I try running diablo 3 and still stuck at x2. I also tried the stress test in GPU-Z, still not changing. My system: CPU: Intel Q9450 2.66 MB: Asus P5KPL-VM with latest bios RAM: 4GB OCZ Reaper Kit (2x 2gb) PS: Coolermaster eXtreme Power Plus 700W I tried changing the PCI-E us Frequancy to 100-105 and that didnt do anything. this motherboard doesnt have too many bios options. But i still dont see why this happened. if anyone has an idea please let me know. thanks.

Also is the graphics card in the top PCI-E lane? | Report abuse djxcrx88 May 22, 2012 7:49:21 PM yes, I already mentioned that the motherboard had the latest bios. And this motherboard only has 1 pci-e 16x slot unfortunatly | Report abuse omgitzfatal Graphics card Master May 22, 2012 7:52:08 PM Ok I'd run 3DMark11 and see how your score compares to other similar systems, just to find out if your card is actually running at x2 1.1 or if its a bug with GPU-Z. | Report abuse Related ressources HD7950 @ PCI-E x1 1.1 instead of x16 2.0 , please help - Forum PCI-E 2.0 x16 card on v 1.1 - Forum 8600 GTS runs at PCIE link mode x2 instead of x16 - Forum GTX 560 Ti running at PCI-E 2.0 4x instead of 16x - Forum Could a GTX480 1GB work on a pci express 1.0 x16 with good perfomance? - Forum Ask the community Publish djxcrx88 May 22, 2012 8:41:39 PM so if 3d mark gives me good benchmarks then everything is fine? Is there a way to know for sure though at what speed the pci-e is running at? | Report abuse willard Graphics card Authority May 22, 2012 9:03:11 PM Well, if you get a decent score you know for certain it's not running at 1.1 x2. That wouldn't be enough bandwidth for even the lowest end cards. | Report abuse djxcrx88 May 22, 2012 9:21:12 PM I already clicked the question mark, thats what i meant by gpu-z stress test. Still get x2 1.1, doesnt budge. I dont know what to make of this, I just wanna know if theres something wrong, or its normal. I will try 3d mark11 when i get home. one thing i noticed though is that my northbridge heatsync is scortching hot and my ram sticks are hotter than usual as well... not sure whats causing that, could the video card be the reason? it was doing that with my old gigabyte motherboard right before it got fried... I RMA'd that board and bought the asus for the mean time. but it seems to be doing the same thing | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Graphics & Displays>GTX 480 PCI-E @ x2 1.1 instead of x16 2.0> Related ressources: ForumWhy should i get PCI-E x16 3.0 motherboard instead of 2.0 ?
