sukesh1090, the default ram speed supported by Phenom II/Athlon II series is 1333 MHz. You have to overclok the Ram Multiplier to make it work in 1600 MHz speed and there is no chance of memory controller damage or anything.
In my previous config, I used to run my 2X2 GB Kingston 1333 MHz value Ram to 1600 MHz speed by adjusting the multiplier to X4 from the BIOS of my Gigabyte GA-MA-785GMT mobo. Now all the current 8XX/9XX series mobo can detect the XMP profiles of ram. So if your Ram is a 1600 MHz ram, while plugged it will run @ 1333 MHz speed but the XMP profile can be accessed in Motherboard BIOS setup. Just select the profile for the 1600 MHz and your done.
