Hello! GPU-Z shows, that my video card is running at PCI-E x1, thou it is put in x16 slot. I know that cards go into lower mode for power saving, but during gpu-z render test it dont change!

Gigabyte B85M-D3H
Corsair CX500

Is the graphics card in the slot closest to the CPU?  There are two PCIe x16 sized slots but only the one closest to the CPU is wired for x16.  The other is a x4 PCIe 2.0 slot.


Have you tried removing and firmly reseating the card?  Make sure it "clicks" firmly into place.  That is my main suspicion - that the card is making poor contact.  Cleaning the contacts on the card with a cotton bud and isopropyl alcohol or electrical contact cleaner might be worth a try.


Are there any devices showing problems in Device Manager?


Has Windows been installed freshly since the motherboard and CPU swap?

It is put in highest slot (http://imgur.com/po6tCCA)

I tried reseating card, it clicks when place it. I tried to place it in x4 slot, but Pc didnt start (i think card wasnt completly placed, i could do it without putting too much force in it). I reinstalled Windows after changing mobo and CPU - when i did that i had problems with HDD i think, everything was much slower but after changing SATA to AHCI if i recall right pc got little faster.
