Your config seems very close to what I posted, good job! Word of advice, if you are running two cards that are the same, you dont need to specify each one For example:
--scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 --thread-concurrency 8192 -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale --gpu-memclock 1500 --gpu-engine 1080
Will set your cards to the same settings (youll only need to comma them if you are running different cards). Thought Id share this so you dont have to type as much when you remake your settings. Less of a chance of miss typing!
