3-22 Chapter 3: BIOS setup
• The value [2.2V] of the NB Voltage item is supported only if the OV_NB
jumper is enabled, otherwise the maximum voltage supported is [1.9V]. See
2. CPU / Northbridge overvoltage setting on page 2-24 for details.
• Setting the CPU PLL Voltage, FSB Termination Voltage, DRAM Voltage
and NB Voltage items to a high level may damage the chipset, memory
module and CPU permanently. Proceed with caution.
• Some values of the CPU PLL Voltage, FSB Termination Voltage, DRAM
Voltage and NB Voltage items are labeled in different color, indicating the
risk levels of high voltage settings. Refer to the table below for details.
• The system may need better cooling system to work stably under high
voltage settings.
Blue Yellow Purple Red
CPU PLL Voltage 1.50V~1.78V 1.80V~2.00V 2.02V~2.20V 2.22V~2.78V
FSB Termination Voltage 1.20V~1.38V 1.40V~1.90V N/A N/A
DRAM Voltage 1.80V~1.98V 2.00V~2.20V 2.22V~2.40V 2.42V~3.08V
NB Voltage 1.10V~1.26V 1.28V~1.40V 1.42V~1.58V 1.60V~2.2V
3.4.19 NB GTL Voltage Reference [Auto]
Allows you to set the Northbridge GTL voltage reference. Different ratio might
enhance CPU overclocking ability. The values range from 0.370x to 0.760x with a
0.005x interval.
3.4.20 SB Voltage [Auto]
Allows you to set the South Bridge voltage. The values range from 1.10V to 1.40V
with a 0.10V interval.
3.4.21 PCIE SATA Voltage [Auto]
Allows you to set the PCI Express SATA voltage. The values range from 1.50V to
1.80V with a 0.10V interval.
3.4.22 Load-Line Calibration [Auto]
Allows you to select the CPU Load-Line mode. Set to [Disabled] to follow Intel
specifications, or to [Enabled] to improve CPU VDroop directly.
Configuration options: [Auto] [Disabled] [Enabled]
3.4.23 CPU Spread Spectrum [Auto]
Set to [Disabled] to enhance FSB overclocking ability or [Auto] for EMI control.
Configuration options: [Auto] [Disabled]
