Sometimes RAM module makers skimp and don't include instructions for other speeds; that is, sometimes you'll get a chip that's rated PC133 that does NOT include EEPROM code for running as PC100. Rare, but possible. It's more common to get RAM that's spec'd to 2-2-2 that doesn't have EEPROM code to go down to slower speeds in that regard. This was the cause of the great Apple-firmware-update-disables-some-RAM fiasco. -- G-Books is sponsored by <http://lowendmac.com/> and...
