The NVIDIA RTX 30 series has been upgraded to the LHR version, locking the ethereum mining card at about half of the level, but there have been cases of official driver accidental cracking of computing power earlier, and now players have found new vulnerabilities.
According to foreign netizens @bravo_char study found that most of the RTX 3080 Ti LHR default BIOS settings are hidden in a power consumption restriction, once the video memory load is found to be too high, it will be considered to be mining, and then start this restriction.
Theoretically, conventional methods can't bypass it, but it's interesting to note that EVGA found out about the problem and thought it was a bug, so it released a firmware patch.
As a result, after updating the firmware, the Ethereum hash rate of the EVGA RTX 3080 Ti has increased from 66MH/s to 80MH/s, an increase of 21%.
Other brands of RTX 3080 Ti naturally do not have this official treatment, but @bravo_char to take a piece of Yingzhong RTX 3080 Ti iChill X3 Super Ice Dragon Edition to try, but also brushed into evagaved firmware, the result was actually successful, and the computing power was unlocked to 91MH/s, an increase of 38%!
Of course, cross-brand firmware brushing is extremely dangerous for graphics cards and is generally not recommended.
