    The difference is that the 667 operates on a faster bus speed compared to the 533 (667mhz as opposed to 533mhz). But however the 667 has higher Latency than the 533 RAM, so basically the speed difference is cancelled out (untill 667 RAM with faster timings can be produced), and some people have noted that the 533 is a little bit faster. But the reality is that you will not notice any difference in spped. Go for the one that's cheaper

    What are the specifications of your laptop? DDR2-533 vs. DDR2-667 - there is no difference in performance.

    There is a 3%-4% improvement between 553 and 667 but really not worth worrying over. Do shop around, I was able to get 2gb of 667 for $10 less than the 533 because of a sale.
