You are good to go, the fastest supported ram for that CPU would be 1866mhz, you have 1600 mhz which is also compatible. Make sure your motherboard can handle 1866 as well.
Edit: Don't worry about that compatible thing that lists names, there are power supplies that state compatible with Phenom II but in truth they work with all processors. It's more so the specs of the ram that needs to be checked. For example if you bought this processor that supports only 1333mhz ram and you buy 1600mhz ram then don't worry since it will downclock itself to 1333mhz.
