3080ti LHR.

I have been mining with a RTX 3080ti for a little bit and messing with settings to increase hashrate a bit. I’m using hiveos and wondering what may be resetting my uptime. When I was using the top cardinality, I was hashing 82-85mh/s, and stayed up for a few days. Changed setttings and get 85-87mh/s but it resets miner every day in half. It moves up and down from 280w-my PL of 300w. What can be resetting my uptime? Is it normal to have it fluctuate consistently? Does it matter if it resets every couple of days?I have 1660ti that don’t move at all. New to mining thank you.
