Are you sure it runs with 1 card now? You may not have set cud a back up again properly
Yes, It's been hashing for the pass two days on one card.Anybody else have any ideas why I keep getting "Unable to query CUDA driver version! Is an nVidia driver installed?" when I attempt to run 2 750 Ti. I'm running Ubuntu mini 13.10 and drivers - 334 and cuda is 5.5
