Ok can I chuckle on this? Too bad I will anyway J I understand the
reasoning for checking it out, but how much time did you spend on this?
How much is 1GB of RAM? How much performance improvement will you see
with the 300MB gain on a 4GB system?

 

OK now that devil's advocate is done, I'm glad you did that Ed, that is
useful information and clears up a mystery. Nice work!

Folks, I stand semi=corrected J 

 

Looking at it again, Winver is telling me 4.0GB and msinfo32.exe is
showing me like 3.7-3.8GB right now. With the PAE switch in there. If I
take the PAE switch out winver shows 3.4, and Msinfo32.exe shows about
3GB available to windows. 

 

So /PAE isn't making it totally see 4GB but does make about a 300-400MB
improvement in the amount of memory seen in windows on a DL 380 G5
system. 

 

Its about the best that you can do I guess without going X64 or paying
more for Enterprise Edition and not using all the features.

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Ken Cornetet]

The fundamental issue at hand is not peculiar to Intel's X86, but rather
with all 32 bit CPUs in general. With only 32 bits of address space, you
have to do some sort of "magic" to address more than 4GB of physical
address space. Only very recently have computer designers had the luxury
of enough logical address bits (64) to not need some sort of virtual to
physical mapping scheme to extend the addressing space.

 

But I do agree that things are a whole lot simpler with the advent of 64
bit systems. No more worries about /3GB, /PAE, non-paged pool memory,
AWE and the like.  

 

Sigh, I guess I'm showing my age, but I can remember when 32 bits of
address space seemed to be equivalent to "infinite" and I was saying how
nice it was that we'd never have to worry about address space
limitations again.

But it is an issue of the X86 architecture :-)  It's showing it's age.
Intel has tricks to get around such limitations (like adding extra bits
to the addressing lines or relocating stuff) but these are fundamental

Low end servers also often have this limitation.  Being able to fully
address a full 4 gigs of RAM on a wide variety of motherboards is a
pretty recent innovation, at least for the Intel PC world. 

Anyway, I think we agree - it's the chipset, not the OS.

You are right about loading server 2003, but the problem is the chipset
on your laptop, not the X86 architecture. I'm guessing that most
workstation grade chip sets don't have the ability to relocate the
shadowed RAM to a physical address above 4GB. That's makes pretty good
sense considering that few workstations have 4GB of RAM.

So we are now stuck on the horns of an enema, um, I mean dilemma. We have
documentation that implies that the PAE switch should *never* give memory
back regardless of the chipset capabilities, and we have empirical evidence
from Edward Ziots that adding the PAE switch does indeed return some of the
missing memory. 

 

Z stated that Windows showed two different values depending on where he
looked. I wouldn't call that empirical evidence of returning anything. It
just caused some numbers to change in one location and not another. I don't
think this means anything.

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Ken Cornetet]

Right.

 

It's just like back in the 286 days. When you put in a whole megabyte of
RAM, you lost the upper 384KB due to video memory, EMS frames BIOS,
memory mapped network cards, etc. If you were lucky, your chipset could
relocate the lost 384KB of ram to physical addresses just above 1MB. In
real mode the CPU couldn't access the memory because real mode X86 is
limited to 20 bits of physical address.

 

However, add EMM386 to the config.sys and the CPU went into an extended
X86 mode which allowed those 20 bits of address space to be mapped to a
much larger physical address space. EMM386 could then map part of the
relocated 384KB of RAM back down into unused spots of the area between
640K and 1MB.

 

The same thing is happening here, except that the limitation is
artificial instead of physical.

 

My point of curiosity was to find out where exactly where server 2003
standard and XP are throttled. Was it at the physical address space
level, or the amount of usable RAM level? The document referenced by Ken
Schaefer clearly stated that server 2003 standard was limited to 4GB of
physical address space. This would mean that even if the chipset could
relocate the .5GB to an area above 4GB AND the PAE switch was used to
get 36 bit addresses, you still would not get the additional RAM back
because of the OS limit.

 

On the other hand, if the 4GB limit was a RAM limit and not a physical
address space limit AND your chipset could relocate the shadow memory
AND the PAE switch was used, you should get some of the memory back.

