The following section describes one registry entry associated with 4-gigabyte tuning (4GT).

Note

  • 4GT is not required on the 64-bit versions of the Windows Server 2003 family.

4GT Registry Entry

The following registry entry is associated with 4GT.

The information here is provided as a reference for use in troubleshooting or verifying that the required settings are applied. It is recommended that you do not directly edit the registry unless there is no other alternative. Modifications to the registry are not validated by the registry editor or by Windows before they are applied, and as a result, incorrect values can be stored. This can result in unrecoverable errors in the system. When possible, use Group Policy or other Windows tools, such as Microsoft Management Console (MMC), to accomplish tasks rather than editing the registry directly. If you must edit the registry, use extreme caution.

PagedPoolSize

Registry path

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\

Version

Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition

This registry key determines the number of bytes allocated to the paged pool. It can be reduced in order to provide additional space for Paged Table Entries (PTEs). Because some computers require a certain amount of paged pool area size, reducing this value will not be an option in all cases. You should not typically need to change this registry value. The operating system calculates an optimal value for this entry based on the amount of physical memory on the computer.

Note

  • Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.
