Hi, I've been mining with 7x r9 390 8GB with phoenix miner, but from 2/3 days ago it has started to reboot very often
So I disabled one to test if with only 6 would have the same error, but it mined for half hour and rebooted again

this a print form last crash:

Is this a miner error? Claymore also has this behaviour

teamred doesnt recognize hawaii?
