Find Your Motherboard Model Without Opening Your PC

You can identify your motherboard without cracking open your case. Windows and Mac both store this information in system settings and command-line tools that take less than a minute to access. The fastest route on Windows is the System Information window; on Mac, it's the About This Mac menu. Both methods show you the exact model number, manufacturer, and often the BIOS version — everything you need if you're troubleshooting, updating drivers, or checking compatibility before buying new hardware.

The information you find here is the same as what you'd see printed on the physical board itself. You don't need any special software or administrator permissions, though you may need to restart your computer to explore changes after you've identified a problem.

Key Takeaways

  • On Windows, open System Information by pressing Windows key + R, typing "msinfo32", and pressing Enter to see your motherboard model when ready.
  • On Mac, click the Apple menu, select About This Mac, and look under System Report to find your logic board model and serial number.
  • Command Prompt on Windows and Terminal on Mac can show additional details like BIOS version and chipset if the graphical menus don't display everything you need.
  • If System Information shows "System manufacturer: Unknown" or "System model: Unknown", your PC was likely built from individual parts and you'll need to check the BIOS instead.
  • Write down your motherboard model number before you search for drivers or compatibility information, since manufacturers often use similar names for different revisions.

Check Your Motherboard on Windows Using System Information

Open the Run dialog by pressing Windows key + R on your keyboard. Type msinfo32 and press Enter. The System Information window will open in about two seconds.

Look for these fields in the main panel on the right side: System Manufacturer (the company that made your PC, like Dell or HP) and System Model (the specific model number). If you built your PC from parts, these fields may say "Unknown" — in that case, skip to the BIOS method below. If they show a real manufacturer and model, you've found what you need. Write down both the manufacturer and model number exactly as they appear.

Scroll down in the same window to find BIOS Version/Date if you need to know whether your BIOS is current. This information is useful if you're updating drivers or troubleshooting hardware conflicts.

Check Your Motherboard on Mac Using About This Mac

Click the Apple menu in the top-left corner of your screen and select About This Mac. A window will open showing your Mac model and serial number at the top.

Click the System Report button at the bottom of that window. A new window opens with more detailed information. On the left side, make sure Hardware is selected. Look for the field labeled Model Identifier — this is the internal name Apple uses for your logic board. You'll also see Serial Number, which is unique to your machine.

If you need the physical board's revision or chipset details, scroll down to find Board ID and Boot ROM Version. These details are less commonly needed but useful if you're contacting Apple Support or checking compatibility with third-party upgrades.

Find Your Motherboard in the BIOS if System Information Shows Unknown

If Windows System Information displayed "Unknown" for both manufacturer and model, your PC was assembled from individual components and the motherboard model is stored in the BIOS, not in Windows. Restart your computer and watch the screen carefully as it boots. You'll see a message that says something like "Press DEL to enter Setup" or "Press F2 to enter BIOS" — the key varies by motherboard manufacturer.

Press that key repeatedly as soon as you see the message. You'll enter the BIOS setup screen, which looks different from Windows — it's usually blue or black with white text. Look for a menu item called Main, System Information, or Board Information. Click or navigate to it using your arrow keys. The motherboard model and manufacturer will be displayed there, often labeled as Board Name or System Model.

Write down the exact model name, then press Escape or look for an Exit option to leave the BIOS without saving changes. Your computer will boot normally into Windows.

Use Command Prompt for Detailed Motherboard Information

If you want more technical details than System Information provides, Command Prompt can pull additional data. Press Windows key + R, type cmd, and press Enter. A black window with white text will open.

Type this command exactly: wmic baseboard get product,manufacturer,version,serialnumber and press Enter. Command Prompt will display your motherboard's product name, manufacturer, version number, and serial number in a table format. This method works even on older Windows versions and often shows information that the graphical System Information window doesn't display.

If you need BIOS details, type wmic bios get smbiosbiosversion and press Enter. This shows your BIOS version number, which is useful if you're checking whether a BIOS update is available for your board.

Use Terminal on Mac for Advanced Details

Open Terminal by pressing Command + Space, typing "terminal", and pressing Enter. A text window will open. Type this command: system_profiler SPHardwareDataType and press Enter. Terminal will display detailed hardware information including your logic board model, serial number, and memory configuration.

For even more specific motherboard details, type ioreg -l | grep -i "board-id" and press Enter. This pulls the board ID directly from your system registry. The output will show a long string of characters — that's your board's unique identifier, which is sometimes needed for compatibility checks or warranty service.

What to Do With Your Motherboard Information

Once you have your motherboard model number, you can use it to search for driver updates, check hardware compatibility, or find the manual. Visit the manufacturer's support website (Dell, HP, Asus, Gigabyte, MSI, etc.) and search for your exact model number. Most manufacturers organize downloads by model, so entering the correct number saves time and prevents you from downloading drivers for the wrong board.

If you're buying new RAM, storage, or other components, search your motherboard model on the manufacturer's website to find the compatibility list. Some older boards don't support newer memory types or have limits on how much RAM they can use. Checking this before you buy prevents wasted money and frustration.

Keep your motherboard model number and BIOS version in a text file or notebook. If you ever need to contact technical support or troubleshoot a hardware problem, having this information ready saves time and helps the support person understand your setup faster.

Frequently Asked Questions

Why does my System Information say "Unknown" for the motherboard?

This happens when your PC was built from individual parts rather than purchased as a complete unit from a manufacturer like Dell or HP. Windows doesn't automatically detect custom-built motherboards. Use the BIOS method instead: restart your computer, press the BIOS key (usually DEL or F2) during startup, and look for the board name in the Main or System Information menu.

Is it safe to enter the BIOS to check my motherboard?

Yes, as long as you don't change any settings. Just look at the information and press Escape or Exit to leave without saving. The BIOS is read-only unless you actively press a Save button, so browsing it won't harm your computer.

What's the difference between motherboard model and BIOS version?

The motherboard model is the physical board itself — like "ASUS ROG Strix B550-F". The BIOS version is the firmware running on that board, like "3204". You need the model number to find drivers and manuals; you need the BIOS version to check if updates are available.

Can I check my motherboard information on a Mac without opening System Report?

Yes, use Terminal. Press Command + Space, type "terminal", and run the command system_profiler SPHardwareDataType. It displays the same information as System Report but in text format, which some people find faster to read.

Do I need to restart my computer to check the motherboard?

No, unless you're using the BIOS method. System Information, About This Mac, and Command Prompt or Terminal all work while your computer is running normally.
