Newly installed SDRAM is only partially showing up.

Hi,

Sorry if this isn't precisely Windows related,

I just added two 1-GB sticks of SDRAM into my Dell computer to bring it up
to 4 GB, but it's only showing up under System as 3.25. Which is interesting.

My tower has four RAM slots. When I bought the computer it had four 256 MB
sticks (1 GB), two of which I replaced with two 1 GB sticks a while back
(2.5) and today I replaced the remaining two 256 MB sticks with two 1 GB
sticks to bring it up to 4 GB.

When I turned my computer back on, I was notified that my computer's memory
had changed, giving me the choice to continue or run setup. I chose to
continue.

I am aware that RAM has to be installed in a certain order and as far as I
know I did so, but 3.25 is a strange number. My specs are: Dell Dimension
E510, Pentium 4 3.0 ghz, Windows XP Pro. I bought the RAM off of the Dell
website.

Any advice would be appreciated. Thanks!

That is because WinXP 32 bit cannot recognize more ram than that.
Nothing wrong with your ram or your setup, it is just a operating system
limit.
If you go to a 64bit system, then more ram can be used.

Here is one reasonable explanation of what sounds like normal behavior
(a popular question though):

Some Google searches will find many others.
