lolMiner is a free GPU mining program for Windows and Linux that supports NVIDIA, AMD and Intel graphics cards, as well as CPUs. It is aimed at hobbyist miners and rig operators who want a command-line tool with broad algorithm coverage and a small, transparent fee structure.
The project is open source and actively updated. Its release repository on GitHub is the main place to follow new builds, and the most recent update in the catalog data is from August 2025. Because mining income depends heavily on coin prices, network difficulty and electricity costs, it is worth testing any setup on your own hardware before running it around the clock.
What Is a GPU Miner and Who Is lolMiner For?
A GPU miner is a program that uses graphics card processing power to solve the cryptographic puzzles behind proof-of-work blockchains. Each valid solution is submitted to a mining pool or network, and successful miners receive a share of the reward.
lolMiner is intended for people who already understand the basics of mining and want direct control over their rigs. Home miners with a few cards, small farm operators and hobbyists testing new algorithms are the typical users. Beginners can use it too, but they should first read about wallets, pools and electricity costs.
Common Real-World Use Cases
A typical setup starts with a single gaming PC. The owner installs drivers, downloads the miner, points it at a pool and watches the hashrate in the console output. From there, many users move on to rigs with six or more cards, where stability and temperature management become more important than raw speed.
Some operators switch between algorithms depending on profitability. Because lolMiner supports many algorithms in one binary, switching often means changing a single parameter rather than installing a new program. Others run dual mining during periods when a card would otherwise sit idle.
Key Mining Terms Explained
Hashrate is the number of calculations a device performs per second and is the most common measure of mining speed. Pool mining means combining your hashrate with other miners so that rewards arrive more regularly. The developer fee is a small percentage of your hashrate that the software directs to its author.
Understanding these terms helps you read the miner's output. A stable hashrate with low rejected shares usually indicates a healthy setup, while frequent drops can point to driver problems, unstable overclocks or network issues.
Why Retuning Matters After Updates
Mining software updates can change how the GPU behaves under load. Release notes for this project point out that major code changes may require adjusting overclock and undervolt settings again for the best results and stability. Operators who rely on fine-tuned profiles should test each new version before moving an entire rig to it.
A practical approach is to update one machine first, compare hashrate, power draw and temperatures over several hours, and only then roll the change out to the rest of the farm.

How to install lolMiner on Windows
- 1
Download the release
Go to the official GitHub Releases page for lolMiner and download the Windows archive for the version you want. The current release line is 1.98. Avoid copies from unknown file-sharing sites, and download only from the official website or the official GitHub Releases page.
- 2
Verify the file
Compare the SHA-256 checksum of the downloaded archive with the value published on the release page, or verify the signature if one is provided. A mismatch means the file should not be used.
- 3
Extract the archive
Unpack the zip file to a dedicated folder, such as C:\lolMiner. Keeping the miner in its own directory makes it easier to manage batch files, logs and updates.
- 4
Update GPU drivers
Install current drivers for your graphics cards. NVIDIA cards need CUDA-compatible drivers, AMD cards need OpenCL support, and some features require newer driver branches. Driver versions also affect which features work.
-
Create a start script
Write a batch file that includes the algorithm, pool address, wallet and worker name as parameters. Start the miner from this file rather than typing commands each time, and test it with a short run before leaving it unattended.
System requirements
- Windows operating system with a current version of the graphics driver
- NVIDIA GPU with CUDA support, AMD GPU with OpenCL support, or Intel Arc graphics
- Sufficient power supply and cooling for the installed graphics cards
How to use lolMiner
lolMiner runs from the command line, so the setup is mostly about writing a correct start command. Once you know the coin, algorithm and pool you want to use, the process is straightforward.
- Open a command prompt in the folder where you extracted lolMiner.
- Choose the algorithm that matches your target coin, for example Autolykos for Ergo or kHeavyHash for Kaspa.
- Enter the pool address and port provided by your mining pool.
- Add your wallet address and an optional worker name so you can identify the rig in pool statistics.
- Run the command and watch the console for accepted shares and the reported hashrate.
- Save the working command in a batch file so you can restart the miner quickly after a reboot.
- Adjust overclock or undervolt settings in a separate tool, then compare hashrate and temperatures before making the change permanent.
Pros & cons
- Supports NVIDIA, AMD and Intel GPUs in one program
- Covers a broad list of mining algorithms
- Open source with a public release repository
- Developer fee is clearly documented per algorithm
- Command-line design suits scripted and multi-rig setups
- Requires comfort with the command line and configuration files
- Settings and tuning need to be checked again after major updates
- Dual mining requires extra experimentation to find the right ratio
- Profitability depends heavily on electricity costs and coin prices
- Mining software is often flagged by antivirus tools
Is lolMiner safe?
lolMiner should be downloaded only from the official GitHub Releases page or the project's official website. Verify the SHA-256 checksum or digital signature of the archive before running it. Never download mining software from forums, file mirrors or links shared in chat, since these are common sources of malware that can steal wallet data or hijack hardware.
Mining tools are often flagged by antivirus programs because they use the GPU heavily and communicate with pools. If your antivirus reports the miner, review the detection and consider adding an exception only for the verified folder. Never turn off your protection entirely. Keep your wallet keys separate from the mining machine when possible, and never enter a seed phrase on any third-party website.
- Official source only. Download from github.com/lolliedieb/lolminer-releases. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
lolMiner competes with several other GPU miners, and the right choice depends on the algorithms and vendors you use. Compared with GMiner, lolMiner places a strong emphasis on broad algorithm coverage and transparent fee documentation. Rigel is a NVIDIA-focused miner, while lolMiner handles AMD and Intel cards as well.
BzMiner and Nanominer also serve GPU operators, and their strengths vary by coin and pool. Older tools such as T-Rex Miner and NBMiner are no longer actively developed, so newer rigs often favor actively maintained alternatives. Testing two miners on the same workload is the most reliable way to decide.
