    I was surprised to notice the memory in my Pro is 1066, not the 1333 memory. If I swapped the memory with the faster spec, would I really notice much difference? I'm thinking that while it may perform better, it wouldn't be worth the effort even at a low price.

    Another part of me wants the fastest stuff! Which part of me is right- the speed demon or the cheapskate?

    Many thanks!

    The recommended memory for your Mid-2009 MBP seems to be 1066 MHz RAM. Not sure why you would want to used 1333 RAM.

    Yes, sorry, I had looked up the wrong one first, and then forgot to fix the date. Still, 1066 is recommended.

    From what I understand, your computer can't even utilize the faster RAM so it would just be downclocked to 1066 anway. No real point in getting the 1333.

    I use 1333Mhz RAM in my Unibody MacBook (It had 2GB and I had an extra 4GB from my MacBook Pro) However, the system bus speed is reported as 1.07GHz, therefore the extra speed cannot be utilized. It won't hurt by any means however, it's just not cost effective if you're paying more for it.

    Thank you all! After I posted, I did see the bus speed and realized the machine had the correct RAM installed.
