A. To change the number of Page Table Entries (or System Pages) which are used for mapping I/O buffers and other information into the system address space perform the following:

  1. Start the registry editor (regedit.exe)
  2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
  3. Double-click SystemPages value and chose Decimal. Enter the amount of PTEs you need in the Data text box. Click OK. The maximum value is 50,000.
  4. Reboot the computer for the change to take effect.

By default the value is 0 which means use the system default.
