Having problems here .....5x8x1080TIs (EVGA SC2), five identical rigs on Windows 10. (65,-100,650) They run great for 7-10 hours at 50MHz +/- and then the rigs disconnect from ethermine and cannot reconnect until everything is shut down and restarted.  Has anyone else run into this?  Using ethminer-0.15.0.dev4. 

Currently lowering clocks to no avail as of yet.  It's driving me nuts.
