Subject: Re: How to get new memory to work?
I am not sure. It came with four RAM slots, all filled with 512's.
After about a year I replaced two of the sticks with 1G sticks. Windows
picked these up without a problem. Six months later, the present day, I
replaced the second set. However, this time the new sticks were not
picked up. The configuration of the sticks before this last upgrade
was: 512-1G-512-1G. Now, the BIOS shows: 1G-1G-1G-1G, but Windows says
3024 KB.
Does this help you help me?

I had the same idea about my Dell but further investigation into the=20
computer came up with a maximum of 512 for my Dell model. Could that be
your=20
problem?

Subject: [PCBUILD] How to get new memory to work?
Is there anyway someone could tell me how to determine why Windows is
not picking up new RAM I just installed? I have a Dell Dimension 4700
that came with 2 dual 512 sticks. Later I put 2 1G sticks that Windows
picked up. I have now replaced the old 512's with 2 1G sticks. The
BIOS setup picks the new sticks up, but when in the properties menu
under My Computer, it shows the total from the old configuration. How
do I determine whether the sticks or bad or Windows is the problem?
Thanks,

This is apparently a limitation of the Windows 32-bit operating system. I
read somewhere that in XP, only 3GB will be seen but I can't find that
particular document again. I found several descriptions for this and there
are workarounds for Server Editions plus that limitation is not in the
Windows 64-bit OS. There may be some ways to perform tweaks within the
boot.ini file that will allow your PC to "see" all 4GB, and some suggestions
that with that much memory you could disable the paging file.
Microsoft says Windows XP can use 4GB, and your Dell says you can have it
(and the mobo supports the use of it) but Windows reserves a portion of your
memory for basic operations, so you'll never have access to all of your
memory in any case.
Here are some links to what I found:

On another note, what applications do you run that need 4GB of memory. Just
curious.
