4-9
2-Core Ratio Limit (Available when "Turbo Mode" is set to Enabled)
This 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 the value. Enter 0 to use the manufacture default setting.
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. 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
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.
