hey guys im new here so i dont know if i posted in right spot but... i need help with my graphics card and motherboard.. i have a gigabyte x38 chipset ds4 with f4F bios. for some reason my gtx260 wont run in cpi express 2.0 mode.. if i look at gpu-z it says its running at pci express 1.1. if you guys can help me figure out to run it at pci express 2.0 that would be very helpful.
