I'm starting to this something is bottle necking... so mining with this:
"gpu_threads_conf" : [
{ "index" : 0, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 1, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 2, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 3, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 0, "intensity" : 1000, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 1, "intensity" : 1000, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 2, "intensity" : 1000, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 3, "intensity" : 1000, "worksize" : 8, "affine_to_cpu" : false }
My machine mines at 5,000 h/s, with the 1920 threads running faster than the 1000s.
Running with
this:"gpu_threads_conf" : [
{ "index" : 0, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 1, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 2, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 3, "intensity" : 1920, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 0, "intensity" : 1500, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 1, "intensity" : 1500, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 2, "intensity" : 1500, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 3, "intensity" : 1500, "worksize" : 8, "affine_to_cpu" : false }
...produces 5,000 h/s, with the 1920 threads running slower and the 1500 threads making up the difference..
