beast_gts Posted June 17, 2009 Posted June 17, 2009 Hi Everybody Does anyone know what the maximum memory Server 2003 R2 (32-Bit) can 'see'? And what happens if you have more than that installed?
EduTech Posted June 17, 2009 Posted June 17, 2009 The maximum amount of memory that can be supported on Windows Server 2003 is 4 GB. However, Windows Server 2003, Enterprise Edition supports 32 GB of physical RAM and Windows Server 2003, Datacenter Edition supports 64 GB of physical RAM using the PAE feature. The virtual address space of processes and applications is still limited to 2 GB unless the /3GB switch is used in the Boot.ini file. When the physical RAM in the system exceeds 16 GB and the /3GB switch is used, the operating system will ignore the additional RAM until the /3GB switch is removed. This is because of the increased size of the kernel required to support more Page Table Entries. The assumption is made that the administrator would rather not lose the /3GB functionality silently and automatically; therefore, this requires the administrator to explicitly change this setting. The /3GB switch allocates 3 GB of virtual address space to an application that uses IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header. This switch allows applications to address 1 GB of additional virtual address space above 2 GB. The virtual address space of processes and applications is still limited to 2 GB, unless the /3GB switch is used in the Boot.ini file. The following example shows how to add the /3GB parameter in the Boot.ini file to enable application memory tuning: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(2)\WINNT [operating systems] multi(0)disk(0)rdisk(0)partition(2)\WINNT="????" /3GB 1
john Posted June 17, 2009 Posted June 17, 2009 Credit the source - IE Large memory support is available in Windows Server 2003 and in Windows 2000 that I posted last night
EduTech Posted June 17, 2009 Posted June 17, 2009 (edited) Credit the source - IE Large memory support is available in Windows Server 2003 and in Windows 2000 that I posted last night yeah meant to put that lol... so not with it tonight.. think i am just going to knock myself out and go sleep lol Easier to get it from a source, then to type it all out :-) James.

beast_gts Posted June 17, 2009 Author Posted June 17, 2009 Thanks, and I also found this one: Memory Limits for Windows Releases (Windows). The IT Manager has bought more memory than the server can handle... Should be fun
IanT Posted June 18, 2009 Posted June 18, 2009 Thanks, and I also found this one: Memory Limits for Windows Releases (Windows). The IT Manager has bought more memory than the server can handle... Should be fun Shouldn't he of researched before buying...........
beast_gts Posted June 18, 2009 Author Posted June 18, 2009 Shouldn't he of researched before buying........... He said he did research it, and Crucial said the server can take 32GB of RAM...
IanT Posted June 18, 2009 Posted June 18, 2009 He said he did research it, and Crucial said the server can take 32GB of RAM... Yeah the server may take 32Gb of RAM Physical but surely he must of known about the 32-bit Limitations
