I'm running XP Pro 5.01.2600 SP3
Motherboard: Asus P5W DH Deluxe
Chipset: i975X
Processor: Core 2 Duo E6700 @ 2666 MHz
Graphics card: NVIDIA GeForce 8800 GT
Graphics card: NVIDIA GeForce 8600 GT

The motherboard manual says that 4GB may be installed with XP, but not all
will be
available for user space.
I realize that around 750MB out of the 4GB will be reserved for system
resources, and another 256MB may be taken by each of the graphics cards.
But that should still leave me with more than 2GB of user space?
I have seen reports by others who have successfully increased their user
space by upgrading memory to 4GB.

I have upgraded my memory from 2GB to 4GB, using a set of matched

During boot the BIOS correctly reports that installed memory is
4096 MB.

However, XP does not seem to recognize the memory upgrade.
The System Properties panel still reports "2.00 GB of RAM"
and the Task Manager says:
Physical Memory (K) 2096172

I realized that XP cannot get all of the 4GB, but I had expected to
get at least 3GB.

I have tried to set the /3GB boot parameter, but to no effect.

What is the problem?

Windows XP what?
What motherboard (make and model) do you have? (If a laptop - what
make/model do you have?)

Why are you running 2 graphics cards? 4 monitors? I would suggest remove one
of them and see if more memory shows up.
