Hi,
Since LTC became way less profitable then BTC, i figured i switch for a while.
Looking at different threads i setup my script like this:
cgminer -o stratum+tcp://mint.bitminter.com:3333 -u User_Worker -p xxx --thread-concurrency 8192,8000 --gpu-fan 85,50 -I 18,18 -w 256 -g 1
This yields some weird result:

Not accepting any shares. Any hints on what i could be doing wrong? (using cgminer 2.11.4)
Thanks
