Msi rx580 gaming x 4g bios help

I bios modded my two msi rx580 gaming x 4g versions coping 1500 strip to 1625,1750,2000,1500,1625,1750, and 2000 strips. Cards are running fine after doing so they both went from about 270 h/s to 300 h/s. Want to know what msi afterburner setting people are using to better that and run more efficient tried changing couple times but keep crashing. What are you guys running on these cards. I donโ€™t want cards running to hot or dangerous if this max let me know thanks for help!!:+1:t3::+1:t3:
