Re: X86 to 64 not using full potential

It's using all your memory. It's just that some of it is reserved for system
use.
It's working fine. Don't worry about it.
Don't get 64 bit Windows unless you have MORE than 4 GB of memory.

Not true.. It is using 3gb of the four available. The rest of the
addressable space up to the 4gb limit is being taken up by the motherboard
resources..

Not exactly. A 32-bit system has 4GB of *address* space, and some of this is
reserved for the system hardware. What remains is used for memory. You
cannot use more memory than you can address.

Not correct. Here's the correct info:

All 32-bit client versions of Windows (not just Vista/XP) have a 4GB
address space (64-bit versions can use much more). 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 can
range from as little as 2GB to as much as 3.5GB. It's usually around
3.1GB.

Note that the hardware is using the address *space*, not the actual
RAM itself. If you have a greater amount of RAM, the rest of the RAM
goes unused because there is no address space to map it to.

A crucial difference! Thanks for the clear explanation.
