Recently tested a 32-bit program is always in 1.2G memory crashes, suspected memory request failed, itself 32-bit program can only apply to 2GB memory, after the various methods and tests found on the Internet, the following method is feasible, can apply to 4GB memory.

1. Run cmd in admin mode, enter: Bcdedit/set PAE forceenable Windows

The bcdedit here is about the command line's startup configuration Editor. With the above command, you can enable physical Address Extension (PAE) to allow more than 4GB of supported memory

2. Run cmd in admin mode, input: Bcdedit/set increaseuserva 3072

To allow Windows to allocate more than 2G of memory to the application!

3, restart the computer.

4. Recompile the program.

5, in the Beginning-"program-" visual studio2010-, Find "visual Studio Command Prompt (2010)" opens a CMD window set vs environment variable, executed at the command line:

Editbin/largeaddressaware your program name. exe

If you want to restore 2GB mode, use the following command to remove

1. Bcdedit/deletevalues PAE

2, Bcdedit/deletevalues Increaseuserva

3, restart the computer.

If you use VS2010 (other compilers are not tested), you can enable 4GB mode directly by selecting Yes in the project Properties-linker-system-enable large address.
