NBMiner v39.0: up to +70% max ETH mining hash rate on NVIDIA (Window/Linux)

NBMiner is a closed-source GPU miner for Nvidia CUDA and now AMD, which is available for both Windows and Linux operating systems. NBMiner GPU-miner for ETH, CFX, RVN, GRIN, BEAM, AE, BTM, SERO, HNS, BFC and many other popular cryptocurrencies.

Changes and new features in NBMiner v39.0

feature: ethash – New LHR mode for ETH mining on RTX 30 series LHR GPUs, supports Windows & Linux, allows ~70% of maximum unlocked hashrate.

  • This mode can be configured with the -lhr argument, now only works for ethash.
  • -lhr defaults to 0, which means that even if -lhr is not set, LHR mode with -lhr 68 will be applied to LHR GPUs if certain GPUs are detected.
  • Configure LHR mode by setting -lhr <value>, a certain value will tell the miner to try to achieve value a percentage of the maximum unlocker hashrate, for example. -lhr 68 would expect to get a 68% hashrate for the same GPU model without LHR.
  • A larger value of -lhr will result in a higher hash rate, but will have a higher probability of getting into a lock state, resulting in a much lower hash rate.
  • A good starting value for tuning is 68, which has been tested as stable on most hardware configurations.
  • -lhr value can be set for each GPU using a comma separated list, -lhr 65,68,0,-1 where -1 means disable LHR mode.

Note to the release

  • fails to unlock LHR hashrate under windows driver 471.11

Set up NBMiner

For the fastest possible start will be enough:

  1. Download archive with the program
  2. Unzip to any convenient location
  3. Change the wallet to your .bat file extension

The archive with the program contains ready-made examples for Grin, Ethereum + Bytom, a configuration file, as well as instructions in Russian.

open_web_monitor – html file to monitor the program through the web interface.

Examples of Quick Starts

  1. Edit the “.bat” file
  2. Change the username from the pool.
  3. The program is started by double-clicking the file with the extension .bat
DOWNLOAD NBMinerv 26.2 setup
  1. nbminer Name of the program to run.
  2. -a cuckarood – specify the algorithm of the mined coin.
  3. o stratum + tcp: //grin29.f2pool.com after building -o stratum + tcp: // specify pool address.
  4. : 13654 put a colon and specify the pool port
  5. -u rgz – after the -u key, specify the wallet address or login in the pool. Wallet can be opened on any convenient and safe exchange, or put the official wallet from the coin.
  6. . default – put a dot and specify the farm name (any)
  7. : x put a colon and a password (usually not required, so x)
  8. -long-format – display the program log
  9. -log creates a log file named log_.txt.
  10. -di 24 indicate the intensity of the program (for dual-mining)