 

So we are now stuck on the horns of an enema, um, I mean dilemma. We
have documentation that implies that the PAE switch should *never* give
memory back regardless of the chipset capabilities, and we have
empirical evidence from Edward Ziots that adding the PAE switch does
indeed return some of the missing memory. 

 

I'm figuring that the documentation is wrong, or possibly was never
updated to match a change in the code at some point. I realize there are
other possible explanations for Ed's observations, but I'm going with
what I consider the simplest: the docs are wrong. Besides, from an OS
point of view, it makes more sense to me to simply limit the amount of
RAM that is usable than to limit the physical address space which might
make you incompatible with certain motherboards or PCI cards.

/PAE with XP on my laptop makes no difference - I see a little over 3.5
gig no matter what I do.  As others have posted, you get varying results
on different machines due to the chipset you have, how many PCI devices
you have and how your BIOS is configured.  This issue is why Apple
didn't ship early MacBooks with more then 3 gigs of RAM - the pre-945
Intel chipset simply couldn't offer the extra memory for use (see, even
Mac OS X can't change the characteristics of hardware). 

You are seeing artifacts of the Intel X86 architecture combined with
32bit operating systems - it's not pretty, nor consistent.  Newer
chipsets like the Intel 945 chipset family do not have these limitations
on some hardware - on a MacBook Pro, Mac OS X can see all 4 gigs of RAM.
On my Dell Latitude D630, I can only see a little over 3.5 gigs of RAM.
Dell is doing something different then Apple, and I would wager it's the
legacy PCI support that is consuming that half a gig or so of RAM.
Legacy PCI support is obviously not an issue for Apple. 

Did that help?

For a laptop, you need to check both chipset limitations, as well as your OS 
limitations. Check the Intel 945GM chip documentation that i posted in a 
previous post.

In section 9.2 you can see that the chipset also had an addressing limitation 
(regardless of what OS you are running), and that various devices use various 
addresses already.

All that has been proven is Windows can't consistently report one piece of 
information from one location to the other. I indicated earlier that Vista SP1 
will show memory installed and not useable memory as well... which will start 
this conversation all over again then. ;) I wonder what memtest would show? 
Also, I know we're speaking of Windows mostly here, but this isn't a only 
limitation so much of Windows or 32bit operating systems, but more a limitation 
of x86. As a side note, AMD doesn't support /PAE, and I haven't put any time in 
to finding out what AMD does in these cases.

TO all,  ( Ken I hate to say it, but I have seen this with me own eyes, and the 
/PAE switch does enable you to see the 4GB)

I have proven that the /PAE switch has worked on a DL 380 G5 system with 4096 
MB of RAM at post. Running Windows 2003 R2 SP1.

Before putting the /PAE switch in the boot.ini the memory available to Windows 
( via MSinfo32.exe and winver was 3.4GB)
After putting the /PAE switch in the boot.ini the memory availbile to Windows ( 
via Msinfo32.exe and Winver was 4GB)

The system I tested on was built with 4GB of RAM already in the system, and 
when it was finished being built showed 3.4GB of RAM available to windows. I

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS Followup.

[Michael B. Smith]

No boot.ini in Vista or Windows Server 2008, they use BCD.

 

Regardless, I set "bcdedit /set pae ForceEnable" and rebooted, and there is
no change in what is reported in task manager.

Try adding the /PAE switch in the boot.ini and see if you get any lost RAM
back.

Ok, I stand corrected. That document does clearly state that the physical
address space is limited to 4GB. Given that, I would indeed expect the /PAE
switch to not make the missing RAM show up.

 

The odd thing is that I know I have seen this in the past (DL380 3.5GB
showing), and I could have sworn that putting something in the boot.ini made
the missing half gig return. The more I think about it, though, I believe
the OS was w2k3 enterprise, since the server was destined to be a SQL server
box and was going to have more RAM added down the road. 

 

What is "FFS" you mentioned in your other post?

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS Followup.

