Thanks !

 

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.

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.

Sounds like a good reason to check out 64-bit computing.

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.

 

Thanks

Re: 4GB of RAM tunning in windows xp professional xp sp2 with 32bi

 

Windows 2000 Advanced Server and Windows 2000 Datacenter Server support

the use of this switch and respectively support memory limits of 8GB and

32GB with the use of the switch. 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.

Is "large address aware" the same as PAE?

 

Does this mean that PS is capable of using PAE services?

PAE can be enabled in Win XP, (for Intel DEP), but it will not

enable XP to use more than 4GB. 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.

No.

Don't know what PS is, but 32-bit XP does not support PAE for address

space extension. 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. No exceptions.

XP supports PAE *only* to enable DEP (data execution prevention) NOT

to extend the address space.

Re: 4GB of RAM tunning in windows xp professional xp sp2 with 32bi

 

Can you please see this article from Microsfot. Go to this site

"http://www.microsoft.com/whdc/driver/kernel/mem-mgmt.mspx" and download the

meg-mgmt and check the specs on windows XP SP2 32bit.

 

They say Windows XP SP2 32 bits support 4GB of RAM and this is all what I'm

looking to. I only want to show 4GB of Memory.

 

Please advise

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.
