Everest is correct in its PC3200 definition, that's what you got.
You can insert faster RAM in your PC, but it won'r run any faster than the PC-bus supports or allows.
Perhaps if you overclock, your faster RAM might come into play.
As long as it works correctly, you have nothing to worry about.
The most you have to worry about is that your CAS is of a supported type.
Most older Dell PCs e.g. only take CAS=2 RAM, and won't work with 2.5 or 3.
