Graphics memory mapping overwrites a part of the system memory. These conditions reduce the total amount of system memory that is available to the operating system. The reduction in available system memory depends on the devices that are installed in the computer.
However, to avoid potential driver compatibility issues, the bit versions of Windows Vista limit the total available memory to 3. See the "More information" section for information about potential driver compatibility issues.
If a computer has many installed devices, the available memory may be reduced to 3 GB or less. However, the maximum memory available in bit versions of Windows Vista is typically 3. For Windows Vista to use all 4 GB of memory on a computer that has 4 GB of memory installed, the computer must meet the following requirements:. The chipset must support at least 8 GB of address space.
Chipsets that have this capability include the following:. The CPU must support the x64 instruction set. The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect PCI configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer.
View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature.
Contact the computer vendor to determine whether your computer meets these requirements. Note 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.
