NiceHash officially cracked Nvidia's LHR limiter 

Last year we signed the Pact for Gender Equality in Colombia, an agreement that symbolizes the co-responsibility of around XNUMX organizations with the implementation of actions that contribute to reducing inequalities. Nvidia in response to high demand in the graphics card market on the part of the miners, decided to restrict their graphics cards RTX 3000 to make them less attractive, leading many miners to go for other alternatives due to reduced mining performance.

In response to the new limiter, several crypto companies started working on a workaround. In the past, there have already been reports of ways to restore at least some of the mining performance and apparently, the Nicehash company managed to unlock all the mining performance for the first time.

More than a year after the introduction of LHR graphics cards, now you can harness the full potential of NVIDIA RTX 30xx GPUs, this thanks to an announcement made by NiceHash developers.

The LHR graphics cards were meant to reduce performance for Ethereum and other alternative GPU cryptocurrencies by up to 50%. Interestingly, the NVIDIA LHR algorithm was first unlocked following an incident involving NVIDIA itself, after the company accidentally released non-LHR driver code. NVIDIA quickly fixed the LHR algorithm and released a second version of its RTX 3060 GPU. Since then, all RTX 30 cards have switched to LHR variants except for the RTX 3090 series.

NiceHash developers were among the first to unlock 70% of the LHR algorithm. This goal was achieved in August last year. Therefore, it took another 9 months to discover the LHR lockout mechanism and disable it for most SKUs. Today, the software 100% unlocks all RTX 30 cards with LHR, except for the RTX 3050 and RTX 3080 12GB, which may feature a new type of LHR algorithm that has yet to be cracked.

The new LHR unlock only works on Windows and is only compatible with the algorithm DaggerHashimoto (Etash).

For the moment, only NiceHash Quickminer supports unlocking from secretive companies, but several high-profile miners, such as YouTube's Son of a Tech, have posted videos showing that the software lives up to its claims.

In a blog post, NiceHash confirmed the situation:

“We are pleased to inform you that NiceHash QuickMiner (Excavator) is the first mining software that FULLY UNLOCKS (100%) LHR cards! Now you can make more profit than any other mining software on the market if you use LHR graphics cards with NiceHash QuickMiner. NiceHash Miner support is coming soon. This also makes it more advantageous than directly mining a pool, as other software cannot unleash the full capacity of your hardware. Sign up for NiceHash, download our QuickMiner and get paid in Bitcoin every 4 hours! »

QuickMiner is a one-click miner designed for ease of use with a gaming mode for gamers and automatic overclocking (OCTune). Use Excavator (now with 100% LHR unlock!) to mine Ethereum and XMRig for CPU mining.

In his blog post, NiceHash claims no Linux support yet:

"100% LHR Unlock only works on Windows." But the NBMiner (NebuMiner) team also developed their software that unlocks 100% mining performance on GeForce RTX 30 GPUs on Linux.

Both programs are closed source, so we can't see exactly how the LHR was cracked (that would be very interesting, no doubt).

What is evident here is that two computers running popular encryption tools managed to unlock LHR cards at almost the same time. This begs the question of whether they shared information with each other and how they found the method in the first place.

Anyway, on Twitter, crypto miners have confirmed that the NBMiner v41 software does indeed work, this is the first time LHR has been cracked on Linux.

the news it is a blow to players who have seen a drop in prices of graphics cards in recent weeks, as prices for cryptocurrencies like Bitcoin have fallen and graphics card supplies have improved, with many even retailing for MSRP (Manufacturer's Suggested Retail Price), commonly called list price or list price).

However, with a slowdown in the markets and the price of most cryptocurrencies, as well as rising utility bills, the impact of the news is certainly less than it would have been six months ago.
