Bitaxe Hashrate Benchmark

A Python-based benchmarking tool for optimizing Bitaxe mining performance by testing different voltage and frequency combinations while monitoring hashrate, temperature, and power efficiency.

Features

• Automated benchmarking of different voltage/frequency combinations
• Temperature monitoring and safety cutoffs
• Power efficiency calculations (J/TH)
• Automatic saving of benchmark results
• Graceful shutdown with best settings retention
• Docker support for easy deployment

Prerequisites

• Python 3.11 or higher
• Access to a Bitaxe miner on your network
• Docker (optional, for containerized deployment)

Installation

Standard Installation

1. Clone the repository:

git clone https://github.com/mrv777/Bitaxe-Hashrate-Benchmark.git
cd Bitaxe-Hashrate-Benchmark

2. Create and activate a virtual environment:

python -m venv venv
# On Windows
venv\Scripts\activate
# On Linux/Mac
source venv/bin/activate

3. Install dependencies:

pip install -r requirements.txt

Docker Installation

1. Build the Docker image:

docker build -t bitaxe-benchmark .

Usage

Standard Usage

Run the benchmark tool by providing your Bitaxe's IP address:

python bitaxe_hashrate_benchmark.py <bitaxe_ip>

Optional parameters:

• -v, --voltage: Initial voltage in mV (default: 1150)
• -f, --frequency: Initial frequency in MHz (default: 500)

Example:

python bitaxe_hashrate_benchmark.py 192.168.2.26 -v 1200 -f 550

Docker Usage

Run the container with your Bitaxe's IP address:

docker run --rm bitaxe-benchmark <bitaxe_ip> [options]

Example:

docker run --rm bitaxe-benchmark 192.168.2.26 -v 1200 -f 550

Configuration

The script includes several configurable parameters:

• Maximum chip temperature: 66°C
• Maximum VR temperature: 90°C
• Maximum allowed voltage: 1400mV
• Maximum allowed frequency: 1200MHz
• Benchmark duration: 20 minutes
• Sample interval: 30 seconds
• Voltage increment: 25mV
• Frequency increment: 25MHz

Output

The benchmark results are saved to bitaxe_benchmark_results.json, containing:

• Complete test results for all combinations
• Top 5 performing configurations ranked by hashrate
• For each configuration:
  • Average hashrate
  • Temperature readings
  • Power efficiency metrics (J/TH)
  • Voltage/frequency combinations tested

Safety Features

• Automatic temperature monitoring with safety cutoff (66°C chip temp)
• Voltage regulator (VR) temperature monitoring with safety cutoff (90°C)
• Graceful shutdown on interruption (Ctrl+C)
• Automatic reset to best performing settings after benchmarking
• Input validation for safe voltage and frequency ranges
• Hashrate validation to ensure stability

Benchmarking Process

The tool follows this process:

1. Starts with user-specified or default voltage/frequency
2. Tests each combination for 20 minutes
3. Validates hashrate is within 8% of theoretical maximum
4. Incrementally adjusts settings:
   • Increases frequency if stable
   • Increases voltage if unstable
   • Stops at thermal or stability limits
5. Records and ranks all successful configurations
6. Automatically applies the best performing stable settings
