This feature enables the CPU to run at a higher than normal rate. When all CPU cores are not necessary for the workload, inactive cores are turned off and power is diverted to the active cores to increase their performance.

Turbo Boost is enabled and disabled in workstation BIOS. For instructions on setting BIOS features, see The Computer Setup (F10) Utility on page 29.
