I have one righ with 4 x RX 470 . Problem is that 3 card works but 4th wont work whatever setting I try . It gives 0 hash power. Do you have any solutions for this?
I tried on other rig with 6 x RX 470 same problem.
either your work batch is too high, or your virtual memory too low
Same problem here on one rig with 6x RX 470.
I've set working batch on AUTO, but the problem still occurs and shows 0 MH/s on Device 2 (card on the main slot.)
Also, have the same problem with other mining software so I guess I should better reinstall Win 10.
