I’m quite happy with my OC settings and am sharing in case it helps someone else. I had a hard time finding good suggestions for the brand of cards I have. Maybe my search skill stink.
All running stock bios. I did update the 3080 bios to most current and that gave me about 1.5Mh/s more. 3060s running bios out of the box, no updates last I looked.
MSI 3060ti
ASUS 3060ti
eVGA 3080
