Core i5-470um never reaches to 1.86Ghz ?

Hi,
I got a new machine and testing it. I'm checking turbo boost monitor, however machine boosts at most 1.6ghz even in severe work load and performance tests. Does anybody know why ?

In "severe workload tests" it will load up all of the cores in which case it can only turbo by 2 bins bringing it up to 1.6GHz, it will only turbo upto to 1.86GHz under a load that only stresses one core.
