  • Hi farhad2161,

     

    This issue occurs because the available system RAM on a 32-bit computer is reduced to allow space within the first 4 GB of address space for PCI hardware configuration requirements. This behavior is expected on 32-bit computers that have 4 GB of RAM installed.

  • Hi farhad2161,

    To get 3.87GB out of 4GB is probably the best that you can get per Linda Yan's post on a 32-bit system. You may have hurt overall performance with the "patch"

    Right-click the desktop and install the CPU meter gadget and observe the memory usage in realtime. You won't even get close to ever using the entire 4GB unless you are editing videos or a cad item.

    Don't get concerned about the issue unless you begin to experience performance issues.

    Allowing Windows 7 to use the ram for system resources definitely helps overall performance.

    A faster processor or one with more L2 cache and a faster hard drive (7200rpm vs. 5400rpm) will increase the performance more than memory.
