step?

RaviR, lets wait for someone more familiar with your BIOS so we can give step by step pointers on what you need to set in the bios. Thorsen brought up some great points, and I'm not up to speed on the lane performance to give you an answer. Also I think you should clear your cmos after flashing the bios.

Great idea Thorsen, since I have a 660 card I did that

This is the card in the bottom x8 slot

My motherboard is different, but the same for the slots. It ran heaven pretty much identical.

It seems to be running good in that slot, soon someone who knows about the lane answer will let us know. I have to travel for work today but will keep checking.

I couldn't get the exact resolution setting as you but got as close as I could. It doesn't seem to be bottle necking at all.

I found a thread with the same issue, note the last post talking about the cpu, just something else you could check.
