GPU is running in x1 mode instead of x16

Hello

My specs are:
Motherboard - Gigabyte GA-Z87X-UD4H
CPU - QuadCore Intel Core i5-4670K
GPU - EVGA Nvidia GTX 770 2GB
12 Gb of 1333 RAM

So my problem is that my GPU seems to be working slower than it should. I launched GPU-Z and noticed that my bus interface is running in x1 mode instead of x16. I tried the render test and turning off power saving options, nothing changed.

Here is the GPU-Z screenshot http://gpuz.techpowerup.com/16/05/25/dj9.png

I also checked Rivatuner and it said:

$000000000e Base address 5 : 0000e000 (I/O range)

Notice the line 16x supported, 63x selected.

The weird thing is, when I reseated my GPU from x16 slot to x8 slot, GPU-Z started showing that my videocard was working at x2 and I got a minor FPS increase in games.

I also tried removing my GPU and putting Nvidia GT210 instead of it. When inserted in x16 or x8 slots, my PC just wouldnt boot up, and in x4 slot it booted up just fine and GPU-Z said that it worked at x4 speed. I have no idea why would this videocard not work in other slots. It is normally seated in x16 slot in another PC.
I also inserted my videocard in another PC in x16 slot and GPU-Z showed that it worked as it should, at x16.

So I have no idea what is going on, tried resetting BIOS, nothing changed. Now I am out of ideas, maybe someone can help me?

Update the chipset driver https://downloadcenter.intel.com/download/25094/Chipset-Intel-Chipset-Device-Software-for-Intel-NUC because it comes with the pice controller driver.

If it is same. then update the BIOS. If it is still same, that maybe the hardware, the pcie slot/MB, problem.

May be bro your motherboard is not supporting cause u wrote that its working on 16x on another pc and another pc might have another mobo so check ur mobo if its good enough.
Thank You
