I would surprise me too. I also run PC100 memory at 66 MHz with future
upgrades in mind.

One thing that may be important to watch out for is that some older
motherboards need physically different dimms. We have a dual PPro with
an Intel mobo, which apparently needed special (read: rare) dimms with
the `nudges' in different places than where they are in the current
dimms. The current dimms simply don't fit in the mobo.
