Already nvidia rtx hash limiter

already nvidia rtx hash limiter

And we also understand that if this is done at a BIOS and driver level, NVIDIA can not revert or limit this on products already sold (incl the legal ramifications they’d face).

When the news broke yesterday, the community’s response was ‘meh …’ average for the reasons listed above. Also, it immediately became fuzzy how NVIDIA would apply a hash rate limit on existing products. I mean, if this is at a driver level, it can be easily hacked.

However, an NVIDIA spokesperson clarified what NVIDIA is doing; he said, “there is a secure handshake between the driver, the RTX 3060 silicon, and the BIOS (firmware) that prevents removal of the hash rate limiter“. And that does make this a more secure solution. However, BIOSes can be altered, drivers as well.


And that’s bad news for gamers.A Vietnamese Facebook group has also verified that this mod actually works and can deliver up to 50 MH/s on the NVIDIA GeForce RTX 3060 graphics card. Such hash rate would mean that Crypto miners will now rush after the GeForce RTX 3060 graphics cards considering they deliver the same hash output as the RTX 3060 Ti and close to the RTX 3070 with a much lower power draw.
Basically, what this all means is that the GeForce RTX 3060 is now a prime target for miners. With cryptocurrency performance no longer nerfed, the card is more attractive than higher-end models.
The unlocked GeForce RTX 3060 delivers close to the hash rate of the GeForce RTX 3070 — with much lower electricity consumption. With GPU supply already struggling massively to keep up with demand, the odds of getting your hands on a decently priced GeForce RTX 3060 just dropped significantly.

At the moment, only one RTX 3060 at a time has been hacked; if a group of them is operating together to mine cryptocurrency, the hash limiter might still be able to do its thing. Guess we’ll find out about that soon enough too but until then, watch this space.

About Nvidia

Nvidia Corporation is a multinational technology company incorporated in Delaware and based in Santa Clara, California.

Known for producing some of the best Graphical Processing Units (GPU) in the market, the company also provides parallel computing solutions to researchers and scientists worldwide.
Not to mention, they also produce mobile computing chipsets in the form of Tegra Mobile Processors.

NVIDIA LHR series

We received an update on the upcoming GAxx2 NVIDIA GPU series featuring a new cryptomining limiter.

NVIDIA has provided an update to its partners in regard to upcoming xx2 chips. Those GPUs will feature a new cryptocurrency mining limiter and most likely RezisableBAR support without a need for a vBIOS update.

NVIDIA is expecting GA1XX-xx2 chips to start shipping in the middle of May, which means that first customers may receive their cards in June.

Our sources have been quite clear that NVIDIA has no plans to differentiate LHR chips from existing models. All cards will feature the same product names and the only way to distinguish LHR from non-LHR chips is by looking at the GPU.

Eventually, graphics card monitoring tools should be able to recognize which version is used.

So we’ll see how that turns out.

In related news, Videocardz yesterday picked up on a story from youtube CryptoLeo, a miner that is active on social. His video demonstrated how incredibly fucked up the market is, as he already has RTX 3060 in his hands and tested!! A retailer has been selling the RTX 3060 cards ahead of launch for 800 USD a piece, that same retailer sold all of the stock to miners already, and the card isn’t even released (!) The products sold …

ZOTAC, which had their you know what handed back to them two days ago, promoting mining on their Twitter account.

Back to CryptoLeo, he tested the RTX 3060 hash rate, and it indeed dropped from 41.5 MH/s to 26-24 MH/s, so these cards are inefficient for miners. Interesting to note is that there is no driver for RTX 3060 yet, so it had to be a hacked driver.

With graphics cards pricing coming down and the end of Ethereum mining on the horizon, many are expecting graphics cards to become affordable once again. Unfortunately, there may be a set back, as a new software can reportedly completely remove the mining hash rate limiter on Nvidia RTX LHR GPUs.

The new software developed by Sergey (via VideoCardz) consists of a tool that replaces the graphics card’s BIOS with a new one on RTX 30 and workstation RTX models with LHR.
Although the software hasn’t been tested yet, Sergey claims the LHR v2 Unlocker can unlock the full mining performance of any LHR card.

LHR v2 Unlocker introduces modifications extracted from BIOSes used by mining OSes on the desired graphics card and a graphics driver modified by the developer.

UPDATE March 11, 2021 – NVIDIA anti-mining technique not hacked yet WCCF Tech has corrected its original article. It appears the anti-Ethereum mining algorithm hasn’t been hacked yet: It seems like the mining algorithm used here wasn’t Ethereum but Octopus which is a different cryptocurrency coin and based on an algorithm that NVIDIA might not have limited its hash rate for yet.

So as of right now, the hash rate limiter remains in place but if other crypto-currencies can give out similar profits as ETH, then that doesn’t stop miners from consuming the card for mining purposes.

Last month, NVIDIA made some moves to try to get more GPUs in the hands of gamers. The GeForce RTX 3060 is the company’s first video card with a hash rate limiter.

A lot of money is involved in cryptocurrency mining, and there are a lot of folks out there with amazing software and hardware hacking skills.

As such, I’m not surprised to see reports coming out of China of the first hack of the GeForce RTX 3060. Chinese miners have reportedly figured out a mod that boosts the hash rate of the GeForce RTX 3060 to over 45MH/s.

In the picture below, you can see a screenshot of a system with eight GeForce RTX 3060 video cards hitting over 45MH/s per card in Ethereum using the Dagger Hashi-Motto algorithm. With the hash rate limiter active, the card should only be capable of delivering 20-25MH/s.

WCCF Tech reports Vietnamese users independently verified this mod is the real deal.

NVIDIA GeForce RTX 3060 hash-rate limiter has been defeated, by the company itself, through a driver update. The RTX 3060 was announced by NVIDIA to be meant purely for gamers as it came with measures that make them unviable for mining. The card purportedly had a hash-rate limiter that detected workloads from typical crypto-currency mining algorithms, and spooled down GPU clock speeds, halving the mining efficiency of the card. The idea was to sour the milk for miners, so there could be inventory for gamers. PC Watch reports that the latest GeForce 470.05 drivers distributed by NVIDIA to developers through the Windows Insider Program defeats the hash-rate limiter, significantly improving mining performance of the RTX 3060.
