Memory and Address Space Limits

The following table specifies the limits on memory and address space for supported releases of Windows.

Memory type	Limit in 32-bit Windows	Limit in 64-bit Windows
User-mode virtual address space for each 32-bit process	2 GB Up to 3 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE and 4GT	2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared (default) 4 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE set
User-mode virtual address space for each 64-bit process	Not applicable	With IMAGE_FILE_LARGE_ADDRESS_AWARE set (default): x64: 8 TB Intel IPF: 7 TB 2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared
Kernel-mode virtual address space	2 GB From 1 GB to a maximum of 2 GB with 4GT	8 TB
Paged pool	Limited by available kernel-mode virtual address space or the PagedPoolLimit registry key value. Windows Vista: Limited only by kernel mode virtual address space. Starting with Windows Vista with Service Pack 1 (SP1), the paged pool can also be limited by the PagedPoolLimit registry key value. Windows Home Server and Windows Server 2003: 530 MB Windows XP: 490 MB Windows 2000: 350 MB	128 GB Windows Server 2003 and Windows XP: Up to 128 GB depending on configuration and RAM. Windows 2000: Not applicable
Nonpaged pool	Limited by available kernel-mode virtual address space, the NonPagedPoolLimit registry key value, or physical memory. Windows Vista: Limited only by kernel mode virtual address space and physical memory. Starting with Windows Vista with SP1, the nonpaged pool can also be limited by the NonPagedPoolLimit registry key value. Windows Home Server, Windows Server 2003, and Windows XP/2000: 256 MB, or 128 MB with 4GT.	75% of RAM up to a maximum of 128 GB Windows Vista: 40% of RAM up to a maximum of 128 GB. Windows Server 2003 and Windows XP: Up to 128 GB depending on configuration and RAM. Windows 2000: Not applicable
System cache virtual address space (physical size limited only by physical memory)	Limited by available kernel-mode virtual address space or the SystemCacheLimit registry key value. Windows Vista: Limited only by kernel mode virtual address space. Starting with Windows Vista with SP1, system cache virtual address space can also be limited by the SystemCacheLimit registry key value. Windows Home Server, Windows Server 2003, and Windows XP/2000: 860 MB with LargeSystemCache registry key set and without 4GT; up to 448 MB with 4GT.	Always 1 TB regardless of physical RAM Windows Server 2003 and Windows XP: Up to 1 TB depending on configuration and RAM. Windows 2000: Not applicable

Dynamic Allocation of Kernel Virtual Address Space

In Windows Vista and later Windows releases, kernel VA space is dynamically allocated. The sizes and locations of important system resources—including the paged and nonpaged memory pools—are no longer fixed, but instead are dynamically adjusted according to operational requirements. As a result, system tuning is automatic. Administrators are not typically required to manually reconfigure systems to prevent resource imbalances.
