DaVinci Resolve GPU Not Detected: Troubleshooting Guide
Experiencing the dreaded "GPU not detected" error in DaVinci Resolve can be incredibly frustrating, especially when deadlines loom. This issue can stem from various causes, ranging from outdated drivers to insufficient power. This guide provides a structured approach to diagnosing and resolving the problem.
Initial Checks and Quick Fixes
Before diving into more complex solutions, start with these fundamental checks:
- Restart Resolve and Your Computer: This simple step often resolves temporary glitches.
- Verify Minimum System Requirements: DaVinci Resolve 18.5, for example, requires a minimum of 2GB of GPU memory, and a dedicated GPU from NVIDIA, AMD, or Intel (with appropriate drivers). Check the official Blackmagic Design website for the exact requirements for your version.
- Check Power Supply: Ensure your power supply unit (PSU) provides sufficient wattage for your GPU. Insufficient power can lead to instability and detection issues. A 650W PSU is often recommended for mid-range GPUs, while high-end cards may require 750W or more.
- Physical Connection: Make sure the GPU is securely seated in its PCI-e slot. Reseat the card if necessary. Also, check the power connectors going to the GPU.
Advanced Troubleshooting Steps
If the basic checks don't resolve the issue, proceed with these more advanced troubleshooting steps:
- Update Your GPU Drivers: Outdated drivers are a common culprit. Download the latest drivers from the NVIDIA, AMD, or Intel website (depending on your GPU) and perform a clean installation. During the installation process, choose the "Custom (Advanced)" option and select "Perform a clean installation" to remove any remnants of previous drivers.
- DaVinci Resolve Configuration: Open DaVinci Resolve and navigate to DaVinci Resolve > Preferences > Memory and GPU. Ensure that your GPU is selected under "GPU Processing Mode." Try switching between CUDA, OpenCL, and Metal to see if one works better. Also, check the "Auto" option.
- CUDA Driver Version (NVIDIA Only): If using an NVIDIA GPU, ensure your CUDA driver version is compatible with your DaVinci Resolve version. Blackmagic Design often publishes recommendations for CUDA driver versions.
- Check the DaVinci Resolve Logs: The logs can provide valuable clues. Look for error messages related to GPU detection. The logs are typically located in the DaVinci Resolve application folder.
- Disable Other GPUs (If Applicable): If you have multiple GPUs, try disabling the integrated GPU in your BIOS settings to force DaVinci Resolve to use the dedicated card.
By systematically working through these steps, you should be able to identify and resolve the "GPU not detected" error in DaVinci Resolve and get back to editing.
