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.

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 1.6V. 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
CPU FSB
(Adjustment manually)
FSB = 100MHz-400MHz by 1MHz Stepping

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
.
Note: Intel 865G
chipsets don’t support
Willamette or Celeron
processors.
Northwood processor
can detect the clock
ratio automatically;
you may not be able
to adjust the clock
ratio in BIOS
manually.
Warning: Intel 865G
chipsets support
maximum 800MHz
(200MHz*4) system
bus and 66MHz AGP
clock; higher clock
setting may cause
serious system
damage.
