1. 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.

Tip: When should I Clear CMOS?

1. Boot fails because of overclocking…

2. Forget password…

3. Troubleshooting…

2. JP28 Keyboard/Mouse Wakeup Jumpers

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.

5. Setting CPU Voltage & Frequency

This motherboard comes with a 20-pin and 4-pin ATX power connector as shown below.
Make sure you plug in the right direction. We strongly recommend you to insert the 4-pin
connector before connecting the 20-pin connector.

4. Connecting Front Panel Cable

Attach the power LED, speaker, and reset switch connectors to the corresponding pins. If
you enable “Suspend Mode” item in BIOS Setup, the ACPI & Power LED will keep flashing
while the system is in suspend mode.
Locate the power switch cable from your ATX housing. It is 2-pin female connector from the
housing front panel. Plug this connector to the soft-power switch connector marked SPWR.

Full-range Adjustable CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 0.8375V to 1.6000V. It is not necessary to set CPU Core
Voltage.

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency through the
BIOS setup, and no jumpers or switches are needed.

BIOS Setup > Frequency / Voltage Control > CPU Bus Frequency

Core Frequency = CPU FSB Clock * CPU Ratio

CPU Ratio 8x, 10x… 24x, 25x, 26x, 27x, 28x

CPU FSB
(Adjustment manually)

FSB = 100MHz-255MHz by 1MHz Stepping
