How does your .bat file look like? Maybe the intensity value is too high for your card.
setx GPU_MAX_ALLOC_PERCENT 100
sgminer -k skunkhash -o stratum+tcp://sigt.suprnova.cc:7106 -u (myusernamethatidontwanttoshare.myworker) -p (mypass) -I 16
pause
tired i = 20 / 9 / 14 / 12 . this is not working for me.
tried lowering GPU_MAX_ALLOC_PERCENT to 70.
suprnova shows 0 hashrate. 0 shares.
try sgminer.exe instead of sgminer by itself.
