You can delete the conf file and use this BAT for 280x:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
del *.bin
Color 0A
sgminer --nfactor 6 -o localhost:4560 -u username -p password -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20 --gpu-memclock 1500 --gpu-engine 1000 --thread-concurrency 8192
Probably too late for solo, but could be a good example for the TS.
I'm getting an average of 6.210 Mh/s with this settings.
