hi, i'm getting this error, can i know what does it mean?
trying to run GRS mining on SGminer 5.1.1 using AMD R5 M330 on my laptop.

[10:19:45] GPU 0 found something?
[10:19:45] [THR1] OCL NONCE f62c2900 (4130089216) found in slot 0 (found = 255)
[10:19:45] [THR1] GPU0: invalid nonce - HW error
[10:19:45] [THR1] Discarded cloned or rolled work
[10:19:46] GPU 0 found something?
[10:19:46] [THR2] OCL NONCE 3d960300 (1033241344) found in slot 0 (found = 255)
[10:19:46] [THR2] GPU0: invalid nonce - HW error
[10:19:46] [THR2] Discarded cloned or rolled work
[10:19:46] [THR0] Staged work: total (2) > max (1), discarding
[10:19:46] [THR0] Discarded work

these are my start.bat
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -k groestlcoin -o stratum+tcp://grs.suprnova.cc:5544 -u chowow.chowowgpu -p chowowpassword -g 4 -w 64 --no-submit-stale -I 14

my screenshot just shows all HW errors, even after i run for an hour, the HW errors goes to 1000+ and A: is 0
