Hi,

It occurs because the 32-bit versions of Vista have only 4GB of address
space, and some of these are reserved by the system for addressing the
hardware. The remainder of available addresses, usually between 2.7 and
3.3GB, are assigned to the memory space, so this is what you see reported as
available.

That's because some of that space is used by hardware and not
available to the operating system and applications. The amount you can
use varies, depending on what hardware you have installed, but is
usually around 3.1GB. You got a little more than the average.

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.

It is a limitation of a 32 bit operating system. You get 4 GB of addressing
space, and your video card, i/o, BIOS, etc, take up some of that. What's
left over gets allocated to your RAM.
