- 55 - BIOS Setup
******** Clock Driving & Skew Control ********
CPU/PCIEX Clock Driving Control
Allows you to adjust the amplitude of the CPU, North Bridge and PCI Express clock.
Options are: 700mV, 800mV (default), 900mV, 1000mV.
CPU Clock Skew Control
Allows you to set the CPU clock prior to the North Bridge clock.
Options are: Normal (default), 50ps~750ps.
(G)MCH Clock Skew Control
Allows you to set the North Bridge clock prior to the CPU clock.
Options are: Normal (default), 50ps~750ps.
******** System Voltage Optimized ********
System Voltage Control
Determines whether to manually set the system voltages. Auto lets BIOS automatically set the
system voltages as required. Manual allows all voltage control items below to be configurable.
(Default: Manual)
DDR2 OverVoltage Control
Allows you to set memory voltage.
Normal Supplies the memory voltage as required. (Default)
+0.05V ~ +1.55V Increases memory voltage by 0.05V to 1.55V at 0.05V increment.
Note: Increasing memory voltage may result in damage to the memory.
PCI-E OverVoltage Control
Allows you to to set PCIe voltage.
Normal Supplies the PCIe bus voltage as required. (Default)
+0.05V ~ +0.75V Increases PCIe bus voltage by 0.05V to 0.75V at 0.05V increment.
FSB OverVoltage Control
Allows you to set the Front Side Bus voltage.
Normal Supplies the FSB voltage as required. (Default)
+0.05V ~ +0.35V Increases FSB voltage by 0.05V to 0.35V at 0.05V increment.
(G)MCH OverVoltage Control
Allows you to set the North Bridge voltage.
Normal Supplies the North Bridge voltage as required. (Default)
+0.025V ~ +0.775V Increases North Bridge voltage by 0.025V to 0.775V at 0.025V increment.
Loadline Calibration
Enabled Lets the BIOS fine-tune the CPU Vcore voltage. (Default)
Disabled Disables this function.
CPU Voltage Control
Allows you to set the CPU voltage. Normal sets the CPU voltage as required. The adjustable
range is dependent on the CPU being installed. (Default: Normal)
Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the
CPU.
Normal CPU Vcore
Displays the normal operating voltage of your CPU.
