ASUS P5QC 2-23

4. CPU / Northbridge overvoltage setting (3-pin OV_CPU; 3-pin OV_NB)

These jumpers allow you to enable or disable the advanced CPU and

Northbridge overvoltage settings in BIOS. Read the following information

before you change the jumper settings. Set to pins 1-2 to activate the

advanced CPU / Northbridge overvoltage feature.

• Before you change the jumper settings for extra-high overvoltage ability,

use the BIOS items introduced in

3.4 Ai Tweaker

rst to adjust the desired

CPU and Northbridge performance. Make sure your system function well

under the highest BIOS voltage settings before you change the setting of

these two jumpers.

• Refer to

3.4 Ai Tweaker

for more information about CPU and Northbridge

overvoltage settings.

• DO NOT set the OV_CPU jumper to pins 1-2 when you install a new CPU

and have not booted for the rst 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.

OV_CPU OV_NB

Pins 2-3 (Default) up to 1.70V up to 1.76V

Pins 1-2 (OV Enabled) up to 2.10V up to 2.20V
