New software can unlock LHR restrictions on all Nvidia 30XX/Ampere GPUs
One of the main features of the Nvidia 30XX series (since their early 2021 review for some models at least) was the inclusion of their LHR (lite hash rate) technology. What is that? Well, in a nutshell, it was designed to throttle GPU cryptocurrency mining performance by around 50% (more or less).
The key theory surrounding this was that if graphics cards didn’t deliver peak mining performance, industrial-scale operations wouldn’t want to buy them, which by proxy should have resulted in more PC landings. game consumers. – So, did it work? Well, considering you probably haven’t been able to buy one yet, we’d say not.
With Nvidia claiming their latest version LHR is basically unbreakable, however, following a report via Videocardz, it appears that new software may be able to remove the restrictions on all Nvidia 30XX Ampere graphics cards.
Nvidia LHR successfully bypassed by new software
Information regarding the ‘Nvidia RTX LHR v2 Unlocker’ (created by ‘Sergey’) has been posted online and appears to show that it is quite capable of removing the LHR restrictions found in the Nvidia 30XX series of graphics cards (and a number of GPU workstations). As part of the details, ‘Sergey’ confirmed the following hash rate performance observed after applying the software:
- RTX 3060 LHR V2 – up to 49 MH/s
- RTX 3060 Ti LHR – up to 61 MH/s
- RTX 3070 LHR – up to 57 MH/s
- RTX 3070 Ti – up to 69MHz/s
- RTX 3080 LHR – up to 100 MH/s
- RTX 3080 Ti – up to 115MHz/s
- RTX A2000 – up to 46MHz/s
- RTX A4000 – up to 67MHz/s
- RTX A4500 – not measured
- RTX A5000 – up to 110MHz/s
Before you start making up your mind about this software, however, it’s worth noting that it comes with a number of notable caveats that will likely deter the average consumer from bothering to try this!
LHR unlocked – but at a rather dubious cost!
To successfully unlock LHR restrictions, “Sergey” confirmed that the software applies a custom BIOS to the graphics card which also requires a custom set of drivers to work properly. In other words, while it successfully unlocks LHR, it would likely render the graphics card pretty much useless for any other kind of functionality (like gaming). – In other words, it’s not something you want to try “casually”.
In terms of major impact though, while it’s certainly curious software and a somewhat admirable job of successfully bypassing Nvidia LHR restrictions, it probably came a bit too late. Cryptocurrency mining is currently in a downward spiral largely due to the overall decline seen in the value of Bitcoin. Add in the significant changes coming to Ethereum (which may see GPUs entirely removed from this particular coin mining equation) and, more than anything, “Nvidia RTX LHR v2 Unlocker” may just represent a solid technical exercise rather than something worrying. – Especially since the creator has not yet made this software public and may choose never to do so. The cynic in me wonders if they hope to get offers from crypto organizations.
If nothing else though, it at least demonstrates that Nvidia’s revised LHR design has at least proven to be much more substantial than the original (which Nvidia itself removed thanks to one of its own driver releases beta).