[Ziots, Edward]

Folks, I stand semi=corrected :-) 

 

Looking at it again, Winver is telling me 4.0GB and msinfo32.exe is
showing me like 3.7-3.8GB right now. With the PAE switch in there. If I
take the PAE switch out winver shows 3.4, and Msinfo32.exe shows about
3GB available to windows. 

 

So /PAE isn't making it totally see 4GB but does make about a 300-400MB
improvement in the amount of memory seen in windows on a DL 380 G5
system. 

 

Its about the best that you can do I guess without going X64 or paying
more for Enterprise Edition and not using all the features.

Can someone with an affected system (4GB of physical RAM, 3.5GB showing, 2003 
std) add the /PAE switch and reboot to see if it makes the rest of the RAM 
visible? If memory serves, Microsoft limits the *amount* of RAM in standard to 
4GB, it does not limit the physical address to 0x and below. I think 
the /PAE switch will make the missing RAM show up, but I don't have a test 
server with 4GB of RAM and 2003 standard to test on at the time.

The memory management whitepaper that I've posted explains all of this:
http://www.microsoft.com/whdc/driver/kernel/mem-mgmt.mspx

Pages 9-12 will give you lots of information on physical addressing, bus 
addressing, how devices can use addresses and so on.

Mike,

I am seeing what you are saying.

BIOS in the server I am seeing 3.7GIG only has a NIC card in it, and Dual P4 
processors, a Smart Array 6i card.

BIOS I am seeing 3.4 GIG has T1 Inte Dialogic Card, Dual NIC's Smart Array 
controller, Dual P4 Processors.

So the more PCI Type devices it seems that are in the system the less physical 
memory you are going to have for Windows.

NO server has Audio here, no need for it. All servers have CD/DVD drives and 
SAS or SCsi HD's.

I have seen a system with 4GB of RAM show 3.4GB and a system with over 5GB of 
RAM show 3.7GB accordingly.

So it looks like ordering Enterprise Edition is in the works, since a lot of 
our application probably aren't going to be supported on X64 edition by the 
vendors accordingly.

/PAE won't do anything with a computer that has only 4GB of mem with an OS that

Thanks for the information, I have boxes that have DEP enabled, and don't have

to go hand in hand. I got 3 DL 380 G5 that will refute that.

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Mike Gill]

It can't. Win2K3 STD only supports 4GB of address space, which 4GB of memory
would need to occupy. System components such as video cards, the BIOS and
the like, need resources in this address space, and can only use address
space below the 4GB barrier. This means OS's that only support 4GB of
address space, and have 4GB of memory installed, will never be able to use
all of it, because some of that address space is already used. /PAE will
enable access to address space above the 4GB barrier. So memory that was
bumped below the 4GB address space can reside in this newly available
extended address space above the 4GB barrier and become available.  Since
this is address space beyond the 4GB barrier, 32bit OS's such as 2K, XP, and
2K3 STD will not be able utilize /PAE for its primary purpose in the context
of this discussion.

 

Address space and the memory that uses it need to be separated to understand
this properly.

Can someone with an affected system (4GB of physical RAM, 3.5GB showing,
2003 std) add the /PAE switch and reboot to see if it makes the rest of the
RAM visible? If memory serves, Microsoft limits the *amount* of RAM in
standard to 4GB, it does not limit the physical address to 0x and
below. I think the /PAE switch will make the missing RAM show up, but I
don't have a test server with 4GB of RAM and 2003 standard to test on at the
time.

Mike, 

 

I am seeing what you are saying. 

 

BIOS in the server I am seeing 3.7GIG only has a NIC card in it, and Dual P4
processors, a Smart Array 6i card. 

 

BIOS I am seeing 3.4 GIG has T1 Inte Dialogic Card, Dual NIC's Smart Array
controller, Dual P4 Processors. 

 

So the more PCI Type devices it seems that are in the system the less
physical memory you are going to have for Windows. 

 

NO server has Audio here, no need for it. All servers have CD/DVD drives and
SAS or SCsi HD's. 

 

I have seen a system with 4GB of RAM show 3.4GB and a system with over 5GB
of RAM show 3.7GB accordingly. 

