3-20 Chapter 3: BIOS setup
3.4.12 CPU Voltage [Auto]
Allows you to set the CPU VCore voltage. The values range from 0.85000V to
2.10000V* with a 0.00625V interval.
• Refer to the CPU documentation before setting the CPU Vcore voltage.
Setting a high VCore voltage may damage the CPU permanently, and
setting a low VCore voltage may make the system unstable.
• The value [2.10000V] of the CPU Voltage item is supported only if the
OV_CPU jumper is enabled, otherwise the maximum voltage supported is
[1.70000V]. See 2. CPU / Northbridge overvoltage setting on page 2-19
for details.
3.4.13 CPU GTL Voltage Reference(0/2) [Auto]
Allows you to set the CPU GTL voltage reference. The values range from 0.370x
to 0.760x with a 0.005x interval. Different ratio might enhance CPU overclocking
ability.
3.4.14 CPU GTL Voltage Reference(1/3) [Auto]
Allows you to set the CPU GTL voltage reference. The values range from 0.410x
to 0.800x with a 0.005x interval. Different ratio might enhance CPU overclocking
ability.
3.4.15 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.
3.4.16 FSB Termination Voltage [Auto]
Allows you to set the front side bus termination voltage. The values range from
1.20V* to 1.90V with a 0.02V interval.
The minimum value of this item becomes 1.10V when a 45nm CPU is installed.
3.4.17 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.80V to 3.08V with a
0.02V interval.
3.4.18 NB Voltage [Auto]
Allows you to set the North Bridge voltage. The values range from 1.10V to 2.2V*
with a 0.02V interval.
