How to Mine Bitcoin with Cgminer 3.7.2 on Windows 64-bit OS
Bitcoin mining is the process of securing the Bitcoin network and creating new bitcoins by solving complex mathematical problems using specialized hardware and software. One of the most popular software for Bitcoin mining is Cgminer, which stands for Con Kolivas's GPU miner.
Cgminer 3.7.2 Windows 64 Download
Cgminer is an open-source software that supports a variety of devices, such as ASICs (application-specific integrated circuits), GPUs (graphics processing units), and FPGAs (field-programmable gate arrays). It also offers many features and benefits, such as:
Overclocking: You can increase the clock speed of your device to boost its performance and hash rate.
Monitoring: You can keep track of your device's temperature, fan speed, power consumption, hash rate, and other statistics.
Fan speed control: You can adjust the fan speed of your device to optimize its cooling and noise level.
Remote interface: You can access and control your device from another computer or mobile device using a web browser or a command-line interface.
Multi-GPU support: You can use multiple GPUs on the same computer to increase your hash rate.
CPU mining support: You can use your CPU as a backup device or for testing purposes.
Self-discovery of new blocks: You can automatically detect new blocks on the network using a mini-database.
Binary loading of kernels: You can load pre-compiled kernels for your device to improve its performance.
In this article, we will focus on Cgminer version 3.7.2, which is the last version that supports GPU mining. This version is compatible with Windows 64-bit operating system and can be used to mine various cryptocurrencies based on the Scrypt algorithm, such as Litecoin, Dogecoin, Feathercoin, etc.
Downloading Cgminer 3.7.2
The first step to use Cgminer is to download it from a reliable source. You can download Cgminer 3.7.2 for Windows 64-bit from here:
This is a zip file that contains the executable file (cgminer.exe) and some other files that are needed for Cgminer to run properly.
Before you extract the zip file, you should verify its integrity by checking its SHA256 hash value. A hash value is a unique string of characters that identifies a file and ensures that it has not been tampered with or corrupted.
You can use a tool like HashCalc or HashMyFiles to calculate the hash value of the zip file and compare it with the expected value provided by the source website.
The expected SHA256 hash value for Cgminer 3.7.2 zip file is:
If the calculated hash value matches the expected value, you can proceed to extract the zip file to a folder of your choice. For example, you can create a folder named Cgminer on your desktop and extract the zip file there.
Installing Cgminer 3.7.2
After you have extracted the zip file, you need to create a batch file that will launch Cgminer with the appropriate parameters. A batch file is a text file that contains a series of commands that are executed by the Windows command processor.
To create a batch file, you can use any text editor, such as Notepad or WordPad. You can name the batch file anything you want, but it must have the .bat extension. For example, you can name it start.bat.
The batch file should contain the following line:
cgminer.exe --scrypt -o stratum+tcp://[pool URL]:[pool port] -u [worker name] -p [worker password]
This line tells Cgminer to mine using the Scrypt algorithm and to connect to a mining pool of your choice. A mining pool is a group of miners who share their computing power and split the rewards. Mining in a pool increases your chances of finding a block and earning bitcoins.
You need to replace the following placeholders with your own information:
[pool URL]: The URL of the mining pool you want to join. For example, litecoinpool.org.
[pool port]: The port number of the mining pool you want to join. For example, 3333.
[worker name]: The name of your worker on the mining pool. You need to register on the mining pool website and create a worker for each device you want to use. For example, user1.worker1.
[worker password]: The password of your worker on the mining pool. You can usually set it to anything you want. For example, x.
For example, if you want to mine on litecoinpool.org with the worker name user1.worker1 and the password x, your batch file should look like this:
cgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:3333 -u user1.worker1 -p x
You can also add other parameters to customize your mining settings, such as:
--intensity: This sets the intensity of your device, which affects its performance and power consumption. The intensity ranges from 0 to 20, with higher values being more aggressive. The default value is 8. You can also use dynamic intensity by setting it to d.
--gpu-engine: This sets the clock speed of your GPU in MHz. You can increase it to overclock your GPU and improve its performance, but be careful not to overheat or damage your device.
--gpu-memclock: This sets the memory clock speed of your GPU in MHz. You can increase it to overclock your GPU and improve its performance, but be careful not to overheat or damage your device.
--gpu-fan: This sets the fan speed of your GPU in percentage. You can increase it to cool down your GPU and prev
