3-16 Chapter 3: BIOS setup
Chapter 3
3.5.13 CPU Voltage [Auto]
Allows you to set the CPU VCore voltage. Use the <+> and <-> keys or the numeric keypad
to enter the desired value. 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 overvoltage setting on page 2-23 for details.
3.5.14 CPU GTL Reference [Auto]
Allows you to set the CPU GTL reference voltage. Different ratio might enhance CPU
overclocking ability. Conguration options: [Auto] [0.65x] [0.63x] [0.61x]
The following six (6) items are adjusted by typing the desired values using the numeric
keypad and press the <Enter> key. You can also use the <+> and <-> keys to adjust the
value. To restore the default setting, type [auto] using the keyboard and press the <Enter>
key.
3.5.15 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.
3.5.16 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.
3.5.17 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.80V to 3.08V with a 0.02V
interval.
3.5.18 NB Voltage [Auto]
Allows you to set the North Bridge voltage. The values range from 1.10V to 1.90V with a
0.02V interval.
• 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 Voltage
,
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 on the next page for details.
• The system may need better cooling system to work stably under high voltage
settings.
