mmm interesting, i did look on crucial's site but went with comp model not mobo model, which seems to be better, ok, so is PC3200 backward compatible then ? presume it will just run at top spec of mobo i.e. PC2100 ?
Crucial WILL guarantee that memory they say will work, will work, or they will exchange it.
In practice, whether faster RAM will rum successfully at lower speeds depends on the RAM, and on the motherboard. Timing specifications for faster RAM have less tolerance then for slower modules, and the motherboard may not be up to it (or it may).
The worst situation, though, is that you fit RAM that actually does work, but gives strange intermittent problems over time.
So - whilst it may work fine, IMHO I always recommend to fit RAM that agrees with the board manufactuers specifications.
