	Up until today I have been crunching 2 cudas at a time, now only one will run. The only thing I can think of is that I updated Nvidia driver and it changed some setting. Anyone have an answer as to what I need to change to fix this?

	If you are running the optimized apps that is unlikely to change the app_info settings. Just check your app_info and see if something is different. If not try a reboot ____________ Proud member of TSWB. End terrorism by building a school

	EDIT: Just checked BOINC under computers and it seems to think I only have one GPU. Although windows recognizes both in system and I am currently in SLi mode. app_info ? is this a file you are referring to? I also tried reverting back to previous nvidia drivers, same thing.

	A pair of 9500's in Sli mode will only be recognized by BOINC as one GPU. It has ran as two for the last month, and I have tried disabling SLI, samething As I said, it was running two CUDAs up until about 6 hours ago when I updated NVIDIA drivers. Now it thinks I only have one GPU.
