*on the Asus website, to the support of the asus 1080 Ti, you have two different Bios, the original one and another silent mode with the integrated tool to flash the card, try to flash the bios of the graphics card to see if that can correct the problem.
Other thing, *did you make a clear Cmos after reflashing the bios of the motherboard and load seeting default ?

I had this issue and i did not understand what was wrong, and seeing your post confirmed the problem for me. I then saw somewhere that the 2nd 16x slot will cause the first 16x slot to go 8x if there is ANYTHING on that. I had a soundcard on mine and I moved it to the last one, which if I understand is controlled by the chipset. I confirmed that it showed up as 16X 3.0 on gpuz after.

Yeah, that's would i do as well, but I have nothing on any of the pci-e slots and it still shows x8. I know for sure that ther'es something wrong with this card because I tested it on two PCs, Maximus X Hero 0802 bios and Z87-K with latest bios as well. The Z87-K pc runs with Asus gtx 760, wifi network card and a sound card all plugged in into pci-e slots. Abosultely no issues. GTX 760 is running at pci-e 3.0 @ x16. THe moment i plug the 1080 ti into it, bam, runs at x8 as well.
So yeah, two different 1080 TI's on two different computers, all run at 3.0 x8 and gtx 760 running at 3.0 x16 on both. I wish it was the other way around.

I know this is basic but when GPU is idle and in low power mode the slot speed can be reported as x8
try a program to kick the gpu into gear such as furmark or something you can watch the pci changing from x8 to x16

When the GPU is idle it alternates between 1.1 x8 and 3.0 x8, but never to 3.0 x16. BIOS, GPU-Z and CPU-Z, all three show the card running PCI-E 3.0 x8.
I ran furmark, unigine heaven, superposition for hours and monitored with gpu-z and hwinfo64 and it was locked at 3.0 x8 non-stop.

Are your 6 + 2 pin PCI E power cables properly connected to the VGA ports of your EVGA power supply? VGA1 and VGA2? try on VGA 3 and 4. I have a friend who had the same worries and by swapping his cables he found the PCI E X16.
