32-bit Windows only has the capability of addressing 4GB worth of addresses. Since some of those are used by your hardware, the addresses become unavailable to use for addressing RAM.

Some motherboards also have a similar restriction, meaning that on them, the addresses won't be available even with 64-bit windows versions. These cases are rare.

Also if you have a "built-in" graphics chip - this may use some system RAM for graphics use - making it unavailable for general use.

thanks lads. Read it--don't pretend to understand it though but have taken from it that 3.2 is normal and I have to live with it.
Thanks again.
