Miner is compiled with 15.12 drivers, but for Polaris cards you cannot use 15.x drivers, so use 16.x drivers, currently I use 16.11.3 for tests.
If you don't overclock your cards, check PSU and risers.
through line the red line .. Agree - many only a problem from the new miner. And normal driver 16.11.5
Make at least once not a beta version!
