Hi guys. I have my 6 gpu rig for 3 months now and I have to say that I was lucky not to have any problems,overclocking works,undervolting work,had to replace a riser 2 weeks ago but nothing else so thats Smos for beeing Simple:). I want to try dual mining to see what's what but from my initial speed of 166Mh/s on ether, I now get 100mh/s eth and 3220mh/s siacoin. I ve read 100 pages back and on Claymores Dual Mining thread and I know I should ad a "-ethi" and "-dcri" somewhere.
I am using this:

 -epool eu1.nanopool.org:9999 -ewal YOUR_ETH_WALLET/YOUR_WORKER/YOUR_EMAIL -epsw x -dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal YOUR_SIA_WALLET/YOUR_WORKER/YOUR_EMAIL -dcoin sia
     I get 100 on eth and 3220 on sia

If I try:

 -epool eu1.nanopool.org:9999 -ewal YOUR_ETH_WALLET/YOUR_WORKER/YOUR_EMAIL -epsw x -dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal YOUR_SIA_WALLET/YOUR_WORKER/YOUR_EMAIL -dcoin sia -dcri 2
     I get 160 on eth and 160 on sia

Happy for some help:). Thanks
