Only ETH mode gives 32.8 Mh/s for overclocked R9 390X.
ETH + DCR mode gives 30.1 Mh/s ETH + 440 Mh/s DCR for the same graphic card.
As I see in your readme file, I will get higher hashrate if I use dual mode. But it s not. Is it possible ?
Reduce your -dcri to 1 for claymore's miner ( for 440MH in DCR it must be around 30 currently) and you will see your cards max ETH hash rate which should be around 34 Mh/s. Then increase dcri steadily till you start losing ETH hash rate, find the optimum balance point where you get almost your max ETH hash but also significant DCR. This point should be between -dcri 16 to 24.
I did it the way you told.
Only ETH mode gives 32.8 Mh/s for overclocked R9 390X.
ETH 32.1 Mh/s - DCR 16.1Mh/s (-dcoin dcr -dcri 1)
