4-9

3-Core Ratio Limit (Available when "Turbo Mode" is set to Enabled)

This increases (multiplies) 3 clock speeds in the CPU core in relation to the bus

speed when three CPU cores are active. Press "+" or "-" on your keyboard to

change the value. Enter 0 to use the manufacture default setting.

4-Core Ratio Limit (Available when "Turbo Mode" is set to Enabled)

This increases (multiplies) 4 clock speeds in the CPU core in relation to the bus

speed when four CPU cores are active. Press "+" or "-" on your keyboard to

change the 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 maximum energy efciency (with maximum

power saving). The fan speeds are controlled by the rmware management via IPMI

2.0. The options are Performance, Balanced Performance, Balanced Energy, and

Energy Efcient.

VR Current Value

Use this feature to set the limit on the current voltage regulator (VR). Press "+" or

"-" on your keyboard to change this value. Enter 0 to use the manufacture default

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 C1E 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
