11G Servers will be the most energy smart
servers that Dell will ship. In addition to P,C
and T states, BIOS will expose the Power
Profiles to the OS. Each Power profile will have
a specific settings and it will fine tune
processor, MCH, IOH and South Bridge. For

Maximum Performance
DBPM Disabled ( BIOS will set P-State to MAX)
Memory frequency = Maximum Performance
Fan algorithm = Maximum Performance
OS Control
Enable OS DBPM Control (BIOS will expose
all possible P states to OS)
Memory frequency = Maximum Performance
Fan algorithm = Minimum Power
Active Power Controller
Enable DellSystem DBPM (BIOS will not make all P states
available to OS)
Memory frequency = Maximum Performance
