Hi, I have a 2.4GHz 13" MBP with only 4GB RAM (using OS Mav) and I'm looking to upgrade it with more memory. I'm not too sure when it comes to the inner workings of Macs but I was wondering whether there are any special requirements for Mac systems in regards to RAM. I've seen some manufacturers that advertise RAM specifically for Apple and I'm wondering whether I really do need to pay over the extra premium for this compatibility, or will any RAM do (as long as it matches the speed). I know the 2010 2.4 is rated PC3-8500 (204 pin). My options is to either go for the following: Kingston 4GB ~$400HK(~$55-60USD) http://www.amazon.com/Kingston-Tech...=1408514514&sr=1-2&keywords=kingston+1066+mac Or will something like this work (but it's not stated for Apple use) G.Skill F3-10666CL9S-4GBSQ ~$200HK (~$25USD) http://www.gskill.com/en/product/f3-10666cl9s-4gbsq Specs: DDR3-1333 (PC3-10600/PC3-10666) 4GB (4GBx1) CL9-9-9-24 1.50 Volt Any help on this matter would be greatly appreciated.
