The only changes in my run line are -
--cl-local-work 256 --farm-recheck 200
how do you get 34MH with your 390x i only get 28MH
might it be windows that does it. useing latest driver 16.2 and ethminer-0.9.41-genoil-1.0.4b3
have a Saphire 390x core 1080
I'm using Ubuntu 15.10 and the latest Crimson drivers (see my build notes in previous post)
Overclocked the XFX card with -
aticonfig --adapter=0 --od-setclocks=1160,1675
The card will go faster, but, I don't wanna temp it above 75c - fans too noisey
Windows has always been shit for mining, IMHO.
The code is ALWAYS a port that abstracts system functions and something is most always lost.
Show me one coin that mines faster on Windows and I might switch, but I doubt it.
