I know I don't have a choice, but what I was thinking the VMware for Sharepoint is Windows 2003 SP2. I thought may be I can allocate the Memory from the USB Flash Memory. The host is windows XP sp2 and the VMware 6.4 is windows 2003 SP2. What do you think John ? I don't want be Pain in .. but other wise I need to go and get new machines with Quad CPU.

Guest John John (MVP) Posted September 16, 2008 Posted September 16, 2008 Re: 4GB of RAM tunning in windows xp professional xp sp2 with 32bi Re: 4GB of RAM tunning in windows xp professional xp sp2 with 32bi That won't work! The host or underlying operating system (Windows XP) cannot fully access all the installed RAM so in turn the Virtual Machine and any software that it runs will not be able to access all the RAM. Even if you get a brand new machine with quad cores it still won't make any difference if the machine comes with a 32-bit XP/Vista workstation operating system. If VMware tells you to use the /3gb switch then use it, it will help by making more Virtual Address Space available to the application and in turn the Virtual Memory Manager will be able to map more of the VAS to physical memory addresses, but that will still not allow the use of the unavailable RAM, and it does not guarantee that the full 3GB of VAS will be mapped to the RAM, it will be mapped to available RAM and or the pagefile, it depends on what the kernel mode processes and non pagegable code needs for its use. Secondly, removable disks/flash memory cannot be used for the pagefile. And finally, Microsoft Office SharePoint Server requires Microsoft Windows Server 2003 Standard Edition, Windows Server 2003 Enterprise Edition, Windows Server 2003 Datacenter Edition or Windows Server 2003 Web Edition to run. Do you have one of these server versions? If not, how are you going to run this on VMware without one of these licenses? If you do own one of these Server licenses then, depending on the version that you own you may be able to install it on the computer and use PAE to fully access the RAM.

Guest Alvyn Posted September 16, 2008 Posted September 16, 2008 Re: 4GB of RAM tunning in windows xp professional xp sp2 with 32bi Re: 4GB of RAM tunning in windows xp professional xp sp2 with 32bi Dear John I saw that all is saying "NO" to support of memory more than 4GB in 32Bit OS. Can you please advice as I am confused on this when I read this statement found in : http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx "Physical Address Extension. PAE is an Intel-provided memory address extension that enables support of up to 64 GB of physical memory for applications running on most 32-bit (IA-32) Intel Pentium Pro and later platforms. Support for PAE is provided under Windows 2000 and 32-bit versions of Windows XP and Windows Server 2003. 64-bit versions of Windows do not support PAE." Correct me if I am wrong. I read the above statement as -> PAE can be supported in Windows 2000 & 32bit of WinXP & Win2003 Server. So long as PAE is enable in these OS, it can support up to 64GB of Physical Memory for applications running on 32bit Intel Pentium Pro & later platform. So can I presume that if I installed 8GB of memory with a Quad Core processor, I can fully make use of the rest of the available memory in running application like Photoshop & 3DS MAX up to a maximum of 64GB if I have /PAE switch in boot.ini? If I am wrong, can you please rephrase it so that I can have a better understanding on what this statement is talking about.

Windows 2000 Professional does not support the use of the switch. Windows XP supports PAE for hardware enforced Data Execution Prevention (DEP), even with the use of the switch the maximum available RAM that Windows XP supports is 4GB and because of the hardware limitations discussed in earlier posts Windows XP cannot address all the available RAM so it effectively cannot fully use 4GB of RAM. Current crop of Microsoft 32-bit operating systems that can utilise more than 4GB of RAM with the use of Physical Address Extension: Windows 2000 Advanced Server - 8 processors and 8 GB RAM Windows 2000 Datacenter Server - 32 processors and 32 GB RAM (support for 64 GB was not offered because of a lack of systems for testing) Windows Server 2003, Enterprise Edition - 8 processors and 32 GB RAM Windows Server 2003 SP1, Enterprise Edition - 8 processors and 64 GB RAM Windows Server 2003, Datacenter Edition 32 processors and 64 GB RAM Windows Server 2003 SP1, Datacenter Edition 32 processors and 128 GB RAM Operating Systems and PAE Support http://www.microsoft.com/whdc/system/platform/server/PAE/pae_os.mspx Physical Address Extension - PAE Memory and Windows http://www.microsoft.com/whdc/system/platform/server/PAE/PAEdrv.mspx For Windows workstations the only way around the issue is to use 64-bit hardware and a 64-bit workstation version.

PAE works in server editions of Windows on later editions of Intel CPUs by enabling 4 extra address lines to allow page switching of 16x4GB pages for a maximum of 64GB.

Period. 32-bit XP has a 4GB address space, some of that must be used for BIOS, video memory, etc. You *cannot* use 4GB of system RAM in 32-bit XP (or Vista). Period.

I only want to show 4GB of Memory. All 32-bit client versions of Windows (not just Vista/XP) have a 4GB address space. That's the theoretical upper limit beyond which you can not go. But you can't use the entire 4GB of address space. Even though you have a 4GB address space, you can only use *around* 3.1GB of RAM. That's because some of that space is used by hardware and is not available to the operating system and applications. The amount you can use varies, depending on what hardware you have installed, but can range from as little as 2GB to as much as 3.5GB. It's usually around 3.1GB. Note that the hardware is using the address *space*, not the actual RAM itself. The rest of the RAM goes unused because there is no address space to map it too. -- Ken Blake, Microsoft MVP - Windows Desktop Experience Please Reply to the Newsgroup
