os 64 bit doesnt use all 4 gb

Hello,
I have win 7 enterprise 64 bit with 4 gb ram.
in device manager, i see that 4 gb is recognized, but actually only 3 gb has been used (it's written in bracket near to the recognized memory)

any idea why is that ?

thanks

You need to enable Memory remap in your BIOS if it is available

Big help would be to know the make and model of the motherboard.

If the chipset on the motherboard only supports up to 4 GB of ram then what you see is what you get, and short of a new motherboard there is nothing you can do,

The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

Quote:
When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating system is always less than the physical RAM that is installed. For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install 8 GB of RAM, the system memory that is available to the operating system will be reduced by the PCI configuration requirements. In this scenario, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately 200 MB and approximately 1 GB. The reduction depends on the configuration.
