Query: not for Macbook Pro mid 2008

Although I thought this was the same memory RAM advised by Crucial.com memory scan (http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=3FD44F41A5CA7304), I guess this was not the same one recommended by their site.As soon as I installed the RAM, my laptop makes two beep noises on the initial startup, which means that the RAM was incompatible to my laptop.I am returning this, and will try buying Crucial RAM from their site.This is my computer spec of my Macbook Pro mid 2008:Model Name: MacBook ProModel Identifier: MacBookPro4,1Processor Name: Intel Core 2 DuoProcessor Speed: 2.5 GHzNumber Of Processors: 1Total Number Of Cores: 2L2 Cache: 6 MBBus Speed: 800 MHzBoot ROM Version: MBP41.00C1.B03SMC Version (system): 1.27f3
