Learn how to set up and use MultiMiner—one of the most convenient cryptocurrency mining tools in 2025. Compatible with Windows, Linux, macOS, and ASIC devices. Step-by-step instructions, advantages, ready-made configurations, errors and solutions, and the best settings.

1. What is MultiMiner and why is it relevant in 2025?

MultiMiner is a free and user-friendly cryptocurrency mining program with a graphical interface, built on the BFGMiner engine . Unlike traditional console miners, MultiMiner offers a clear interface and automatic hardware configuration, making it an excellent choice for beginners and ASIC miners.

Why MultiMiner is still relevant in 2025:

• works on Windows, Linux and macOS ;
• supports ASIC, FPGA and GPU ;
• automatically detects equipment;
• can switch to the most profitable coin ;
• allows remote control of mining;
• is completely free and open.

While CGMiner and BFGMiner are often used via the command line, MultiMiner is an add-on with a user-friendly interface where most actions are performed with a mouse click.

2. Main functions of MultiMiner

2.1 Automatic equipment detection

When you first launch MultiMiner:

• scans the system;
• finds all available devices (ASIC, FPGA, GPU, CPU);
• offers options for algorithms and coins that can be mined.

This is convenient when a user has several ASICs or a mixed farm.

2.2. Easy mining pool setup

In MultiMiner you only need to specify once:

• pool address (URL),
• login/worker (wallet or worker name),
• password.

The program then remembers the settings and applies them to all or selected devices.

All pools are supported:

• NiceHash
• ViaBTC
• AntPool
• LitecoinPool
• other pools for SHA-256, Scrypt, etc.

2.3. Auto-switch to the most profitable coin

The Profitability Switching feature is one of the key reasons why MultiMiner is valued by miners.

Program:

• receives data on the current profitability of algorithms (via pool or service APIs);
• analyzes profit per unit of power;
• automatically switches devices to a more profitable algorithm or pool.

This helps:

• do not manually monitor the market;
• get maximum income with minimum participation.

2.4 Remote control and monitoring

MultiMiner supports:

• remote monitoring;
• Remote management of multiple farms.

Can:

• view hashrate and temperature;
• restart mining;
• change pools and settings even without being near the equipment.

This is especially convenient for owners of multiple ASICs: there is no need to connect to each one separately via the web interface.

2.5. Logs, graphs and statistics

The program shows:

• current hashrate for each device;
• chip temperature;
• fan speed;
• number of accepted and rejected balls;
• errors (HW errors).

This helps monitor stability and detect problems early.

3. Which cryptocurrencies can be mined using MultiMiner?

MultiMiner itself doesn’t limit the list of coins—it all depends on which algorithm your ASIC or GPU supports and which pool you’re using.

3.1 ASIC on SHA-256

With MultiMiner you can mine:

• Bitcoin (BTC)
• Bitcoin Cash (BCH)
• Namecoin (NMC)
• and other coins using the SHA-256 algorithm.

3.2. ASIC on Scrypt

If you have an ASIC on Scrypt:

• Litecoin (LTC)
• Dogecoin (DOGE) (via merged mining with LTC)
• Verge (XVG)
  and other Scrypt coins – depending on the pool.

3.3. GPU/CPU mining (via BFGMiner)

While MultiMiner’s primary focus is on ASICs and FPGAs, BFGMiner also supports GPU/CPU mining:

• Dash (X11);
• Digibyte;
• FTC, MONA, etc.

As of 2025, GPU mining via MultiMiner is no longer as popular as mining via specialized miners (Phoenix, TeamRedMiner, etc.), but the opportunity remains.

4. How to install and configure MultiMiner – step-by-step instructions

4.1. Step 1 – Download MultiMiner

10. Detailed ASIC settings in MultiMiner

Now for the more professional part: how to get the most out of ASICs using MultiMiner.

10.1. Operating profiles: ECO, Standard and Turbo

There are three types of modes typically used for ASICs:

• ECO (energy efficient)
  • slightly reduced frequency;
  • less noise and heating;
  • higher profit per 1 kWh.
• STANDARD (factory)
  • balance of hashrate and device resource;
  • Optimal for 24/7 mining.
• TURBO (acceleration)
  • increased frequency and hashrate;
  • higher load, temperature and risk of errors.

In MultiMiner, you can set different profiles for individual ASICs or groups of devices.

10.2. Setting the ASIC frequency and power

In the Hardware / Devices section you can:

• change the frequency (clock/frequency);
• set power limit (if ASIC supports it);
• control intensity .

