RTX 3060 LHR mining

RTX 3060 Etchash (ETC) Mining Overclocks:

if the DEVICE ID field starts with the string “10DE 2504 …” then the card is an RTX 3060 produced after May 2021 and therefore LHR.

Core clock really doesn’t affect hashrate at all . If anything, it actually makes it worse if it’s higher, as it’ll force the graphics card to pull more power to the board, and that creates more heat. This doesn’t mean to completely lower your core clock to 0, but a couple hundred down should be plenty.
