GMiner

GMiner is a closed-source command-line GPU miner for NVIDIA and AMD graphics cards. Since 2018 it has been a common choice for Equihash, KawPow, Autolykos2 and kHeavyHash rigs. People searching “gminer” usually want one of three things: whether it still works, which algorithms it supports and how it compares with lolMiner and other current miners. In short, it still runs, but development has stopped.

The last release, 3.44, came out on 6 March 2024. We checked the official GitHub repository again on 1 October 2026. The README, EULA and brand policy were edited during 2026, but no new miner build has been published. Use GMiner if it already suits your cards and coin. For new cards or new algorithms, look at an actively maintained miner first.

GMiner at a glance

What it does

• Mines on NVIDIA and AMD cards from one binary, and you can switch off either platform on a mixed rig.
• Takes the dev fee continuously instead of in timed bursts, which the developer says suits PPLNS pools better.
• Checks DAG generation and shares on the CPU and warns you when a memory overclock produces errors.
• Pauses a card when it reaches a GPU or memory temperature limit, and resumes once it cools.
• On Windows, can set core and memory clocks, voltage, power limit, fan speed and a fan target temperature from the command line.
• A watchdog restarts the miner, or optionally the whole system, after a crash or a lost pool connection.
• Supports failover pools, SSL pool connections, SOCKS5 proxies and Tor.
• Has a built-in statistics web server so you can watch the rig from a browser.

How miners use it

Start mining one algorithm

1. Extract the Windows zip or Linux archive into a folder of its own.
2. Run miner --list_devices to see the card numbers GMiner assigns.
3. Start with the algorithm, pool and wallet. On Windows the executable is miner.exe; most people put the line in a .bat file.

miner --algo kawpow --server pool.example.com:3333 --user YOUR_WALLET_ADDRESS.rig1

Add a failover pool and temperature limits

Give a second --server/--user pair for the backup pool. GMiner switches back to the main pool once it returns. Temperature limits can be set once for all cards or once per card:

miner --algo autolykos2 --server pool.example.com:3333 --user YOUR_WALLET_ADDRESS.rig1 --server backup.example.com:3333 --user YOUR_WALLET_ADDRESS.rig1 --templimit 80 --templimit_mem 100

Tune a Windows rig from the miner

1. Run the miner as administrator. Clock, voltage and memory-tweak options need it.
2. Set values per card in device order. For NVIDIA, --cclock and --mclock are offsets; for AMD they are absolute clocks.
3. Use --tfan with --tfan_min/--tfan_max to hold a target temperature instead of a fixed fan speed.

miner --algo kheavyhash --server pool.example.com:3333 --user YOUR_WALLET_ADDRESS.rig1 --pl 70 --tfan 65 --tfan_min 30 --tfan_max 85

Watch the rig remotely

Add --api 10050 and open port 10050 of the rig in a browser on your LAN. Keep that port closed to the internet.

Install and first run

Windows: extract the archive to a folder such as C:MinersGMiner. Use a recent NVIDIA or AMD driver. Run as administrator only if you use the overclocking or memory-tweak options.

Linux: extract the tar.xz archive and run ./miner with the same options. You need the proprietary NVIDIA driver, or a working OpenCL stack for AMD. The clock, fan and power-limit options are Windows-only, so on Linux you tune with your driver tools or your mining OS.

Antivirus: Windows Defender and other antivirus products often flag GPU miners as potentially unwanted software. Criminals bundle the same miners into malware, so the detection is about the type of program rather than proof of infection. Get GMiner only from the official GitHub releases page and check the file name and version against it. Do not switch off protection for the whole system.

Mine only on hardware you own or are allowed to use. Overclocking and undervolting through the miner can cause crashes and may affect your warranty, so change one value at a time.

Limitations

• Development has stopped in practice: 3.44 (March 2024) is the last build, and nothing newer was out as of 1 October 2026. Newer GPUs, drivers and algorithms released since then have not been tested or added.
• Closed source with a mandatory dev fee of 1–5% per the official README and release notes. Cortex and Dero sit at the top of that range.
• Several supported algorithms matter less than they did: Ethereum moved to proof of stake in 2022, and kHeavyHash (Kaspa) is now mined mostly on ASICs.
• Overclocking, fan and power-limit options work only on Windows.
• Whether mining pays depends on electricity price, card efficiency and coin prices, so treat any calculator figure as an estimate, not a promise.

GMiner vs alternatives

The most common comparison is lolMiner, which supports AMD and NVIDIA and published releases in 2025. For NVIDIA-only rigs, Rigel is updated regularly (1.23.2 in April 2026) and lists its fee per algorithm. OneZeroMiner is another actively updated closed-source GPU miner, with a release in September 2026. If you would rather not maintain command lines, a mining OS such as Hive OS lets you pick and configure miners from a web dashboard.

FAQ

Is GMiner still updated?

No new miner build has appeared since 3.44 on 6 March 2024. The repository text was edited in 2026, but there were no releases.

Where is the official GMiner download?

The developer names the GitHub releases page of develsoftware/GMinerRelease as the official download source, with gminer.pro as the website. Check the version and file name there before you run anything.

Is GMiner safe?

The official build is a legitimate miner, but antivirus tools often flag it as potentially unwanted because miners are abused in malware. Only use copies that match the official release page.

GMiner vs lolMiner: which should I use?

Both support NVIDIA and AMD. lolMiner is still maintained, while GMiner is frozen at 3.44, so for new setups test lolMiner or another current miner first.

Does GMiner work with AMD cards?

Yes. It uses OpenCL for AMD and CUDA for NVIDIA. Some features, such as memory tweaks and the LHR options, apply only to NVIDIA.

What is the GMiner dev fee?

Most algorithms carry 2%, kHeavyHash and KarlsenHash 1%, and Cortex and Dero 5%, according to the official README and release notes.

Is GMiner mining profitable?

That depends on your electricity cost, your cards and the price of the coin you mine. Check a current calculator with your own power price before running a rig around the clock.
