 |
|
With 2gb sticks of kingmax ddr400, vista32 seemed (*) to work fine. Added a
3rd stick of kingmax about a month later when we also upgraded an intel
d865perl mombo.
Memory was posted at 2.6gb not 3gb with 512mb agp aperture. System reset
during vista boot.
Decreased agp to 256 and memory posted to 3gb (correct amount) but system
still reset during boot.
Installed 1013 bios (we had 1012) but it didnt make any difference.
System has 3000mhz semperon (2x166 cpu) memory at 2x200 (using spd setting).
Tried crucial memory didnt make a difference. Pulled crucial from an intel
d865perl that had a similar problem with vista32 and 4gb. Put crucial back.
Not sure what the problem is, since max memory is 3gb there should be 1gb
left over for the video board (256) and agp address space (512 or 256 or
whatever??).
OK, I read a discussion on intel web site that 4gb address must include 2
times the agp aperture plus the on-board memory of the video card. So I see
where the 3gb showed up correctly when we selected aperture of 256 (instead
of 512) since 2x512 leaves no room for video memory.
We got the d865perl to boot with a pair or crucial 1gb each and a pair of
"dell" at 512 each. Even with latest bios on d865perl (p21) 4gb was only
seen as 3gb irregardless of the aperture setting. Think this is a chipset
limit both a7n8x-e and d865perl.
Wondering if anyone got 3gb to boot on that E Deluxe with vista32?
* everything works fine on A7N8X-E Deluxe under Vista 32 except an old USB
(v)1.1 memory card "8 in 1" is no longer recognized.

A lower AGP aperture may still be viable, for testing purposes. Maybe
you could try 64MB for example. Just to test your theory.
Well, this says 32 bit Vista will not report more than 3.12GB of memory.
(I don't know how many times I've wished for an application that can
draw a memory map of the system...) So this is probably not a chipset
limit. Maybe in a year or two, a technical article will describe where
"3.12" came from.
http://support.microsoft.com/kb/929605
And this one suggests disabling USB on Nforce2.

It looks here, like installing Vista is a "mystical journey". They
changed modes on unused controllers, to keep them happy. I.e. An *unused*
RAID controller will work, if it is set to vanilla IDE mode. Looks
like some voodoo is involved.

And this thread has some stuff on trying to use 4GB (most of the posts
are about 64 bit Vista).

Even if it doesn't cure your problems, you may get some entertainment
from reading the posts on that forum.

WindowsXP and Vista 32 bit cannot address anything above 3 GB memory
because they don't support PAE: Physical Address Extension, which
WindowsXP x64 and Vista x64 can. It's a 32 bit OS limitation. |

Hmm. I looked this up and found the reference
http://www.microsoft.com/whdc/system/platform/server/pae/default.mspx
From what it says there, 64bit xp and 64bit vista do not support PAE, (they
do not need ths feature) it is only for 32 bit operating system.
I was not aware of any of this in particular that the commmand /3gb needs to
be in the boot.ini file for xp in order to an app to use more than 3gb
http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx
Where I work we occassionally have need for a single app to address large
amounts of data (3gb and higher) and have always used linux and a "big fiz"
model..
The system one of my sons have had 3gb of memory (pair of 1gb, pair of 512)
on a d865perl. That works fine with a 256mb agp aperture and his 256mb
gameing video card under vista 32.
I would think that viista is addressing the agp aperture (maybe 2x256) in
addtion to the agp memory which I assume is shared.
According to an intel specification update, the d865perl address space (4gb)
has to set aside 2x the agp aperture. One would think that vista32 must be
able to address 3gb + 512mb for this to work.
ftp://download.intel.com/design/motherbd/rl/C4159609.pdf
I am not sure where the 2x comes from nor if it applies to asus mombos with
amd processors (like the a7n8x). When we did boot the d865perl with 4
sticks of 1g the bios post showed only 3gb total even though the bios
showed 4 sticks of 1gb. In addition, vista32 only saw 3gb of memory. The
system actually booted and worked ok (unlike the a7n8x) but it was a waste
of memory so we put in a pair of 512 and moved the leftovers to another
system.
thanks for posting about the PAE, i was unaware of that and it explains why
the other programmers here have chosen to use linux instead of embedded
windows for our production systems.

Followup on this 3gb problem: I tried a 512 and then a 256 mb stick in the
3rd slot (in addtion to the pair of 1gb) and vista32 would not boot. I
changed the apeture down to 64mb before giving up and getting rid of that
3rd stick of memory. The stick was recognized and did pass memcheck and
posted, but vista32 consistenly rebooted or blue screened. Looks like 3gb
is max on this asus board. An intel d865perl handled 3gb ok on vista32.
We also changed from SPD to AUTO so that the memory ran at 166 (same as the
sempron FSB) and that seemed to stabalize the system which occassionally
hung playing call to duty at 200 and 166 respectively. This was noticed on
XP-Pro and when we upgraded the bios the memory went to SPD. It had to be
set back for stability.

XP and Vista 32 bit cannot address anything above 3 GB (3.12 to be
technical).
XP x64 bit and Vista x64 bit will address more than 3 GB, but not sure
what the limit is.
Here's a typical question and answer regarding the problem:
