Which laptop memory is Faster and Why? Option 1 or Option 2?

Question

Option 1:
DDR2 PC2-5300 • CL=5 • Unbuffered • NON-ECC • DDR2-667 • 1.8V • 512Meg x 64
Option 2:
DDR2 PC2-6400 • CL=6 • Unbuffered • NON-ECC • DDR2-800 • 1.8V • 512Meg x 64

Many thanks,

Andy

Answer 1

Option 2 is faster, but if your computer memory bus is only running at 667 or below, you won't see any difference.



Best bet is to use matched pairs of memory,

Answer 2

Option 2, because the RAM runs 800mhz while the other one is lower.

Answer 3

Option 2. It's 800Mhz instead of 667Mhz.
