I'm having the same issue. Whatever card I specify doesn't show a hashrate, and when it eventually does, it's like 30 h/sec and then the miner freezes.
When I do G=0,1,2,3,4 - 3 doesn't work
When i do G=0,1,2,4,3 - 4 doesn't work
When i do G=1, 2, 3, 0, 4, - 0 doesn't work
Thoughts/help anyone?
Just a work-around, but what happens when you run multiple instances with 0,1,2 on one and 3,4 on the other?
