I bought my SonyVaio Notebook Computer (VGN-SZ57N, with 1GB of Ram) coming
with an Vista Business installed, I can't work with its poor performance, so
I bought / installed another new 4GB(2x2GB) Ram to replace the original 1GB
of Ram(Product Spec. told that it support 4GB of Ram). As a result I
realized both the Bios and Vista the OS seeing only 3GB(actually 3070MB)
Physical Memory. I google around and I heard about Hardware's lacking of
remapping feature and Software's 32 bit OS limitation issues, but I hope I
still can hear someone here told me that this is an deadend for getting my
current computer to see and work with 4GB of Ram.

Please let me know whether this is a motherboard limitation or this is a
matter of 32bit versions of Windows, any explaination... Thanks so much for
your kindly help, I just felt sick of keeping search on this topic and I
think I can accept all of this if this is a matter of time (People told me
SP1 could solve all of this) or money (They told me I should upgrade to
64bit Vista Ultimate to work 4GB Ram). Hey, anyway thanks again, have a nice
day. :)

Hello ADO. Inconnu,

For the BIOS check the vendor support why it does not recognize the full
4GB. To get in Vista full 4GB, you can use the 64bit version, otherwise like
you say it is not possible by design to get full 4 GB.

The most any 32 bit address register can take is 4 GB so the limit is
set by the 32 bit OS and / or 32 bit hardware. Video and other things
take up some of the address space so whatever they use cannot be used by
the OS. There is nothing you or anyone can do about this, including a
service pack. It should not do any harm, just seems a bit wasteful,
however you did the best thing by using all the same RAM, it can be a
problem using mixed versions and you should get the best you are going
to get from it. Make sure you visit the makers' website to get latest
drivers for all chipsets and components, that may improve speed. Some
drivers that ship on new machines are not exactly the greatest.

Sadly, if BIOS only sees 3GB of memory, there's not much else to be done.
Unless and until BIOS sees it all, it won't matter what you do - if BIOS
cannot see it then Windows cannot see it either.

Heh, I missed that, maybe a BIOS upgrade would "See" a bit more but that
is always risky - a few times now I have updated BIOSes to find the
update sixes one thing and breaks another, and it could be terminal for
the motherboard. I still think though it is better to have bought 2
sticks from same place at same time rather than risk mix and match...

Not a 'dead end' at all - only with MS. Linux 32 bit systems will
recongize up to 64gb.

Makes sense. Linux counts differently. Base 3.5 or something.

2**32 = 4,294,967,296

2**36 = 68,719,476,736

By default, most 32-bit Linux kernels address 4GB of memory. You can
configure the Linux kernel to use Intel PAE (Page Address Extensions) to get
36 bit addresses; and hence access up to 64GB of memory. However this extra
memory is not a free gift. Executing code can't run in memory above 4GB,
even when the OS can address that memory. So application code must continue
to live below 4GB. Also, to be directly manipulated by code, data needs to
be moved from the High Zone (> 4GB) back down into the Normal zone, with a
kmap() or similar call. So, even if you have PAE and 64GB memory enabled, it
won't be any use unless your application is PAE-aware. The memory above 4GB
is mainly useful as cache, for example if you have a database application.

Windows Server 2003 offers the same 64GB facility, by booting with with the
"/PAE" switch; and by using AWE memory APIs in your Windows applications (eg
as in 32-bit SQL Server). The limitations of 36-bit addressing on Windows
are similar to those on Linux. The 32-bit Windows Server 2003 Enterprise
edition can address 32 GB of memory (via PAE). In SP1 this was increased to
64GB. Windows automatically enables PAE on CPUs with the DEP feature. Since
most new CPUs are 64-bit anyway, all this memory jiggery-pokery is
fortunately going away ...

The system memory that is reported in the System Information dialog box in
Windows Vista is less than you expect if 4 GB of RAM is installed:

Dude, it's a dead end if BIOS only sees 3gb. Pray tell, how will Linux fix
that for him? And if it will, will it fix my old Celeron laptop by turning
it into a dual-core powerhouse?

You obviously know nothing about Loonix. See the function:

f'(x) = imagine(0)+pretend(1)

Ah - sincere apologies, and thanks to you for setting me straight. ;-)
