I assume you mean FSB.
The answer, generally, is no.
PC2700 is rated to 166MHz. It is guaranteed to work at 166MHz. Because
there is a variation in the quality of components, there is generally a
margin of error built in, to be sure that a certain percentage (usually a
very high one) that they will work at 166MHz. This means that instead of
designing them for 166, you might design them for say, 175MHz. And you
might find that 30% of them reach 185, and that 5% reach 195, and that 2%
reach 199MHz (I'm making these numbers up, I would suspect them to follow
something like a normal distribution).
So the answer is that you can almost certainly run them at more than 166MHz,
but how much more depends on a lot of things, notably surrounding quality.
