If you now have 4GB RAM (2x2GB); most likely your OS is 32bit so it can`t use more than ~2.8GB of memory. You need to install 64bit version of the OS so as to use the whole memory.

Alternatively, you can try the following so 4GB RAM can be used on 32bit OS:

1. Open C:\boot.ini file with Notepad.
2. Replace the following:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" 
/NOEXECUTE=OPTIN /FASTDETECT 

...with this:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" 
/NOEXECUTE=OPTIN /FASTDETECT /PAE 

3. Save the file and reboot. You should now see 4GB of RAM in Task Manager & System Properties.

Maximum memory is 4GB, but as above 32bit will not read all the memory...

I`ll write back later if I find some patch for your OS. Otherwise, you`ll have to install 64bit version..

EDIT: Sorry to say, Windows XP can't see memory that is moved above 4 GB boundary, so however much "address space" (from 0.5 GB to 1.25 GB) is needed for peripherals is taken from that 4 GB range, and there is nothing to be done about it (except upgrade to a 64-bit operating system).
