Usually, Intel motherboards have a option that allow you to change the maximum turbo boots setting if its available on BIOS, but we do not recommend this process since it will overloaded the processor and could damage it.
Please note that Intel® Turbo boost is engaged automatically depending on processor’s load, voltage, power and temperature. Therefore, at a particular moment the processor may reach 3.3 Ghz or 3.7 GHz depending on those variables.
