	Hey guy's I started monitoring my GPU usage today with MSI afterburner and found that only one graphics card (560ti) is doing any of the crunching for cuda_fermi and was wondering if there was away to get the other gpu to help out?

It's got nothing to do with SLI. You probably need a line in your config file that says use all GPUs. I don't have the context right now, but somebody shall come around soon enough to answer. ____________ ****** "Ask not, what your kitty can do for you. Ask what you can do for your kitty."

	That did the trick thanks tim! I updated boinc to the beta 7.0.56 and now both gpu's are running. Did some looking around with my statistics and found a huge amount of fermi invalids too, hopefully that issue is gone also since i was finishing those within a few seconds of run time where now there taking about 10 minutes to finish.

	You were getting false -9 overflows. 560Ti are notorious for being problematic to run here - they tend to be too much at the edge of factory overclock for stable computation. (Plus a whole host of other potential problems. There was a list maybe half a year back.) Keep an eye on it and if they start spitting out nothing but overflows again, come and ask for things to check. They are difficult to troubleshoot so fingers crossed they are fine on their own now. ____________ A person who won't read has no advantage over one who can't read. (Mark Twain)
