How to Test RAM on Windows 11

In the following steps, you’ll learn how to use the Windows Memory Diagnostic tool to test your RAM. This tool will help you identify and fix any problems with your computer’s memory.

Step 1: Open the Windows Memory Diagnostic Tool

To start, press the Windows key on your keyboard, type "Windows Memory Diagnostic," and hit Enter.

This will bring up the Windows Memory Diagnostic tool. It’s an easy-to-use utility that comes built-in with Windows 11, no need for any additional downloads.

Step 2: Choose Restart Now and Check for Problems

Click "Restart now and check for problems (recommended)."

Your computer will restart and the diagnostic tool will automatically begin scanning your RAM. This process can take several minutes, so be patient.

Step 3: Let the Scan Complete

Wait for the memory test to complete. This might take some time.

The diagnostic tool will check your RAM modules for errors. If it finds any issues, it will report them after the scan is done. Look for any displayed error messages or issues.

Step 4: Review the Results

Once the test is complete, your computer will boot back into Windows. You’ll see the test results after logging in.

If the diagnostic tool reports any errors, consider replacing your RAM or consulting a professional for further assistance.

Faulty RAM can cause a range of problems, from system crashes to data corruption. Addressing any errors promptly can prevent more serious issues down the line.

After completing these steps, your computer will reboot and display test results, either confirming your RAM is in good condition or highlighting any problems that need addressing.
