Let’s get started!

What Is UEFI Firmware?

Before diving into the steps, it helps to understand what UEFI firmware is and why it matters for GPU changes.

UEFI is the modern replacement for the older BIOS (Basic Input/Output System). It’s a small program that runs when you turn on your computer, initializing hardware and loading your operating system. Unlike BIOS, UEFI supports larger hard drives, faster boot times, and a more user-friendly interface—often with mouse support.

One of UEFI’s key roles is managing hardware detection and configuration. This includes deciding which GPU your system uses during startup. For example, if your motherboard has an integrated GPU (built into the CPU or chipset) and you’ve installed a dedicated graphics card, UEFI must be told which one to prioritize.

If you don’t change the GPU setting in UEFI, your system might:
– Boot using the integrated GPU even with a powerful new card installed
– Fail to display anything if the monitor is plugged into the wrong port
– Experience performance issues or driver conflicts

That’s why learning how to change GPU in UEFI firmware is essential for any hardware upgrade.

Before You Begin: Preparation Steps

Changing GPU settings in UEFI is generally safe, but it’s important to prepare properly to avoid problems.

1. Check Your Hardware Compatibility

Not all motherboards support every GPU. Before installing a new graphics card, verify:
– Your motherboard has a compatible PCIe slot (usually PCIe x16)
– Your power supply can handle the GPU’s power requirements
– There’s enough physical space in your case

Check your motherboard’s manual or manufacturer website for a list of supported GPUs. Some older boards may not support newer cards, even if they fit.

2. Install the New GPU Physically

Turn off your PC and unplug it from the power source. Open the case and:
– Remove the old GPU (if present) by unscrewing it and releasing the PCIe latch
– Insert the new GPU into the primary PCIe x16 slot
– Secure it with screws
– Connect the required power cables from your PSU

Make sure the GPU is seated firmly and all connections are tight.

3. Connect Your Monitor to the Correct Port

This is a common mistake. After installing a new GPU, your monitor should be plugged into the video output on the graphics card—not the motherboard.

For example:
– If you’re using a dedicated GPU, plug the HDMI or DisplayPort cable into the GPU
– If you’re using the integrated GPU, plug it into the motherboard

Using the wrong port can result in a black screen, even if everything else is set up correctly.

4. Gather Necessary Tools and Information

You’ll need:
– A keyboard (some UEFI interfaces don’t support mice)
– Your motherboard manual (to find the correct boot key)
– A stable power source

Also, note your current GPU model and the new one you’re installing. This helps with driver updates later.

Step-by-Step: How to Change GPU in UEFI Firmware

Now that you’re prepared, let’s walk through the actual process of changing the GPU in UEFI.

Step 1: Access UEFI Firmware

To enter UEFI, you need to press a specific key during startup. This key varies by manufacturer:

• ASUS: Del or F2
• MSI: Del
• Gigabyte: Del or F2
• ASRock: F2 or Del
• Dell: F2
• HP: F10 or Esc
• Lenovo: F1 or F2

Turn on your PC and immediately start pressing the correct key repeatedly—don’t hold it down. You usually have only a few seconds to enter UEFI before the OS starts loading.

If you miss it, restart and try again.

Step 2: Navigate to Display or Graphics Settings

Once inside UEFI, use the arrow keys to navigate. Look for a tab or menu labeled:
– “Advanced”
– “System Configuration”
– “Boot”
– “Peripherals”
– “Graphics Configuration”
– “Primary Display”

The exact name depends on your motherboard. For example:
– On ASUS boards, go to Advanced > System Agent Configuration > Graphics Configuration
– On MSI, check Settings > Advanced > Integrated Graphics Configuration
– On Gigabyte, look under Settings > Platform Settings > Primary Display

Step 3: Change the Primary GPU Setting

In the graphics or display menu, you’ll see an option like:
– “Primary Display”
– “Initiate Graphic Adapter”
– “PEG/PCIe Graphics”
– “Integrated Graphics”

You’ll typically have these choices:
– Auto: Lets the system decide (may not always pick the right GPU)
– PCIe/PEG: Prioritizes the dedicated GPU in the PCIe slot
– IGD (Integrated Graphics Device): Uses the CPU or motherboard GPU
– Switchable: Allows dynamic switching (common on laptops)

To use your new dedicated GPU, select PCIe or PEG.

