I have a system set up with the A8N-SLI and 2 HP NVidia Quadro 3400s. Everything appears to be working fine hardware wise: each time I boot into Windows, I am even prompted to activate the SLI multi-gpu mode. The weird problem is this: whenever I attempt to activate multi-gpu mode, the setting change doesn't stick. The computer doesn't restart, and if I go back into the menu, it looks as if I had never changed the setting. I have tried it with every version of NVidia drivers that I could find... and still no luck. Has anyone else had this problem and been able to resolve it? Can anyone suggest something else to try? I'm really stuck here. Thanks a lot.
P.S: I posted this in a couple places. Sorry, but I'm really frustrated after working on this all day. I appreciate any help you can give.
