In order to limit mining, all NVIDIA RTX 30 graphics cards have been upgraded to the LHR version, which is the version that limits the computing power, which can greatly limit the mining efficiency. However, as early as a few months ago, there were cases of official drivers accidentally cracking the hash rate. At present, in order to improve the efficiency of mining, miners are sparing no effort to find graphics card software and hardware vulnerabilities.
A few days ago, foreign netizens found that most of the RTX 3080 Ti LHR default BIOS settings are hidden in a power consumption limit, once the video memory load is found to be too high, it will be considered to be mining, the graphics card will start the power limit.
Interestingly, however, when EVGA discovered this problem, it thought it was a system vulnerability and released a patch. After the fix, the EvGA RTX 3080 Ti's Ethereum hash rate increased from 66MH/s to 80MH/s, an increase of 21%.
In addition, netizens also tested other brands of graphics cards, the model is Yingzhong's RTX 3080 Ti iChill X3 Super Ice Dragon Edition, surprisingly, the graphics card is also brushed into evagabite firmware, and the computing power is unlocked to 91MH/s, an increase of 38%.
Although NVIDIA has been thinking of various ways to limit mining, due to the huge yield, many miners are still frantically hoarding graphics cards, coupled with the lack of chip production capacity this year, resulting in a serious shortage of graphics cards.
