Does anyone know why my SGMiner on the Suprnova has a huge number of HW errors (I reduced the intensity but not helping):

My .bat file is:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
sgminer.exe --no-submit-stale --kernel timetravel10 -o stratum+tcp://btx.suprnova.cc:3629 -u LuckyLuciano.Bitcore2 -p 2 -I 19
