Add -t 3 in the line of ethermine.exe And for the best hashing, I recomende use a PROXY version 0.0.5 Regards. Antuam Title: Re: ethminer multi gpu setup Post by: Za1n on March 19, 2016, 09:56:29 AM Just to keep things simple to start, this line should be all you need:
Code: ethminer.exe --farm-recheck 200 -F -G http://eth-eu.dwarfpool.com:80/address/Worker1 You can add any additional parameters once you get the basic setup running. Did you check Device Manager to see if all 3 GPUs are showing up? It should look like the image below, but with 3 just gpu's showing: https://i.imgur.com/JiY4jti.jpg?1 Title: Re: ethminer multi gpu setup Post by: juni0r on March 22, 2016, 01:18:21 PM Just to keep things simple to start, this line should be all you need: What is the amount of hash rate you are getting with 4 x R7 ?Code: ethminer.exe --farm-recheck 200 -F -G http://eth-eu.dwarfpool.com:80/address/Worker1 You can add any additional parameters once you get the basic setup running.

did you manage to solve this issue? i have the same issue. i have 2X MSI R9 280X cards and one is giving me around 18MH while is should give me more and the second is giving me an additional 4MH so either i am doing something wrong or the pool isnt showing the right MH (i am using nanopool). which pool is recommended? i tried to work with the proxy but it the ethminer isnt connection for some reason. |
