აი, ახლახანს რას გადავაწყდი:

Physical Address Extension


The Physical Address Extension (PAE) allows 32-bit Windows systems to use more than 4 GB of physical memory. PAE also enables several advanced system and processor features so it can also be used on computers that have less than 4 GB of memory. Features enabled by PAE include hardware-enabled Data Execution Prevention (DEP), non-uniform memory access (NUMA), and the ability to add memory to a system while it is running (hot-add memory).

PAE is supported only on 32-bit versions of Windows; 64-bit versions of Windows do not support PAE. The following 32-bit Windows releases support PAE:

Windows Server 2008
Windows Vista
Windows Server 2003
Windows XP
Windows 2000 Datacenter Server
Windows 2000 Advanced Server

On most computers, PAE is disabled by default. (PAE is enabled by default only if DEP is enabled on a computer that supports hardware-enabled DEP, or if the computer is configured for hot-add memory devices in memory ranges beyond 4 GB.) PAE must be explicitly enabled for Windows to run in NUMA mode on a NUMA-capable computer.

To enable PAE, use the BCDEdit /set command to set the pae boot entry option.
Windows Server 2003 and Windows XP/2000: To enable PAE, use the /PAE switch in the Boot.ini file. To disable PAE, use the /NOPAE switch.

With PAE enabled, the operating system moves from two-level linear address translation to three-level address translation. The extra layer of translation provides access to physical memory beyond 4 GB. Instead of a linear address being split into three separate fields for indexing into memory tables, it is split into four separate fields: a 2-bit field, two 9-bit fields, and a 12-bit field that corresponds to the page size implemented by Intel Architecture (4 KB).

PAE, 4-gigabyte tuning (4GT), and Address Windowing Extensions (AWE) serve different purposes and can be used independently of each other:

PAE allows the operating system to access and use more than 4 GB of physical memory.
4GT extends the 32-bit user virtual address space from 2 GB to up to 3 GB.
AWE is a set of APIs that allows a process to allocate nonpaged physical memory and then dynamically map portions of this memory into the virtual address space of the process.

When neither 4GT nor AWE are being used, the amount of physical memory that a single 32-bit process can use is limited by the size of its address space (2 GB). In this case, a PAE-enabled system can still make use of more than 4 GB of RAM to run multiple processes at the same time or to cache file data in memory.

4GT can be used with or without PAE. However, some versions of Windows limit the maximum amount of physical memory that can be supported when 4GT is used. On such systems, booting with 4GT enabled causes the operating system to ignore any memory in excess of the limit. For details, see Memory Limits for Windows Releases.

AWE does not require PAE or 4GT but is often used together with PAE to allocate more than 4 GB of physical memory from a single 32-bit process.

ე.ი შეიძლება თითქმის ყველა 32 ბიტიან ვინდს 4გბ ზე მეტი დავანახოთ (IMG:style_emoticons/default/smile.gif)
სადღაც კი დავწერე ამ ფორუმზე ამის შესახებ, რადგან მანამდე ვიცოდი, რომ ეს მხოლოდ server2003 შეეძლო
ახლა კიდევ მაინტერესებს მისი წარმადობა, msdn-ზე არაფერია ნათქვამი
