now i'm using this settings --gpu-threads 2 --thread-concurrency 8192 -I 13
setx gpu_use_sync_objects 1
setx gpu_max_alloc_percent 100
any help??

For 79
50 you must set --gpu-threads
1 if i set --gpu-threads
1 --thread-concurrency 8192 -I 13 my hashrate decrease

also, if i try to use highter value of I with --gpu-threads 1 i have the same problem with too much hw error.
