Asus EN8800GT & Gigabye 8800GT SLI Problem I have recently bought a EN8800GT 512MB Glaciator graphics card. Then I got a Gigbayte 8800GT 512MB Turbo Force Edition as a gift. I have a XFX 780i SLI Motherboard I decided to enable SLI. I installed everything correctly. My computers configuration: Intel Core 2 Quad Q6600 2x 2048MB OCZ DDR2 2x 1024MB Kingston DDR2 250GB HDD 500GB HDD 2x WD Velociraptor 300GB 850W Silver Stone Zeus Windows Vista Ultimate SP1 Both Cards were recognized by device manager but when i enabled sli in nvidia control panel system crashes. both cards works perfectly individually.
