That tool that was supposed to unlock the full hash rate of Nvidia LHR cards is actually malware
It turns out that miners looking to extract the maximum hash rates from Nvidia’s Lite Hash Rate RTX 30 series cards have been fooled. The tool does not remove the hash rate limiter, but instead installs malware.
As we reported just yesterday, it appeared as though an enterprising modder had managed to completely bypass the crypto mining restrictions Nvidia places on several of its RTX 30 series graphics cards. The user, ‘Sergey’ released a BIOS modification tool on GitHub that supposedly bypassed the checks that Nvidia has in place to lower mining performance when Ethash mining is detected.
If a user downloaded and ran the ‘LHRUnlocker Install.msi’, it simply didn’t do what it claimed to do, instead infecting powershell.exe, which is a Windows service with malware. It’s also unknown what impact the malware has. Speculation includes everything from keylogging to attempting to set up a botnet for mining.
Several users proceeded to post questions Sergey’s own GitHub page which went unasnswered. The page has since been taken down.

The exposure of this tool as malware means that Nvidia’s LHR limiter remains intact. While legitimate (in a vague sense of the word) methods have managed to bypass the limiter to some extent, LHR cards still cannot match the Ethash rate of their FHR counterparts. Nvidia deserves credit for at least attempting to reduce the appeal of many of its gaming GPUs to miners.
So, if you’re downloaded the tool and you’re waiting for that ‘special driver’, please delete anything and everything from this scammer. It serves as a reminder that crypto remains in the equivalent of the wild west days. A general rule , if it’s too good to be true, it is.
