Thanks for your help

With your settings I get an error

Error -4 enqueueing kernel onto command queue GPU 0 failure

Strange all errors regard only the r9 290, hd 5770 runs well

I got my 290s running at 350 with wu 310 and 325 running multiple instances of vertminer 0.5.3

This is my sapphire reference 290

Code:

{
"pools" : [
{
"url" : "stratum+tcp://east1.us.stratum.dedicatedpool.com:3379",
"user" : "xxxx",
"pass" : "xxxx"
}
]
,
"device" : "1",
"intensity" : "13",
"worksize" : "256",
"lookup-gap" : "2",
"gpu-engine" : "947",
"gpu-memclock" : "1250",
"shaders" : "2560",
"scrypt-vert" : true,
"thread-concurrency" : "10241",
"expiry" : "30",
"gpu-threads" : "1",
"gpu-powertune" : "20",
"scan-time" : "1"
}

#And this is my 290 Tri-X

Code:

"pools" : [
{
"url" : "stratum+tcp://east1.us.stratum.dedicatedpool.com:3379",
"user" : "xxxx",
"pass" : "xxxx"
}
]
,
"device" : "2",
"intensity" : "13",
"worksize" : "256",
"lookup-gap" : "2",
"gpu-engine" : "1020",
"gpu-memclock" : "1250",
"shaders" : "2560",
"scrypt-vert" : true,
"thread-concurrency" : "10241",
"expiry" : "30",
"gpu-threads" : "2",
"gpu-powertune" : "20",
"scan-time" : "1"
}

They're running at 68c & 65c with no rejects and no HW errors. If I can improve performance without pushing them too hard would be great, advice welcome.
