Rejected Shares/OC

Hoping someone can help me out, I have been mining ravencoin for about a month but no matter what setting I use I continue to get rejected Shares

I have 4 3060s, 1 2080ti, and a 1070.

I have gotten the 1070 stable but continue to get rejected Shares no matter what I try. Although small percentage of rejected still very annoying. Can you guys share your settings
