Windows 7 Professional only recognizes 16GB of RAM when physical is 24GB

Hey there,

Recently upgraded to Windows 7 Pro via the anytime upgrade, so I could take advantage of more ram on some video/photo editing.

After the upgrade Windows still only recognizes 16GB (although bios and CPU-Z recognize 24576 MBytes)
