Chapter 4: BIOS setup
4.4.14 CPU GTL Voltage Reference (0/2) [Auto]
Allows you to set the CPU GTL voltage reference. Different ratio might enhance CPU
overclocking ability. The values range from 0.370x to 0.760x with a 0.005x interval.
4.4.15 CPU GTL Voltage Reference (1/3) [Auto]
Allows you to set the CPU GTL voltage reference. Different ratio might enhance CPU
overclocking ability. The values range from 0.410x to 0.800x with a 0.005x interval.
4.4.16 CPU PLL Voltage [Auto]
Allows you to set the CPU PLL voltage. The values range from 1.50V to 2.78V with
a 0.02V interval.
4.4.17 FSB Termination Voltage [Auto]
Allows you to set the front side bus termination voltage. The values range from
1.20V to 1.50V with a 0.02V interval.
4.4.18 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.50V to 2.78V with a
0.02V interval.
4.4.19 NB Voltage [Auto]
Allows you to set the North Bridge voltage. The values range from 1.25V to 2.21V*
with a 0.02V interval.
• The value [2.21V] of the NB Voltage item is supported only if the OV_NB
jumper is enalbed, otherwise the maximum voltage suppoted is [1.91V].
See 2. CPU / Northbridge overvoltage setting on page 2-23 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.
