Ibook Sodimm

Can you use PC133 Sodimm ram in an Ibook G3 500 mhz?

I have an Ibook g3 with 256 MB of ram. I know that it uses PC100 ram. Is it possible to use PC133 Sodimms in my Ibook G3 because it is easier to get ahold of that speed. Specifically a 512 MB stick of ram. Thanks!

The PC133 should slow down and run at PC100 speed.
