About low hashrates in dual mode - it seems I need to combine some of my messages into one and add some more comments about ETH+LBC mode.
1. AMD cards always handle dual mode better than NVidia. Especially 290(X)/390(X) cards, they are the best. RX480 is good too. Other cards are not so good in dual mode.
2. Lbry is not so good for dual mode as Sia or Decred, it takes too much GPU time, therefore ETH suffers. So only powerful cards are good in ETH+LBC mode. Do not use it on 280, 270, 7xxx, etc. On these cards ETH+DCR or ETH+SIA is better.
3. My test rig: 6x390, stock clocks, gives 172MH/s ETH in ETH-only mode.
In ETH+LBC mode, "-dcri 16", it gives 167MH/s ETH + 167MH/s LBC.
Dear Claymore,
Would it be possible to implement monero (CryptoNote) into the dualminer as well? I know, that you already have made another xmr miner, but to have such a profitable coin implemented would be really good. What do you think about it?
Actually, I am using your linux 7.0 build running on my amd rigs configured to mine eth+lbc. And for 5 x R9 NANO the results: ETH 120MH/s + LBC 200MH/s.
as per my understanding.... ETH and XMR are both using memory intensive algorithms (Ethash and Cryptonight) - so ETH + XMR maybe a bad idea. However XMR + DCR/SIA/LBRY combo like CDM is more realistic. In the XMR thread, Claymore already said that there is no plans for 2nd coin for XMR.
