Locating System Memory Error Dump Files
When a system error occurs in Windows operating system, the system automatically creates a memory dump file that contains information about the error and the state of the system at the time of the occurrence. This dump file can be extremely crucial to diagnose and identify the cause of system errors, crashes, and blue screens. However, the system memory error dump files are not located in a single directory or location and need to be located manually.
- Event Viewer: One way to locate the memory dump files in Windows is through the Event Viewer. Event Viewer is a built-in tool in Windows that logs all errors, warnings, and information related to the system. To locate the dump files, open the Event Viewer, navigate to the Windows Logs section, and look for the System log. In the System log, locate the event that matches the time of the system error and check its details. The details should include the location of the memory dump file.
- File Explorer: Another way to locate the memory dump files is through File Explorer. The dump files are usually saved with the extension .dmp and can be searched in the system drive (usually C: drive) using the search bar in File Explorer. Search for *.dmp and sort the results by date to locate the dump file that matches the time of the system error.
- System Properties: Windows allows users to configure the location and type of memory dump files generated by the system. To locate the dump file in this case, go to the Control Panel, navigate to System and Security, and select System. In the System window, select Advanced System Settings and navigate to the Advanced tab. In the Advanced tab, click on the Settings button in the Startup and Recovery section. This will open the System Properties window. In the System Properties window, click on the Advanced tab and navigate to the Startup and Recovery section. Here, you can find the settings related to memory dump files including their location.
Locating system memory error dump files is essential in diagnosing and identifying the cause of system errors. By using one of the above methods, users can easily locate the dump files and analyze them to determine the root cause of the system error.
Understanding the Purpose of Memory Dump Files
Memory dump files, also known as crash dump files or system dump files, are created by operating systems (OS) to capture a snapshot of the system memory when a computer or program crashes or freezes unexpectedly. The memory dump file contains information about the state of the system at the time of the crash, including the contents of the memory, the stack trace, and the registers. Analyzing a memory dump file can provide useful insights into the cause of the crash and help software developers or system administrators identify and fix the underlying problem.
Benefits of Memory Dump Files
- Diagnosing the cause of a system crash: Memory dump files provide a detailed snapshot of the system memory at the time of the crash, allowing developers or system administrators to diagnose the underlying cause of the crash.
- Debugging software errors: Memory dump files can be used to debug software errors such as memory leaks, buffer overflows, and race conditions by analyzing the contents of the memory and the stack trace.
- Reducing downtime: By analyzing memory dump files, developers or system administrators can identify and fix the underlying problem, reducing the downtime caused by crashes or freezes.
Types of Memory Dump Files
There are three types of memory dump files:
- Complete memory dump: This contains a copy of all the contents of the system memory and is typically very large, ranging from hundreds of megabytes to several gigabytes in size. A complete memory dump is useful for diagnosing hardware faults and low-level system issues but can be time-consuming to generate.
- Kernel memory dump: This contains a copy of only the kernel memory, which is the core of the operating system. A kernel dump is usually smaller than a complete memory dump but still contains enough information to diagnose most system crashes.
- Small memory dump: Also known as a mini dump, this contains only the essential information required to diagnose the cause of the crash, such as the stack trace and the value of the program counter. A small memory dump is the smallest and quickest to generate, but may not contain enough information to diagnose every type of system crash.
Configuring Memory Dump Settings
By default, most operating systems are configured to generate a small memory dump when a system crash occurs. However, the type of memory dump and the location where the dump file is saved can be configured using the System Properties dialog box or the registry. In Windows, for example, the memory dump settings can be found under Control Panel > System > Advanced system settings > Startup and Recovery.
| Parameter | Description |
|---|---|
| Write debugging information | Specifies the type of memory dump to generate when a system crash occurs. |
| Dump file | Specifies the location where the memory dump file is saved. |
| Automatically restart | Specifies whether the system should automatically restart after a crash or display a blue screen with an error message. |
Configuring the memory dump settings can be useful when debugging software or diagnosing system crashes, but care should be taken not to generate too many memory dump files, as they can consume a lot of disk space.
