Troubleshooting
- eGPU Not Detected: Ensure the Oculink or USB4 cable is securely connected to both the Mini PC and the eGPU dock. Verify that the eGPU dock is receiving power. Check your operating system's device manager to see if the graphics card is recognized.
- No Display Output: Confirm that your monitor is connected to the correct HDMI or DisplayPort on the eGPU dock. Try different cables or ports. Ensure the Mini PC's internal display is disabled when using the eGPU for optimal performance.
- Performance Issues: Ensure all drivers for the AMD Radeon 7600M XT are up to date. Check the power mode settings of your Mini PC (refer to Maintenance section). For CPU-intensive games, the eGPU may not provide a significant performance boost if the CPU is the bottleneck.
- Compatibility with Apple Silicon Macs: The AD-GP1 eGPU Dock is not compatible with Apple Silicon Macs (e.g., M1, M2, M3 series). It is designed to work with Windows PCs that have USB4 or Oculink ports. Older Intel-based Macs with Thunderbolt ports might be compatible, but verify specific model support.
