- Why Ethereum hashrate in Dual mode is higher than in Single mode?
Hardware feature, accept it as an extra bonus.Magic hardware!

I've dual mined ETH with both Siacoin and Decred at several settings (from 20 to 80%), and at all settings my ETH takes a hit. In a 7 card GTX 1070 rig the ETH hashrate drops from ~220 MH/s to 210, 200, 180, even 155.
Anyone here able to mine ETH (with another coin) and NOT take a hit --- let alone have the rate increase?
THANKS
