You already are. Some of the 4 gig is used by other cards. How much
depends on what you have in the system. Check out the MS Knowledgebase.

You got what you are going to get: 3.25 GB usable by the OS out of 4 GB.
This is a known restriction of the 32-bit Winduhs OS (and the Intel
architecture), caused by the fact that some of the 32-bit address space
is used to address non-RAM locations, such as I/O registers.

Not an accurate answer.

It is not the extra memory itself that is used by the other cards. It is
the memory addressing range that is used. Thus the memory above 3.25 Gb is
not available to the operating system because the address is used by
something else. 3.25 Gb available is about the average (it varies typically
between 3.1 and 3.5 Gb).

I believe the 32bit version of XP will only use 3Gbyte. Even though the bios
can see the full 4Gbyte I think the config you have is the best you will
get.
