1-Core Ratio Limit (Available when "Turbo Mode" is set to Enabled)
This feature increases (multiplies) 1 clock speed in the CPU core in relation to
the bus speed when one CPU core is active. Press "+" or "-" on your keyboard
to change this value. Enter 0 to use the manufacture default setting.
2-Core Ratio Limit (Available when "Turbo Mode" is set to Enabled)
This feature increases (multiplies) 2 clock speeds in the CPU core in relation to
the bus speed when two CPU cores are active. Press "+" or "-" on your keyboard
to change this value. Enter 0 to use the manufacture default setting.
Energy Performance
Use this feature to select an appropriate fan setting to achieve the maximum system
performance (with maximum cooling) or to achieve maximum energy efficiency (with
maximum power saving). The fan speeds are controlled by the firmware manage-
ment via IPMI 2.0. The options are Performance, Balanced Performance, Balanced
Energy, and Energy Efficient.
VR Current Value
Use this feature to set the limit on the current voltage regulator. Press "+" or "-" on
your keyboard to change this value. Enter 0 to use the manufacture default setting.
CPU C-States
C-States architecture, a processor power management platform developed by
Intel, can further reduce power consumption from the basic C1 (Halt State) state
that blocks clock cycles to the CPU. Select Enabled for CPU C-Sates support. The
options are Enabled and Disabled. If this feature is set to Enabled, the following
items will display:
Enhanced C1 State (Available when "CPU C-States" is set to Enabled)
Select Enabled to enable Enhanced C1 Power State to boost system perfor-
mance. The options are Enabled and Disabled.
CPU C3 Report (Available when "CPU C-States" is set to Enabled)
Select Enabled to allow the BIOS to report the CPU C3 State (ACPI C2) to the
operating system. During the CPU C3 State, the CPU clock generator is turned
off. The options are Enabled and Disabled.
CPU C6 Report (Available when "CPU C-States" is set to Enabled)
Select Enabled to allow the BIOS to report the CPU C6 State (ACPI C3) to the
operating system. During the CPU C6 State, the power to all caches is turned
off. The options are Enabled and Disabled.
