just increase the fsb, if you encounter instablility increase the voltage. If your temps go over 55c full load back off. Your memory should allow you to push the fsb pretty far so that should be no problem, however i doubt your chip could take 166mhz fsb. I would shoot for 133mhz fsb that should leave you with a decent overclock.
BTW all of these settings are in your bios, re-read the manual normally they talk a little bit about overclocking.
