Ok - So it's all change!! You CAN now use Tis and LHR cards to mine - see the article below but for the moment we will leave "traditional" mining cards listed here!
NBMiner was the first to bypass the limiter by restoring up to 70% mining performance to Nvidia’s RTX 30-Series cards. While this brought back a large portion of the card’s mining power, it still left 30% unused. However, mining enthusiasts found another workaround. Cue T-Rex — a program that allows its users to dedicate the remaining 30% of GPU power towards mining a second cryptocurrency.
While T-rex lets users mine two currencies at once, only 30% of graphics card power can be dedicated to mining ETH. The remaining 70% can be put towards mining something less profitable instead. This is an interesting choice that might make the software less profitable to those who strongly prefer maximizing the much more expensive Ethereum mining potential.
