    Hi everybody,
    Today I was browsing Newegg looking for some new ram, when I came across a strange comment. I have a late 2009 MacBook I'm looking to upgrade the RAM in. It takes DDR3 1066MHz PC3-8500 RAM. Someone in the comments said that a computer that takes that can except DDR3 1333MHz PC3-10600 RAM, and I didn't know this. Is this true? If it is, I would love to get faster RAM.

    Go to Crucial.com, and input your machine. It will tell you what is compatible. Just because a RAM is faster, and will install, doesn't mean your machine will be able to take advantage of it.

    I installed 2 x 4GB 1333MHz Corsair RAM in my mid 2009 MBP(same CPU and nvidia MCP79 chipset) and it actually runs at 1333MHz. It's worth a try. It's cheaper than the 1066MHz stuff anyway.

    Just make sure you read through the reviews to verify that other Mac users are able to get it working in their models.

    I have a late 2009 macbook and i also installed 2 x4GB 1333mhz Patriot ram modules in it. apple recommends the max is 4GB in total running at 1066mhz. it seems to work ok i wonder for how long though
