Maybe these configurations can help any one with SCRYPT-JANE
I have 2x R9 290 ASUS - get 550-600Kh/s at 1 Card so 1.1-1.2Mh/s
here are my configs in BATCH data just replace everything in solomining.bat
--scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -d 0,1 --thread-concurrency 8192,8192 -w 256,256 -I 13,13 -g 2 --lookup-gap 2,2 --gpu-powertune -20,-20 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale --gpu-memclock 1500,1500 --gpu-engine 1080,1080
Your thread concurrency is way too low (that one is for 7970/280x cards) as well as intensity.
I use 20481 but there are many TC's that work. For intensity, I use 20.
