Update 2/23: The NVIDIA RTX LHR Unlocker Tool has turned out to be malware, according to tests from YouTubers such as Red Panda Mining, who have demonstrated why it should be avoided at all costs. The GitHub page for the tool has also been removed.

Original story:

A GitHub user by the name SergeyDev is readying a tool that can supposedly bypass NVIDIA’s hashrate limiter and restore the full mining performance of the company’s GeForce RTX 30 Series and RTX workstation Ampere-based graphics cards. Caution is obviously advised for those who are willing to try the tool out when it debuts on February 26, but SergeyDev has teased that it can unlock hashrates of up to 100 MH/s and 115 MH/s for the GeForce RTX 3080 (LHR) and GeForce RTX 3080 Ti, respectively. The NVIDIA RTX LHR v2 Unlocker, as the tool is called, modifies the BIOS of the graphics card and requires special graphics drivers, which are installed automatically alongside the program.

NvidiaRTX-LHRv2Unlocker (GitHub)

  • The first fully automated BIOS modifier for RTX cards with LHR v2 lock. Using it is simple, intuitive and requires no advanced knowledge.
  • It enables the modification of previously read BIOS files (using HiveOs or other mining OS) and reading the BIOS from the graphics card installed in the system, then automatic backup, file modification and flash memory using the modified BIOS.
  • In addition, it also modifies files in RTX Axxxx series cards, increasing their performance. At the moment, no integration with more modern Nvidia graphics cards is planned.
  • Planned release: 02/26/2022 this will be the Early Access version / Public Betatest.

Requirements

  • Modifying the BIOS is not enough to fully hashrate your graphics card. You also need graphics drivers modified by me. They are downloaded and installed automatically in Windows when the program is installed. If you are using another OS such as HiveOs etc. then you need to install the drivers manually according to the instructions found in the DRIVER_INSTALATION.txt file in the application installation folder.
  • Due to the size, I placed the driver file on a private server.
