GPU Troubleshooting

Solutions for GPU acceleration problems.

​
GPU Not Detected

​
Check NVIDIA Drivers

# Windows (PowerShell)
nvidia-smi

# Linux
nvidia-smi
If this command fails, install or update your NVIDIA drivers.

​
Verify CUDA Installation

nvcc --version
Expected output should show CUDA 12.x or later.

​
Check cuDNN

cuDNN must be installed separately:
  1. Download from NVIDIA cuDNN
  2. Extract to your CUDA installation directory
  3. Restart Echophrase

​
GPU Detected But Not Used

  1. Open Echophrase Settings → System Info
  2. Ensure “Use GPU” is enabled
  3. Check that CUDA version matches requirements (12.0+)

​
Out of Memory Errors

If you see “CUDA out of memory”:
  1. Use a smaller model (Tiny or Base)
  2. Close other GPU-intensive applications
  3. Restart Echophrase to free GPU memory

​
Performance Issues

If GPU transcription is slow:
  1. Check GPU utilization with nvidia-smi
  2. Ensure you’re not thermal throttling
  3. Try a smaller model for faster results
