The new NBMiner version unlocks part of the mining power of the GeForce RTX 30 LHR series
In May of this year, Nvidia announced the launch of GeForce RTX 30 LHR series GPUs. Its LHR is the abbreviation of “Lite Hash Rate”, which means that the new GPU will have a new version of the cryptocurrency mining limiter, including the GeForce RTX 3080 Ti/RTX 3070 Ti, which will also have the same limit. Nvidia introduced the cryptocurrency mining limiter for the first time in the GeForce RTX 3060 released at the beginning of this year, but the subsequent outflow of the Driver for CUDA on SWL version 470.05 Beta driver made the so-called limit useless.
The emergence of the GeForce RTX 30 LHR series has indeed loosened the price of graphics cards. There are signs of gradual decline, and the supply situation is better than before. However, the recent mining software NBMiner v39.0 seems to have bypassed some of the limitations of NVIDIA. Its update log mentions that the computing power has been increased from 50% of the limit to 68% (only for the Ethash algorithm). Although it is not absolutely perfect, at least the mining performance of GPUs equipped with the new cryptocurrency mining limiter may be improved, which may make some miners consider buying GeForce RTX 30 LHR series graphics cards.
Some users on the Internet have used NBMiner v39.0 for testing, and the hash rate of GeForce RTX 3060 Ti/RTX 3070 Ti/RTX 3080 Ti equipped with the new cryptocurrency mining limiter has reached 40 MH/s, 50 MH/s, and 65 MH/s. The current version of NBMiner for GeForce RTX 30 LHR series GPUs is compatible with the existing NVIDIA drivers and supports Windows and Linux operating systems.
NBMiner did not mention specific methods to bypass the restrictions, and whether there is a possibility of further improvement in the future. Compared with a few months ago, the current graphics card market is relatively stable, but such a crack seems to bring a little uncertainty to the future trend of graphics card prices.
