I used Everest Ultimate and the actual nVidia control panel. I gave up on the whole thing and returned the 1210 to the upper 4X slot, as it just wasn't worth the hassle. Like I said, I benched it in HDTach and saw absolutely no difference between 8X and 4X (when I had it working in 8X) in my setup, so I really don't lose anything. Also, I really think this has to do with the fact that I am using a pci-express 2.0 video card (8800GTS 512) and you are using a pci-express 1.1 (8800GTS 320/640). For some reason, of which I have no idea as to why, this is what is causing my issues.
