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 eficient, resulting in further gains. The op-
tions are HW_ALL, SW_ALL and SW-ANY.
CPU C3 Report, CPU C6 Report
This BIOS feature enables or disables C3 or C4 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.
Turbo Boost Technology
Turbo Mode
This feature allows processor cores to run faster than marked frequency in
specic 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.

Warning: Take Caution when changing the Advanced settings. An incorrect
value, a very high DRAM frequency or incorrect DRAM timing may cause
system to become unstable. When this occurs, revert to the default setting.
The items included in the Advanced Settings submenu are listed below.
