I was purchasing some memory recently for a system that currently has PC100 memory in it. I was going to purchase the PC133 memory as I have typically done in the past when purchasing new memory for a PC100/133 slot. Anyway, the salesman proceeded to tell me that PC133 memory will no longer work with PC100 due to some changes to how PC133 memory is now made. Is there any truth to this or did the salesman lead me down an incorrect path? This was news to me.

Thanks,
