2.7 Jumpers
1. Keyboard power (3-pin KBPWR1)
This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) if you wish to wake up the
computer when you press a key on the keyboard (the default value is
[Disabled]). This feature requires an ATX power supply that can supply
at least 1A on the +5VSB lead, and a corresponding setting in the
BIOS (see section 4.5.1 Power Up Control).
2. V
CORE
over-voltage (3-pin OVER_VOLT1)
When enabled, this jumper allows CPU V
CORE
ranges of 1.7V to 2.05V.
When this jumper is disabled, V
CORE
setting has a range of +1.5V to
+1.85V. You may adjust the CPU V
CORE
through the BIOS Setup.
Setting to a very high core voltage may cause permanent damage to
the CPU. It is recommended that you keep the default setting
(Disable).
