MY PC =

gigabyte H61m-ds2 rev 3.0 mobo (latest bios updated )
i3 3220
2 x 2 GB corsair vengeance running @ 1600mhz
seagette 500gb 7400 rpm
corsair GS 600 PSU
windows 8.1 pro 64 bit (all drivers updated )
msi r7 260x ( latest beta driver installed )

i got each n every thing updated here then why this GPU-z showing my gpu's bus interface as 2.0, i already tried to click that (?) sign next to the bus interface column but still that bus interface column switching between 2.0 to 1.1 and that benchmark of gpu-z keep running but never shows my bus interface as PCI-E 3.0 x16 @ x16 3.0 ( should be like this ) but it was like PCI-E 3.0 x16 @ x16 2.0 or 1.1 ........ any idea whats the problem ??? any help will be highly appreciated .... thanks

one more thing guys .... i just checked in the catalyst centre hardware details and that also shows maximum pci-e capability is 2.0 ....... so then i thought that maybe its something to be tuned under the bios settings so, i checked the bios settings, PEG x option is already sets to GEN 3 and still my r7 is running on PCI-E 2.0 ........ plz help if anyone of u know how that can be done .... plz .............

That's because of your processor,because i3 3220 supports only pcie 2.0
