From: John John (MVP) on 8 May 2008 09:33 From a Microsoft article: 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: • Intel 975X • Intel P965 • Intel 955X on Socket 775 • Chipsets that support AMD processors that use socket F, socket 940, socket 939, or socket AM2. These chipsets include any AMD socket and CPU combination in which the memory controller resides in the CPU. • The CPU must support the x64 instruction set. The AMD64 CPU and the Intel EM64T CPU support this 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. • An x64 (64-bit) version of Windows Vista must be used. Contact the computer vendor to determine whether your computer meets these requirements. Although this was written for Vista 64-bit I believe that applies to XP 64-bit. Ask on the 64-bit newsgroup for more help and advice.
