lolMiner KAS configuration file example

Understanding lolMiner and KAS Configuration Basics

lolMiner is a popular GPU mining software optimized for AMD and NVIDIA graphics cards, supporting multiple mining algorithms and cryptocurrencies. One of the supported blockchains is Kaspa (KAS), a high-speed, scalable blockchain that uses the BlockDAG structure and the kHeavyHash algorithm. To mine KAS efficiently, users must configure lolMiner with a correct configuration file that specifies pool connection details, wallet addresses, and hardware settings.

A configuration file for lolMiner is typically a .bat file on Windows or a .sh script on Linux. It allows users to predefine all necessary parameters, eliminating the need to manually enter commands every time the miner is launched. The configuration file must include the pool URL, port, wallet address, worker name, and optionally intensity settings and API control options.

Structure of a lolMiner KAS Configuration File

The core structure of a lolMiner configuration file consists of command-line arguments passed to the lolMiner.exe binary. Each parameter is separated by a space and begins with a double dash (--). Below is a breakdown of essential parameters used when mining KAS:

• --algo KAWPOW – This is incorrect for KAS; the correct algorithm is --algo KHEAVYHASH.
• --pool kaspapool.com:4444 – Specifies the mining pool domain and port.
• --user kaspa:qrd37x5x8c8v2fz5g7l9wz0k0q2f7y5x6t3j4h2k5m6n7p8q – Your Kaspa wallet address.
• --worker worker1 – A custom name to identify your mining rig.
• --tls 0 – Disables TLS encryption if the pool doesn't require it.
• --apiport 42000 – Enables local API access for monitoring hashrate and GPU stats.

These parameters are combined into a single executable command within the script file.

Creating a lolMiner KAS .bat Configuration File (Windows)

To create a working configuration file on Windows, follow these steps:

• Open Notepad or any plain text editor.
• Enter the full command line to launch lolMiner with KAS settings.
• Save the file with a .bat extension, such as mine_kas.bat.

Here is an example configuration:

@echo offcd /d 'C:\lolMiner\'lolMiner.exe --algo KHEAVYHASH --pool kaspapool.com:4444 --user kaspa:qrd37x5x8c8v2fz5g7l9wz0k0q2f7y5x6t3j4h2k5m6n7p8q --worker rig1 --tls 0 --apiport 42000pause

Important notes:

• The path C:\lolMiner\ must match the actual folder where lolMiner is installed.
• The wallet address must be valid and belong to you.
• The pool address must be accurate; popular KAS pools include kaspapool.com, k1pool.com, and luckpool.org.
• The pause command keeps the window open if an error occurs, aiding in troubleshooting.

Linux Shell Script Configuration for KAS Mining

On Linux systems, the configuration is done using a .sh script. The process is similar but uses bash syntax.

• Open a terminal and navigate to the lolMiner directory.
• Create a new script file: nano mine_kas.sh.
• Insert the following content:

#!/bin/bashcd '$(dirname '$0')'./lolMiner --algo KHEAVYHASH --pool k1pool.com:4444 --user kaspa:qrd37x5x8c8v2fz5g7l9wz0k0q2f7y5x6t3j4h2k5m6n7p8q --worker linux_rig --tls 0 --apiport 42000

• Save and exit (Ctrl+O, Enter, Ctrl+X).
• Make the script executable: chmod +x mine_kas.sh.
• Run it: ./mine_kas.sh.

Ensure the lolMiner binary has execute permissions and is in the same directory. The cd '$(dirname '$0')' line ensures the script runs from its own directory, preventing path errors.

Optimizing GPU Settings for KAS Mining

While the basic configuration connects to the pool, GPU performance tuning is essential for maximizing hashrate and efficiency. lolMiner supports several advanced parameters:

• --maxdualimpact – Adjusts memory clock for AMD cards.
• --lhrtune – Fine-tunes LHR (Lite Hash Rate) unlocking on NVIDIA cards.
• --pl – Sets power limit (e.g., --pl 75 for 75% power).
• --cclock and --mclock – Adjust core and memory clocks.

Example with tuning:

lolMiner.exe --algo KHEAVYHASH --pool kaspapool.com:4444 --user kaspa:qrd37x5x8c8v2fz5g7l9wz0k0q2f7y5x6t3j4h2k5m6n7p8q --worker tuned_rig --tls 0 --apiport 42000 --pl 80 --mclock 1000 --cclock -200

These values vary by GPU model. Users should test incrementally and monitor stability using tools like HWiNFO or MSI Afterburner. Overclocking too aggressively may cause crashes or rejected shares.

Troubleshooting Common KAS Mining Issues

Even with a correct configuration, issues may arise. Common problems and solutions include:

• 'Invalid username or password' error: Verify the wallet address is correct and starts with kaspa:. Some pools treat the entire wallet+worker as the username.
• Connection refused: Confirm the pool URL and port are up-to-date. Use ping kaspapool.com to test connectivity.
• Low hashrate: Check GPU utilization. If below 90%, consider adjusting --lhrtune or memory clocks.
• API port in use: Change --apiport to another number like 42001 if port 42000 is occupied.
• Crashes on launch: Ensure Visual C++ Redistributables are installed on Windows. On Linux, install libgomp1 if missing.

Enable logging by adding --logfile kas_log.txt to capture errors for later review.

Monitoring and Remote Management Setup

lolMiner provides a built-in web interface via the API port. After launching the miner, open a browser and go to http://127.0.0.1:42000/. This dashboard shows:

• Real-time hashrate per GPU.
• Accepted/rejected shares count.
• Uptime and pool latency.
• Temperature and fan speed (if GPU drivers allow).

For remote monitoring, configure your router to allow external access to the API port (not recommended without a firewall). Alternatively, use third-party tools like Minerstat or HiveOS that support lolMiner integration.

Frequently Asked Questions

Q: Can I use the same wallet address for multiple rigs?Yes, you can use the same kaspa:... wallet address across multiple rigs. Each rig should have a unique --worker name to differentiate them in the pool dashboard. The pool will aggregate all hashrate under one wallet for payout.

Q: What is the best pool for KAS mining with lolMiner?Popular pools include kaspapool.com, k1pool.com, and luckpool.org. Choose one with low fees, low latency, and good uptime. Test ping times to each pool’s server and review their payout thresholds and methods.

Q: Does lolMiner support auto-donate features for KAS?No, lolMiner does not have an auto-donate feature for KAS mining. Unlike some other miners, it does not reserve a percentage of hashrate for developer donation when mining KHEAVYHASH.

Q: How do I update lolMiner for KAS compatibility?Download the latest version from the official GitHub repository: https://github.com/Lolliedieb/lolMiner_Release. Extract the files and replace the old version. Always verify the checksum to avoid malware. Check the release notes for KHEAVYHASH-specific improvements.
