The creators of the popular mining software have learned to completely bypass the restrictions on Nvidia game cards that interfere with cryptocurrency mining. Moreover, they were able to run dual-mining on such cards and mine two cryptocurrencies simultaneously. However, this requires a careful approach to video card selection and does not work with bitcoin yet.
Nvidia lost
Developers of T-Rex mining software managed to bypass basic restrictions on GeForce RTX LHR series graphics cards and restore cryptocurrency mining performance, Tom's Hardware writes. At first they were able to unlock 70% of the original video card features, but it seemed to be not enough and they returned the remaining 30%, and in a very non-trivial way.
The creators of T-Rex were able to completely get rid of the limitations of the GeForce LHR line cards by launching mining of two cryptocurrencies simultaneously. The user who turned on this option in the virtual money mining software can give 30% to mining Ethereum, while the remaining 70 redistribute to "digging" the other cryptocurrency.
Quite a strange decision.
The developers of T-Rex did not specify what influenced the decision to limit the card's performance when mining Ethereum to only 30%, taking into account that it is the second most in demand and at a rate of cryptocurrency in the world. At the time of publication it was worth $3600 per "coin" (258.7 thousand rubles at the Central Bank exchange rate on October 8, 2020, CoinDesk statistics).
Miners won this round of confrontation. How will Nvidia respond?
Also there is no complete list yet of all the currencies that will get 70% of the video card's power. As Tom's Hardware cites not very popular Cornflux ($0.34, ), Ergo ($10.4, ) and Ravencoin ($0.12, ), but does not specify whether this "chip" works with the world's main cryptocurrency - bitcoin. Its rate is over $55,000.
Hardware limitations
The victory of T-Rex over Nvidia with its tricks cannot be considered complete. Nvidia has lost the battle, but the "war" is still going on.
The reason is that miners using T-Rex software in its current version will have to be very careful in their choice of a video card because of some hardware limitations. It is related to the video memory requirements, which vary from cryptocurrency to cryptocurrency. For example, if you mine Ethereum and Ergo at the same time, you will need a card with more than 8GB of video memory. A bunch of Ethereum plus Ravencoin or plus Cornflux needs a card that has more than 10 GB of memory on board, despite the fact that both currencies are noticeably cheaper compared to Ergo.
Because of this, users who want to try out dual-mining from T-Rex in action will have to bypass GeForce RTX 3060 Ti and GeForce RTX 3070 cards. They are not adapted to this kind of machinations due to insufficient memory capacity.
All the efforts were in vain.
The authors of T-Rex will continue to improve their work, but there is a high probability that their efforts will not bring the necessary results in the form of a new wave of mining on video cards. And this time it is not about Nvidia.
The developers of Ethereum cryptocurrency are going to undo all T-Rex's efforts directly. They are preparing to move their blockchain to the new Proof-of-Stake (POS) protocol and abandon the currently used Proof-of-Work (POW) just to reduce the popularity of video cards as a mining tool.
