Hi JD,

I don't have any direct experience with DDR RAM, but to the best of my=
 knowledge it works similarly to the way standard SDRAM works. As you say,=
 if you want to use your current RAM along with a new module, they both=
 have to be PC2100. If you want to replace the RAM entirely, it depends on=
 what your computer is designed for but the safest is to say that the same=
 speed or slower will work in your machine. Now AFAIK, 2100 is the slowest=
 rating for DDR so my *guess* would be that no, you can't upgrade to faster=
 DDR RAM. What kind of motherboard do you have?

Hopefully someone else here may have a better, more solid answer for you.
