BIOS Controls EPB)
Use this feature to confi gure the optimal operation setting for your machine by achieving
the desired system performance level and energy saving (effi ciency) level at the same time.
Select Maximum Performance to maximize system performance to its highest potential;
however, this may consume maximal amount of power as energy is needed to fuel the
processor frequency. (In other words, system performance is gained at the cost of system
power effi ciency, depending on the workload.) Select Maximum Power Effi ciency to minimize
power use; however, system performance will be greatly impacted as the result of power
saving. The options are Maximum Performance, Performance, Balanced Performance,
Balanced Power, Power, and Max (Maximum) Power Effi cient.
CPU P State Control (Available when "Power Technology" is set to
Custom)
SpeedStep (P-States)
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust

dissipation. Please refer to Intel’s website for detailed information. The options are Disable
and Enable.