Recommended approach:

1. Run ASIC on factory settings .
2. Make sure the temperature and hashrate are stable.
3. Increase the frequency in small steps (+25–50 MHz).
4. After each step, observe:
   • temperature;
   • number of HW errors ;
   • hashrate stability.

If:

• the errors are growing,
• Accepted – the ball is smaller than usual,
• the device reboots,

– it means the acceleration is too aggressive, roll back.

10.3 Fan and Temperature Control

Overheating is the main cause of ASIC failure.

In MultiMiner/BFGMiner you can:

• enable automatic fan control ;
• set the target temperature (e.g. 70–75°C);
• Set critical thresholds at which mining will stop.

Adviсe:

• aim to keep the chips at 75°C ideally;
• use tunnel ventilation and supply ventilation;
• Clean the equipment from dust.

10.4. Failover Pools

In MultiMiner, be sure to add:

• main pool – with the best profitability;
• 2-3 backup pools – in case of failure of the main one.

Settings:

• order of pools by priority;
• switching conditions:
  • pool is unavailable;
  • high ping;
  • many rejected-ball.

This way you will avoid downtime and loss of income.

11. Ready-made configs for popular ASICs in MultiMiner

Below are some sample configuration templates. They aren’t “perfect” for everyone, but they provide a good starting point.

⚠ Important: Overclocking may reduce the lifespan of your device and affect your warranty. Always test changes gradually.

11.1 Basic config for SHA-256 ASIC (e.g. Antminer S9)

Goal: stable 24/7 operation without crashes or overheating.

Algorithm: SHA-256
Pool: stratum+tcp://sha256.yourpool.com:3333
Worker: BTC_wallet_address.name
Password: x

Frequency: factory default
Target temperature: 70°C
Auto-fan: enabled
Failover pools: 2–3 backup pools
Auto-restart on failure: enabled
Logs: enabled

11.2. Energy-efficient configuration (ECO)

Goal: maximum profit per 1 kWh.

Algorithm: SHA-256 or Scrypt
Frequency: -10–15% of base frequency
Power limit: enabled (if available)
Temperature: up to 65–70°C
Fans: auto, but no less than 40–50%
Auto-profit switching: enabled (if supported by the pool)
Failover pools: configured

Result:

• hashrate is 10-20% lower;
• consumption is 20–30% lower;
• Often the profit on electricity is higher.

11.3. Turbo Config (overclocking for experienced users)

Frequency: +5–10% to base
Power limit: disabled or increased
Temperature: up to 75–80°C (strict control)
Fans: minimum 70–80%
Auto-restart on high HW errors: enabled
Watchdog: enabled
Logging: detailed

If after acceleration:

• the percentage of HW errors is growing;
• the actual hashrate decreases;
• crashes appear,

— it’s better to reduce the frequency or return to factory settings.

• parallel launch of other miners.

Solutions:

• do a clean installation of GPU drivers;
• disable overclocking and test stock frequencies;
• Disable other miners and resource-intensive programs.

13.3. Equipment noise and overheating

ASICs and rigs are always noisy and hot, but you can reduce the discomfort:

• switch some devices to ECO mode ;
• move the farm to a separate room;
• make air ducts and noise mufflers;
• use more powerful ventilation of the room.

14. Best MultiMiner Settings for ASICs

In 2025, the situation is as follows: grid complexity is growing, competition is increasing, and electricity prices are rising. Therefore, the key principle is:

Not the maximum hashrate, but the maximum profit per 1 kWh and stability.

14.1 General approach to setting up MultiMiner

Recommended:

1. Stability is more important than overclocking.
   Drops and downtime will eat into any difference in hashrate.
2. Energy efficiency.
   It’s often more cost-effective to reduce frequency and consumption than to burn electricity to zero.
3. Automation.
   Use:
   • Profitability Switching;
   • reserve pools;
   • auto-restart;
   • remote monitoring.

14.2. Recommended settings for a beginner

Ideal starting option in 2025:

• mode: Standard or easy IVF ;
• frequency: factory or -5–10%;
• temperature: up to 70–75°C;
• Auto-fan: on;
• 1 main + 2-3 backup pools;
• Auto-restart and watchdog are enabled;
• Monitor logs 1–2 days after launch.

This approach provides:

• stable operation 24/7;
• predictable income;
• minimal risk of breakdowns.

14.3. Settings for advanced miners

If you already have a large farm and experience:

• use multiple profiles :
  • daytime profile (IVF, when the tariff is more expensive),
  • night profile (more aggressive when the tariff is lower);
• Integrate MultiMiner with monitoring systems (via log files, API, scripts);
• Test new versions of BFGMiner first on a few devices, and then on the entire farm.
