Nvidia's LHR hashrate limitation for GeForce RTX GPUs can be easily bypassed by mining two crypto coins at the same time
It was apparently just a matter of time until clever crypto miners find a way to bypass the software algorithms of Nvidia's hashrate limitation that is built into the LHR models of current GeForce RTX graphics cards. It was already known that with a workaround, the NBMiner software was able to restore 50 to 70 percent of the mining performance of Nvidia RTX GPUs with the lite hash rate. The crypto miner software T-Rex now even goes a step further.
According to Tom's Hardware, the latest version of T-Rex not only allows miners to utilize up to 70 percent of the original hashrate of RTX GPUs, but also use the remaining 30 percent of performance to mine another cryptocurrency. For example, it is possible to use aforementioned 70 percent of the original hashrate to mine coins like Cornflux (CFX), Ergo (ERG) or Ravencoin (RVN), and then use the remaining 30 percent to mine the well-known cryptocurrency Ethereum (ETH).
Since cryptocurrencies have specific VRAM requirements, not every Nvidia GeForce RTX graphics card works well with the new dual mining feature in T-Rex. The Nvidia GeForce RTX 3060 Ti (from US$849 on Amazon) and GeForce RTX 3070 with their 8GB of GDDR6 memory are for example less viable for mining two different tokens at the same time. However, this may still be considered bad news for most gamers because cryptominers will probably continue to snatch all available Nvidia RTX GPUs, even the LHR variants.
