Those beeps mean that the RAM is damaged. First of all, check that the modules are correctly inserted following the steps of this site > http://support.apple.com/kb/HT1651?viewlocale=en_US&locale=en_US
If they are correctly inserted, the RAM modules are damaged, so you have to buy other ones. Depending on the MacBook model you have, you will have to buy one or another memory type. You can buy more RAM at OWC or Crucial

If you don't know which MacBook model you have or you don't want to change RAM yourself, take it to an Apple Store or reseller. If you want to do it yourself, first we need to know which MacBook model you have > http://support.apple.com/kb/ht1635

Jul 29, 2013 10:58 AMby mende1,As you have a Late 2009 MacBook, I recommend you to get RAM from OWC or Crucial > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_Whi te You can install 8 GB of memory.
If after installing RAM the MacBook still beeps, it's a logic board issue
