I would surprise me too. I also run PC100 memory at 66 MHz with future upgrades in mind. > Please explain why you think PC100 shouldn't be in a 66MHz board.

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. HTH, Eric -- E.L. Meijer ([EMAIL PROTECTED]) Eindhoven Univ. of Technology Lab. for Catalysis and Inorg. Chem. (SKA)
