How to Enable PAE

Save

PAE, or Physical Address Extension, is a process where, when enabled, a computer's x86 processor will be allowed to access up to 64 gigabytes of physical memory, while a x64 processor will be granted access for up to 1024 gigabytes of physical memory. This PAE is only available in 32-bit Windows systems and higher. This may be helpful when viewing content on the Internet, which may require more memory.

  • Open Microsoft Internet Explorer.

  • Click the "Tools" tab at the top of the screen. Select "Folder Options" from the pull-down menu.

  • Click on the "View" tab, select "Show Hidden File Folders," and clear "Hide protected operating system files." Select "OK," followed by "Yes."

  • Locate "Boot.ini" file in C: drive and remove the read-only attributes. Open the Boot.ini file and add "/PAE" to the end of the ARC path. The ARC path will have the Windows Server edition listed in its parameter title.

  • Click "File" and select "Save." Restore all the read-only attributes to the Boot.ini file. Now restart the computer. When the computer restarts the PAE will be enabled.
