Hi I have 3x SAPPHIRE TRI-X R9 290 4GB GDDR5 OC(UEFI) with Win 8.1 , latest cata drivers 14.4 and latest sgminer 4.1.271. Can I use this conf from above ?
"gpu-threads" : "1",
"xintensity" : "1100",
"thread-concurrency" : "25601",
"worksize" : "512",
"lookup-gap" : "2",
"gpu-fan" : "80",
"gpu-powertune" : "20",
"gpu-memclock" : "1499,1499,1499",
"gpu-engine" : "1080,1080,1070"
You will need to figure out the maximum gpu-engine settings for each GPU. You can start at 1080 if you want, and then every time a card goes SICK/DEAD, edit your config and drop the clock by 10mhz, and reboot the rig.
1080 engine is rather high, and many cards won't be able to run at this setting.
