Before you change the jumper settings for extra-high overvoltage ability,
use the BIOS items introduced in 4.4 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
4.4 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 1.91V
Pins 1-2 (OV Enabled) up to 2.10V up to 2.21V
