Hi Willie, Sorry for the problems. I use two NVidia cards with nvidia-drivers and don't have any stability problems. My cards are the GTX465 & a 8400GS which are both CUDA-based. There are some very real OpenGL issues with this setup, as well as all the Flash on NVidia problems, but no stability problems. As for your setup, if I was to guess I'd start wondering if the NVidia driver supports two cards where one is CUDA-based and the other isn't. I tried Googling for that with no real results. Note: I do use an xorg.conf file on my system, as well as the newest drivers. You didn't provide much technical info about your setup so maybe that could be posted? nvidia-smi reports the correct amount of memory on my two cards. Good luck, Mark
