1. A method for managing overclocking in a data center, comprising:
determining a frequency limit of a first processor of a first server in the data center;
modifying a voltage of the first processor to a lowered voltage by lowering the voltage to a stability point;
modifying a frequency of the first processor to a lowered frequency limit by lowering the frequency limit based upon the lowered voltage;
testing the first server for stability;
based upon the testing, deploying modifications to a second processor of a second server in the data center using the lowered voltage and the lowered frequency limit; and
maintaining a higher effective frequency on a third processor of a third server in the data center in comparison to the first processor based on a workload of the data center.
