4-22 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.
