How to use the dedicated GPU?

Hello Luca Galiano

Welcome to the Microsoft Community.

Let’s troubleshoot this step-by-step. Your HP laptop with dual AMD GPUs (Radeon R7 integrated + Radeon R7 M340 dedicated) likely requires a combination of driver, software, and hardware configuration adjustments. Here’s how to resolve this:

1. Update or Reinstall GPU Drivers

• Uninstall Conflicting Drivers:
  1. Download AMD Cleanup Utility
  2. Boot into Safe Mode (hold Shift while clicking "Restart" in Windows).
  3. Run the utility to remove both AMD integrated and dedicated GPU drivers.
  4. Restart your laptop.
• Reinstall Drivers:
  1. Visit AMD’s official website and use the Auto-Detect Tool to install the latest drivers for both GPUs.
  2. Ensure the dedicated GPU (R7 M340) is recognized in Device Manager under Display adapters.

Watch out for ads on the site that may advertise products frequently classified as PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it. 

2. Configure AMD Radeon Software

• Open AMD Radeon Settings (right-click desktop > AMD Radeon Software).
• Navigate to System > Switchable Graphics.
• For specific apps/games, set them to High Performance (dedicated GPU). If this option is missing, proceed below.

3. Force Dedicated GPU via Windows Graphics Settings

1. Go to Settings > System > Display > Graphics settings.
2. Add your app/game's primary executable program and select High performance (R7 M340).
   Note: Some apps may not appear here; use the "Desktop app" dropdown to browse.

4. Check Power Settings

• Windows Power Plan:
  1. Open Control Panel > Hardware and Sound > Power Options.
  2. Select High performance (not "Balanced" or "Power Saver").
• AMD Power Settings:
  • In Radeon Software, go to System > Graphics > Global Graphics and disable Battery Boost or Power-Saving modes.

5. BIOS/UEFI Configuration

• Re-enter BIOS.
• Look for options like:
  • Switchable Graphics → Set to Dynamic or Fixed (disable "Auto" if possible).
  • Primary Graphics Adapter → Force PCIe/Discrete GPU.
  • Save changes and exit.
• Update BIOS if options are missing (download from HP Support).

6. Check for Hardware Limitations

• Some HP laptops disable the dedicated GPU when on battery power. Plug in the charger and test again.
• Overheating or hardware failure can disable the GPU. Use HP Hardware Diagnostics (press F2 during boot) to test the GPU.

7. Verify GPU Activity

• Use Task Manager (Ctrl+Shift+Esc) > Performance tab to see which GPU is active during tasks.
• Consider some third-party tools, for example GPU-Z to monitor dedicated GPU usage.

8. Contact HP Support

If all else fails:

• Your laptop’s BIOS/UEFI may permanently disable the dedicated GPU due to firmware limitations.
• HP’s design might prioritize the integrated GPU for power efficiency. Check their forums or support for model-specific fixes.

Let me know if the dedicated GPU still isn’t detected after these steps. We can dig deeper into logs or hardware checks!

in the AMD software i tried to see the switchable graphics but there isn't that

setting, and in the Graphics settings it gives me only the integrated GPU.
