I have an Asus P6T and 2 EVGA GTX 470s running in SLI. The cards got hot, so I put an after-market cooler on one of them. The problem is that the one with the cooler will only fit in the bottom slot (PCI 2.0x16_2). What that means is that it is recognized as "GPU 2" and isn't the primary display card -- it doesn't do the hard work. I NEED it to do the hard work so I can take advantage of my new cooler. But in order for that to happen, I need PCI 2.0x16_2 to be recognized as PCI 2.0x16_1, and I can't figure out how to do it. I've googled, checked asus' website, and read my motherboard's manual. After checking the bios settings, I don't see anything (irq settings?) that looks like it would do what I'm wanting it to. So, I'm looking for some help. A practical solution, a creative solution -- if you have any kind of an idea, however outlandish, let me hear it. I even entertained the idea of physically re-wiring the mobo, but I have a feeling that would be practically impossible because the traces are probably very small and hard to access.
