HI tortiz96, the Intel® Xeon® Processor E5-4650 has a default clock speed of 2.7 GHz and it can reach a maximum turbo frequency of 3.3 GHz. This means that the processor will use Intel® Turbo Boost Technology to increase the clock speed up to 3.3 GHz automatically and depending on temperature, voltage, power, load and amount of cores being used. This could mean that the processor will increase to 2.9 or 3.1 GHz at some specific moment and not necessarily reach the maximum.
Intel® Turbo Boost Technology is not the same as overclocking since the first one is managed automatically and it is not on-demand or user controlled as overclocking is. Only unlocked Intel® Core processors (which models end in K or X) can be overclocked.
