Motherboard Bottle Necking Graphics card speed?

[Flokkee]

Hey, so I guess this is something I'm not super familiar with. Somewhere on the internet I found a post stating that the PCI-E Bandwidth is used by or could be used by other components on the motherboard. Well I have a PNY GTX770 OC(Enthusiast Edition) Graphics Card and my GPU-Z report as well as HWinfo state the that graphics card is running at x4 when the slot its in (Tried the first second and third slots on my motherboard) x16 slot on the mobo.

PC Setup -
PNY GTX 770 OC
Asus Z87-A
Thermaltake 700w
i5 4670k

Here is a link to the gpuz screen - http://gpuz.techpowerup.com/14/05/12/369.png
The ? mark next to where the bus speed is listed.

Essentially, my question is what could be causing it to run at a lower speed and how do i get it back up to where it should be...

Well from what I understand, pci-e 3.0 is twice as fast as 2.0 which is twice as fast as 1.0. This means that the card runs as at x16 on pci-e 1.0 but only needs 4 lanes under pci-e 3.0

I think it is the bad reading from the software, you can try to clear the CMOS, and also reseat gtx770 too, and rerun the gpu-z.

Tried both reseating, and CMOS. cleaned the PCI-E lanes, as well as the cards "teeth" still not getting a connection at x16. Noticed something that stated that the max speed is 8.0GB/s and it is getting that. Does this just mean the lane is giving out a bad reading? I'm super confused now.

Or you can try to run the benchmark software to see what happens, Do you have other hardware like sound card or pcie add-on card in othe pcie slot?

Why did it choose yours as best solution... I did many benchmarks to see, as well as the one that rendering thing through gpu-z and its solid at x4. There are no other cards installed into any if the PCI/PCI-E slots not even the mini ones. its just 1 GTX770
