The speed rating of a memory module is its tested maximum. It can go slower
and might even go faster, but cannot be guaranteed stable if run over its
rated speed. Its like a car that is claimed to do 120MPH. It doesn't have to
go flat out. It might go faster (down hill with following wind), but you
might damage it.

I think DDR2 is a different physical size though, so won't work.
