I have a, i guess you would call it late 2008, mac book pro bought in feb 2009. System info from Geek Bench: MAc OS X 32 bit model: Late(2008) Processor: core 2 due t9550 @2.66ghz memory 4gb 1067 ddr3 my question is i want to upgrade the hard drive and memory. Sense i see everyone going for the ssd and spending tons of money, it not something i want to do for ssd. I just wanna go to a 7200rpm drive, but frankly idk what to look for and i dont wanna go back words in performance lol. Now for the memory i would like to do 6gb of memory sense i know the late 2008 macs can do 8gb but ill never use it all lol so 6 should be good. Now as you can see my memory at 1067 i would like to go 1333ghz with a good timing but i need some help sense i know macs are a little picky with memory. if it was a pc i would be able to help my self out on this one easily but with mac i dont want to waste shipping back and getting the right stuff. just wanna get it done in one shot. Either way i hope this makes some kinda sense, if not ill be more than glad to clear up anything i may of made confusing. P.s i would want to go with a 1333hz 7-7-7-xx but on new egg i only see the kingston hyper X and i saw that it would need the xmp memory file but i know macs dont have that sooo. is the 9-9-9-xx the same as the stock latance of the 1066 memeory?
