running vista ultimate x64, 2.13 dual core intel, 2 gigs ram, front bus 800mhz, 2 nvidia 8500 GTs, anyways whenever i try to enable SLI through the nvidia control panal i freeze up for a sec then screen goes black with a white _ in the upper left corner of the screen then after about 5seconds the screen returns in a 800x600 res. at this point i can move my mouse around and click my start button in the lower left, but the nvidia control panal is froze on my screen and after about 1min it simply closes... then my video drivers in device manager shows yellow triangle with ! in it wont enable the installed drivers til i re install the drivers again.... i have tried drivers 175.16 175.19 and 177.89, none worked and yes i made sure to Download the drivers that said they were for vista x64.
on a side note... single card works great and no problems with any of those drivers installed..... also during that time with a single card running i can see both cards in the device manager installed with drivers and it says they are working. the only thing i havnt tried is switching the cards around... but i have had them in the spots they are now when i was running windows xp pro 32bit
