Did you check the temperature? Try a lower intensity setting.
Also I think you can remove these lines if you use sgminer:
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"vectors" : "1",
"shaders" : "0",
"scrypt" : true,
Thanks for your advice!
I haven't made much progress, I always get some kind of display driver error now on the 5850. The R9 290 runs fine though. Current config for both GPUs: (first being the 5850, second is the R9 290)
"api-allow" : "W:127.0.0.1",
"api-listen" : true,
"api-port" : "4028",
"expiry" : "120",
"failover-only" : true,
"kernel-path" : "/usr/local/bin",
"log" : "5",
"queue" : "1",
"scan-time" : "60",
"auto-fan" : true,
"gpu-threads" : "1",
"gpu-engine" : "725,1000",
"gpu-fan" : "0-100,50-90",
"gpu-memclock" : "1000,1350",
"gpu-reorder" : true,
"intensity" : "13,20",
"temp-target" : "70",
"temp-overheat" : "95",
"temp-cutoff" : "99",
"temp-hysteresis" : "3",
"worksize" : "256",
"lookup-gap" : "0,2",
"thread-concurrency" : "5824,32765"
}
These were my .bat-file srttings for 5850 before I bought the R9 290:
-I 13 -g 1 -w 256 --thread-concurrency 5824
I don't get what I'm doing wrong.
There's obviously more parameters in the .conf-file, but I don't know what to change.
with sgminer using the following script:
