 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.
<For example: "dedicateddumpfile.sys" in drive D>
Note the following when specifying Dedicated Dump File:
 The setting is applied after restarting the system.
 Specify a drive that has free space of "installed memory size + 400 MB"
("installed memory size + 1,800 MB" when the installed memory size is 4TB or
more) or more.
 Dedicated Dump File cannot be placed in dynamic volumes.
 Dedicated Dump File is only used for collecting memory dump, and is not used
as memory. Specify the paging file size so that sufficient virtual memory can be
allocated in the entire system.
System partition size
― ―
The system partition size can be calculated by using the following formula.
Size required to install the OS + paging file size + dump file size + application size
Desktop Experience
Size required to install the OS = 15,900 MB
Paging file size (recommended) = installed memory size + 400MB
Dump file size = installed memory size + 400MB
(installed memory size is 4 TB or less)
= installed memory size + 1,800MB
(installed memory size is exceeding 4 TB)
Application size = as required by the application
Server Core
Size required to install the OS = 10,700MB
Paging file size (recommended) = installed memory size + 400MB
Dump file size = installed memory size + 400MB
(installed memory size is 4 TB or less)
= installed memory size + 1,800MB
(installed memory size is exceeding 4 TB)
Application size = as required by the application
For example, if the installed memory size is 8 GB (8,192 MB), and application size is 100 MB,
the partition size is calculated as follows:
15,900MB + (8,192MB + 400MB) + 8,192MB + 400MB + 100MB
= 33,184MB
