When the AMD Phenom II X6 1090T processor was running at full load the multiplier jumped up to 16 and the overall clock frequency is now 3.21GHz, as you can see from the screen shot above. This is what happens when a heavy load is on at least four or more threads.
When the AMD Phenom II X6 1090T processor is under a light load on just three or fewer cores the multiplier jumps up to 18 for an overall clock frequency of 3.6GHz. This is how AMD Turbo CORE technology works. It's not as complicated or efficient as Intel's Turbo method, but it works and is certainly better than not having it!
