    I'm looking at NewEgg for ddr2 67mhz ram for my MBP and I see a "cas latency" of either 4 or 5 (mostly 5's).

    What should I look for when getting ram? Is there much of a difference between 4 or 5? Any other "features" I should look for?

    CAS 4 is technically slightly faster than CAS 5. I recently upgraded using the CAS 4 but that was only because there was a sale at the time and it was actually cheaper than the CAS 5. :) There is little to no practical difference between the two.

    You should try to get a matched pair as that will give you a slight performance boost. (Although not much.) Oh, and stay away from "value" RAM, most of the stuff is terrible.

    Edit: I'm pretty sure MacRumors has a guide to buying RAM someplace. You should try checking that out.

    ...stick with a major name brand with a lifetime warranty...crucial, kingston, corsair, etc... and you'll be fine.
