Someone please help! When I try to mine with RX480, the miner crashes. A have 3 card - 2x270X and 1xRX480. If i try to mine with only 270X, there is no problem, but if I try to mine with all 3 or just with the polaris - the miner crashes. I post last rows from log file:

I don't know what happened, I was mining with RX480 for 1 day, but then I try some intensity changes and after all I cannot mine with RX480 anymore...