 

So it looks like ordering Enterprise Edition is in the works, since a lot of
our application probably aren't going to be supported on X64 edition by the
vendors accordingly.

memory, but not use it.  PAE enables address space above 4GB. It's also
required for DEP, and must also be supported by your hardware (e.g.
chipset) and drivers. Why some people here are seeing all 4gb in the
properties dialogue of 2K3 std, I don't get it. I thought I understood
this issue, but obviously there are some real world experiences here
showing otherwise.

The memory management whitepaper that I've posted explains all of this:

Pages 9-12 will give you lots of information on physical addressing, bus 
addressing, how devices can use addresses and so on.

Mike,

I am seeing what you are saying.

BIOS in the server I am seeing 3.7GIG only has a NIC card in it, and Dual P4 
processors, a Smart Array 6i card.

BIOS I am seeing 3.4 GIG has T1 Inte Dialogic Card, Dual NIC’s Smart Array 
controller, Dual P4 Processors.

So the more PCI Type devices it seems that are in the system the less physical 
memory you are going to have for Windows.

NO server has Audio here, no need for it. All servers have CD/DVD drives and 
SAS or SCsi HD’s.

I have seen a system with 4GB of RAM show 3.4GB and a system with over 5GB of 
RAM show 3.7GB accordingly.

So it looks like ordering Enterprise Edition is in the works, since a lot of 
our application probably aren’t going to be supported on X64 edition by the 
vendors accordingly.

/PAE won’t do anything with a computer that has only 4GB of mem with an OS that 
only supports that much memory which include XP and 2K3 STD. It enables 
extended (Physical Address Extension) address space beyond 4GB. What you’re 
seeing right now is what you’re supposed to be seeing. These other people that 
are seeing 4GB reported as available in the Windows > Properties > General tab 
on STD edition is what is perplexing to me. I would like to think they’re just 
wrong on something but as I’m not there looking at what they’re looking at, 
well… Maybe they could call up their MS person and tell them what they’re 
seeing and ask why they’re seeing it.  Because every piece of documentation 
I’ve read says they shouldn’t be able to do that.

As for refuting the DEP thing, again, if these machines are running 2K3 STD and 
only have 4GB of mem installed then you shouldn’t evar™ see 4GB of physical mem 
in the task manager or properties dialogue.

Answer this. Your machine that shows 3.7GB.  Does it have less installed in 
terms of components?   Are more components disabled in the BIOS than other 
similar machines such as onboard audio, extra NIC’s, or possibly no CD or hard 
drives? I would make sense if this is true.

Thanks for the information, I have boxes that have DEP enabled, and don’t have 
the /PAE in the boot.ini therefore DEP automatically enabling PAE doesn’t seem 
to go hand in hand. I got 3 DL 380 G5 that will refute that.

Again going to try the /PAE switch on a system and see if anything changes 
accordingly, as compared to a freshly built system with 4GB in it.

I looked at a few other systems, and some of them have 5GB of memory but only

Re: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Phil Brutsche]

Absolutely correct; this is a hardware issue, and you will see this
happen on machines with 4GB RAM and Intel chipsets, regardless of OS or
OS configuration (I've seen it with XP, 2003 Standard and Linux).

I have some systems with 4GB RAM on SuperMicro PDSME+ motherboards and
PCI-E RAID cards, and this is what the MB manual has to say about it:

"Due to memory allocation to system devices, memory remaining available
 for operational use will be reduced when 4 GB of RAM is used. The
 reduction in memory availability is disproportional. (Refer to the
 Memory Availability Table below for details."

The list won't let me attach a screenshot, so the table is at the top of
page 27 in this PDF:

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[David Lum]

Thanks for the info Mike, that was a great post earlier!

 

Reminds me of the old DOS 640K "limit", then using EMM386 and LH
commands you can eke some more out of it, then use DOS extenders to
really get some RAM usability. I'm guessing what we're seeing with 4GB
installed but OS showing 3.5-ish GB  the same principle.

 

We have some IBM "dual chassis" servers where the additional CPU's and
RAM are on the additional chassis (or partition using IBM's
nomenclature). Just having the partition uses .5GB of available RAM.

