I use a config file below, Its kind of customized to my r9 290 so you may have to tweak that
{
"pools" : [
{
"url" : "Yourpool",
"user" : "Worker.name",
"pass" : "x"
}
],
"intensity" : "21",
"vectors" : "1",
"worksize" : "256",
"kernel" : "qubitcoin",
"lookup-gap" : "2",
"thread-concurrency" : "3500",
"shaders" : "2048",
"gpu-engine" : "1000",
"gpu-fan" : "40",
"gpu-memdiff" : "0",
"gpu-powertune" : "20",
"gpu-vddc" : "0.000",
"temp-cutoff" : "105",
"temp-overheat" : "93",
"temp-target" : "75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "1",
"gpu-threads" : "2",
"gpu-platform" : "0",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "1",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
How much MH/s do get with this config?? Why do you have "scrypt" : true??
And i think you missing "difficulty-multiplier" : "256" this is needed for the qubit algo.
