  • 32 bit can only see a max of 4GB - usually around 3.0 - 3.5GB, but if your hardware or graphics card is using shared memory it will be even less. Check to see how you can reduce your graphics card shared memory and increase available RAM, usually it's done in the BIOS, or in your GPU settings. Check your motherboard manual for other ways to increase available RAM.

    The usable memory may be less than the installed memory on Windows 7-based computers:

    To use over 4GB of RAM requires 64 bit Windows.