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Glen Johnson]

I'll just throw this in as a point of reference.

On the system properties of both Dell servers where I see 4gig, the last
line of the display says Physical Address Extensions, although I also
see that on a same model server with 2gig ram.

I know it's not something I set up when installing the OS.  Could be in
the BIOS, don't know and can't check right now.

No /PAE in the boot.ini either.

I don't think I'd consider calling MS on this.  They might take away my
extra ram.

I'll be glad to provide any additional info from the systems in question
if anyone is interested.

PAE on an OS that is limited to 4GB, is only because DEP requires it.
Enabling DEP automatically enables PAE. Otherwise it (PAE) would be a
useless feature on 2K/XP/2K3 std. The BIOS, video cards, memory, et al, all
use address space. When you only have 2GB in the machine, there is a lot of
address space left over and unused by the memory you don't have installed.
When you put all 4GB in the machine however, then there isn't any address
space left available for your installed components (video cards, BIOS,
drives, et al.) which also use this address space, so something has to give.
This is why you see less than 4GB typically. But then there are these people
that are seeing the 4GB in Windows and it defy's what should really be
happening as I understand it.

 

Vista 32bit w/ SP1 will report installed memory and not useable memory. So
people will see their 4GB, but not actually be able to use it. Weird.

Thanks for the information, I have boxes that have DEP enabled, and
don't have the /PAE in the boot.ini therefore DEP automatically enabling
PAE doesn't seem to go hand in hand. I got 3 DL 380 G5 that will refute
that. 

 

Again going to try the /PAE switch on a system and see if anything
changes accordingly, as compared to a freshly built system with 4GB in
it. 

 

I looked at a few other systems, and some of them have 5GB of memory but
only Win2k3 STD shows 3.7GB on some and 3.4 on others. 

 

Its pretty weird,

Intel machines running 32bit versions of Windows can address 4GB of
memory, but not use it.  PAE enables address space above 4GB. It's also
required for DEP, and must also be supported by your hardware (e.g.
chipset) and drivers. Why some people here are seeing all 4gb in the

You don't mention whether you are running x64 or x86 edition of Server
2003.

 

Also, depending on the hardware you have the device you might only
"lose" accesss to a few MB of RAM (or maybe none at all). My HP ML330
only loses about 60MB, so instead of 4096 it reports 4036, which looks
very similar to 4GB of RAM.

 

But you can disagree all you like - you'd still be wrong :-)

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Glen Johnson]

Could be crazy  Nothing new for MS.  I'm just going by what others have
said here on the list.

IIRC, wasn't there something in an old version of windows that if you
had less than a certain amount of ram, you got one kernel driver or some
low level software, but if you had more than say 128k or meg you got a
different one.  This was during the hardware detection phase of the
install.  Later if you upgraded the ram, you wouldn't see optimum
performance unless you did a reinstall.  I know, I'm showing my age here
cause I think that was in Win95 or maybe 98.

Maybe something similar is going on here.  Mind you, I just guessing so
take it for what it's worth.

It just seems that people that had 4 gig in during the OS install can
use almost all of it but others that have upgraded to 4 gig are losing
access to as much as 500meg.

Thanks.  I had looked there and didn't see anything that said either way. So 
since it doesn't say x64, guess that means it is x32.
So I stand by my original statement, x32 standard windows 2003 R2 can see and 
use 4gig, give or take a few kb regardless of what blogs, white papers and such 
may say.
Looks like the main thing is that the system must be at 4gig during the OS 
install.

I'm 99.9% sure it is the x32 version.  The original media doesn't say one way 
or the other and  I'm not finding anything in any of the system properties that 
says either way.
Anyone know how to tell after install if it is x32 or x64?
Now conflicting info from MS is a new one for me.  NOT.
Anyway, from MSCONFIG, About windows says Physical Memory Available to 
Windows:  4,193,268 KB
Task manager shows the same number for Physical Memory Total
I just checked a second server that I know for certain has x32 and it shows 
4,193,360 KB
Looks like either the 4 gig has to be there when the OS is installed or could 
possibly be something different with Dell hardware, which both of these are.

