Hi there, this is a question about RAM for my mac book but it's a general ram question, so i thought it belonged here
I'm looking at memory for my macbook and on newegg.com they had 2 types of RAM and the only differences seemed to be the speed.
one is DDR 667 with a CAS Latency of 5
one is DDR 533 with a CAS Latency of 4

from what i've been able to understand the first one would handle muiltiple bits faster, while the second will access the first bit of a job faster, then the successive bits will be slower.

so, which one is more likely to make an overall difference performance of my macbook (2ghz model)
