Filtering for Memory Diagnostic Results

Select Event Sources: In the Filter Current Log window, click on the “Event sources” dropdown menu.
Check MemoryDiagnostics-Results: Scroll down and check the box next to “MemoryDiagnostics-Results.”
Click OK: Click the “OK” button to apply the filter.

Interpreting the Results

Review the Events: The System log will now display only events related to MemoryDiagnostics-Results. Look for events with the most recent date and time that corresponds to when you ran the memory diagnostic.
Examine the Event Details: Click on an event to view its details in the lower pane. The details will indicate whether any errors were detected during the memory test. It will usually say “The Windows Memory Diagnostic tested the computer’s memory and detected no errors” or indicate specific errors found.

Using Command Prompt to View Results

Open Command Prompt as Administrator: Press the Windows key, type “cmd,” right-click on “Command Prompt,” and select “Run as administrator.”
Execute the Command: Type the following command and press Enter: wevtutil qe System /q:"Event[System[Provider[@Name='MemoryDiagnostics-Results']]]" /f:text
Read the Output: The command will output the details of the memory diagnostic results directly in the Command Prompt window.

Understanding Common Memory Diagnostic Messages

The Memory Diagnostic tool provides different messages based on the test results.

“The Windows Memory Diagnostic tested the computer’s memory and detected no errors”: This is the ideal outcome, indicating that your RAM is functioning correctly.
Error messages with specific codes or descriptions: These messages indicate that errors were found in your RAM. Note the specific error information for further troubleshooting.

Troubleshooting Memory Errors

If the Memory Diagnostic tool detects errors, consider the following steps:

Run the test again: Sometimes, errors can be transient. Run the memory diagnostic again to confirm the results.
Test individual RAM modules: If you have multiple RAM modules, test them one at a time to identify the faulty module. Remove all but one module and run the diagnostic. Repeat this process for each module.
Replace the faulty RAM module: If you identify a faulty module, replace it with a new one.

Tips

Always run the Memory Diagnostic tool with administrator privileges to ensure it has the necessary permissions to access system logs.
If you are experiencing frequent crashes or blue screen errors, running a memory diagnostic is a good first step in troubleshooting.
Document any error messages or codes you encounter during the memory diagnostic test. This information can be helpful when seeking further assistance or troubleshooting online.
