Review

NBMiner - is a graphics card (GPU) mining software. Works only with NVIDIA and AMD cards.

How to use NBMiner

Step 1 - Download the miner

Download NBminer, unpack it into a separate folder and find start.bat. NBMiner download

Configure a batch file for KawPow

Open the file start.bat with Notepad ++ or any suitable text editor and edit the file:

Here is an example NBMiner .bat file for a Beepool (Ravencoin):

nbminer -a kawpow -o rvn-pool.beepool.org:9531 -u RAXCRKF2JdYwYLn2RiMxDPNgvKMwfVrjY9
pause
		

Step 3 - Launch NBMiner

Save this file and then double click start.bat, to start mining. When the word “Accept” is displayed in the CMD window, it means that you have successfully submitted your solution to the pool.

Example for Binance Pool

STRATUM: ethproxy+tcp://ethash.poolbinance.com
PORT: 8888
Username: username1
Password: default

This is how the NBMiner batch file for ETH will look like on the Binance Pool:

NBMiner batch file

To configure a batch file for MTP, we need to enter 5 commands one by one:

NBMiner batch file

  1. nbminer - the name of the launched file
  2. ethash - algorithm for mining
  3. ethash.poolbinance.com - pool address
  4. 8888 - pool port
  5. username1 - username from the mining account on the exchange.

This is how the finished NBMiner batch file will look like:

nbminer -a ethash -o ethproxy+tcp://ethash.poolbinance.com:8888 -u username1.default -log

Setup for NiceHash

Here is a batch file for NiceHesh:

nbminer -a kawpow -o stratum+tcp://kawpow.eu.nicehash.com:3385 -u 3LZhp4g3m7YWqR4hAPrZsKWbyo7hRBmqvy.nbminer -log
pause

Unlock LHR Cards in Nicehash using NBMiner - Step-by-Step (3070 TI Tested)

In this video I will show how to improve Ethereum mining performance on LHR cards within Nicehash using NBMiner's new logic to improving hashrate on LHR cards [STEP by STEP].

Monitoring and profit

After the miner stabilizes for about 10-15 minutes, you can check the status of work and profit on the “Income” page in your account on the exchange or on the pool that you have chosen.

Versions

40.1

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

39.7

  • feature: LHR mode support new GA104 version of 3060;
  • feature: ethash Turn on LHR mode by default for 3060 v1;
  • fix: ethash Fail to detect LHR lock on certain situation;
  • fix: Nvidia GPU power consumption issue on certain rig config;
  • delete: support for sero.

39.5

feature: ethash new low power LHR mode, add -lhr-mode option.

  • -lhr-mode 2 is the default LHR mode, which is the new lower power mode.
  • -lhr-mode 1 changes LHR mode to old version, which is the same as v39.2
  • -lhr-mode 1 is suitable for only power limit bounded GPU, can achieve higher hashrate than mode 2
  • -lhr-mode 2 is able to achieve lower average power and temperature. espacially suitable for GPUs with gddr6x e.g.3070ti, 3080, 3080ti. Power consumtion is fluctuating in this mode, better be used with locked core clock.

feature: -lhr support decimal value

feature: for LHR GPUs, when mining lock is detected, miner will automatically decrease -lhr value by 0.1, and continue mining. max decrease times is 10, which sums to 1.0

fix: higher CPU usage when set --share-check 0.

39.2

  • feature: ethash added LHR lock detection and recovery in LHR mode.
  • fix: ergo more robust protocol handle.

39.1

  • optimize: ethash improve hashrate of LHR mode 1 - 2%,default value of -lhr changes from 68 to 69,manually set to 70 is also very promising.
  • fix: kawpow issue of v39.0
