I would say that since the card is a MSI it is a good value for that hashrate.I personally own 2 MSI cards,one 3060 ti which can't do more than 59.9 Mhsh and a RTX 2060 12 GB which can't stay stable at 37 Mhsh but only at 36.4 Mhsh.I have one of such cards with Samsung memory so I blame the brand and not the memory chip (Samsung,Hynix,Elpida or Micron),it looks to me that MSI cards do not support really high overclocks and it appears so,also in my old cards 1050 ti and 1060 the same was happening with MSI cards,that is why I came to this conclusion.
I have MSI 3060ti that do 61MH on hive OS, what is your OC settings and also what is the memory of your GPU? Samsung, hynix or Micron? To achieve the outmost hashrate you need to use different OC settings.It is a Ventus MSI 3060 ti with 2 fans.I am even using even lower than correct overclock settings,the correct ones are power limit 60%,core clock -200 and memory clock +1200 Windows/2400 Linux.I have the memory clock at +999 and it still gets a lot of incorrect shares because of that overclock of which it does not support.My memory is samsung as you can see in the picture below:
