Hi mate, your core OC is too high, and 530 sol/s, seem like you run it at 100% power limit, It's a bit too much. For me, I always set power limit at 80% only.
You could test it at stock setting first. Then step-by-step OC with higher core. I mined with P104-100 as well, so far so good, for your interest, please check my tests in following thread. By the way, I think P104-100 could do better on mining ETH rather than mining ZEC.
