SLI Problem! Please help!

[spclffred]

Ok i have two 6800ultras and an SLI mobo and everything hooked up right, i activated it in bios and in nvdia settings and its still not running both, anybody know my problem,i did have the ez card right and on both cards the green light is on, and im just wondering that if the sli is running will the bios display it at 512mb of ram or will it still display it at 256mb, and if it was working, im not sure its acutally working. is there any way to tell if it working or not.

I've read that SLI just doesnt work with some games. Maybe its the game your running?
