EDIT: Problem solved! I just swapped the location of the graphics cards and changed the Multi-display/mixed-GPU acceleration setting in the NVCP from Multiple display performance mode to Single display performance mode. Now it seems to work - however, NVIDIA system monitor shows me that the second GPU is in 0% use all the time, even though I am noticing improved performance in games.
I have just upgraded my computer to Windows 7 64 bit (Home Premium) and bought a new NVIDIA Geforce 9800 GT graphics card to run on 2-way SLI. I now have one XFX and one BFG graphics card in my computer (both NVIDIA GeForce 9800 GTs). My motherboard (XFX nForce 780i SLI) and both of the graphics cards are SLI compatible and windows tells me my computer is properly set up to run SLI. My OCZ GameXStream 850W power supply is also Multi-GPU Ready. I also have the latest display drivers installed from the NVIDIA website (197.13_desktop_win7_winvista_64bit_english_whql). However, when I go to enable SLI, Windows shuts down one of the graphics cards and gives me error code 43. This only happens when enabling SLI, when disabled, things go back to normal.
The XFX graphics card is using power from my PSU, but the BFG one is low-power and does not need to be powered from the PSU - could this be the problem? Please help. Any suggestions are appreciated. Thank you!
