• etchash: Add support for NiceHash ETC pool.

• feature: ethash Add a new option --lhr-mode to select LHR unlock mode.
  • --lhr-mode 1 is the default mode and is the same as which in v41.5
  • Try to use --lhr-mode 2 if stability issue encountered in mode 1, for json config, use "lhr-mode": "2"
  • LHR v3 GPUs can only use mode 1
• feature: ethash Extend LHR unlocker to work with old driver versions. Starting from Windows v512.95 and Linux v515.x, LHR unlocker no longer works, make sure not to use these new driver versions.
• optimize: ethash small hashrate improvement on Nvidia GPUs.
• feature: Add GDDR6X memory temp in summary table for Linux.
• feature: Add GPU RAM type and GPU RAM vendor in log.
• feature: Add Nvidia driver versoin in summary table.
• feature: ethash Add eth_submitHashrate for nicehash (EthereumStratum) protocol.
• feature: If Overclock applies through nbminer, reset settings to stock when miner exit.
• feature: -mt option on windows does not require custom driver anymore (admin priviledge is required).
• NOTE: NBMiner versions older than v39.5 (not included) will run into issue when ETH reaches EPOCH 520 (Approx mid September). Please make sure to upgrade to a newer version before that if ETH is still with POW.

• fix: ethash Linux LHR unlocker can not unlock on certain GPUs.
• NOTE: NBMiner versions older than v39.5 (not included) will run into issue when ETH reaches EPOCH 520 (Approx mid September). Please make sure to upgrade to a newer version before that if ETH is still with POW.

feature: ethash 100% LHR unlocker added, for both Windows & Linux.

• Run nbminer with admin priviledge to get 100% LHR unlock
• Tested and verified on drivers: 512.15 for Windows, 510.60 for Linux.
• Other driver versions may have some compatibility issue.
• Previous LHR mode are removed.

Note1: Faster download links:
Windows: NBMiner_41.0_Win.zip
Linux NBMiner_41.0_Linux.tgz

Note2: If you run into issues, please change driver to recommened versions, and set your memclock 100 ~ 200mhz lower that previous LHR partial unlock situation

Update: AMD GPU issue confirmed in this release, will fixed soon in the next one. Mixed rig users can use seperate miner for AMD for now.

• fix: ethash v40.0 false detected as LHR lock under lastest Nvidia driver versions.
• feature: supports future LHR GPU models.

Binary update: fix AMD ethash crash

• feature: Add overclock options for Nvidia GPUs, require admin priviledge, accept comma seprated list to specify for each GPU.

  • -power-limit, -pl: Set power limitation of GPU. Examples:

    ​ Set PL in watts: -pl 200

    ​ Set PL in percentage of default PowerLimit: -pl 75% (in Windows bat file, need dual % , -pl 75%%)

  • -cclock: Set core clock in MHz. Examples:

    ​ Set clock offsets: -cclock 100 (Windows only)

    ​ Set locked clocks: -cclock @1500

  • -mclock: Set memory clock offsets in MHz (Windows only)

  • -lock-cv: Set locked core voltage of GPU in mV, support Turing and newer GPUs. (Windows only)

  • -fan: Set fan speed in percentage of GPU. (Windows only)

• feature: Display current LHR value in console summary table and web monitor.

• feature: -proxy options now support username & password for SOCKS5 proxy. format: -proxy user:pass@host:port

• feature: Web monitor changes, delete unused information for dual mining.

• feature: new options for log control.

  • -log-no-job: Turn off the New job line in console.
  • -log-cycle: Set to change the cycle of Summary table show in console and log, in seconds, defaults to 30.

• fix: ethash Change CPU share validation to independent thread, lower performance degradation when mining at very low difficulty pools.
