hello dok,
since ver 1.7.4 the hashrate on heavy/haven/bittube are broken again. my rx 470/480/570/580 only get 86x, while on version 1.7.3 they can get 11xx.
is there any new config should be added?
Thanks&Regards,
Hin
Don't use old config files.
I have all those cards and they are all hashing the same or better than on 1.7.3. Blockchain driver or 18.5.1, 18.5.2, 18.6.1 all work same good.
Others can also clarify this.
So i guess it's something in your setup, but i can't know what.
Use worksize 8 and dont use fragments 0 , use fragments 1.
It's the same for me. Best config for 4gb is double threads true and I 27, which gives 860. Higher intensity crashes miner in double threads, in single thread intensity is 57, but 740h/s.
8gb cards are giving 1150.
