To dual mine Ethereum you will need claymore client and you can use Nanopool . At Nanoopool they will give you the config file all you need is to enter you address .
Or you can simply use nicehash client and leave it to them they will choose the best options for all your rig including CPU and pay you with BTC directly .
- As for CPU I have no idea .
Thanks ..Actually i have started doing this before reading your post
Claymore+nanopool.Getting around 19Megahashes .. Managed to get 0.00072030 ETH within around 3 hours
They only payout when 0.2 ETH is reached... Don't know if this is will be profitable.
