    I have installed server 2003 R2 with SP2 on a HP Proliant ML 350 G6, the server has 12 GB RAM physical !The problem is that the OS do not see more than 4 GB RAM, I wonder how to fix so the R2 can se all 12 GB RAM. I have not installed anything else on the server, the only thing is the OS. Is any solution on this?

    Hi Emad,

    You installed 32bit OS or 64 bit ?

    32 bit processors cannot address more than 4GB of RAM, so to get round that you can use Physical Address Extensions (using the /PAE switch in the boot.ini) which enables you to utilise more than the standard 4GB.

    Enable PAE (Physical Address Extension) and check for the difference.

    Hi,

    This problem occurs because the address space is limited to 4 GB in a 32-bit hardware environment. Memory may be relocated to make room for addresses that the basic input/output system (BIOS) reserves for hardware. However, because of this limitation, Windows Server 2003 cannot access memory that is relocated above the 4 GB boundary.

    A 32-bit operating system can address memory that is relocated above the 4 GB boundary if the following conditions are true:

    •The computer is in Physical Address Extension (PAE) mode.

    •The computer has 4 GB of RAM.

    To enable PAE mode, you have to add PAE to the boot entry in the BCD file. Open an elevated command prompt. Type BCDEDIT /SET PAE ForceEnable.

    For more information, please refer to the following Microsoft KB article:

    Windows Vista, Windows Server 2003, or Windows Server 2008 may report less memory than you expect

    @above.

    Type BCDEDIT /SET PAE ForceEnable is not applicale on Window 2003 server.

    For Windows 2003 server, Put /PAE in boot.ini file.

    Thanks,

    Manoj
