Using 8gb of RAM on 32-bit Debian web server


We are currently running a Debian web server that physically has 8gb of RAM installed in it but is only showing it is using upto 4gb of it. I believe that the reason for this is because it is a 32-bit operating system and therefore can only utilise 4gb of RAM by default.

Can anyone explain if and how we can use the full 8gb of RAM?

Thank you for any replies.
