The second batch of the RTX 30 is also known as LHR or Low Hash Rate, due to the fact that its mining rate in Ethereum is halved. According to NVIDIA to save the gamer market, bad thinkers say it’s for its CMP HX line. The RTX LHR Unlocker could end this limitation. What is it and how does it work?
When NVIDIA launched the first RTX 30s, they were seen and unseen, their ability to mine cryptocurrencies made them a sweet tooth for mining farms who didn’t mind paying huge sums to take it all. inventory to the anger of PC gamers who couldn’t renew their graphics card.
In order to satisfy everyone, the so-called RTX 30 LHR were born, basically a second delivery of the various graphics cards in the line with the BIOS and GPU ID changed so that when mining Ethereum they gave half the performance with as if to reduce the interest of farms for their mining RIGs. Well, an app has appeared that lifts this limitation.
What is RTX LHR Unlocker?
Well, it is an application whose task is to inject custom BIOS and GPU firmware which completely removes the limitations of Ethereum mining in the RTX 30LHR and therefore replaces those that come on the graphics card. According to the author of the application, a process of saving the one found on the card is carried out, but from there we cannot be sure because we have not tested it.
It must be taken into account that a change of this caliber of a GPU also implies modifying its behavior, to the point that it is necessary to use a special driver to download from a private server.
From here we state that the use of a BIOS other than that provided by NVIDIA may endanger the card and it is more than likely that we will lose the possibility of using them for other purposes such as playing with they. So anyone who replaces the BIOS using the RTX LHR Unlocker will have to be prepared to sacrifice their graphics card for the mining task and forget to use it for gaming or other tasks.
What is the performance that can be obtained in mining?
For starters, not all RTX 30s are compatible, for example, laptop models are not listed and neither is the RTX 3090 or RTX 3050. Although it is possible due to the fact that the first is very rare to see and the second has just been released. If you want to know the performance of each card when mining Ethereum, you have it in the image that accompanies these lines.
In any case, let’s not forget that the so-called Proof of Stake change is approaching, which will be a paradigm shift that will see graphics cards no longer be the go-to hardware for mining Ethereum. This will flood the market with used non-LHR RTX 30 units that will no longer be useful to miners. Those that have been modified with the LHR unlocker having lost gaming capabilities, they will be a harder sell if the original graphics card firmware and BIOS have not been backed up and restored.
