8GB RAM installed, only 3.25GB usable?

Today I went to check my PC properties for some reason and saw that ony 3.25gb of my 8gb installed ram was usable.

My system specs are:
amd phenom iix4 965 BE
amd radeon 7850(MSI)
Asus m5a78l-m/usb3
2x 4GB sticks of Kingston RAM

How can I make the whole 8GB (or close to 8gb) usable.

Thanks in advance.

    Yes, I am using 32 bit. Do I need to upgrade so it can use 7GB or so?

    Just be mindful...32bit to 64bit is a full reinstall, not an upgrade.
