Nvidia launched the GeForce RTX 30 LHR series GPU in May of this year, and its LHR is the abbreviation of “Lite Hash Rate” which means that these GPUs will have a new version of the cryptocurrency mining limiter, and the subsequent GeForce RTX 3080 Ti/RTX 3070 Ti will also have the same limit. Nvidia introduced the cryptocurrency mining limiter for the first time in the GeForce RTX 3060 released earlier this year. However, the 470.05 Beta driver for CUDA on SWL that was released subsequently made the so-called restrictions in vain.
About two months ago, the mining software NBMiner increased the computing power from the limit of 50% to 68% (only for the Ethash algorithm), allowing the GeForce RTX 30 LHR series graphics cards to perform better in mining. However, close to 70% of the computing power is obviously not enough for the miners, which means that 30% of the computing power is wasted. According to TomsHardware, another mining software, T-Rex, tries to improve the mining utilization rate of GeForce RTX 30 LHR series graphics cards through other methods.
It should be noted that neither NBMiner nor T-Rex can completely counter NVIDIA’s new version of the cryptocurrency mining limiter for the time being. There are still some protective measures that need to be cracked, just to increase the utilization rate as much as possible. Moreover, T-Rex is temporarily the closest mining software to 100%.
Somewhat strangely, this method of T-Rex cannot use 70% of the computing power on Ethereum, and it is very likely that it will not be able to maximize revenue for miners. In addition, different encryption currency combinations have different requirements for graphics cards. Some combinations require more than 8GB or even 10GB of video memory. Graphics cards with 8GB of video memory like GeForce RTX 3060 Ti/RTX 3070 LHR will be limited in use.
