eVGA tech support response:
Answered By Xxxxxx X (2/25/2009 12:36:35 PM): Xxxxxx, Try scaling the system down to one GPU and try each of them. If the cards go red, it generally means there an issue with power either from the psu or the pcie slots. Most SLI certified motherboards should let let you put the cards either next to each other or the first and third pcie slots and try them in each configuration as well.
I do not know what scaling down is... I did send a reply to this.
