Performance Techniques Available with Custom Firmware
Custom firmware offers a range of advanced techniques that take mining rig performance to the next level. These tools allow miners to fine-tune their hardware, boosting both efficiency and profitability far beyond what stock firmware can achieve.
Overclocking for Higher Hashrate
Overclocking pushes ASIC frequencies beyond factory settings, increasing hashrate by 10–20% in many cases. This boost directly translates to mining more Bitcoin daily.
But overclocking isn’t without its challenges. Higher clock speeds mean more power consumption and heat, which can strain your hardware if not properly managed. To overclock safely, keep ambient temperatures between 64–73°F and use the real-time monitoring tools provided by custom firmware. These tools help you track stability and revert settings if something goes wrong.
In areas with low electricity costs, the increased hashrate can outweigh the added power expenses, making overclocking a worthwhile strategy. For miners looking to balance performance and energy use, undervolting offers another option.
Undervolting for Lower Power Costs
Undervolting reduces the operating voltage of ASICs while maintaining a stable hashrate. This method can cut power usage by up to 15%. By finding the lowest voltage that ensures stable operation, you can eliminate wasted energy. Custom firmware makes this process precise, allowing you to tweak voltage curves and even disable inefficient chips so power is concentrated where it’s most effective.
This technique is especially useful in regions with high electricity rates or limited cooling options. Lower power consumption also means less heat, reducing the risk of thermal throttling and improving overall stability.
Auto-Tuning and Individual Chip Settings
Auto-tuning is one of the standout features of custom firmware. It adjusts the frequency and voltage of each chip individually, accounting for their unique performance characteristics. This process can boost energy efficiency by 10–20% compared to stock firmware.
For example, one study showed an 18.67% efficiency improvement - reducing energy usage from 15.10 J/TH to 12.6 J/TH - after switching to optimized settings. Auto-tuning typically runs during setup and can be repeated periodically to adapt to changing conditions. Combined with dynamic fan and temperature management, this feature ensures your hardware operates at peak efficiency.
Temperature and Fan Management
Custom firmware also excels in thermal management. Instead of running fans at fixed speeds, it adjusts fan performance dynamically based on chip temperatures. This approach minimizes unnecessary fan wear, reduces noise, and prevents overheating.
For instance, during cooler weather or lighter workloads, fan speeds can be reduced to save energy and lessen mechanical stress. When temperatures climb, the firmware ramps up fan speeds to maintain safe operating conditions. In larger mining setups, coordinated fan profiles improve cooling across multiple rigs.
| Technique | Primary Benefit | Typical Performance Gain | Key Consideration |
|---|---|---|---|
| Overclocking | Higher hashrate | 10–20% increase in hashrate | Increased power and heat |
| Undervolting | Lower power costs | Up to 15% power savings | Requires careful tuning |
| Auto-Tuning | Optimal efficiency | 8–20% efficiency improvement | Needs advanced firmware |
| Fan Management | Extended hardware life | Reduced mechanical wear | Must prevent overheating |
By combining these techniques, miners can craft a tailored optimization strategy. For instance, undervolting and auto-tuning are often paired to maximize efficiency, while overclocking is reserved for situations where electricity costs are low, or hashrate is the priority. These methods not only improve performance but also support more sustainable mining practices.
For those who prefer to skip the technical details, managed services like Sazmining handle firmware optimization and performance tuning for you. These services ensure your rigs are running at their best, so you can focus on growing your returns.
Step-by-Step Custom Firmware Installation Guide
Installing custom firmware can significantly improve your rig's performance, but it requires careful preparation and execution. Follow these steps to ensure a smooth process.
Getting Ready for Firmware Installation
Before diving in, confirm that your hardware is compatible with the custom firmware you’ve chosen. Not every firmware version works with all ASIC models, and using the wrong one could permanently damage your device. Check the official documentation or the firmware provider's website to verify compatibility with your specific ASIC model and hardware revision.
Make a backup of your current firmware and settings. Most ASIC miners allow you to download the existing firmware through their web interface. Save this file, along with your configuration details like pool settings, worker names, and any custom tweaks. This backup will be crucial if you need to restore your device later.
Understand the risks involved. Installing custom firmware might void your manufacturer’s warranty and carries the possibility of "bricking" your device if something goes wrong. To reduce these risks, stick to reputable firmware providers, follow their official installation instructions carefully, and keep your backup accessible.
Lastly, ensure you have a stable network connection. A wired Ethernet connection is much safer than Wi-Fi for this process, as any interruption during installation could corrupt the firmware.
Installing and Setting Up Custom Firmware
Start by downloading the correct firmware file from the official provider. Make sure to verify the file's integrity using the checksum or hash values provided. This step ensures that the file hasn’t been corrupted or tampered with during download.
