I got the 2nd Nvidia card working after figuring out the config format, but for the first time in several days - that I'm aware of - I've had idle cards. It's weird to see one card getting work and the other not, I guess just luck of the draw. I've hit a small snag, I can't find a way to interact via scripts with the 2nd F@H client. Any command connects to the default 36330 port, I need to connect to 36331. I guess I will need to run both of them under the same client. I would already be doing that, but haven't been able to add a 2nd slot with the correct OpenCL assignment.
