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.

2. The method of claim 1 , wherein the voltage of the first processor is lowered to a guardband level.

3. The method of claim 2 , wherein the voltage of the first processor is lowered to level that prevents an overcurrent in the first processor.

4. The method of claim 2 , wherein the voltage of the first processor is lowered to a level that prevents an overfrequency in the first processor.

5. The method of claim 2 , further comprising lowering the voltage of the first processor below the guardband level after determining the stability point.

6. The method of claim 1 , wherein the voltage and frequency modifications are deployed to plurality of servers in the data center.

7. The method of claim 1 , wherein a first core of the first processor is disabled.

8. The method of claim 1 , wherein the workload is determined based on a number of heavily threaded jobs that are executed.

9. The method of claim 1 , wherein the frequency limit is determined based on a maximum stable temperature at which the first processor can operate.

10. The method of claim 1 , wherein the first processor and the second processor are from a same bin of produced parts.
