I have 4G of Ram, lowering --thread-concurrency to around 12000 will work, but then i cannot go over I 13 or I will get HW error, all in all the best i could make it go was about 150 kh/s and that seems low for a 7950
Try tc 8192, look-up gap 0 and shaders 1792
That helped thanks! doing around 275 Kh/s with
-I 13 -w 256 --thread-concurrency 8192 -g 1 --lookup-gap 0 --shaders 1792 --gpu-engine 1100 --gpu-memclock 1500 --gpu-powertune 20
Running now running with --gpu-engine 850 and Vcc 1.068 for 202 Kh/s, previously 140-150 Kh/s
Happy that i could help you
