WU 0.118/m -> Radeon RX 580?

[johntestualfourteen]

Hi Forum,

im testing for days now and read a lot of posts here. Im working with a Radeon RX 580

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

and my sgminer.conf looks like this:

{
"pools" : [
{
"url" : "stratum+tcp://xxxxx",
"user" : "xxxxx",
"pass" : "x",
"algorithm": "darkcoin"
}
],
"thread-concurrency" : "24550",
"intensity": "22"
}

Has anybody an idea to increase my wu? I dont know what to do now and i cant find a proper solution. Trust me, ive tried to find it.

Thanks in advance! Cheers.
