Frequently Asked Questions
Is GPU mining still profitable in 2023?
Yes, though with reduced margins compared to 2021 peaks. Careful cost analysis is essential.
What temperature is too high for mining GPUs?
Consistent operation above 80°C may shorten component lifespan. Target below 75°C.
How many GPUs can one motherboard support?
Most mining boards support 6-8 GPUs with proper power distribution.
Should I buy LHR (Lite Hash Rate) cards?
For Ethereum mining, non-LHR remains preferable. Post-ETH mining, LHR limitations become irrelevant.
