    Question Prof Messer:u00a0 If I’m following, the memory speed example for SDRAM given in the first vid above (PC133) refers to the speed of the memory as well as to the speed of the FSB… they need to be the same to be “synchronized”.u00a0 Is that correct? (or even close? :) )nJames

      Correct, with synchronous RAM, the speed of the RAM must match the speed of the bus where it sits.
