No. See the table in the link and find the edition of Windows in question.

I just installed an additional 4GB totalling 6GB and System Properties and
the Task Manager reports 3.25GB, but in System Information does show the
total RAM.

My total RAM is available correct? Even though the other two info only
reports half?



All 32-bit versions of Windows (not just XP) have a 4GB address space.
That's the theoretical upper limit beyond which you can not go.

But you can't use the entire 4GB of address space. Even though you
have a 4GB address space, you can only use *around* 3.1GB of RAM.
That's because some of that space is used by hardware and is not
available to the operating system and applications. The amount you can
use varies, depending on what hardware you have installed, but ranges
from about 3 - 3.5GB-- usually around 3.1GB.

Note that the hardware is using the address *space*, not the actual
RAM itself. The rest of the RAM goes unused because there is no
address space to map it too.
