1) When the miner freezes, the system error window appears.

But the SRB-Miner process is still in computer memory.

The SRB-Restarter utility thinks that the miner is working. But the miner is frozen.


Not every crash can be catched, restarter works for restarting the miner when a crash occurs because of miner bug code (access violation etc.)


RX562, miner 1.8.2 - 1.8.3 - not OK
{
"cryptonight_type" : "normalv4",
"intensity" : 0,
"double_threads" : true,
"retry_time" : 2,
"persistent_memory" : false,
"min_rig_speed" : 2100,  <<<<<<<<<==============   only works if set to 100. otherwise restart miner!!!!!!!
"min_rig_speed_duration" : 60,
"gpu_conf" :
[
{ "id" : 0, "intensity" : 26, "worksize" : 32, "threads" : 2, "fragments" : 8},
{ "id" : 1, "intensity" : 26, "worksize" : 32, "threads" : 2, "fragments" : 8},
{ "id" : 2, "intensity" : 26, "worksize" : 32, "threads" : 2, "fragments" : 8},
{ "id" : 3, "intensity" : 26, "worksize" : 32, "threads" : 2, "fragments" : 8},
{ "id" : 4, "intensity" : 26, "worksize" : 32, "threads" : 2, "fragments" : 8}
]
}


Someone else also reported the 'min_rig_speed' parameter is broken and triggers much earlier than it is set. I am testing it, but so far so good.
On a rig that does 38khs turtle i set it to 36khs and it's not triggering - restarting miner.

Im using with minimal config :

Code:
{
"cryptonight_type" : "turtle",
"intensity" : 0,
"double_threads" : true,
"min_rig_speed" : 36000
}

Going to check it out in code, maybe when gpu_conf is set this parameter gets omitted, or idk.

Ok, so i think i know what is happening. Cn/R precompiles 10 kernels on miner startup. That takes some time * number of gpus in the system.
Your "min_rig_speed_duration" is 60, it is too low, because miner does not start hashing until it precompiled the kernels. So just set the "min_rig_speed_duration" to a higher number, try few minutes...
