WAIT!! Before you read any further and post, I am NOT trying to SLI these cards. I just want to connect my 17" to my 7900gt, using one pci express slot, and my 20" using my 7950gx2 in the other slot. Ive got a seasonic 500watt psu. My mobo is an asus a8n-sli premium. So not full pci express bandwidth on both slots. I get a red light on my board come on (the warning light) when i boot my pc. It just doesnt work. I can boot up , with the 7950gx2 working on slot one, but device manager doesnt even see the 7900gt. I am thinking its PSU related as Ive already got 2 dvd writers, 2 x hdd’s, and am using two PCI slots for wireless and firewire 800. The firewire 800 is powered by a molex connector.
Can anyone give me any input???
I am also having problems connecting two monitors to the one 7950 gx2 card. Great huh? The dual monitor mode in my nvidia settings is greyed out. Any ideas there?? Using forceware 91.31 forceware.
