Jp14 Clear Cmos - AOpen AX4SG MAX II Easy Installation Manual

Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on. However, if users are willing to do overclocking,
we also provide a range from 1.10V to 1.85V in the BIOS. Sometimes increasing
the original core voltage a little bit will lead the CPU overclock more properly.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through
1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB
clock x CPU Ratio. However, all CPU now selling in the market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but only change CPU
FSB clock to achieve overclocking.
(Users do the overclocking at their own risk!!)
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
CPU Ratio 8x, 10x... 24x, 25x, 26x, 27x, 28x
CPU FSB FSB = 100MHz-400MHz

JP14 Clear CMOS

You can clear CMOS to restore system default
setting. To clear the CMOS, follow the procedure
below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pin
1 & pin 2.
5. Connect ATX power cable back to connector
PWR2.

JP28 Keyboard/Mouse Wakeup Jumper
This motherboard provides keyboard / mouse wake-up function. You can use JP28
to enable or disable this function, which could resume your system from suspend
mode with keyboard or mouse. The factory default setting is "Disable" (1-2), and
you may enable this function by setting the jumper to 2-3.
Tip: When should I Clear CMOS?
1. Boot fails because of overclocking...
2. Forget password...
3. Troubleshooting...
