How to Determine a CPU Socket Type

Determining the CPU socket type used by your computer is important when looking to upgrade your CPU or motherboard. The socket type must match between the CPU and the motherboard for them to be compatible. Here’s how you can determine your CPU socket type:

1. Check the Documentation

The easiest way to find the socket type is by checking the documentation that came with your motherboard or computer. The user manual or specifications sheet should list the socket type.

2. Use System Information Tools

You can use built-in system information tools or third-party applications to find out what socket your system uses.

For Windows:

  • Open “Task Manager” (Ctrl + Shift + Esc), go to the “Performance” tab, click on “CPU,” and look for the socket type in the lower-right corner (available in some Windows versions).
  • Use the “System Information” utility by opening the Run dialog (Win + R), typing msinfo32, and pressing Enter. Look for the processor model under “System Summary,” and then you can search online for that processor’s socket type.

For macOS:

  • Click on the Apple menu and select “About This Mac.”
  • Click “System Report” to open the System Information application.
  • Under “Hardware,” find the “Model Identifier” and look up this model online to find the socket type.

Third-Party Applications:

  • Use applications like CPU-Z or Speccy for Windows, which provide detailed information about your CPU including the socket type.

3. Look Up the CPU Model

Once you know the exact model of your CPU, you can search for its specifications online on the manufacturer’s website or in a CPU database. Intel and AMD, the two main CPU manufacturers, provide detailed specs for each processor model, including the socket type.

4. Visual Inspection

If you are comfortable opening your computer, you can physically look at the motherboard. Often, the socket type is printed on the motherboard next to the CPU socket. However, this should be done with caution to avoid damaging the computer components.

5. Contact the Manufacturer

If you have a pre-built computer and can’t find the documentation, you could contact the manufacturer’s customer support with your model number, and they should be able to provide you with the socket information.

Common Socket Types

As of November 2023, here are some common socket types for both Intel and AMD:


  • LGA 1151
  • LGA 1200
  • LGA 1700
  • LGA 2066


  • AM4
  • sTRX4
  • AM5 (expected to be released for future processors)


Always ensure you are grounded when touching internal components to avoid static damage. Additionally, CPU and motherboard upgrades should only be done if you are confident in handling computer hardware or by a professional.
