Windows and my BIOS saying 4GB RAM, CPU-Z saying 6GB.

I have 6GB of DDR3 RAM installed. However, when I went into the system properties in windows, it said I only have 4 GB RAM.
Thinking this was strange, I checked CPU-Z which tells me I have the correct amount, 6GB.
As a double-check, I rebooted my system and went into my BIOS, which also tells me I have 4GB.
What's going on? I'm assuming since my windows and my BIOS are only detecting 4GB RAM, that only 4GB is being referenced.

Thanks for any help,

Spazman0.

Check in the BIOS if exist an option that says "Addressable memory" or in msconfig too.

There is no option for addressable memory in my BIOS, and the option in msconfig is turned off.

The only thing related to my RAM that is in my BIOS is that it says "Installed Memory: 4096 MB"
