SLI trouble

[dxdesigner]

I have just purchased and custom built a new PC. I have two SLI cards (nvidia) 512MB that I am trying to run. I have installed them/the bridge. When I try to configure it in nvidia's control panel, it is listed as only having one graphics card. I am running Win XP Pro x64. Any suggestions would be very much appriciated!! Thanks!!

If theres a problem with the drivers, it's probably the pro x64 edition causing it, as it has driver compatibility issues.

Make sure you have the SLI power connected on your motherboard as well. I've got two cards in SLI running on xp pro 64 so it can be done!
