PC100, and PC133 questions

[ChemicalAgent]

While ordering the parts for a new rig, I accidentally ordered a stick of PC100 Crucial ram. I meant to get PC133, but I didn't realize there was a difference in the listing of memory that was compatable with my mobo. I have an Asus CUSL2-C, and a 800EB PIII. Will the ram speed knock the system bus from 100, to 133? And will I see much a performace difference? Is it worth the hassle to return it?

Thanks.

While you can run the FSB and RAM synchronously on the CUSL2, ie FSB at 133 and RAM at 100, it does take a hit to performance. I think you should return the PC100 and get PC133.
