Troubleshoot Memory with Windows Memory Diagnostic

Windows Memory Diagnostic is a built-in Windows system tool designed to detect physical memory hardware issues; when encountering blue screens related to memory management like MEMORY_MANAGEMENT, you can use it to troubleshoot hardware problems.

How It Works

The tool operates on a simple principle:

• Write Data: It writes a series of specific data patterns to every address in physical memory;
• Verify Data: It then reads data from these addresses and compares it with the originally written data;
• Detect Errors: If data doesn't match, it indicates physical defects in that memory address area, making it unable to reliably store data;

This process repeats in multiple different modes to ensure comprehensive detection of potential issues.

Running Windows Memory Diagnostic

Use the shortcut + R to open the [Run] dialog, enter mdsched.exe and confirm;

After restarting, the detection will begin automatically. The entire process may take several tens of minutes, or even hours, depending on memory size and speed; no interaction is required during this period, just wait.

After completion, the system will automatically restart and boot into Windows.

Viewing Memory Diagnostic Results

After entering the system, a Windows Memory Diagnostic message typically pops up - click to view results; if no message appears, manual checking is required;

Use the shortcut + R to open the [Run] dialog, enter eventvwr.msc and confirm;

In Event Viewer's left panel, expand [Windows Logs] → [System];

Then click [Find...] in the right panel, enter MemoryDiagnostics-Results in the search box;

Close the dialog, the corresponding event will be selected in the middle list - double-click to open;

Results typically come in two types:

• Windows Memory Diagnostic tested the computer's memory and detected no errors;

• Windows Memory Diagnostic detected hardware problems with the computer's memory;

  This indicates physical defects in the RAM modules;
