    Hello, I have a 2009 white unibody macbook 2.26 GHz and i want to upgrade it to 8 gb of memory. Every official site said my macbook can only go up to 4 gb, but i see others upgrade their macs (the same model) to 8 gb ram. Can you tell me if i can use these modules for my mac.

    You can find specs on all Apple products, including maximum RAM:
    • By visiting EveryMac.com: Actual Maximum RAM
    • By using Mactracker
    • By entering your serial number here to find specs for your model. (Be aware that some models can use more RAM than Apple shows. Check EveryMac or MacTracker to verify.)

    That memory looks like it is too fast and MacBooks don't run their memory at lower than rated speeds. The end result is that your MacBook probably won't boot up until you replace one of the modules with a 1067 speed *or* manually edit the speed of the module via software so it reports itself as a 1067 speed.

    However, you can also just buy something like this http://www.crucial.com/store/partsp...067&AID=10273954&PID=4169666&SID=ywmrs4k0zuek that is the correct speed rating for a similar price (actually cheaper disregarding the rebate process at Fry's). You can also check amazon.

    I don't have the packaging of my 8gb setup in front of me so I can't tell you the exact memory I am using for my MacBook 6,1 but it is either the one I linked or something similar.
