performance_maintenance >> [Vista Business] Not recognize 4GB Ram - SonyVaio VGN-SZ57N/C + Vista Business

by ADO. Inconnu » Fri, 23 Nov 2007 05:12:36 GMT

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. :)

I have the same problem. Does anyone here have a real answer?

Hi,

Not to be rude, but this has been explained so many times it is nauseating.
Please search this and other Vista groups before asking why:

I have a real answer for you since you only posted your question in one
single newsgroup. No 32-bit version of Windows will support 4gb of RAM,
this is a design limitation inherent in all 32-bit Windows versions. A
64-bit version of Windows is necessary to overcome the limit.

The other gentleman posted the same question in several newsgroups, which is
rude and increases the workload for those who are volunteering their time to
help out here, thus the reply to him.

This has been "covered" numerous times - Vista 32 bit does support 4 gig
RAM - it resrves "approximately" the "last" gig for specific resources such
as video cards.

Default Virtual Memory setting is 1.5 times installed RAM - checking Virtual
Memory will show a default setting of 6 gigs when 4 gig RAM is installed.

It supports a 4GB address space, but Vista cannot use 4GB of RAM due to
the address space reservations inherent to the x86 platform.

Sorry, this is not accurate. It uses " 'approximately' the 'last' gig"
of the 4GB *address space*, not of RAM. The problem is that that last
GB of address space is therefore not available to map RAM to.

4. Upgrade Vista Home Premium to Vista Business using FULL Business C 

My friend got an excellent deal on the FULL Vista Business CD when CompUSA 
was going out of sale. Since then, he bought a new Dell laptop with Vista 
Home Premium on it, and just wants to *upgrade* to Vista Business.
He does NOT want to wipe Home Premium to replace it with Business, since the 
laptop has all the drivers and MS Works (which he wants to upgrade to Office 
Standard 2007 using the "upgrade" version).
Can he use the full version of Vista Business to just upgrade Vista Home 
premium? As I recall, this wasn't always an option with older versions of 
Windows: if you had the "full" version on CD, you couldn't upgrade from it; 
you could only wipe and replace.
Thanks!

6. Vista beta2 64bit does not recognize all my RAM - 4GB 

Hi all. I just installed the Vista beta2 64-bit edition. I have 4GB RAM on my 
system and Vista only sees 2.5GB. I thought the 64bit system should be able 
to see all the RAM, that's why I ditched the 32-bit XP.

I have a Tyan Thunder K8WE motherborard (nForce Pro chipset) with 4GB ECC 
Reg RAM. Anyone got any ideas out there? Perhaps a BIOS setting that I need 
to change?

Thanks!

8. Action Pack Vista Business Upgrade dvd not recognized 

I'm trying to test the Vista operating system and I'm using the Action Pack 
upgrade dvd for the install.  Upgrade advisior told me I needed a dvd drive 
so I installed a new LiteOn dvd drive in my computer.

I verified the new dvd drive was working by making a data disk and copying 
files to it.  I also verified that it saw a dvd disk.  After that I decided 
to try the vista upgrade.

I put the Action Pack dvd in the drive and - nothing happened.  No upgrade 
screen, no files displayed in explorer - it just sat there.  I thought that 
there might be something wrong with the dvd so I put  it in my laptop's dvd 
drive and presto - the upgrade screen appeared.   I didn't want to upgrade 
my laptop yet so I tried the dvd back in my desktop computer.  Same story. 
I tried some other action pack dvd's.  Some worked some didn't.

Is there something special about action pack dvds that prevents them from 
running under certain conditions?