Next, access your miner’s control panel by entering its IP address into your web browser. Navigate to the firmware update or system upgrade section, upload the new firmware file, and follow the on-screen instructions. Do not power off your device during this process, as it could lead to permanent damage. Once the installation is complete, the device will typically reboot automatically.
After rebooting, configure the basic settings, including pool details, worker credentials, and initial power limits. Many custom firmware options feature auto-tuning tools that help balance hashrate and energy efficiency. Enable these tools as a starting point, then fine-tune settings as needed.
For voltage and frequency adjustments, proceed cautiously. Custom firmware often allows you to tweak settings on a per-chip or per-board basis, so make gradual changes while closely monitoring stability. Similarly, adjust fan curves to optimize cooling, particularly if you plan to overclock your rig.
Tracking and Adjusting Performance
Once the firmware is installed and your rig is optimized, ongoing monitoring is essential to maintain performance. Keep an eye on key metrics such as hashrate (in TH/s), power consumption (in watts), energy efficiency (in J/TH), temperatures (chip and board), and fan speeds (in RPM). Most custom firmware includes real-time dashboards to help you track these metrics.
Temperature management is especially critical. Follow your hardware manufacturer’s recommendations for safe temperature ranges. If your rig runs too hot, reduce overclocking settings or improve your cooling system.
Monitor performance regularly. Use your dashboard to spot trends in hashrate and power usage that may indicate the need for further adjustments. Many firmware solutions also provide automated alerts for performance drops or unsafe temperature levels, allowing you to address problems quickly.
Make changes incrementally, and keep a log of each adjustment and its impact. This record will be invaluable for troubleshooting or replicating successful configurations across multiple rigs.

Measuring Performance Gains with Custom Firmware
Once you've implemented performance-enhancing techniques, it's time to measure the results. By monitoring key metrics like hashrate, power usage, and efficiency, you can assess the impact of your custom firmware.
Important Metrics to Monitor
To evaluate performance, focus on three main metrics: hashrate (TH/s), power consumption (W), and efficiency (J/TH). Efficiency is particularly important because it reflects how effectively your hardware converts energy into computational power. Another helpful metric is hashrate-per-watt, calculated by dividing your hashrate by power consumption. This ratio provides a quick snapshot of overall performance improvements.
Many custom firmware options come with built-in dashboards that display these metrics in real time. Alternatively, external mining management platforms can log and track data over time, making it easier to identify trends and measure long-term gains.
To fully understand the firmware's impact, compare your baseline performance (stock firmware) to the optimized performance achieved with custom firmware.
Stock vs. Custom Firmware Performance Comparison
The best way to assess the benefits of custom firmware is by comparing measurements taken before and after installation. Start by recording your hardware's performance using the stock firmware, then repeat the same tests after applying the custom firmware.
For example, Luxor's custom firmware for Antminer S21 Pro units demonstrated clear improvements. With the stock configuration, the miner achieved 234 TH/s at 3,510 W, resulting in an efficiency of 15.10 J/TH. In comparison, the underclocked profile provided 199.8 TH/s at 2,525 W, improving efficiency to 12.6 J/TH - an 18.67% boost in efficiency.
| Configuration | Hashrate (TH/s) | Power (W) | Efficiency (J/TH) | Gain (%) |
|---|---|---|---|---|
| Stock S21 Pro | 234 | 3,510 | 15.10 | - |
| Luxor Underclocked | 199.8 | 2,525 | 12.6 | +18.67% |
| Luxor Balanced | 230.0 | 3,293 | 13.8 | +8.85% |
Similarly, Braiins OS+ firmware has demonstrated up to 9% higher efficiency and as much as 14% more hashrate compared to stock configurations, depending on the selected tuning profile. These results highlight the potential profitability gains from firmware optimization.
When documenting your own results, include columns for metrics like hashrate, power consumption, efficiency, and percentage improvements. This format makes it easy to visualize the benefits and justify the effort invested in optimization.
Regular Testing for Ongoing Improvements
Performance optimization is not a one-and-done process. Regular testing is essential to maintain and improve efficiency over time. Factors like environmental conditions, hardware aging, and firmware updates all influence performance. Monthly testing helps you stay ahead of these changes and make adjustments when needed.
For instance, during the summer, higher temperatures might require reducing overclock settings to avoid thermal throttling, while cooler weather in winter could allow for more aggressive tuning. Similarly, fluctuations in electricity rates might shift the balance between maximizing hashrate and minimizing power consumption.
Set up automated alerts and conduct weekly manual reviews of your dashboard to identify underperforming chips or boards. Keeping detailed logs of adjustments and their outcomes can streamline troubleshooting and help replicate successful configurations across multiple rigs.
