I'm trying to look up which RAM my friend needs for his Macbook pro. If I go to about this mac it says - 2.16 ghz intel core 2 duo, 1 gb 667 mhz ddr2 sdram. I believe he can max this notebook out at 4 gb. Would this ram work? http://www.newegg.com/Product/Product.aspx?Item=N82E16820134560 I know it's a good brand, and that seems like a great price for 4 gb. Help please! thanks.
