Creating a .bat File

In the folder with the miner, create or edit a file with the .bat extension using a text editor such as Notepad or Notepad++. When saving the file, make sure to select “All Files” as the file type, not “txt”, to avoid having .bat.txt at the end of the file name, which may prevent the miner from opening it. Your .bat file (let’s call it Dogecoin-binance_pool.bat) should contain the following text (Step 2):

Attention! For security reasons, Windows may block the opening of bat files. In this case, allow it to open in a pop-up window.

2. Enter the following command:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
cgminer --scrypt -o stratum+tcp://dogeminingpool.com:3009 -u DKs5E8nWJe2E5vYnVSoYqNjw2T17nGYUDo.RIG_NAME -p password

Configuring the Miner with Your Settings

After the -u (WALLET_ADDRESS) command, enter YOUR wallet address for the mined coin or USERNAME (pool login) (this tells the program where to send the cryptocurrency). RIG_NAME is the farm name. You can choose any name (e.g., as a test), but it must not exceed 32 characters and contain only letters and numbers (without special characters, such as $%»*; @). Be sure to replace the pool and wallet address with what you use in all files.

Tips for Effective Use of CGMiner

CGMiner is a powerful and flexible software for cryptocurrency mining. To maximize its potential, it’s important to know some useful tips and tricks. In this post, we will cover key aspects that will help you improve the performance and stability of your mining setup.

1. Optimize Your Hardware Settings

One of the most important aspects of successful mining is correctly configuring your hardware. Here are some recommendations:

  • Overclock Your GPU: Use the --gpu-engine and --gpu-memclock parameters to set the core and memory clock speeds of your GPU. Start with small values and gradually increase them while monitoring stability and temperature.
  cgminer --scrypt -o stratum+tcp://pooladdress:port -u yourUsername.workerName -p yourPassword --gpu-engine 1100 --gpu-memclock 1500
  • Temperature Control: Ensure your GPUs do not overheat. Use the --auto-fan and --temp-target parameters to automatically manage fan speeds and maintain optimal temperatures.
  cgminer --auto-fan --temp-target 75
2. Use Reliable Mining Pools

Choosing the right mining pool can significantly affect your earnings. Consider the following factors:

  • Low Fees: Look for pools with low transaction fees.
