Does this applies to all 3060 cards including old and new? are they all restricted either by driver or by firmware ?
The earliest versions of the GeForce RTX 3060 mined Ethereum very poorly. Then, when using 16x raisers or installing video cards into 16x ports on the motherboard (which support more than 8x operation mode) and a special driver, it turned out to mine with a hash rate of 48 megahash.
For subsequent versions 1 and 2, the hash rate cannot be increased more than 40 megahash.
