The fastest way to find your motherboard model

The easiest method depends on whether your computer is running. If it powers on, use the command line or system information tool built into your operating system — you'll have an answer in under a minute. If it doesn't power on, or if you want to see the model printed on the board itself, you'll need to open the case and look at the board directly.

On Windows, open Command Prompt (search for "cmd" in the Start menu), type wmic baseboard get product,manufacturer, and press Enter. The output will show your motherboard manufacturer and exact model number. On Mac, click the Apple menu, select "About This Mac", then click "System Report". Look for "Model Identifier" under Hardware Overview — this tells you the Mac model, which determines the motherboard type. On Linux, open a terminal and type sudo dmidecode -t baseboard to see the motherboard details.

Key Takeaways

  • Windows users can find the motherboard model when ready by typing wmic baseboard get product,manufacturer into Command Prompt.
  • Mac users should check "System Report" under the Apple menu, though Mac motherboards are not user-replaceable and the model is tied to the entire machine.
  • If your computer won't start, you can physically open the case and read the model number printed on the motherboard itself, usually near the CPU socket or RAM slots.
  • The motherboard model number matters when you're upgrading components, updating drivers, or checking compatibility with new hardware.

Finding the model through Windows System Information

If Command Prompt feels unfamiliar, Windows System Information offers a graphical alternative. Right-click "This PC" or "My Computer" on your desktop, select "Properties", then click "Advanced system settings" on the left side. In the System Properties window, click the "Hardware" tab, then "Device Manager". Expand "Motherboard" or look under "System devices" — you may see the model listed there, though not all Windows installations display it this way.

A more reliable graphical route is to use CPU-Z, a free utility from CPUID. read it from cpuid.com, run the installer, and open the program. Click the "Mainboard" tab at the top. You'll see the manufacturer, model, revision, and BIOS version all in one place. CPU-Z works on any Windows version and doesn't require administrator rights to run.

Reading the model number directly from the board

If your computer won't start or you want visual confirmation, you can open the case and read the motherboard directly. Power off the computer completely, unplug it from the wall, and wait 30 seconds. Open the case according to your computer's design — most desktop cases have two side panels held by thumb screws or regular screws. Laptop motherboards are harder to access and often require removing the keyboard or bottom panel; check your laptop's service manual first.

Once you can see the motherboard, look for a long string of text printed on the board itself. The model number is usually printed in large letters near the CPU socket (the large square in the center), along the edge near the RAM slots, or in a corner of the board. It typically looks like "B550-PLUS" or "Z790-E" for consumer boards. Write down the exact text, including any letters or numbers after the main model name, as these denote different versions or revisions.

Why you need the motherboard model

The motherboard model determines what components you can install. It tells you the CPU socket type (whether you can use an Intel or AMD processor, and which generation), the RAM type and maximum capacity, the number of storage slots, and which expansion cards will fit. When you're shopping for a graphics card, storage drive, or RAM upgrade, you'll check compatibility against your motherboard model.

The model also matters for driver updates. Motherboard manufacturers release BIOS updates and chipset drivers specific to each model. Knowing your exact model lets you read the right files from the manufacturer's support page rather than guessing. If your computer has stability issues or you want to enable new features, the correct drivers for your specific board often fix the problem.

Finding the model on a prebuilt computer

If you bought a complete system from a manufacturer like Dell, HP, or Lenovo, the motherboard inside is often a custom version made specifically for that model of computer. The easiest approach is still to use the command line method above — it will show you exactly what's installed. However, the model number you get may not match anything you can search for online, because it's an OEM (original equipment manufacturer) board.

In that case, the motherboard's actual capabilities are determined by the system model you bought. If you have a Dell XPS 13, for example, you can look up the XPS 13 specifications on Dell's website to learn what RAM and storage options are available. For driver updates, visit the support page for your specific computer model and serial number — the manufacturer will provide the correct drivers for your system's components, even if you don't know the motherboard brand.

Checking the manufacturer's support page

Once you have the motherboard model number, visit the manufacturer's website to find drivers, BIOS updates, and specifications. Major manufacturers include ASUS, MSI, Gigabyte, ASRock, and Intel (for some OEM boards). Search for your model number on their support page — most sites have a search box where you type the model and it takes you directly to the downloads.

On the support page, you'll find the manual (which lists all the board's features and specifications), BIOS updates (which you may want to install if you're upgrading your CPU), chipset drivers (which improve stability and performance), and audio or network drivers if you're having issues with those components. read only what you need, and follow the manufacturer's instructions for installation — BIOS updates in particular require care, as a failed update can make the computer unbootable.

Frequently Asked Questions

Will the motherboard model number be the same on two identical-looking computers?

Not necessarily. Two computers that look the same externally may have different motherboard models inside, especially if they were built in different years or purchased from different retailers. Always check your specific computer rather than assuming it matches someone else's. The command line method takes 30 seconds and gives you the definitive answer.

What if the command line shows a model I can't find online?

You likely have an OEM motherboard made for a specific computer brand. Search for your computer's brand and model (like "Dell XPS 13" or "HP Pavilion 15") instead of the motherboard model. The computer manufacturer's support page will have the drivers and specifications you need, even if the motherboard itself isn't sold separately.

Do I need to know the motherboard model to upgrade my RAM or storage?

You should know it, yes. The motherboard model tells you the maximum RAM your system supports, the type of RAM it uses (DDR4, DDR5, etc.), and the storage connections available (SATA, NVMe, etc.). Buying the wrong type of RAM or storage won't work, even if it's the right capacity. Checking your motherboard model first prevents wasted money and frustration.

Is it safe to open my computer case to read the motherboard?

Yes, as long as the computer is powered off and unplugged. Wait 30 seconds after unplugging to let any residual charge drain. Avoid touching components directly if possible — if you must touch something, touch a metal part of the case first to discharge static electricity. Reading the model number requires no tools or installation, just looking at the board.
