2. CPU overvoltage setting (3-pin OV_CPU) This jumper allows you to enable or disable the advanced CPU overvoltage setting in BIOS. Read the following information before you change the jumper setting. Set to pins 1-2 to activate the advanced CPU overvoltage feature. Pins 2-3 (Default) Pins 1-2 (OV Enabled) OV_CPU 0.80V - 1.70V up to 1.90V • Before you change the jumper setting for extra-high overvoltage ability, use the BIOS items introduced in 2.4 Ai Tweaker menu first to adjust the desired CPU performance. Ensure that your system functions well under the highest BIOS voltage setting before you change the setting of this jumper. • Refer to 2.4 Ai Tweaker menu for more information about the CPU overvoltage setting. • DO NOT set the OV_CPU jumper to pins 1-2 when you install a new CPU and have not booted for the first time. Doing so may cause the system to halt. For system failure due to the wrong setting of the OV_CPU jumper, shut down the computer and move the cap back to pins 2-3. • The system may need a better cooling system (for example, a water-cooling system) to work stably under high voltage settings. 1-18 ASUS M4N72-E

CPU overvoltage setting (3-pin OV_CPU)
This jumper allows you to enable or disable the advanced CPU overvoltage setting in
BIOS. Read the following information before you change the jumper setting. Set to pins
1-2 to activate the advanced CPU overvoltage feature.
•
Before you change the jumper setting for extra-high overvoltage ability, use
the BIOS items introduced in
2.4 Ai Tweaker menu
first to adjust the desired
CPU performance. Ensure that your system functions well under the highest
BIOS voltage setting before you change the setting of this jumper.
•
Refer to
2.4 Ai Tweaker menu
for more information about the CPU overvoltage
setting.
•
DO NOT set the OV_CPU jumper to pins 1-2 when you install a new CPU and
have not booted for the first time. Doing so may cause the system to halt. For
system failure due to the wrong setting of the OV_CPU jumper, shut down the
computer and move the cap back to pins 2-3.
•
The system may need a better cooling system (for example, a water-cooling
system) to work stably under high voltage settings.
