Yeah i tried switching them too.
I managed to activate SLi at least, but it's very unstable.
Like if i start any 3D-aplication such as games the screen turns black as he usually does while starting the game, but i then stays black.
the system and game is still working since i can hear the sound of the game but the screen will stay black until i manually crash the PC and reboot.
any advice somebody?
Intel i7 870 @ 2.93 GHz, Asus Maximus Formular 3 Motherboard (SLI ready, no HyperSLI needed), Windows 7 Ultimate 64 bit, 8 GB Kingston DDR 3 RAM and as i mentioned my EVGA GeForce GTX 580 as my primary card and a NVIDIA GeForce 470 as secondary.
Thanks for the advice
