And strange bug with these 17.2.2 drivers. On all versions GGS from 1.1.8 to 1.1.12 after start mining and stopping after, 1st GPU (monitor connected) continue to show 100% activity. Core clock is maximum, memory clock at 300. Temperature is low, but a bit higher than at 300/300, fan drop to low or 0%. All functions work. Miners starting on it and works at 97-99% speed on this GPU. Computer hangs during rebooting. And not rebooting until power off and on.

Had the same bug, I found this was caused by not very heavy overclocking. Try pls lower your GPU Clock by 10+ and do so with your Mem clk as well. You can seek your sweet point, try and seek. Tryed at Neoscrypt only, the others algo nowadays aren't worth of talking with AMD cards.
As was said before by Zawawa, U will need to check and find, bcause THIS miner is completely different from others. This will be the answer to your coldboots and 100% loading of one of your cards when mining tread hungs.

I tried to increase GPU voltage, it's helps on neoscrypt for sometime. Thread hangs not so quick, but on cryptonight it didn't helps at all. I use lowered clocks for my 580 cards. I use 1245MHz GPU clock. Lowering it decreases speed - and this is not good for me.
I think it's drivers bugs, on 17.11.4 all was right.
