but the other measurement is the speed at which the RAM (any chip, for that matter) processes the information going through it.
There is a little info here - scroll down...
http://en.wikipedia.org/wiki/RAM
to "memory wall"...
I just upgraded my Macbook from 1 gig of ram to 4 gigs. Looking in the "system profiler", it says that their size is 2GB each, and that their speed is 667 MHZ. What does the 667 MHZ refer to? Isnt the size of the memory what determines how much performance you get out of the memory?
Thanks in advance!
