Wish I could post this in the relevant topic but, oh well, maybe someone here has an idea.
I had a few systems available with 3xGTX590s (2 in SLI, 3rd not) but each time I tried to run cgminer it would crash and Windows (7) would ask me if I want to close the application or debug it. Is there a limited number of GPUs that cgminer can handle on a single instance? I can run 6 separately using -d0 -d1 etc, but that is annoying and is why I liked this program so much since it was able to automatically run on all GPUs available.
Systems with 2-3 GTX580s (or lower series cards) seem to work fine so far, even with SLI enabled.
If anyone has any suggestions to try I would be grateful.
