Hey, I mine ERGO with a MSI 3060 Ti LHR with Hynix, too. My Problem under NBMiner is, that the card will just throw between 77 and 80 MH/s. Directly after startup it does 155 MH/s
, one minute later 124 MH/s and again one minute later it’s with 77 MH/s (look screenshots). 
After nearly 15 minutes (!) the 3060 Ti goes at ~138 MH/s
which is nearly perfect for this configuration. In my second rig are one 2070, one 3070 Non-LHR and two other 3060 Ti LHR which don’t have these problems…

…and again one minute later at 08:18 AM:
Finally at 08:29 AM it reaches suddenly its normal setting:




Maybe the MSI cards have to drive warm before unfolding the full power…
