Usually it's NEVER a good idea to mix and match bus speeds on RAM. And it's usually not a good idea to use speeds slower than the specified amount for your machine. How old is your MB? Please visit the link for more information: http://guides.macrumors.com/Understanding_Intel_Mac_RAM
...the faster RAM will downclock to the speed of the slower RAM giving you no speed benefit execpt the fact that you have 4Gb of RAM installed...
What is the supported apple "max" RAM for your machine (2 or 4Gb)?
If I recall correctly, that model will only "see" ~3Gb of 4Gb RAM installed...