No I did not.  And if that is the case, that you need the 4 GB at time of 
install, then as far as I am concerned it does not support 4 GB of RAM.  I 
talked to M$ directly and they said that in the x32 version of Win2K3, you will 
not get the full 4 GB of RAM, only on the x64 edition.  You may have the x64

Nothing is going to change. You are running Windows Server 2003 Standard 
Edition x86. This has a built-in limitation (in the code) which prevents 
Windows using addresses beyond 0xF

If you are using x86, put Enterprise Edition on there (with /PAE). Or put x64 
Standard Edition on there.

The limitation you are running into is hard coded into the OS.

Some says that it's because the BIOS reserves 512MB "physical" address space 
just below the 4GB line and put the real 512MB RAM above the line. Thus only 
the PAE kernel sees that 512MB RAM.
This isn't a correct explanation of what you are seeing.

The BIOS doesn't reserve "RAM". PCI (and PCI-X and PCIe) devices can reserve 
memory addresses. These overlap with addresses that the Windows OS uses. The 
BIOS has masked these addresses, making the unavailable to Windows to address 
the physical RAM.

The use of the /PAE switch enables three layers of page tables to be used. If 
you are familiar with B-trees in databases, you'll be familiar with the concept 
of tables of tables of pages of memory (3 layers). Without PAE you only get 
tables of pages (two layers). The extra layer of tables makes available a whole 
set of addresses that wouldn't otherwise be available. These addresses can be 
used to address the physical RAM that Windows can't otherwise get to.

re: Myth: PAE increases the virtual address space beyond 4GB
Wednesday, August 18, 2004 9:05 AM by timchen
There is one thing quite interesting about /PAE. On some machines with 4GB RAM 
installed, Task Manager shows only 3.5GB physical memory. However, if you 
switch to the PAE kernel, all 4GB is shown.

Some says that it's because the BIOS reserves 512MB "physical" address space 
just below the 4GB line and put the real 512MB RAM above the line. Thus only 
the PAE kernel sees that 512MB RAM.

I'm not sure if the explanation is true or not, but the symptom is confirmed.

There is no such limit using a 32bit Windows OS. What you observe is a

"loses" about 64MB of memory when using standard Windows Server 2003 x86

No I did not.  And if that is the case, that you need the 4 GB at time
of install, then as far as I am concerned it does not support 4 GB of
RAM.  I talked to M$ directly and they said that in the x32 version of
Win2K3, you will not get the full 4 GB of RAM, only on the x64 edition.
You may have the x64 edition.

I respectfully disagree here.

See my previous post.  Dell 2950 with Win2k3 R2 STD and it uses all
4gig.

As a point of reference, did you have 4 gig in when the OS was
installed?

Nothing is going to change. You are running Windows Server 2003 Standard

Some says that it's because the BIOS reserves 512MB "physical" address
space just below the 4GB line and put the real 512MB RAM above the line.
Thus only the PAE kernel sees that 512MB RAM. 

This isn't a correct explanation of what you are seeing.

 

The BIOS doesn't reserve "RAM". PCI (and PCI-X and PCIe) devices can

Got a related question and observation.

I've a Dell 2950 with 4gig ram, Win2k3 R2 Standard and it show 4gig ram
in task manager, system properties and system info.

No /PAE in the boot.ini but it does show Physical Address Extension on
the system properties page.

Could it be that it auto installs some sort of PAE support if the system
has 4gig when the OS is installed?

Just curious.

Nothing is going to change. You are running Windows Server 2003 Standard
Edition x86. This has a built-in limitation (in the code) which prevents
Windows using addresses beyond 0xF

 

If you are using x86, put Enterprise Edition on there (with /PAE). Or
put x64 Standard Edition on there.

 

The limitation you are running into is hard coded into the OS.

Some says that it's because the BIOS reserves 512MB "physical" address
space just below the 4GB line and put the real 512MB RAM above the line.
Thus only the PAE kernel sees that 512MB RAM. 

This isn't a correct explanation of what you are seeing.

