Power Issue: then tell us PSUs that you are using
OverClock - Under Volt: then tell us your current OC-UV settings.
And so on..

WATCHDOG: GPU 5 hangs in OpenCL call, exit
It showed that you've set (-minspeed), when your rig doesn't reach that specified amount of speed, the miner will restart nor call (-r) parameter (if -r set to "1") it will re-starting Claymore.
Try to bring back your cards setting (troubled card) to default may help.
Will be better to visit Claymore official thread for the best result related to your problem!
