Types of Memory Dump Files

Windows creates different types of dump files depending on your system configuration and the nature of the crash:

Small Memory Dump (Minidump)

Small memory dumps, typically 256KB to 1MB in size, contain essential crash information including the stop error code, parameters, and a list of loaded drivers. These files are stored in C:\Windows\Minidump\ and are ideal for basic troubleshooting without consuming excessive disk space.

Kernel Memory Dump

Kernel dumps capture only kernel-mode memory, including the kernel, hardware abstraction layer (HAL), and kernel-mode drivers. These files are significantly larger than minidumps but smaller than complete dumps, typically ranging from 200MB to 2GB depending on your system's RAM.

Complete Memory Dump

Complete dumps contain the entire contents of system memory when the crash occurred. These files can be as large as your installed RAM and are stored as C:\Windows\MEMORY.DMP. While they provide the most comprehensive information, they require substantial disk space and processing time to analyze.

Automatic Memory Dump

Introduced in newer Windows versions, automatic dumps intelligently adjust their size based on available disk space while capturing essential crash information. This option provides a balance between diagnostic value and storage requirements.

Enabling Memory Dump Creation

Before you can analyze dump files, ensure your system is configured to create them when crashes occur:

Press Windows + X and select System
Click on Advanced system settings in the right panel
Under the Advanced tab, click Settings in the Startup and Recovery section
In the System failure section, ensure Write an event to the system log is checked
Select your preferred dump file type from the dropdown menu
Verify the dump file path is set correctly
Click OK to save your settings

Note: Ensure you have sufficient free disk space on your system drive, as complete memory dumps can be several gigabytes in size.
