Technically/specifically, no. But in principle, here's an analogy that might help...
Assume you have a Mustang with a manual 5-speed transmission. You take off from a stop sign in your local town/city (speed limit = 35mph) in '1st gear'. Depending on your gearing and other factors, you might be able to just stay in 1st gear at 35mph, but your engine will be revving higher (high rpm) than it needs to be and 2nd (or even 3rd) gear may be more appropriate. By the time you hop on the interstate/highway, you're going to want to be rolling along in 4th or 5th gear.
...the analogy may not be exact, but my understanding is that there are sets of operating parameters that the mb uses, based on the 'strap' (gear) of the cpu... you can probably run your '800 strap' cpu up past 1066, but it's better if the set of parameters used changes to the '1066 strap' at that point and then again at the '1333 strap'.
