    Hello,

    How are you?
    I have a 2008 Macbook Pro 17 inch.
    It has the stock 4 gb of ram, in the form of 2x 2gb of 1066 ddr3 ram.

    I saw some ram from OCZ at a very good price, the OCZ3M13334G.
    It is a 4gb dimm, but it is rated at 1333 ddr3.
    I can get 2 of these, making 8gb for 150 euros, wich I think is a good price.
    The question is if it will work good on my macbook, being 1333mhz?

    Please help me out.
    Thank you.

    Best regards!

    RAM can run at a slower speed than advertised usually without issue. It's rated at the higher speed, but can function lower than that.

    Does that machine support 8GB though? You say it's a 2008, so I think you can only use DDR2 SO-DIMMS in those machines.

    A quick check of MacTracker shows that the early and late 2008's can only take 6GB of RAM (PC2-5300 DDR2 SO-DIMMS). You may want to do some research to find different RAM.

    I'm sorry, my mac is not a 2008 model, it is an early 2009.
    It is already the unibody and has ddr3 ram. It is this one:

    Will the OCZ memory at 1333 work nice and will it be a good upgrade?

    Regards!

    Are you sure it's 2008 MBP as 17" didn't support DDR3 until January 2009. 1333MHz should work but it would be downclocked to 1066MHz.

    Two chips clocked higher WILL NOT work in conjunction. 1 chip clocked higher with 1 chip at the correct rated speed will.

    Put both chips rated at 1333 and you will get to the grey screen with the Apple logo and then watch the circle spin forever.

    I recommend 8 GB of the PC3 8500 variety, same as what your computer came with. Newegg.com currently has a sale expiring today for 8GB of G-SKill for $159 rated for what you need. Good luck.
