CPU Clock Usage

Hello,

Me and my mentor are using an Intel Xeon e5 v4 processor with 3.70 Ghz maximum frequency on Windows 10.
We are solving battery problem with heat transfer coupling.

As we noticed, while the simulation is going on, the CPU clock is fluctuating and barely hits up to 3.7 Ghz. It stayls mostly around 2.7 Ghz.

Is there any way to use the CPU at the maximum clock speed?

Thanks

Erdem
