Can anyone share hashrates you get on qubit on 7850 GPUs with sph-sgminer? I can't max out 1.4mh for 7850 (on Ubuntu), but reading the thread I've got impression it should be at least 2mh for 7850?
it would depend on the coin you are mining
i get 1.9mh/s with a 6850 at --gpu-engine 950 --gpu-memclock 1150 -I 16 on qubit algo
and 930kh/s with --gpu-engine 900 --gpu-memclock 1000 -I 16 -g 2 -w 256 on dark
