The market situation is changing, but GMiner is most often used for:

Ethereum Classic (ETC)
Ravencoin (RVN)
Beam (BEAM)
Various Equihash coins

To maximize profitability, miners typically use profitability calculators (what to mine / minerstat , etc.) , choosing an algorithm and coin based on their cards, electricity rates, and current network difficulty.

Where can I safely download GMiner?

One of the main questions for any miner is: where to download GMiner to avoid getting a virus?

1. Official website and verified sources

The safe option is to always use:

GMiner’s official website (a domain like gminer.info or the one indicated by the developers themselves in their releases);
official pages on major platforms (for example, GitHub developers, if there is one).

When downloading:

make sure the domain is spelled correctly ;
Don’t open windows that offer you to “download an accelerated version,” “patched version without a dev fee,” etc.

2. Why you shouldn’t download repacks from forums and obscure websites

Modified versions of miners are an ideal environment for:

built-in viruses/trojans ;
stealers who steal access to wallets and exchanges;
hidden miners in the miner , which will work to their advantage.

No amount of savings on dev fees justifies the risk of losing all funds in wallets .

3. Additional security measures

After downloading:

Check the archive with an antivirus (even if it is an official source; antivirus software may give false positives, but an extra check won’t hurt);
If possible, compare the hash sums of the files (SHA-256, MD5) if the developers publish them;
Store the miner in a separate folder, excluded from automatic scans, so that the antivirus does not block its launch, but use manual checking for new versions.

System requirements and supported devices

GMiner is a lightweight miner, but hardware requirements depend on the algorithm and the size of the DAG file .

Supported GPUs

Nvidia :
- GTX 10xx, RTX 20xx, RTX 30xx, RTX 40xx series;
- It is desirable that the drivers are not too old, but also not the latest ones, if they are unstable.
AMD :
- Many models from RX 4xx/5xx to newer series;
- For some algorithms, support may be limited or less effective than on Nvidia.

Video memory capacity

For algorithms like Ethash / Etchash / Beam / Cortex, it is important that the video card has enough VRAM for DAG/processing:
- Typically, 4–6 GB and above is recommended (for certain algorithms and coins, 3–4 GB may be sufficient, but the “time reserve” will be small).
For KAWPOW (RVN) and a number of other algorithms, the VRAM requirements are more relaxed, but the more memory, the more comfortable it is for overclocking and optimization.

Supported OS

Windows 10/11 (64-bit);
Linux :
- common distributions: Ubuntu, Debian, etc.;
- specialized mining OS (HiveOS, RaveOS, etc.) – GMiner is usually already on the list of available miners.

Other requirements

CPU – there are no special requirements, any modern dual-core processor is sufficient;
RAM – from 4 GB, better from 8 GB;
Stable internet connection – to communicate with the pool;
Power supply with reserve power and high-quality cables.

GMiner Step-by-Step Setup: First Launch

Let’s look at the basic setup of GMiner using Windows as an example. In Linux, the logic is similar, but scripts .batare used instead..sh

1. Unpacking and file structure

After downloading:

Unzip the archive to a convenient directory, for example:
C:\Mining\GMiner\
Inside you will see:
- miner executable file ( miner.exeor similar name);
- a set of example scripts with the extension .bat(Windows) or .sh(Linux);
- sometimes a file configor READMEwith brief instructions.

2. Setting up a .bat file for Windows

The easiest way is to edit an existing example to suit the desired algorithm.

An example of a conditional command for mining ETC (Etchash) through a pool:

miner.exe --algo etchash ^
  --server etc-pool.example.com:4444 ^
  --user 0x1_ETC_wallet.RIG1 ^
  --pass x
pause

Where:

--algo— algorithm (etchash, kawpow, beamhash, etc.);
--server— pool address and port;
--user– your wallet and, if desired, the name of the rig separated by a dot ( .RIG1);
--pass— a password, often xor a set of parameters, depending on the pool.

3. Example of a batch file for Ravencoin (KAWPOW)

miner.exe --algo kawpow ^
  --server rvn-pool.example.com:3838 ^
  --user R_ADRES_RVN.RIG1 ^
  --pass x ^
  --tfan 70
pause

Additionally:

--tfan 70— an example parameter for fan control (if supported).

4. Launching the miner

Save the modified .batfile.
Double-click on it and the console will open.
GMiner:
- will create a DAG (for algorithms like Ethash/Etchash);
- connect to the pool;
- will start sending shares.

If you see regular accepted shares without frequent errors, everything is going according to plan.

