    I am trying to install new RAM for my MacBook Pro (13-inch, Mid 2009) and every time I start up my MBP with the new RAM all I get are the "3 beeps every five seconds" noise. I cannot figure out what is wrong (obviously).

    New RAM Specs:
    CORSAIR Vengeance 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800)

    Current Specs:
    Memory - 4 GB 1067 MHz DDR3
    Processor - 2.53 GHz Intel Core 2 Duo

    Your new memory is too fast. You need to use the same speed as the existing memory.

    I was able to get 1333 MHz RAM working in my mid 2009 13" MacBook Pro. Anything faster did not work.

    Definitely a YMMV situation. When I tried 1333 RAM in my mid-2009, it would boot but be very unstable.

    I am ordering new RAM and will find out if this fixes it. It sounds like it will.
