I'm using 2 files (start.bat and config.txt) with Claymore and AMD card :

start.bat :

setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
NsGpuCNMiner.exe
pause

config.txt :

-o stratum+tcp://pool.bitsum.uz:3333
-u yourwalletaddress
-p x
-li 1
-mport 0
-allpools 1
-nofee 1


PS : -li 1 if you want low intensity (avoid some lags). nofee 1 (because if devfee pool doesn't work, program stop and need to restart).
