Topic: sgminer, vertminer software crashs (Read 430 times)

Hey guys have a 6 card rig.
MB:Asrock H81 pro
Cards: 6x r9 280x (one asus dc2t, one msi tf, 4 xfx tbdb)
psu: 1475w thermaltake and seasonic 1250w both gold
powered riser used and connected to the 1475w

Had problem with the sixth card deleted the driver in device manager and windows reinstalled the driver naming all cards as 7900 series and in MSIAfterburn all cards are working.

BUT my problem is with the mining software that used to work, now the software crashes and sometimes it tells me that catalyst has crashed.

What to do? any help?

Thank you

UPDATE: more info of current settings
gpu settings are at default, using sgminer 4.1.0 and this is the config:
"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"kernel" : "ckolivas",
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"shaders" : "2048",
"gpu-fan" : "0-0",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "92",
"temp-overheat" : "85",
"temp-target" : "75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-threads" : "2",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"

UPDATE2: installed driver 14.4 where it turned the naming back to 200 series and gave an exclamation point for the 6th card (not detected). Sgminer and vertminer WORK FINE. so it has to do with getting the 6th card activated.
