Is this a Socket 7 board? Are we talking about DIMMs? If so, very few Socket 7 boards liked PC100 memory, I never heard of any resolution to the problem of incorrect memory size detection except using PC66 memory. > ps - the PC-100 RAM is probably 70ns, yes? If we are talking about SDRAM then no, it's a different technology. Typical access times for SDRAM vary from 8ns to 12ns, lower being better, usually you don't have to worry about this since most SDRAM has a small piece of ROM on it that tells the board what settings should be used with it.
