Accordint to Total Physical Memory 4,096.00 MB, I think it's normal.
As far as I know, Virtual Memory should equal to paged file.

About:

Windows Task manger
Total 2096616
Avail. 1706756
Is it in the "PHYSICAL memory" section?

Try  Process Explorer instead of task manager:
http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

And try start -> run, type "dxdiag", and check again.

Yes this is the "Physical Memory (K) on the Perfomance Tab in Windows Task Manager.

As for dxdiag, here is the sytem info:

Really strange that "systeminfo" command & task manager report different memory size, maybe you should contact microsoft for help to find out why this happens.

As for Processor Explorer, you can check memory by clicking "View->System Information(Ctrl+I)".

Two more suggestions:

Check if BIOS->Main can recognizes all 4G memory as POST shows.

Try CPUZ, a hardware detecting tool: http://www.cpuid.com/cpuz.php
If CPUZ also detect 2GB memory, paste Chipset & Memory SPD section of registers dump file(About->tools->registers dump) here.

>Thanks for the reply. Sorry it took so long for my reply but was busy moving into a new apartment.

I went to the Nvidia site to check for updated drivers, there auto scan system tells me there is a new driver:
nForce Professional Driver Version 6.70
Version: 6.70  WHQL
Release Date: March 8, 2006
Do you think i should install it?

Bios->Main shows

Hi ,

 

As you are running an 32bit os you will not see the complete 4Gb.

32Bit can address in theory 4GB memory. every device will use a part of this memory space. so a typical configuration should see about 3-3.5 Gb in windows.
This still does not explain why you only see 2 or you should have a lot of memoryspace consuming devices installed.

You should try with a 64bit os an see if you see the complete 4gb , if this is the case then you are just running out of 32bit memory space.

>Thanks for the response Neo,

I have tried everything i know of to get windows to recognize more than 2 gigs but nothing seems to work even tried the microsoft forums and nothing.
@ post it sees the 4 gigs
under system properties it sees 4 gigs physical but available physical is just under 2 gigs.

I am currently running
nvidea 7800gt (256mb) video card
ATI tv card

Also, I have updated all of my drivers; chipset, audio, video, bios since they have not been updated since 2004.

I posted here because i wasn't getting anywhere with microsoft so i thought it might have something to do with a bios setting. Somewhere I read but cant remeber where that XP will use the 4 gigs even though it does show it.

Currently DEP is turned on for windows program and services only ... would enabling it for all programs help?

Thanks

well if you are running a 32bit os you should set the bios to the same ( memory reallocation or something like that )

If you are running 64bit your should enable it , 32bit  disable. with 32bit your really wont get more than about 3.2Gb

you can have a 32 bit with memory reallocation on but it will not user the complete 4Gb.

HI,
When using 32 bit windows and looking for stability, you should, in my humble opinion, not use the  memory hole remapping in the bios or the  different switches (ex: /pae switch) in the  Boot.ini file.  I have tried it all ( I have 4 gb of memory (1gb x4). and  system uses 3,25 gb of ram (with a 256mg video card).

The problems you are having could be dew to the fact that you memory is not identical (but that would probably show up in the bios) and give all sorts of stability problems.  Try using sticks in A1 and A2 and B1 and B3 A3. just to see if things are changing. (or try A1 A2 B1 B2 with one cpu).

But I think the best way to get thinks working would be to reinstall Windows from scratch.  That would probaly solve all your problems.   And if you really need more than 4 gb of ram... go with linux :) or wait for Vista 64 to be properly supported by the industry.  That should happen around the time are computer will become obsolete! 

Good luck
