NBMiner 27.7 – With improvements for Nvidia Mining HNS and HNS + ETH

NBMiner 27.7 - С улучшениями для Nvidia Mining HNS и HNS + ETH

GitHub: DOWNLOAD NBMiner v27.7

The latest NBMiner 27.7 update comes with improvements for Handshake (HNS) and HNS + ETH Dual mining on Nvidia GPUs, bringing slightly better performance, as well as some fixes such as NVML initialization failure in certain cases and ETH mining on NiceHash. With the latest performance improvement, NBMiner 27.7 is again becoming the leader in mining performance Handshake from the latest GMiner. With the latest performance improvements, the 6×1080 Ti mining rig is approaching the Blackminer FPGA with HNS support, although the GPUs are still a bit slower and consume a bit more power. However, HNS mining is now probably still worth it when the first Handshake ASIC miner is expected in June.

  • As a reminder, NBMiner is a closed-source GPU miner.
  • The miner for Nvidia video cards, and now, not so long ago, began supporting AMD cards.
  • NBMiner available for both Windows and Linux operating systems (x32 and x64 bit)
  • DEV-Fee:
    • tensority(Pascal) 2%,
    • tensority(Turing) 3%,
    • tensority_ethash 3%
    • ethash 0.65%
    • cuckaroo & cuckarood & cuckatoo & cuckoo_ae & cuckaroo_swap 2%
    • progpow_sero 2%
    • sipc 2%
    • eaglesong 2%, eaglesong_ethash 3%
    • bfc 3%
    • hns 2%, hns_ethash 3%

What’s New in v27.7:

  • Fix ETH mining on NiceHash
  • Fix NVML initialization failure on certain cases.
  • 修复ETH Nicehash协议
  • 修复部分情况下NVML初始化失败的问题

Starting and Configuring NBMiner

For the quickest start, it will be enough:

  1. Download archive with the program
  2. Unzip to any convenient place
  3. Change wallet to your own in a file with the extension .bat

file folder DOWNLOAD NBMinerv 26.2

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

OhGodAnETHlargementPill-r2 — tablet (patch) for video cards with GDDR5X memory to maximize the hashrate.

open_web_monitor — html file for monitoring the program through the Web interface.

Quick Launch Examples

  1. Edit file «grin-f2pool.bat»

  2. Change the username from the pool.

The program starts by double-clicking on the file with the extension .bat

Let’s now look at the setting in more detail.

customization DOWNLOAD NBMinerv 26.2
  1. nbminer is the name of the program to run.

  2. -a cuckarood indicate the algorithm of the mined coin.

  3. o stratum+tcp://grin29.f2pool.com after the construction -o stratum + tcp: // specify the address of the pool.
  4. :13654 put a colon and indicate the port of the pool

  5. -u rgz after the -u switch specify the wallet address or login on the pool. Wallet can be opened at any convenient and secure exchange, or put an official wallet from coins.
  6. .default put a point and indicate the name of the farm (any)

  7. 😡 put a colon and specify a password (usually not required, so x)

  8. -long-format display the program log

  9. -log create a log file named log_.txt.

  10. -di 24 indicate the intensity of the program (for dual mining)

A ready-made example of what we ended up with for the Grin coin using the cuckaroo29d algorithm

nbminer -a cuckarood -o stratum+tcp://grin29.f2pool.com:13654 -u rgz.default:x -long-format -log -di 24

Example for Ethereum + Bytom dual mining:

nbminer -a tensority_ethash -o stratum+tcp://btm.f2pool.com:9221 -u 0x0034335cc77e2e2b84c53683ef96c25e1486d5f3.dmdefault -do ethproxy+tcp://eth.f2pool.com:8008 -du 0x360d6f9efea21c82d341504366fd1c2eeea8fa9d.dmdefault -log -di 16

—temperature-limit Set temperature limit video cards, if it exceeds the specified one, the program will stop working video cards for 10 seconds and check if the card has cooled below a predetermined values. If so, then mining will continue, if not, there will be a pause extended. Example: –temperature-limit 75 means that when when the temperature reaches 75 °, the program will begin to pause and check every 10 seconds, whether the temperature has decreased to start again.


-i, —intensity Specify a comma-separated list of intensities for maps

-api Host and port for servicing the REST API.

—grin29-fork-height Change “height” to check if the algorithm changes automatically when grin29 makes a hard fork. Default: 262080

Problem solving

The program crashes or does not start

If the program does not work stably or crashes, then you need to increase the virtual memory of the system:

NBMiner v26.2 настройка windows

We expose the page file in the system

Control Panel \ All Control Panel Elements \ System – Additional system parameters – Advanced tab, then Options, again the Advanced tab.

We find the Virtual memory settings, click Change. Remove a tick from the item “Automatically select the size of the swap file” and put checkbox “Specify size”. Specify the desired size in MB (Example for 6 cards – 45000). Click on the Set button. Reboot the farm.

Failed to login mining pool, please check mining pool username

The connection parameters to the pool are incorrectly specified in the username key (pool login or wallet address)
