No, but it doesnt mean you can do it though. You have a locked multiplier of 11. Upping the front side bus to 166mhz means your gonna run 11x166 =1826mhz which you chip probly cant handle. Unlocking isnt that hard if you have the right tools and its well worth the effort.
Here are some good articles on how to unlock your chip.
Edit: You can always run the memory asynchronous (133/166) from the cpu fsb but that would be pointless since it wouldnt offer any real improvements, what you want to do is them synchronously (166/166).
