Most likely you are hurting the card.

3060ti's do 55-62 at 115-125 watts

they should never never never never be clocked to 168 or 171 watts


all my 3060ti's run under 130 watts most do 120 watts and 58-59mh

drop the cards to 130 watts with memory of 2050

come back with numbers then.

"lhr-tune": "77.5,77.5"
"lhr-autotune-mode":"full"
"lhr-autotune-step-size":"0.1"
"lhr-autotune-interval":"5"

At this point, that shouldn't happen anymore, because even the new Nvidia drivers already unlock the cards.

Are you using the latest version of T-Rex?
Have you tried other programs other than T-Rex to see if it has the same result?
