Memory Dump
If memory dump is set, debugging information will be automatically saved when a STOP error (fatal
system error) occurs in the system. Using the saved memory dump, error cause can be analyzed.
If the amount of installed memory is large, pay special attention when setting the memory dump file.
The settings for obtaining memory dump should be configured after installing the files to be used for
operations (OS, applications, etc.).

stored in the directory displayed in the [Dump file] box.
• Paging file: Installed physical 11MB (Recommended: Installed physical memory x 1.5)

For memory of 256 to 1,373MB - Installed physical memory x 1.5
For memory of 1,374MB or more - 32-bit system: 2GB + 16MB, 64-bit system: Installed physical
128MB
• Memory dump file: Depending on the used amount of kernel-mode address space during STOP
