Q: 3 Beeps Reinstalling OS in 2009 13" Macbook Pro

Recently on my 2009 13" Macbook Pro the hard drive failed so I replaced it. I don't have the original OS disc but I do have a retail Snow Leopard copy. When I boot to the disc it load then just begins to beep in groups of 3. After much research this usually means a problem with the RAM but I haven't touched the RAM. I did read somewhere that I need the original discs because of a system patch or something but I have no clue. Any help would be appreciated. Thanks!  

MacBook Pro, Snow leopard
