Yiasou!!!
Take look on YouTube how to flash bios. I like this video… How To Flash Nvidia RTX 3080 Trio BIOS To Asus Strix for a higher Hashrate or better FPS - YouTube
Then download and use the ASUS Strix bios. Check the version on the video and download the same. Its the version from 2020 - not 2021. Make sure you follow the flashing instructions exactly. Reboot into HiveOs and you will see the card as ASUS not as MSI. Set clocks to… absolute core 1070, memory 2500, fan 70% - you will get 100.5MHs on ETH.
Goodluck!
