New NBMiner 21.0 With Improved Performance and Stability for Grin29 and Grin31

6 Mar

The latest NBMiner 21.0 that has just been released comes with support for Aeternity (AE) as well as improved miner stability and performance for the Grin29 and Grin31 algorithms (Cuckaroo29 and Cuckatoo31). Performance wise the new version does seem to catch up to the competition regarding Cuckaroo29 hashrates (the latest Gminer is still slightly faster) and could currently be the fastest miner for Cuckatoo31 in terms of hashrate (at least for Windows on GTX 1080 Ti) compared to BMiner and GMiner. Stability wise Cuckatoo31 however could use some more improvements as we see the miner crashing on some systems that otherwise work just fine with competing miners.

We remind you that the NBMiner is a closed source GPU miner for Nvidia CUDA that is available for both Windows and Linux operating systems and it has the following developer fee built-in: tensority + ethash – 3%, tensority (Pascal GPUs) – 2%, tensority (Turing GPUs) – 3%, ethash – 0.65%, cuckaroo29 and cuckatoo31 – 2%.
