Are you running windows 64bit or 32bit?
To check on windows 8, search and open the 'System' application. From there you should see Windows 8 32bit/64bit according to your current version. 32bit only allows 4GB or RAM usage. Since yours has 3.11GB usable RAM, the other 890MB is most likely been used by your OS.
