I started mining with two RX 570s, modded the BIOS and overclocked. Getting 27 MH/s per card on ethereum only which is pretty good i think. I'm running Win 10, with the new AMD Blockchain Compute drivers, and the newest claymore dual miner.
So i wanted to try dual mining because i see almost everyone reporting higher profits, plus i don't pay for electricity so its even better. The problem is that i can't get any profitable results! I tried DCR, SIA and LBRY with a range of -dcri settings form 5 to 50 and no luck. For example if i mine ETH+SIA with dcri set to 5 i drop from 54 MH/s to 50 MH/s ETH and get 252 MH/s SIA. Set dcri to 10, and i get 45 eth and 450 sia. If i set dcri to 3 i get a 2MH/s drop on eth but i get almost no hashrate on secondary coins...
I've read a lot of reports of people setting dcri to 20-30 and getting no or very little drop on ETH and a nice profit from SIA(or other coins).
Any idea what could be wrong? Maybe i should try with older drivers?
