✏ Multiplier Factor:
You can choose the following multiplier factors:
➤ x 2 ➤ x 2.5 ➤ x 3 ➤ x 3.5 ➤ x 4 ➤ x 4.5 ➤ x 5 ➤ x 5.5 ➤ x 6
➤ x 6.5 ➤ x 7 ➤ x 7.5 ➤ x 8

✏ SEL100/66# Signal
Two options are available: Default and Low. The default setting is “Default”.

✏ PCI Clock/CPU FSB Clock
Three options are available: 1/2, 1/3 and 1/4. This item lets you set the PCI clock. It
correlates with the CPU FSB clock you set. For example, if you set the CPU FSB
clock to 100MHz and choose 1/3 here, the PCI clock will be 33.3 MHz.

✏ AGP Clock/CPU FSB Clock
Two options are available: 1/1 and 2/3. This item lets you set the AGP clock. It
correlates with the CPU FSB clock you set. The default setting is “1/1”. In this case,
the AGP clock will equal to the CPU FSB clock. If you choose “2/3”, the AGP clock
will be the CPU FSB clock divided by 3 and times 2. Generally, if you set the CPU
FSB clock to 66MHz, you ought to select “1/1”. If you set the CPU FSB clock to
100Mhz or higher, you ought to select “2/3”.

✏ AGP Transfer Mode
This function allows the user to determine the capability of the AGP device.
Selecting “Default” gives optimized performance. The video driver will decide the
data transfer mode automatically. If the CPU FSB clock exceeds 125MHz, setting
AGP Transfer Mode to “Normal” will result in a more stable system.

✏ CPU Core Voltage
This item lets you select the CPU core voltage manually. You can change values in
the “
CPU Core Voltage ” option lists by using the arrow up and down keys.
!!! Warning !!!
You must check the CPU document to make sure your CPU core voltage before
you want to adjust this item. Incorrect CPU core voltage settings in certain
circumstances may cause CPU damage.

I/O Voltage
This item lets you select the voltage supplied to the DRAM, chipset and AGP. You
can change values in the “
I/O Voltage ” option lists by using the arrow up and down
keys.
