Use:
{ "id" : 0, "intensity" : 15, "worksize" : 8, "threads" : 2},
{ "id" : 1, "intensity" : 15, "worksize" : 8, "threads" : 2},
{ "id" : 2, "intensity" : 28, "worksize" : 8, "threads" : 2},
{ "id" : 3, "intensity" : 28, "worksize" : 8, "threads" : 2},
{ "id" : 4, "intensity" : 28, "worksize" : 8, "threads" : 2}
thanks for your attention, i have try your config and same SRB miner close after loading kernel, it only work if i disable gpu_conf and use auto intensity to 0, i use that config before on srb v1.6.0 and before work fine with gpu_conf manually
I think I found the problem.
In the last line add a comma, like this:
{ "id" : 4, "intensity" : 28, "worksize" : 8, "threads" : 2},
