You have an exeminer? Where can you download this miner? Is it specific for execoin?
check OP, download link is there
for what it's worth: the only thing I changed in .bat was '--scrypt' to '--nscrypt'
the rest remains the same and hw=0, I use 1 hd5850 2gb:
exeminer.exe --nscrypt -o 127.0.0.1:9988 -u XXX -p XXX --intensity 16 --gpu-engine 870 --gpu-memclock 1145 --worksize 256 --shaders 1440 --failover-only --queue=0 --scan-time=0 --expiry=1 -g 1
