How to Find Out Which Motherboard You Have

Knowing your motherboard model is one of those things that suddenly becomes urgent — you're upgrading RAM, installing a new CPU, checking driver compatibility, or troubleshooting a crash. The good news: your system already knows the answer. You just need to know where to look.

Why Your Motherboard Model Matters

The motherboard (also called the mainboard or system board) is the central circuit board connecting every component in your PC — CPU, RAM, storage, GPU, and more. Its model determines:

  • Which CPU socket is supported (and therefore which processors are compatible)
  • How many and what type of RAM slots are available
  • What expansion slots (PCIe, M.2) are present
  • Which BIOS/UEFI firmware updates apply to your system
  • Driver packages you need for chipset, audio, and networking

Getting this wrong means downloading the wrong drivers, buying incompatible hardware, or missing a critical firmware update.

Method 1: Check via Command Prompt (Windows) 🖥️

This is the fastest method for most Windows users and requires no extra software.

  1. Press Windows + R, type cmd, and hit Enter
  2. In the Command Prompt window, type the following and press Enter:
wmic baseboard get product, manufacturer, version, serialnumber 

You'll get output like:

Manufacturer Product SerialNumber Version ASUSTeK PRIME B550-PLUS Default string PRIME B550-PLUS 

The Product field is your motherboard model. The Manufacturer tells you the brand. This works on Windows 10 and Windows 11 without installing anything.

Alternative command using System Information:

  1. Press Windows + R, type msinfo32, press Enter
  2. Under System Summary, look for BaseBoard Manufacturer, BaseBoard Product, and BaseBoard Version

Same information, just presented in a GUI rather than the terminal.

Method 2: Use CPU-Z (Free Third-Party Tool)

CPU-Z is a widely used, free system information utility that reads hardware data directly from your components. After downloading and running it:

  1. Open CPU-Z and click the Mainboard tab
  2. You'll see the manufacturer, model, chipset, BIOS version, and revision

This is useful if the WMIC command returns blank or generic values — which can happen on some pre-built systems where manufacturers strip out that data.

Method 3: Check Physically Inside the Case

If software methods aren't giving you clear results, the board itself always has the answer. Power down, unplug, and open your case. The model name is printed directly on the motherboard — usually near the RAM slots or along the edge of the board in large text. Common placements:

  • Between the RAM and the PCIe x16 slot
  • Along the bottom edge of the board
  • Near the CPU socket

You're looking for something like ROG STRIX B650-E, MSI MAG Z790 TOMAHAWK, or GIGABYTE B450M DS3H. Take a photo for reference before closing the case.

Method 4: Check Your Original Documentation or Purchase History

If you built your own PC or still have the box, the model is printed on the retail packaging and included manual. For pre-built systems (Dell, HP, Lenovo, etc.), check:

  • The service tag or product ID sticker on the outside of the case
  • The manufacturer's support website using your serial number
  • Your original order confirmation or receipt

Pre-built manufacturers sometimes use proprietary OEM motherboards that aren't sold separately — meaning the board has a generic internal name rather than a consumer product name. In those cases, the system model number matters more than the board model.

Method 5: BIOS/UEFI Screen

When your PC boots, you can press a key (usually Delete, F2, or F10 depending on the brand) to enter the BIOS or UEFI interface. The motherboard model is almost always displayed on the main screen or in the system information section.

This method is useful if Windows isn't booting correctly and you need the board info for troubleshooting or driver recovery.

What the Model Number Actually Tells You 🔍

Once you have the model, the naming convention carries real information:

  • Chipset tier: Budget boards often use B-series chipsets (B550, B650, B760), while enthusiast boards use Z-series (Z790) or X-series (X670)
  • Form factor: ATX, Micro-ATX, and Mini-ITX affect case compatibility and expansion slot count
  • Generation: The number in the chipset name typically corresponds to compatible CPU generations — though this varies by manufacturer

A B550 board supports AM4-socket Ryzen CPUs but not AM5. A Z790 board supports Intel's LGA1700 socket. These distinctions matter immediately when you're planning an upgrade.

When Results Are Blank or Generic

Some OEM and pre-built systems return values like "Default String" or "To Be Filled By O.E.M." in WMIC output. This is a BIOS configuration choice made during manufacturing — it doesn't mean the data doesn't exist. In those cases, physical inspection or checking the manufacturer's support portal using your system's serial number will get you to the actual board specifications.


The method that works best depends on your situation — whether you're running a custom-built PC, a major-brand desktop, or a system that won't fully boot. Each path leads to the same answer, but what you do with that model number next depends entirely on why you needed it in the first place.
