According to your SS, CpuFid is always 6. It means 2200MHz speed. But somehow AOD reports lower clocks. To be sure, you can use CrystalCPUID and its speed measurement function. It has various ways to measure speed, try all of them and see if they are all the same. Pref F5, F6 .... F9 and see what happens. My point is to determine who is wrong since AOD displays lower clocks and CPU-Z displays higher clocks.