If you’re using the integrated GPU (e.g., for a lightweight build or troubleshooting), choose IGD.

Step 4: Save and Exit

After making your change:
– Press F10 (common save key) or navigate to “Save & Exit”
– Confirm by selecting “Yes” or “OK”
– The system will restart

Your PC should now boot using the selected GPU.

Step 5: Verify the GPU Is Working

Once Windows (or your OS) loads:
– Open the Start menu and search for “Device Manager”
– Expand “Display adapters”
– You should see your new GPU listed (e.g., “NVIDIA GeForce RTX 3060” or “AMD Radeon RX 6700 XT”)

If you see the correct GPU, the change was successful.

You can also check performance using tools like:
– GPU-Z (free utility)
– Task Manager (Performance tab)
– DirectX Diagnostic Tool (type “dxdiag” in Run)

Updating GPU Drivers After the Change

Changing the GPU in UEFI is only half the job. To get the best performance and avoid bugs, you must install the latest drivers.

1. Uninstall Old Drivers (Optional but Recommended)

If you’re switching from NVIDIA to AMD (or vice versa), old drivers can cause conflicts.

Use a tool like:
– DDU (Display Driver Uninstaller) – free and highly effective
– Windows’ built-in “Add or remove programs”

Boot into Safe Mode for a clean uninstall.

2. Download the Latest Drivers

Go to the official website:
– NVIDIA: https://www.nvidia.com/Download/index.aspx
– AMD: https://www.amd.com/en/support
– Intel: https://www.intel.com/content/www/us/en/download-center/home.html

Select your GPU model and operating system, then download the driver.

3. Install the New Drivers

Run the installer and follow the prompts. Choose “Custom” installation if you want to avoid bloatware (like GeForce Experience or AMD Adrenalin extras).

After installation, restart your PC.

4. Test Performance

Run a game or benchmark tool (like 3DMark or Unigine Heaven) to ensure your GPU is performing as expected.

Troubleshooting Common Issues

Even with careful preparation, problems can occur. Here’s how to fix the most common ones.

Black Screen After GPU Change

If your monitor shows “No Signal” after changing the GPU:
– Check cable connections: Ensure the monitor is plugged into the GPU, not the motherboard
– Try a different cable or port: HDMI, DisplayPort, or DVI
– Reset UEFI to defaults: Enter UEFI and select “Load Optimized Defaults”
– Test with another monitor: Rule out display hardware issues

System Fails to Boot

If your PC won’t start after the change:
– Clear CMOS: This resets UEFI settings. Locate the CMOS battery on the motherboard, remove it for 5 minutes, then reinsert
– Re-seat the GPU: Power off, remove the card, and reinstall it firmly
– Try booting with minimal hardware: Disconnect extra drives, RAM sticks, and peripherals

GPU Not Detected in Windows

If Device Manager shows “Microsoft Basic Display Adapter” or nothing at all:
– Update drivers manually: Right-click the unknown device and select “Update driver”
– Check BIOS version: Older UEFI versions may not support newer GPUs. Visit your motherboard manufacturer’s site to download and flash the latest BIOS
– Ensure Secure Boot is off: Some custom drivers require Secure Boot to be disabled

Performance Is Lower Than Expected

If your new GPU isn’t delivering the expected frame rates:
– Check power settings: In Windows, set power plan to “High performance”
– Enable Resizable BAR (if supported): This feature in UEFI can boost performance on newer GPUs
– Update motherboard chipset drivers: These affect how the CPU and GPU communicate

Tips for a Smooth GPU Upgrade

To make the process even easier, keep these tips in mind:

• Label your cables: Before disconnecting anything, take a photo or label power and data cables
• Work in a static-free area: Use an anti-static wrist strap or touch a metal object before handling components
• Keep your old GPU: In case you need to revert, having the original card is helpful
• Document your settings: Take screenshots of your UEFI settings before making changes
• Backup important data: While rare, hardware changes can sometimes cause system instability