Types of Memory Dump Files
Memory Dump Files are the digital snapshots of the system’s memory taken when a crash or system error occurs. These files help technicians and developers to troubleshoot the error and resolve the issue. There are primarily three types of memory dump files –
- Complete Memory Dump
- Kernel Memory Dump
- Small Memory Dump/Minidump
Complete Memory Dump
A Complete Memory Dump file captures all the contents of the physical memory installed on the system at the time of the system crash. As it records all the data, it is the largest of all memory dump files, with its size ranging up to the size of the RAM installed on the system at the time of the crash. The Complete Memory Dump file is useful in cases where the issue is related to a hardware malfunction.
The Complete Memory Dump file can be found in the system’s root directory as MEMORY.DMP or %SystemRoot%MEMORY.DMP.
Kernel Memory Dump
A Kernel Memory Dump file captures data related to the system’s kernel when a crash or system error occurs. As it does not record all the contents of the physical memory, its size is much smaller than the Complete Memory Dump. Generally, the Kernel Memory Dump file captures data related to the crash in addition to the Kernel-mode drivers loaded on the system.
The Kernel Memory Dump file can be found in the system’s root directory as MEMORY.DMP or %SystemRoot%MEMORY.DMP.
Small Memory Dump/Minidump
A Small Memory Dump or Minidump file captures a small amount of data related to the system errors. It only captures the critical information required to understand the error’s cause and is the smallest of all the memory dump files, making it easier to transfer for analysis. Typically, it captures the memory only for the crashed process and a small section of the kernel.
| Types of Small Memory Dumps | |
|---|---|
| Small Memory Dump: | It captures data related to the crashed process. |
| Small Kernel Memory Dump: | It captures data related to the Kernel memory dump along with the crashed process. |
| Automatic Memory Dump: | The Automatic Memory Dump is primarily used in Windows 8 and Windows 10 systems. The system is configured to capture the Small Memory Dump by default, but in case it cannot generate the Small Memory Dump, it automatically switches to the Kernel Memory Dump. |
The Small Memory Dump files are located in the %SystemRoot%Minidump folder.
Understanding the types of Memory Dump Files helps to streamline the troubleshooting process and resolve the issue. It is always advisable to send the relevant Memory Dump files to technical support for prompt resolution.
Analyzing Memory Dump Files
When a system error occurs, the operating system creates a memory dump file to save the state of the system at the time of the error.

- Kernel dump files contain more information about the system state and are useful for analyzing crashes that involve system-level components.
- Complete dump files contain the entire memory image of the system at the time of the crash. They are useful for analyzing complex crashes that involve multiple processes and drivers.
Using Debugging Tools
Debugging tools such as WinDbg and KD (Kernel Debugger) can help you analyze memory dump files and identify the root cause of the crash. These tools provide a command-line interface for inspecting memory, registers, threads, and modules, and can also load symbol files for improved debug output.
When using debugging tools, it is important to have a basic understanding of the operating system architecture, the relevant system components, and the debugging commands. You can find many online resources and tutorials that cover these topics.
Examining Error Codes and Call Stacks
Error codes and call stacks can provide valuable information about the nature and location of the crash. Error codes indicate the type of exception or error that occurred, while call stacks show the sequence of functions and modules that led to the crash.
You can use the WinDbg or KD command “kp” to display the current call stack, or “kb” to display the call stack for a specific thread. You can also use the “!analyze -v” command to automatically analyze the crash and generate a summary report.
Identifying Faulting Modules and Drivers
| Module Name | Module Address | Module Size | Timestamp |
|---|---|---|---|
| ntoskrnl.exe | fffff800`02000000 | 0x1d4000 | 0x55f9d76c |
| nvlddmkm.sys | fffff801`9f6d8000 | 0x2a8f000 | 0x5ae4a2fc |
| dxgkrnl.sys | fffff801`9f9a8000 | 0x1e9000 | 0x60cfb7a9 |
Faulting modules and drivers are often the primary cause of system crashes. You can use the WinDbg or KD command “lm” to list all loaded modules and drivers, and then look for any modules or drivers that have an address or timestamp that matches the crash report. You can also use the “!analyze -v” command to identify the faulting module or driver.
Once you have identified the faulting module or driver, you can try updating the driver or disabling the module to see if the problem goes away. Keep in mind that some modules and drivers are essential for the system to function properly, so you should only make changes if you are confident in their impact.
