I just bought some crucial 512mb pc2100 ram online, for my system, which currently has 256. Everythings all good and fine, and then Im just browsing through crucial.com, and it has a memory selector, where u enter ure compu. model and make and it gives u the kind of memory that will work in it. Well, this is after I ordered the other memory. And the one I ordered, and the one crucial reccomends are two differnt model numbers

. So, then I pulled up the model number of the one I ordered, and compared the sites side by side, and they are idenical under the specs.
There HAS to be something different?? Heres the links:
One I ordered:

One crucial reccomends for my system:

I would appreciate any help here guys
