Power Technology
This feature determines what power-saving scheme the motherboard uses. The
options are Disabled, Energy Effi cient and Custom. If Custom is selected, the
following options become available:
EIST
EIST (Enhanced Intel SpeedStep Technology) allows the system to automati-
cally adjust processor voltage and core frequency in an effort to reduce
power consumption and heat dissipation. Please refer to Intel's web site
for detailed information. The options are Disabled and Enabled.
P-STATE Coordination
This feature selects the type of coordination for the P-State of the processor.
P-State is a processor operational state that reduces the processor's voltage
and frequency. This makes the processor more energy effi icient, resulting in
further gains. The options are HW_ALL, SW_ALL and SW-ANY.
CPU C3 Report, CPU C6, CPU C7 Report
This BIOS feature enables or disables C3 (ACPI C2), C6 (ACPI C3), C7
(ACPI C3) reporting to the operating system. The options are Disabled and
Enabled.
Package C State Limit
If set to Auto, the AMI BIOS will automatically set the limit on the C-State package
register. The options are C0, C1, C6, C7 and No Limit.
Intel® Turbo Boost Technology (Available if Intel® EIST technology is
Enabled)
Turbo Mode
This feature allows processor cores to run faster than marked frequency in
specifi c conditions. The options are Disabled and Enabled.
Long duration power limit - this is the processor power consumption limit
(in Watts) during a long duration time window.
Long duration maintained - this is the time in milliseconds where the Long
Duration Power Limit is maintained.
Short duration power limit - During Turbo Mode, the system may exceed
the processor's default power setting and exceed the Short Duration Power
limit. By increasing this value, the processor can provide better performance
for a short duration.
