Chapter 1 Installing Windows

−

Specify a drive other than the system drive for "Dedicated Dump File".

Create the registry shown below by using the Registry Editor and specify the name of

Dedicated Dump File.

Note the following when specifying Dedicated Dump File:

• Pay strict attention to edit the registry.

• The setting is applied after restarting the system.

• Specify a drive that has free space of "installed memory size + 300 MB" or more.

• Dedicated Dump File cannot be placed in dynamic volumes.

• To collect memory dump by using Dedicated Dump File, a paging file is required in

any drive.

• Dedicated Dump File is only used for collecting memory dump, and is not used as

virtual memory. Specify the paging file size so that sufficient virtual memory can be

allocated in the entire system.

Key: HKEY_LOCAL_MACHINE\SYSTEM

\CurrentControlSet\Control\CrashControl

Name: DedicatedDumpFile

Type: REG_SZ

Data: D:\dedicateddumpfile.sys

Example of incorrect setting 1

C: Paging file whose size is smaller than the installed memory size

D: Paging file whose size is "installed memory size + 300 MB" or more

→

The paging file in drive C is used for collecting memory dump, but

collection may fail because the size of the paging file is smaller than the

installed memory size.

Example of incorrect setting 2

C: Paging file whose size is "installed memory size

0.5"

D: Paging file whose size is "installed memory size

0.5"

E: Paging file whose size is 300 MB

→ The total paging file size in all drives is "installed memory size + 300 MB",

but collection may fail because only the paging file in drive C is used for

collecting memory dump.

Example of incorrect setting 3

C: No paging file exists

D: Paging file whose size is "installed memory size + 300 MB" or more

(in dynamic volume)

→ Paging files in a dynamic volume cannot be used for collecting memory

dump. Thus, collecting memory dump fails.
