BzMiner

What is BzMiner?

BzMiner is a command-line interface miner. It is launched using a .bat file or a configuration file, config.txt. It supports three algorithms: Ethash for EthereumPoW (ETHW) mining, etchash for Ethereum Classic mining, and Kawpow for Ravencoin. The program is integrated into HiveOS and MMPOS.

The automatic intensity dynamically adjusts the workload of the graphics card, reducing delays while maintaining a high hash rate.

Commission: This miner has a devfee of only 0.5%.

Requirements:

• At least one Nvidia graphics processor and Nvidia drivers;
• or at least one AMD GPU and AMD drivers.
• Windows or Linux.

How to Set Up BzMiner

Step 1 – Download the Miner from the provided link or (link).

Step 2 – Configure BzMiner After extracting the archive, create .bat files.

In the same folder as bzminer.exe, you need to create or modify an existing file with the extension .bat. Simply create a .txt file and give it the .bat extension. Open the .bat file with Notepad. Below is an example configuration for the Binance pool. You need to enter the following commands:

bzminer -a ethash -w username1 -p ethproxy+tcp://ethash.poolbinance.com:8888
pause

Instead of username1, simply enter your username from the Binance pool.

Step 3 – Start the miner

Now you need to start the miner. Important note! You don’t run bzminer.exe. Instead, you click on the newly created .bat file. So, after running the program for a few minutes, you will see a window with the hash rate

100% LHR Unlock

BzMiner has introduced a 100% LHR unlocker. If the card becomes unstable (for example, LHR exception), reduce overclocking and decrease --lhr_stability.

--lhr_stability affects both the hash rate and the stability of LHR unlock. Higher values will increase the hash rate but may lead to GPU failure. Lower values are more stable but may result in an instant LHR trigger, reducing the hash rate slightly. Experiment with this.

To disable LHR unlock, set –lhr_stability to 0. Default is 100.

LHR unlock can sometimes trigger “LHR exception.” If this happens, reduce the value of the --lhr_stability parameter. This “exception” allows the device to continue mining but at a much lower speed. Full device reboot is required for recovery, meaning a computer restart. BzMiner provides the --lhr_exception parameter, which, if set to true and the card experiences an LHR exception, will reboot the computer.

Config and Overclocking for Dual Mining

BzMiner allows you to set overclocking for each dual mining algorithm. Keep in mind that extreme overclocking parameters can more easily lead to a graphics processing unit (GPU) hang or failure in this scenario. For this reason, the configuration parameter oc_delay_ms is used to give overclocking time to activate before switching to the next algorithm.

Here is an example dual mining configuration with overclocking parameters for each algorithm:

        {
            "algorithm": "ethash",
            "wallet": "0000",

Bz Milner Miner Basic Commands:

-a, -a2 select the algorithm for main and dual mining;
--disable disables specified GPUs from mining. Separate using spaces. Use device IDs in the format pci_bus:pci_device (e.g., --disable 1:0 3:0). Use the --devices command to find device IDs. In HiveOS, this parameter is set in the additional configuration field;
-w specify your wallet address or pool account address in this field;
--w2 for specifying a second address when mining in dual mode;
--pool_password, --pool_password2 password, default is x;
-w, --worker, --worker2 worker name (rig). Set either as a separate parameter or after the wallet address with a dot;
--cpu-priority CPU processor load level during mining on the GPU. Default is set to 2. If the processor is struggling, you can set it to 0. Maximum value is 5;
--reconnect-on-fail-shares reconnect the miner to the pool in case of rejected shares from the pool;
--nvidia 1 mine only on Nvidia devices;
--amd 1 mine only on AMD devices;
-h, --help display all available commands.

Overclocking in Bzminer

--oc_lock_core_clock locks the core overclocking value. You can also set different values for graphics cards by specifying their IDs, for example, --oc_lock_core_clock 1000 1200 1300 (1000 for the graphics card with ID0, 1200 for the graphics card with ID1, 1300 for the graphics card with ID2); --oc_lock_memory_clock locks the memory overclocking value. You can also set different values for graphics cards separated by spaces; --oc_core_clock_offset sets the core clock frequency of the graphics card in MHz. You can specify values for multiple cards separated by spaces; --oc_memory_clock_offset sets the memory clock frequency of the graphics card in MHz. You can specify values for multiple cards separated by spaces; --oc_power_limit specifies the power limit (power consumption of the graphics card) in watts.You have the option to assign an individual value for each card, with the values separated by spaces. For example, --oc_power_limit 140 150 160 150.

Bz Miner Doesn’t Start

• If you are using Windows and the miner crashes immediately upon startup, add pause on the second line of the miner. Then, start the miner and read the error. After that, double-check the settings of your miner.
• If you are using HiveOS or any other OS, access the miner’s console and examine the logs of what is happening in the miner. After that, double-check the settings of your miner.
