Page file sizing depends on the system crash dump setting requirements and the peak usage or expected peak usage of the system commit charge.

Both considerations are unique to each system, even for systems that are identical. This means that page file sizing is also unique to each system and cannot be generalized.

Use the following considerations for page file sizing for all versions of Windows and Windows Server. If you want a crash dump file to be created during a system crash, a page file or a dedicated dump file must exist and be large enough to back up the system crash dump setting.

Otherwise, a system memory dump file is not created.

For more information, see Support for system crash dumps section. The system commit charge cannot exceed the system commit limit.

This limit is the sum of physical memory RAM and all page files combined. If no page files exist, the system commit limit is slightly less than the physical memory that is installed.

Peak system-committed memory usage can vary greatly between systems. Therefore, physical memory and page file sizing also vary.

The purpose of a page file is to back support infrequently accessed modified pages so that they can be removed from physical memory. This provides more available space for more frequently accessed pages.

However, be aware that not all the memory on the modified page list is written out to disk. Typically, several hundred megabytes of memory remains resident on the modified list.

Therefore, consider extending or adding a page file if all the following conditions are true:. The dump file that is produced from this event is called a system crash dump.

A page file or dedicated dump file is used to write a crash dump file Memory. Therefore, a page file or a dedicated dump file must be large enough to support the kind of crash dump selected.

Otherwise, the system cannot create the crash dump file. During startup, system-managed page files are sized respective to the system crash dump settings.

This assumes that enough free disk space exists. The Automatic memory dump setting is enabled by default. This is a setting instead of a kind of crash dump.

This setting automatically selects the best page file size, depending on the frequency of system crashes. The Automatic memory dump feature initially selects a small paging file size.

It would accommodate the kernel memory most of the time. If the system crashes again within four weeks, the Automatic memory dump feature sets the page file size as either the RAM size or 32 GB, whichever is smaller.

Kernel memory crash dumps require enough page file space or dedicated dump file space to accommodate the kernel mode side of virtual memory usage.

If the system crashes again within four weeks of the previous crash, a Complete memory dump is selected at restart.

This requires a page file or dedicated dump file of at least the size of physical memory RAM plus 1 MB for header information plus MB for potential driver data to support all the potential data that is dumped from memory.

Again, the system-managed page file will be increased to back this kind of crash dump. If the system is configured to have a page file or a dedicated dump file of a specific size, make sure that the size is sufficient to back the crash dump setting that is listed in the table earlier in this section together with and the peak system commit charge.

Computers that are running Microsoft Windows or Microsoft Windows Server usually must have a page file to support a system crash dump. System administrators now have the option to create a dedicated dump file instead.

A dedicated dump file is a page file that is not used for paging. Dedicated dump files can be put on any disk volume that can support a page file.

We recommend that you use a dedicated dump file if you want a system crash dump but you do not want a page file.

07.02.2020 – The device comes with the newly announced Windows 10 S operating system, which enables faster boot times at the expense of the ability to download and install programs from the web instead of the Microsoft Store. Retrieved September 19, Surface Pen Write and draw naturally, with precision ink on one end and a rubber eraser on the other. The Surface’s built-in applications support screen rotation in all four directions, including upside-down.

By default, page files are system-managed. This means that the page files increase and decrease based on many factors, such as the amount of physical memory installed, the process of accommodating the system commit charge, and the process of accommodating a system crash dump.

For example, when the system commit charge is more than 90 percent of the system commit limit, the page file is increased to back it. This continues to occur until the page file reaches three times the size of physical memory or 4 GB, whichever is larger.

This all assumes that the logical disk that is hosting the page file is large enough to accommodate the growth.

The following table lists the minimum and maximum page file sizes of system-managed page files in Windows Several performance counters are related to page files.

This section describes the counters and what they measure. The following performance counters measure hard page faults which include, but are not limited to, page file reads :.

Hard page faults are faults that must be resolved by retrieving the data from disk. Such data can include portions of DLLs. These faults might or might not be related to a page file or to a low-memory condition.

Hard page faults are a standard function of the operating system. They occur when the following items are read:.

NET Framework applications execute. Asus Zenfone 3 ZE552KL Dual SIM 5.5″ Smart Phone with 4GB RAM, 64GB ROM — Pink Surface devices have a different amount of non-replaceable RAM , ranging from 2 to 32 GB, attached to the motherboard.

High values for these counters excessive paging indicate disk access of generally 4 KB per page fault on x86 and x64 versions of Windows and Windows Server.

This disk access might or might not be related to page file activity but may contribute to poor disk performance that can cause system-wide delays if the related disks are overwhelmed.

Therefore, we recommend that you monitor the disk performance of the logical disks that host a page file in correlation with these counters.

Be aware that a system that has a sustained hard page faults per second experiences KB per second disk transfers. No performance counter directly measures which logical disk the hard page faults are resolved for.

Not all the memory on the modified page list is written out to disk.

If a system is configured to have more than one page files, the page file that responds first is the one that is used. This means that page files that are on faster disks are used more frequently.

Be aware that actual page file usage depends greatly on the amount of modified memory that the system is managing.

This means that files that already exist on disk such as. Only modified data that does not already exist on disk for example, unsaved text in Notepad is memory that could potentially be backed by a page file.
