Ok, i've wanted to give it a try to 5.1 one more time, yes it mines, but has a problem, at least with my old gpu's. HD5xxx
-------------------------------
seems that these commands does not work in 5.1
"gpu-fan": "0-100,0-100,0-100,0-100",
"auto-fan" : true,
"temp-cutoff" : "95,95,95,95",
"temp-overheat" : "85,85,85,85",
"temp-target" : "80,80,80,80"
make sure your clock speeds when mining
are really equal to those you set in your conf file
Yes, speeds are equal, sgminer 4.1 works perfect with same speeds and fan control works, but with sgminer 5.1 fan control doesn't work at all.
Thanks for comments, i hope that bug will be solved soon.
