I have Late 2009 iMac (http://support.apple.com/kb/sp576) but don't have memory 
As I am not able to get any 1066 ram module if I put this memory: http://www.kingston.com/us/memory/search/?partid=KVR16S11S8/4
Will it degrade Mhz to 1066 and work fine?
And one stupid question I can put 1 module inside iMac I don't need others (for now)?
