Can someone give a setting for R9 290 Tri-x non-x mining X13mod ??

I'm using this settings  for now and they give me 2.88- 2.90 Mhs :

"xintensity" : "512",
"worksize" : "128",
"kernel" : "x13mod",
"lookup-gap" : "2",
"thread-concurrency" : "20481",
"gpu-threads" : "4",
"gpu-engine" : "1020",
"gpu-fan" : "0-0",
"gpu-memclock" : "1500",
"gpu-memdiff" : "0",
"gpu-powertune" : "20",
"gpu-vddc" : "0.000",
"temp-cutoff" : "85",
"temp-overheat" : "75",
"temp-target" : "70",
"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "1",
"failover-switch-delay" : "60",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"log" : "5",
"no-pool-disable" : true,
"queue" : "0",
"scan-time" : "1",
"tcp-keepalive" : "30",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"

Does anyone has something better

Why not?!?

Good to know
Thank you

I had the same problem and what I did is to restart the miner and everything is back to normal for now. But I think that the rounds that were reported with "0" ,even if our rigs worked perfectly, will not be taken into consideration for our profit calculation. Our loss
Will have to wait and see what the dev will have to say.
