I get with lolminer only 0.31 Mh/s when I use to get 12 Mh/s
What to do to increase this back to 12 Mh/s.
I have run mine_eth_4G.bat
Why are you still using Windows? Everyone has already migrated to Linux-based mining OS-es.
I know that but still if I get before out 12 MH/s why I can't get the same now?
With each new ETH epoch, DAG file size increases, which makes 4GB more and more inefficient. What lolminer does, is cheating and postponing little bit the inevitable.
