It is unclear how NiceHash managed to eliminate the mining rate limits. Previously, developers created software that recovered 68 percent of the hashrate of the video cards in question, while NiceHash recovers the entire 100 percent. 

NiceHash provides a screenshot of a QuickMiner installation that employs 100 percent of an RTX 3080 Ti, resulting in a hashrate of 120.12MH/s. Benchmark.pl backs this up with their own tests. The first NVIDIA LHR algorithm was mistakenly unlocked by NVIDIA after non-LHR drivers were released prior to the introduction of an improved LHR algorithm with the RTX 3060, which is currently featured on all RTX 30 cards except the RTX 3090. Before releasing this complete unlock, the NiceHash developers had previously revealed an unlock mechanism to reach 70% mining performance by August 2021. A Benchmark team independently verified this unlock, recording hash rates of 117 MH/s with the RTX 3080 Ti, up from 85 - 88 MH/s previously.

We are very excited to tell you that NiceHash QuickMiner (Excavator) is the first mining software to FULLY (100%) UNLOCK LHR cards!

Now you can earn more profits than any other mining software on the market if you are using LHR graphics cards with NiceHash QuickMiner. Support for NiceHash Miner is coming soon.

NiceHash has a bypass around Lite Hash Rate throttling on nearly all RTX 30 graphics cards.
