i installed 16 GB RAM on the Intel SR1530HCLR but the properties in the window 2003 server sp2 32 bits show only 4 GB....anyone plz help me.....

Look in MSCONFIG (start, run it), the BOOT.INI tab => Advanced Options and see what MAXMEM is.

I had Edited Boot.ini and added a command /fastdetect /PAE in Boot.ini but still it is not recognizing the RAM. plz help me...

Physical Address Extension

Physical Address Extension (PAE) is a processor feature that enables x86 processors to access more than 4 GB of physical memory. 32-bit versions of Windows Server running on x86-based systems can use PAE to access up to 64 GB or 128 GB of physical memory, depending on the physical address size of the processor and the operating system version. For details, see Memory Limits for Windows Releases.

The Intel Itanium and x64 processor architectures can access more than 4 GB of physical memory natively and therefore do not provide the equivalent of PAE. PAE is used only by 32-bit versions of Windows running on x86-based systems.

With PAE, the operating system moves from two-level linear address translation to three-level address translation. 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). The size of page table entries (PTEs) and page directory entries (PDEs) in PAE mode is increased from 32 to 64 bits. The additional bits allow an operating system PTE or PDE to reference physical memory above 4 GB.

In 32-bit Windows running on x64-based systems, PAE also enables several advanced system and processor features, including 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 does not change the amount of virtual address space available to a process. Each process running in 32-bit Windows is still limited to a 4 GB virtual address space.

System Support for PAE

PAE is supported only on the following 32-bit versions of Windows running on x86-based systems:

Windows 7 (32 bit only)
Windows Server 2008 (32-bit only)
Windows Vista (32-bit only)
Windows Server 2003 (32-bit only)
Windows XP (32-bit only)
Windows 2000 Datacenter Server
Windows 2000 Advanced Server
Enabling PAE
Windows automatically enables PAE 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. If the computer does not support hardware-enabled DEP or is not configured for hot-add memory devices in memory ranges beyond 4 GB, PAE must be explicitly enabled.

To explicitly enable PAE, use the following BCDEdit /set command to set the pae boot entry option:


bcdedit /set [{ID}] pae ForceEnable
IF DEP is enabled, PAE cannot be disabled. Use the following BCDEdit /set commands to disable both DEP and PAE:


bcdedit /set [{ID}] nx AlwaysOff
bcdedit /set [{ID}] pae ForceDisable
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. To disable DEP, use the /EXECUTE switch.

Install server 2003 x64

32bit windows OSes are limited to 4gb, and only Server ENT x32 editions can use PAE. STD edition will not accept PAE.
