i have a 5 rx580 rig that is only mining eth at 100MH/s while other ethash coins mine at full capacity of 148 MH/s
I have tried multiple different pools and miners and get the same results.
Anyone else experience this?
You card is probably way overclocked for ETH mining , try to underclock/undervolt your gpu , undervolt your memory , play with power limit ...
If you are using claymores miner , try to set -dcri value in the bat file , start from 30 and keep going lower ... it might help
Also are you dual mining anything with ETH ?