 

The BIOS doesn't reserve "RAM". PCI (and PCI-X and PCIe) devices can
reserve memory addresses. These overlap with addresses that the Windows
OS uses. The BIOS has masked these addresses, making the unavailable to
Windows to address the physical RAM.

 

The use of the /PAE switch enables three layers of page tables to be
used. If you are familiar with B-trees in databases, you'll be familiar
with the concept of tables of tables of pages of memory (3 layers).
Without PAE you only get tables of pages (two layers). The extra layer
of tables makes available a whole set of addresses that wouldn't
otherwise be available. These addresses can be used to address the
physical RAM that Windows can't otherwise get to.

I thought a 32-bit OS was limited to 3.4GB of RAM unless you use the Physical 
Address Extensions in the boot.ini file.  The file is a protected file in the 
root of C:\ (or whatever your boot partition is) so you will need to unhide 
protected OS files onder folder options.  Open boot.ini with notepad and add 
the /pae switch to the end of the last line (starts with "multi(0)

re: Myth: PAE increases the virtual address space beyond 4GB
Wednesday, August 18, 2004 9:05 AM by timchen
There is one thing quite interesting about /PAE. On some machines with 4GB RAM 
installed, Task Manager shows only 3.5GB physical memory. However, if you 
switch to the PAE kernel, all 4GB is shown.

Some says that it's because the BIOS reserves 512MB "physical" address space 
just below the 4GB line and put the real 512MB RAM above the line. Thus only 
the PAE kernel sees that 512MB RAM.

I'm not sure if the explanation is true or not, but the symptom is confirmed.

Dam, 

 

Cant put Enterprise Edition on the system it's a production dictation
system already customized and configured. 

 

I will try the /PAE switch, ( maybe to no avail) but I could have sworn
I have other 4GB of memory DL 380;s that show all 4GB with Windows 2003
X86. 

 

Again not being a subject matter expert on the memory ranges or anything
in windows you are talking a little greek to me when you talking the HEX
memory ranges.

Nothing is going to change. You are running Windows Server 2003 Standard
Edition x86. This has a built-in limitation (in the code) which prevents
Windows using addresses beyond 0xF

 

If you are using x86, put Enterprise Edition on there (with /PAE). Or
put x64 Standard Edition on there.

 

The limitation you are running into is hard coded into the OS.

I thought a 32-bit OS was limited to 3.4GB of RAM unless you use the
Physical Address Extensions in the boot.ini file.  The file is a
protected file in the root of C:\ (or whatever your boot partition is)
so you will need to unhide protected OS files onder folder op

Actually, I should correct this (I think I've had one too many beers
tonight) ;-)

 

If you are using a 32bit OS, you *must* use /PAE to get access to more
than 4GB of physical RAM.

 

The issue is if you are using both /PAE and /3GB and you are using more
than 16GB of RAM.

 

Are you using both /3GB and /PAE at the same time? If you are using an
/AWE aware application, then the application can move it's virtual
address space (the 4GB it can see) to different memory addresses. 

 

The use of /3GB causes the kernel to limit it's address space (to give
more memory to user mode processes), but because kernel memory is
limited, this then limits the memory that the Windows Virtual Memory
Manager - VMM - can use to keep track of memory pages, which in turn
limits the amount of memory that can be tracked by Windows.

as I found out) and when I got the OS to finally Boot ( DIMM 1A,3A must

BIOS shows 4096MB of memory on the boot, ( BIOS 4/6/2007), but when I

Checked the boot.ini ( there is no /3GB switch or

I thought a 32-bit OS was limited to 3.4GB of RAM unless you use the Physical 
Address Extensions in the boot.ini file.  The file is a protected file in the 
root of C:\ (or whatever your boot partition is) so you will need to unhide 
protected OS files onder folder options.  Open boot.ini with notepad and add 
the /pae switch to the end of the last line (starts with "multi(0)

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Ken Schaefer]

Some says that it's because the BIOS reserves 512MB "physical" address space 
just below the 4GB line and put the real 512MB RAM above the line. Thus only 
the PAE kernel sees that 512MB RAM.

This isn't a correct explanation of what you are seeing.

