For r9 280x, am getting " shares above target" rejects.
Can you help out with the commands?
try this with sgminer!
-I 20 -g 1 -w 256 --shaders 2048 --thread-concurrency 8192 --lookup-gap 2 --gpu-engine 1150 --gpu-memclock 1500 --gpu-powertune 20
Thanks for helping out, but am getting the same rejects.
