Nvidia’s crypto mining limiter has just been fully cracked

Must read

The Lite Hash Rate (LHR) algorithm, which limits the crypto mining of certain Nvidia RTX 30 graphics cards, has been completely cracked.

NiceHash has confirmed that they have developed a solution that allows you to mine the Ethereum currency on GPUs without any of the restrictions imposed by Nvidia.

How reported by Tom’s Hardware, NiceHash is the company behind the QuickMiner and Excavator mining software. Other individuals and groups have naturally tried to avoid the LHR cap on Nvidia GPUs with their own software. For example, Tom’s Hardware points to one called NBMiner, which was able to unlock up to 70% yield.

However, an application that offered 100% ETH crypto mining capabilities has yet to be implemented. So far.

Tom’s Hardware said they tested the latest QuickMiner version of NiceHash, and confirmed that it does unlock 100% Ethereum mining performance for several Nvidia RTX 30 series video cards.

Currently, QuickMiner provides support for the DaggerHashimoto (Ethash) algorithm, which is said to be compatible with almost all Ampere-based Nvidia GPUs. However, you will not be able to get 100% performance from both the GeForce RTX 3050 and GeForce RTX 3080 12GB. Tom’s Hardware attributes this special restriction to the reported implementation of an updated LHR algorithm (LHRv3) for both of these tables.

In any case, Tom’s Hardware tested the program on the GeForce RTX 3080 Ti Founders Edition and found it to “quickly” exceed 100 megabytes per second (MH / s). By comparison, the website said the LHR limit, which was previously in place, would deliver a maximum of 77 MH / s.

Theoretically, NiceHash thinks that crypto enthusiasts could push the GeForce RTX 3080 Ti LHR rate to around 120 MH / s, though that would require applying huge overclocks – this could potentially prove to be unstable and dangerous if you don’t know the process.

The sample of the site was a Founders Edition version of the GPU, and it emphasized that turning the GDDR6X memory to 110 degrees Celsius was of course not a scenario it wanted to distract.

However, using QuickMiner’s “Medium” optimization setting, it was able to extract “constant hash rates from about 108 to 110 MH / s – still at 108 degrees Celsius on the GDDR6X, by the way.”

Earlier, someone released a tool that claimed to go beyond mining limits on Nvidia GPUs, but that immediately proved to be software that spreads malware.

Meanwhile, LAPSUS $, the group behind Nvidia’s 1TB hack, has stated that it has managed to locate the algorithm responsible for LHR restrictions. However, it sold the tool for $ 1 million. Let’s hope no one accepted them on that offer.

Will this have any effect on the GPU market?

Given the fact that the GPU industry has begun to recover, consumers may be wondering if the software will have a detrimental effect on the market – will there be another shortcoming? Will prices start to rise?

The short answer? Not really.

Tom’s Hardware stands out as a profit, at current rates for Ethereum, on a powerful card like the 3080 Ti would only generate around $ 3.50 a day. As a result, a crypto-miner would need almost a year to simply level up and only recover the cost of the GPU itself.

While the appetite for crypto mining remains strong, those who make significant profits from space are for the most part limited to groups or mining estates which can pay for hundreds of Nvidia GPUs and the related power bills that come with running such platforms.

However, these groups will have to take a huge risk if they decide to invest in these Nvidia GPUs due to the threatening prospect of the Proof of Stake (PoS) concept, which would disable the ability to mine ETH on graphics cards. Whether PoS will be realized in the near future is a completely different discussion.
