Nvidia cripples cryptocurrency mining on RTX 3080 and 3070 cards
It's likely that this is just a firmware change to the cards and nothing onboard/physically changed at all. If this is the case, then this is hilariously easily defeated by using the firmware updating tool, provided by Nvidia, to get around this. We'll see though. With any luck, they did make physical changes to prevent firmware flashing around this, but I strongly doubt it.
