    Summary Capture One 6: Out of memory on Windows 32bit OS (XP, Vista, 7)
    Problem The system reports out of memory and needs to be restarted
    Solution Due to the increased demand in system memory Capture One requires for advanced tasks and handling ever bigger files, the 32bit OS has certain limitations under its default configuration.

    Ultimately the best solution is to upgrade the OS to 64bit.

    A workaround for users who do not have this option is to enable the 3gb switch, therefore extending the virtual address space for process and applications.

    This is a system wide change so all applications that use IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header will be effected.

    Enable the 3GB switch on Windows XP

  • Right-click My Computer. Click Properties.
  • In the System Properties dialog box, click the Advanced tab.
  • On the Advanced tab, under Startup and Recovery, click Settings.
  • In the Startup and Recovery dialog box, under System startup, click Edit.



    The Windows boot.ini file will be opened in Microsoft® Notepad.

    Create a backup copy of the boot.ini file. Note: Boot.ini files may vary from computer to computer.
    Select the following line in the boot.ini file:

    multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional"/noexecute=optin /fastdetect

  • Press Ctrl+C to copy the line and then press Ctrl+V to paste it immediately below the original line.
  • Note: Your text string may be different from the text string in this solution, so be sure to copy the text string from your boot.ini file, and not the text string included here.
  • Modify the copied line to include “ /3GB”, as shown in the following example:

    multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional 3GB" /3GB /noexecute=optin /fastdetect



    Note: Do not overwrite any existing lines.

  • Save and close the boot.ini file.
  • Click OK to close each dialog box.
  • Restart your computer.
  • During startup, select the 3GB option. If you do not select the 3GB option, the system will default to the 2GB total memory setting.

    Note: If problems occur during startup, you may need to update some of your drivers.




    Enable the 3GB switch on Windows Vista/7

  • Right-click Command Prompt in the Accessories program group of the Start menu. Click Run as Administrator.
  • At the command prompt, enter "bcdedit /set IncreaseUserVa 3072"
  • Hit enter
  • Restart the computer.






    Disable the 3GB switch on Windows Vista

  • Right-click on Command Prompt in the Accessories program group of the Start menu. Click Run as Administrator.
  • At the command prompt, enter "bcdedit /deletevalue IncreaseUserVa"
  • Hit enter
  • Restart the computer.
