Description
Options are OS Control, Custom, and
Maximum Performance. The BIOS pre-
configures the power settings on this screen as
follows:
• OS Control sets the processor power to OS
DBPM, the fan power to Minimum Power,
and the memory power to Maximum
Performance. In this setting, all processor
performance information is passed from the
system BIOS to the operating system for
control. The operating system sets the
processor performance based on processor
utilization.
• Maximum Performance sets all fields to
Maximum Performance.
• If you select Custom, you can configure each
option independently.
