Bitweb GPU Miner v1.2.0

Bitweb GPU Miner v1.2.0 delivers a major Argon2id performance upgrade through hardware-aware GPU batch selection, while retaining the straightforward wallet-only setup and NitroPool integration introduced in earlier releases.

Supply your wallet address, select your nearest NitroPool region and choose CUDA or OpenCL. The algorithm, pool address, port and password are configured automatically.

What’s New in v1.2.0

  • Replaced the fixed 64-hash GPU batch with automatic per-GPU batch selection

  • Added architecture- and memory-aware Argon2id batch sizing for CUDA and OpenCL

  • Added independent batch sizing for multiple-GPU systems

  • Added startup reporting of each GPU’s selected batch size

  • Added the optional --gpu-batchsize=N override for manual tuning and testing

  • Improved final-batch and nonce-range handling

  • Added native CUDA builds for NVIDIA GPUs from Maxwell through Blackwell:

    • Maxwell, Pascal, Volta and Turing
    • Ampere, Ada Lovelace, Hopper and Blackwell

  • Added forward-compatible PTX for Blackwell GeForce GPUs

  • Improved CUDA performance on GPUs previously limited by the fixed batch size

Performance Validation

Testing on an NVIDIA GeForce RTX 4060 improved sustained CUDA performance from approximately 5.03 kH/s with the previous fixed batch of 64 to approximately 31.9 kH/s with the automatically selected batch of 256.

This represents approximately a 6.3× performance improvement on the tested RTX 4060.

Performance varies by GPU model, driver, backend, power limit, clock speed and cooling configuration. Automatic batch selection is recommended for normal mining.

Features

  • Dedicated Bitweb Argon2id mining
  • NVIDIA CUDA support
  • NVIDIA and AMD OpenCL support
  • Optimised CUDA and OpenCL Argon2id kernels
  • Hardware-aware automatic GPU batch selection
  • Optional manual GPU batch override
  • Automatic GPU detection
  • Multiple GPU support with independent per-device batch sizing
  • Native CUDA support from Maxwell through Blackwell
  • AU, EU and US NitroPool region selection
  • Automatic NitroPool connection configuration
  • GPU utilisation, temperature, graphics clock, power and fan telemetry
  • NVIDIA telemetry through NVML on Linux and Windows
  • AMD telemetry through amdgpu on Linux
  • AMD telemetry through ADLX on Windows
  • Five-minute Miner Report with interval and session statistics
  • Accepted, stale, rejected and block-solved share reporting
  • Improved network, Stratum, target and share-difficulty formatting
  • Portable 64-bit Linux and Windows packages
  • Bundled GPU libraries, kernels and Windows runtime dependencies
  • SHA-256 release checksums

OpenCL and CUDA performance varies between GPU models and driver versions. Test both backends to determine which performs best on your hardware.

Linux Download

Download:

bitweb-gpu-miner-linux-x64.tar.gz

Extract it:

tar -xzf bitweb-gpu-miner-linux-x64.tar.gz
cd bitweb-gpu-miner-linux-x64

Run Bitweb:

./bitweb YOUR_WALLET_ADDRESS

Linux SHA-256 Checksum

Verify:

sha256sum bitweb-gpu-miner-linux-x64.tar.gz

Windows Download

Download:

bitweb-gpu-miner-windows-x64.zip

Extract the ZIP and open PowerShell or Windows Terminal in the extracted directory.

Run Bitweb:

.\bitweb.exe YOUR_WALLET_ADDRESS

The Windows release includes the required application runtime DLLs. Visual Studio, MSYS2, the CUDA Toolkit and Microsoft Visual C++ Redistributable are not required.

For CUDA mining, install a current NVIDIA driver compatible with your GPU. Using the latest compatible driver is recommended for CUDA and OpenCL performance and stability.

Running Bitweb

Bitweb will ask you to select:

  1. NitroPool region: AU, EU or US
  2. GPU backend: CUDA or OpenCL

Bitweb automatically configures:

  • Algorithm: Argon2id
  • Pool: NitroPool
  • Port: 6236
  • Password: c=BTE
  • GPU batch: Automatic per-device selection

Automatic batch selection is recommended:

./bitweb YOUR_WALLET_ADDRESS

Advanced users can manually override the batch size for testing and tuning:

./bitweb YOUR_WALLET_ADDRESS --gpu-batchsize=512

On Windows:

.\bitweb.exe YOUR_WALLET_ADDRESS --gpu-batchsize=512

A larger batch does not always improve performance and may increase memory usage, temperature and share latency. Compare sustained hashrate and stability before selecting a manual value.

GPU Telemetry

Bitweb reports available GPU utilisation, temperature, graphics clock, power and fan information every minute.

Metric availability depends on the GPU model, driver and operating system. Unsupported values may display as N/A. Manufacturer-provided monitoring software is still recommended.

Hardware Warning

Mining places a sustained load on your GPU and can significantly increase temperature, fan speed, power consumption and component wear.

Use trusted GPU-monitoring software and ensure your hardware has adequate cooling and power capacity.

Stop mining if the GPU overheats, becomes unstable or produces errors.

Bitweb is provided as-is and without warranty. Use it entirely at your own risk. NitroPool and its contributors are not responsible for hardware damage, instability, data loss, power costs, lost earnings or other losses resulting from its use.
