I'm using the latest driver for 6 pieces of GTX 1070 in 7/24 with no problems: 180 MH/s.
can you share your settings? i have 5 1060 and it locks up after 20 min of use and i need to reboot the system. i can only pin it on the miner.

GPU & other settings were posted just a few lines above, also you can read my blog for all the details:
