he actual turbo listed is not what it will go to. The Turbo listed is the highest level of Turbo - on an FX8350 that would be 4.2Ghz, so a Multiplier of 21. The normal turbo that will run all 8 cores is 4.1Ghz so a Multiplier of 20.5, which will let me run 4.776Ghz with a 233FSB.
 Under a heavy load, the CPU will cycle between my set CPU Ratio and the Turbo Speed to run cooler. Or it will just stay at the set CPU Ratio - which is ~4.5Ghz

 So using this method I will have a 17% increase in Single Threaded Performance and a 12.5% increase in Multithreaded Performance.
 With the power saving features I idle at 68W. (Full System)
 At full load 280W which is the same as a Manual 4.5Ghz Overclock.
