I see some peoples get about 165 sols/s +- using genoil miner with driver 16.10.3
but the card should be [8GB] ( he test with RX 470 ).
kernel : zec-sa.cl
comand :
genoil.exe -k zec zec zec zec -c zec.suprnova.cc:2142 -u user.x1222 -p xnxx -i 20 -w 64 -P 0 -f 2 -z 0
give it try!
it works great but no updates that's the problem it has major crashes etc but it does work and good if you can deal with the bugs it has .
