Anyway, I figured something out, just run one of the Rx cards with the R9 cards and it works like it's supposed to.
Nice that you found a workaround. Once you have configured your rig correctly the miner is stable for weeks.
Hey sp_,
i tried your miner with one of my igpu, but it won´t connect to pool if i mining to zergpool. On f2pool it sometimes work after 1 or 2 restarts via loop.
With verthashminer it works without any problems.
