Hi all, I've been having some fps issues in World of Warcraft and i'm finally tired of it and set out to figure out why. I did some searching and found that if my PCI-E is running at x1 it would cause this problem. I downloaded GPU-Z to check the BUS speed and it indeed said it was x1. I logged into the BIOS to try and change it, but I couldn't find a menu for it anywhere at all. I installed nTune to check as well but didn't see an obvious setting for it. Computer Specs: CPU: Intel Pd 930 3.00ghz Motherboard: AsusTeK P5ND2-SLI Rev A1 bios rev 0501 Graphics Interface: Version PCI-Express, Link Width: x1, Max Supported x16 (nvidia 8600gt) Is there some way I can change the BUS speed to x16 or is this some motherboard limitation that i'm reading wrong? Everywhere I've checked its said that the motherboard is x16. I opened the case and the slot is labelled as PCIEx16
