I have a gigabyte r9 280x oc bf4 with this conf
"intensity" : "13",
"thread-concurrency" : "8193",
"gpu-powertune" : "20",
"gpu-engine" : "1055",
"gpu-memclock" : "1500",
"worksize" : "256",
"gpu-threads" : "1",
"gpu-powertune" : "20"
I copied this from this topic , i have 300Khash but a lot of hardware errors , a WU of around 40 , so i can't mine anything ..
Someone has some advice ?
Switch to gpu threads 2 and thread concurrency 8191. Also 1025/1500 clocks. I'm getting 345khash from this
