I have a 17" 2.6GHz MBP from the refresh around March of this year (the last refresh before unibody came out). I currently have 2GB (2x1GB) of DDR2 667MHz RAM and I'm going to upgrade to 4GB (2x2GB). Can I put in faster RAM? Will it improve performance noticeably?
Got a tip for us?

What is the fastest RAM I can put in my MBP?

Yeah, I know I can put 2x2GB of DDR2-667 in there. My question is if I can put anything faster than that, and if so, whether or not it will make a significant performance difference.
For example, there is this Kingston 2x2GB DDR2-800 pack for slightly more than your link. Will it run at 800MHz in my MBP, or will it be downclocked to 667MHz? http://www.newegg.com/Product/Product.aspx?Item=N82E16820134831
I think faster RAM will just clock to the bus speed. Check this thread: https://forums.macrumors.com/threads/536135/
Thanks for the link! My FSB is 800MHz, but according to that thread, DDR2-800 won't work with the MBP due to some timing issue.
Oh well, guess I'll stick with DDR2-667. Thinking about going for this Kingston pair since it's CAS latency is only 4: http://www.newegg.com/Product/Product.aspx?Item=N82E16820104033
I would trust This G-Skill CAS-4 set over your Kingston set just because of the more reviews available on it on Newegg.
Don't try putting faster RAM than 667MHz in your macbook pro, firstly it wont have any effect, yes it will downclock, and secondly i know someone who did that and shorted the ram docks and the logic board and then the main PSU, which meant his whole laptop needed replacing, luckily he put the old ram back in and denied any tampering while it was still under warranty.
