Discover Your RAM Type with Simple Windows Commands

Most modern PCs utilize DDR RAM, with variations including DDR3, DDR4, and the latest DDR5. To find out which type your system has, you can use a straightforward command in Windows:

  1. Open the Command Prompt as Administrator: Right-click the Start button and select “Terminal (Administrator)”.
  2. Type the Command to Reveal RAM Type: Enter wmic memorychip get SMBIOSMemoryType into the terminal. This command will return a numeric code indicating your RAM type:
    • 20 indicates DDR
    • 21 means DDR2
    • 24 signifies DDR3
    • 26 shows that you have DDR4
    • 34 tells you it’s DDR5

These values help identify not only the generation of DDR RAM but also ensure compatibility when purchasing additional memory.

Checking RAM Speed

Understanding the speed of your RAM is also beneficial, particularly if you aim to match or optimize your system’s performance:

  • Enter the Command for Speed: Type wmic memorychip get speed in the same terminal window.
  • This command will display the speed of your RAM modules in MHz, such as 6000 MHz, which is crucial for ensuring that any additional RAM matches this speed for optimal performance.