GMiner Optimization: Overclocking, Power Consumption, and Stability

Without overclocking and power throttling, you either lose hashrate or pay extra for electricity.

1. Overclocking video cards

Overclocking is usually done through third-party programs :

Windows: MSI Afterburner, EVGA Precision, ASUS GPU Tweak , etc.;
Linux / HiveOS: Built-in overclocking tools via control panel.

General principles:

For Ethash / Etchash :
- we increase the memory frequency;
- We slightly reduce the core and limit the power limit.
For KAWPOW (RVN) :
- More often, core overclocking and proper power limit settings are important ;
- Memory can be overclocked moderately or not touched at all.

Always test:

minimal changes first;
Make sure there are no rejected shares or driver crashes.

2. GMiner parameters for stability

GMiner usually has a number of options like:

watchdog — automatic restart of the miner in case of errors;
failover pools – backup pools in case the main pool fails;
Automatic shutdown or restart of the card in case of overheating/errors.

Enabling watchdog and backup pools increases uptime and reduces downtime.

3. Temperature control and cooling

Optimum temperatures:

For most GPUs, the comfortable range is 50–65 °C (core);
It is better to keep GDDR6X memory at temperatures up to 90–95 °C ; above this temperature there is a risk of degradation.

Recommendations:

clean the rigs from dust;
use additional fans, thoughtful placement of cards;
Do not place the rig in a closed closet or small room without ventilation.

Dual mining in GMiner

One of GMiner’s interesting advantages is its dual mining support . This allows you to:

mine the main coin using one algorithm;
mine a second coin in parallel , usually with a little extra power consumption.

Common examples:

ETC + ZIL
Combinations with other coins, depending on the current support of the GMiner version.

Advantages of dual mining:

More profitable use of idle time (for example, ZIL is mined in short periods);
Additional income without a significant drop in the hash rate of the main algorithm.

Cons:

More complex setup (two pools, two algorithms, different parameters);
Possible increase in consumption and heating;
It doesn’t always pay off when electricity is expensive.

Dual mining makes sense to test selectively :

Set up a config for dual mining.
View profitability through pool statistics and calculators.
Compare it to classic solo mining of one coin.

Common mistakes and solutions

When working with GMiner, the same problems often arise.

1. DAG errors or miner crash at startup

Reasons:

not enough video memory;
too aggressive acceleration;
outdated drivers.

Solutions:

reduce overclocking (especially memory);
update GPU drivers;
Make sure the card meets the minimum VRAM requirements for the coin in question.

2. Low hashrate

Reasons:

incorrect overclocking settings;
default operation without optimizations;
The power limit is too low.

What to do:

Find the “reference” overclocking settings for your card on the Internet;
gradually increase the power limit to a reasonable value;
Check if the card is in power saving mode.

3. High percentage of rejected shares

Reasons:

unstable internet or high ping to the pool;
overheating and memory errors;
too aggressive acceleration.

Solutions:

change the pool to one that is geographically closer;
reduce memory and core overclocking;
improve cooling.

4. Frequent disconnects from the pool

Reasons:

problems on the pool side;
unstable provider;
blocking of ports or traffic by antivirus/firewall.

Solutions:

add a reserve pool to the batch file ;
set up the router, eliminate problems with Wi-Fi (use a cable if possible);
check your firewall/antivirus settings.

GMiner vs. other miners: what’s the difference?

GMiner competitors:

T-Rex is very popular on Nvidia, especially for some algorithms;
lolMiner is a flexible miner with a wide range of algorithms, and works well on AMD;
PhoenixMiner , TeamRedMiner , NBminer and others.

GMiner’s Strengths

Good performance on Equihash, Beam, Cortex and a number of other algorithms ;
High stability and convenient logging;
Dual mining support for a number of algorithms;
Transparent dev fee (usually around 1–2%, depending on the algorithm and version).

Possible disadvantages

On some algorithms (especially popular ones after the departure of ETH) T-Rex or other miners may be slightly more efficient ;
On purely AMD farms, it is sometimes more convenient to use specialized solutions (like TeamRedMiner);
Requires manual selection of optimal settings, just like any other miner.

In practice, many miners:

Testing multiple miners on the same rig;
Compare:
- hashrate;
- stability;
- rejections;
- ease of logging;
They settle on what provides the best balance of “profitability/stability/energy consumption” .

Conclusions and recommendations for using GMiner in 2025

GMiner remains a relevant miner for those who:

uses Nvidia and/or AMD video cards ;
mines ETC, Ravencoin, Beam, Equihash coins and other supported projects;
