Welcome to the forums!
While your CPU is
very a capable overclocker, nearly all Intel original motherboards have their BIOS' locked and are unable to overclock.
There was an article a few months back, The Best Overclocking Software
, that has a few software solutions you may wish to explore. Odds are, however, you will need a new, non Intel original, motherboard in order to overclock. If you can, exchange your current board for an ASUS or Gigabyte alternative.