The BIOS doesn't reserve "RAM". PCI (and PCI-X and PCIe) devices can reserve 
memory addresses. These overlap with addresses that the Windows OS uses. The 
BIOS has masked these addresses, making the unavailable to Windows to address 
the physical RAM.

The use of the /PAE switch enables three layers of page tables to be used. If 
you are familiar with B-trees in databases, you'll be familiar with the concept 
of tables of tables of pages of memory (3 layers). Without PAE you only get 
tables of pages (two layers). The extra layer of tables makes available a whole 
set of addresses that wouldn't otherwise be available. These addresses can be 
used to address the physical RAM that Windows can't otherwise get to.

re: Myth: PAE increases the virtual address space beyond 4GB

There is one thing quite interesting about /PAE. On some machines with 4GB RAM 
installed, Task Manager shows only 3.5GB physical memory. However, if you 
switch to the PAE kernel, all 4GB is shown.

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Ken Schaefer]

I'll try to be a bit clearer:

/PAE enables 36bits *in the CPU* for storing page tables.

This does not *automatically* mean that your Windows OS will use 36bits for 
storing memory page tables. Windows XP SP2 (but not SP1) and Windows Server 
2003 Standard Edition x86, have an artificial limit *built into the OS code* to 
stop memory addresses beyond 0x (2^32) from being used.

/PAE is still *usable* on these symptoms (it enables 36bits for page tables). 
The NX (no execute) functionality that XP SP2 and Windows Server 2003 x86 SP1 
support relies on the extra bits that /PAE enables to store the /NX flag. 
However the artificial memory address limit in these OSes means you can't use 
addresses above 0xF to address physical RAM.

HTH

You can use /PAE with Standard Edition (/PAE is required to enable "no execute" 
functionality, for example - the bit flag used to indicate whether a memory 
page is not to be executed is stored in the extra 4 bits made available by 
/PAE).

However Windows Server 2003 x86 has an artificial (inbuilt) limitation that 
only allows memory addresses up to 0xF. If you use Windows Server 2003

It could be the PCI devices ( have a T1 Brooktrout Card, ATI Rage card

Address Extensions in the boot.ini file.  The file is a protected file in the 
root of C:\ (or whatever your boot partition is) so you will need to unhide 
protected OS files onder folder options.  Open boot.ini with notepad and add 
the /pae switch to the end of the last line (starts with "multi(0) 
disk(0)rdisk"... etc) and then reboot.  You should then be able to see all your 
memory.

Cheers,

Jeff

RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS

[Ziots, Edward]

Can we do the /PAE switch in Windows 2003 Standard tho? Usually only put
this in on Enterprise Edition. 

 

I am reading Raymond Chens post right now,

/PAE works no matter how much physical RAM you have.

 

But there is a good reason to remove it if you have more than 16GB of
RAM.

 

Review the Raymond Chen blog posts posted previously...

Microsoft Support actually had me remove the /PAE once I went over 16GB.
>From 4 - 16 the /PAE works but above that they told me to leave it off.

/3GB switch is for virtual memory (per user mode process, not
physical RAM)

To the list, and those using HP DL380 G5s. 

 

Ran into a strange one this morning. I have a pair of
DL380 G5's that I was adding 2 GB of memory to ( Have to add it in Pairs
as I found out) and when I got the OS to finally Boot ( DIMM 1A,3A must
match with DIMM 5A, 7A for the correct Advanced ECC configuration) the
BIOS shows 4096MB of memory on the boot, ( BIOS 4/6/2007), but when I
log into Windows I only see about 3.4GB. 

 

Checked the boot.ini ( there is no /3GB switch or
/Maxmem statements) 

 

Any ideas has anyone seen this before?

Explains why you can't see the extra physical memory without /PAE.

But Windows XP SP2 and Windows Server 2003 Standard x86 have an inbuilt 
limitation that restricts addressing to 0x and below.

Negative this is Win2k3 Standard Edition R2 SP1

OS only shows 3.4GB of memory ( msinfo32.exe or Winver or Task Manager) but 
BIOS shows 4GB.
