1.9 Jumpers
This section describes and illustrates the jumpers on the motherboard.
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 2.5.1 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 +1.65V 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).
