optimise mining rig settings on HiveOS, running HiveON

i have a very simple rig with 1 3090 GPU card

currently running HiveOS, using HiveON pool

the rig keeps restarting

mining ethereum

initially showing 118MH/s hashrate for the first 1-2 hours then crashes and restarts

now showing 118MH/s ethash but only 8.33 MH/s hashrate on hiveon

I would like someone to adjust settings so mining at 110+ consistently without crashing etc on hiveon (or another reliable pool)
