So I'm new to sli but I thought it would be a good way to boost my rig while staying economical. I am having a problem however when I try to enable sli in the nvidia control panel. As soon as I toggle it on it causes my screen resolution to flicker and if plugged into the top graphics card it blue screens, when in the lower gpu it causes the screen to go black with only a cursor. The only way to remedy this after a test is to take sli bridge out and reinstall my drivers. I have 2 identical nvidia 460 GTX OC 1Gb cards and an Asus P7P55D-E PRO that is sli compatible, I also have a 750w cosair powersupply so power should not be an issue. Any advice? So far no amount of reseating, reinstalling, and reconnecting has solved anything.
