Ethereum (ETH) mining remains a popular way for individuals to participate in the blockchain ecosystem and earn cryptocurrency rewards. While Ethereum has transitioned to a proof-of-stake model with the Ethereum 2.0 upgrade, many users still refer to GPU-based mining practices that were widely used before this shift. This guide provides a comprehensive walkthrough of the traditional ETH mining process, focusing on hardware setup, software configuration, and best practices—ideal for those exploring decentralized networks or maintaining legacy systems.
Whether you're new to crypto or expanding your knowledge, understanding how Ethereum mining worked offers valuable insight into blockchain mechanics and network security.
Understanding Ethereum Mining
Ethereum is a decentralized, open-source blockchain platform that supports smart contracts and digital assets like Ether (ETH). Prior to its consensus upgrade, Ethereum operated on a proof-of-work (PoW) mechanism, where miners used computational power to solve complex mathematical problems and validate transactions.
The mining algorithm used was Ethash, designed to be memory-hard and resistant to ASIC dominance, making GPU mining the most effective method. Although Ethereum no longer relies on PoW mining, some forks—like Ethereum Classic (ETC)—still support it, keeping interest alive among enthusiasts.

Core Components of ETH Mining
Before diving into setup steps, it's essential to understand the key elements involved in mining:
- Mining Hardware: Primarily GPUs from AMD or NVIDIA.
- Mining Software: Programs that connect your hardware to the blockchain network.
- Wallet Address: Where mined coins are sent.
- Mining Pool: A group of miners combining computational power for more consistent rewards.

Step 1: Setting Up Your Mining System
A stable and optimized system is crucial for efficient mining operations.
Choose the Right Operating System
Most miners prefer 64-bit versions of Windows 7, 8, or 10 due to their broad software compatibility and driver support. While Linux is also viable, Windows offers a more user-friendly interface for beginners.
Ensure your system meets these minimum requirements:
- 64-bit architecture
- At least 16GB of virtual memory (pagefile)
- Updated motherboard BIOS supporting multiple GPUs
Install GPU Drivers
Graphics drivers play a vital role in maximizing performance and stability.
For AMD Radeon R9 4XX series or newer GPUs:
- Download and install the latest official drivers from AMD’s website.
For older AMD cards (pre-R9 4XX):
- Use driver version 15.12, known for better compatibility with mining software.
Always uninstall old drivers completely using tools like Display Driver Uninstaller (DDU) before installing new ones to avoid conflicts.
Step 2: Download and Configure Mining Software
Once your system is ready, it’s time to set up the actual mining application.
Select a Reliable Miner
Popular Ethash-compatible miners include:
- Claymore’s Dual Miner
- PhoenixMiner
- GMiner
- T-Rex Miner
Choose one based on your hardware and preferred features such as low developer fees or remote monitoring.

Set Up Your Wallet Address
You’ll need an Ethereum-compatible wallet to receive mined coins. Options include:
- MetaMask
- Trust Wallet
- Ledger (hardware wallet)
- Exchange deposit addresses (e.g., OKX)
Copy your public wallet address—it will replace the default one in the mining software configuration.
Edit the Batch File
Most miners come with a .bat file (e.g., start.bat) that launches the program. Open it with Notepad and modify the following:
miner.exe -o stratum+tcp://POOL_ADDRESS:PORT -u YOUR_WALLET_ADDRESS -p xReplace:
POOL_ADDRESSwith your chosen mining pool URLYOUR_WALLET_ADDRESSwith your actual wallet address
Save the changes and double-click the file to start mining.
Recommended Mining Pools
Joining a mining pool increases your chances of earning regular payouts by combining hash power with other miners.
Top Ethereum (ETH) Mining Pools:
- F2Pool – One of the largest global pools
- Nanopool – User-friendly with low thresholds
- DwarfPool – Known for reliability and fast payouts
- Coinotron – Supports multiple cryptocurrencies
- Ethfans Pool – Community-driven and transparent
For Ethereum Classic (ETC):
- MinerGate – Beginner-friendly interface
- Epool.io – Focused on ETC mining
- Coinotron – Also supports ETC
- MinerHub – Stable performance and low fees
Choose a pool based on fee structure, server location, payout frequency, and user reviews.
Frequently Asked Questions (FAQ)
Q: Is Ethereum mining still profitable in 2025?
A: Traditional ETH proof-of-work mining is no longer possible after the Merge. However, mining on Ethereum forks like Ethereum Classic (ETC) remains active. Profitability depends on electricity costs, hardware efficiency, and coin prices.
Q: Can I mine Ethereum with my home PC?
A: Yes, if your PC has a compatible GPU (AMD or NVIDIA). However, dedicated rigs with multiple GPUs yield better returns. Always calculate break-even points using online profitability calculators.
Q: Why does my miner crash or close immediately?
A: This "flash closing" issue usually stems from missing Visual C++ Redistributables, incorrect driver versions, or antivirus interference. Reinstall drivers, disable antivirus temporarily, and ensure all system dependencies are installed.
Q: What happens to my mined coins?
A: Coins are sent to your specified wallet address once the pool’s payout threshold is reached. Check your wallet regularly and consider transferring funds to cold storage for security.
Q: Do I need internet 24/7 for mining?
A: Yes. Continuous internet connectivity ensures your miner stays synced with the pool and contributes effectively to block validation.
