64 位^(64-bit)版本的Windows和Windows Server支持的物理内存 ( RAM ) 比 32 位版本支持的多。但是，配置或 增加页面文件大小^{(increase page file size)}的原因并没有改变。它一直是关于支持系统故障转储（如果有必要）或扩展系统提交限制（如果需要）。

例如，当安装了大量物理内存时，可能不需要页面文件来支持高峰使用期间的系统提交费用。仅可用的物理内存可能就足以做到这一点。但是，可能仍需要页面文件或专用转储文件来备份系统故障转储。

Windows 11/10 64 位版本的最佳页面文件大小^(File)

这就提出了应该分配多少pagefile.sys大小的问题？^{(pagefile.sys)}对于普通用户，最好将页面文件^{(Page File)}大小保留为其默认值，由Windows 操作系统^{(Windows OS)}决定。

大多数Windows PC 已经开始转向SSD^(SSDs)和NVMe，而且它们的成本很高。因此，让我们看一下可以帮助您确定合适尺寸的因素：

1. 故障转储设置
2. 峰值系统提交费用
3. 不常访问页面的数量

Windows将页面文件^(File)管理设置为自动^(Automatic)。它位于并且是一个隐藏文件。如果要手动配置，则可以使用此计算。此外，要完成此操作，您应该清楚地了解Pagefile以及它如何与管理员帐户权限一起使用。C:\pagefile.sys 

1]故障转储设置

以下^(Below)是Microsoft建议使用以下计算的计算：

* 1 MB 的标头数据和设备驱动程序可以总计 256 MB 的辅助故障转储数据。

Windows 将所有转储文件保存在%SystemRoot%Minidump并自动管理它们。如果要启用专用，DedicatedDumpFile则需要更改注册表^(Registry)项。

• 打开注册表编辑器^{(Registry Editor)}并浏览到以下项：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl

• 右键单击^{(Right-click)}CrashControl并^{(CrashControl)}创建一个新的字符串值^{(String Value )}并将其命名为DedicatedDumpFile
• 双击^(Double)它，并将值设置为  <Drive>:\<Dedicateddumpfile.sys>. 其中Drive是“D，E”等分区。
• 接下来，创建一个 DWORD DumpFileSize 并设置以兆字节 (MB) 为单位定义大小的值。

您还可以设置大小和其他因素。您可以在官方页面上^{(on the official page)}阅读更多相关信息。

2] 峰值系统提交费用

提交^(Commit)费用描述了保证所有进程适合物理内存和页面文件的虚拟内存总量。当您说峰值时，它是自操作系统上次启动以来总提交费用达到的最高金额。

3]不经常访问的页面数量+^(Quantity)

按照此方法找出不经常访问的页面数量+最小和最大页面文件大小。

我希望您能够为 64 位版本的Windows 11/10确定合适的页面文件大小。

What is the best Page File size for 64-bit versions of Windows 11/10?

64-bit versions of Windows and Windows Server support more physical memory (RAM) than 32-bit versions support. However, the reason to configure or increase page file size has not changed. It has always been about supporting a system crash dump, if it is necessary, or extending the system commit limit if it is needed.

For example, when a lot of physical memory is installed, a page file might not be required to back the system commit charge during peak usage. The available physical memory alone might be large enough to do this. However, a page file or a dedicated dump file might still be required to back a system crash dump.

That brings up the question of how much pagefile.sys size should be allocated? For regular users, it is best to leave the Page File size to its default value, by letting the Windows OS decide.

Most of the Windows PCs have started moving towards SSDs and NVMe, and they are costly. So let’s take a look at the factors which can help you determine the appropriate size:

1. Crash dump setting
2. Peak system commit charge
3. Quantity of infrequently accessed pages

Page File management is set to Automatic by Windows. It is located at C:\pagefile.sys and is a hidden file. If you want to configure it manually, then you can use this calculation. Also, to get this done, you should have a clear understanding of Pagefile and how it works with admin account privilege.

1] Crash dump setting

Below is the calculation Microsoft recommends to use the following calculations:

* 1 MB of header data and device drivers can total 256 MB of secondary crash dump data.

Windows keeps all dump files at %SystemRoot%\Minidump and manages them automatically. If you want to enable the dedicated, DedicatedDumpFile then you need to change a Registry entry.

• Open the Registry Editor and browse to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl

• Right-click on the CrashControl and create a new String Value and name it DedicatedDumpFile
• Double click on it, and set the value to  <Drive>:\<Dedicateddumpfile.sys>. Where Drive is the partition like “D, E” and so on.
• Next, create a DWORD DumpFileSize and set the value which defines the size in megabytes (MB).

You can also set size and other factors. You can read more about it on the official page.

2] Peak system commit charge

Commit charge describes the total amount of virtual memory guaranteed for all processes to fit in physical memory and the page file. When you say Peak, it is the highest amount that the total commit charge has reached since the operating system was last started.

3] Quantity of infrequently accessed pages+

Follow this method to find out the quantity of infrequently accessed pages+ for minimum and maximum page file size.

I hope you were able to determine the appropriate page file size for 64-bit versions of Windows 11/10.
