NVIDIA RTX LHR Unlocker Tool Claims to Remove Mining Hashrate Limit from Ampere Cards

Recently, NVIDIA released the RTX2000 series of GPUs that were designed to be more powerful and efficient than previous cards while still reducing power consumption. Unfortunately for gamers around the world who had pre-ordered these cards, their dream was quickly dashed when they found out that getting these new graphics processors to work as advertised would require them to remove a hashrate limit on every card purchased by using an unlocker tool.

The “how to bypass lhr cards” is a tool that claims to remove the hashrate limit from NVIDIA RTX LHR cards. The tool was released by NVIDIA itself, and it’s not an official release.

SergeyDev, a GitHub user, is working on a solution that would allegedly overcome NVIDIA’s hashrate cap, restoring full mining functionality to the company’s GeForce RTX 30 Series and RTX workstation Ampere-based graphics cards. Although anyone interested in trying out the tool when it launches on February 26 should proceed with caution, SergeyDev has indicated 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 utility, known as the NVIDIA RTX LHR v2 Unlocker, alters the graphics card’s BIOS and needs special graphics drivers, which are loaded automatically with the software.

NvidiaRTX-LHRv2Unlocker is a program that unlocks NvidiaRTX-LHRv2 graphics cards (GitHub)

The first completely automated LHR v2 lock BIOS modifier for RTX cards. It’s easy to use, straightforward, and doesn’t need any prior expertise.
It allows for the editing of previously read BIOS files (using HiveOs or another mining OS) as well as the reading of the BIOS from the graphics card installed in the system, followed by automated backup, file modification, and flash memory utilizing the changed BIOS.
It also improves the performance of RTX Axxxx series cards by modifying their files. There are currently no plans to integrate with more contemporary Nvidia graphics cards.
Release date: February 26, 2022 This is the Early Access/Public Betatest version.

Requirements

To completely hashrate your graphics card, you’ll need to change the BIOS. You’ll also need graphics drivers that I’ve tweaked. When the software is installed, they are immediately downloaded and installed in Windows. If you’re using a different operating system, such as HiveOs, you’ll need to manually install the drivers following the instructions in the DRIVER INSTALATION.txt file in the program installation folder.
I put the driver file on a private server due to its size.
