You aren't getting the OC right friend, your RTX 3060 should be doing 50MH
I have a rig of ten RTX 3060's. 50 Mh is unrealistic except for the top 1% of golden samples. Most of my cards are only stable at a +1000 Mhz memory clock, which comes out to 46-47 Mh.
Ha, what type of 3060s you have because I am getting 49-50MH on mine, here is my settings
