CPU Host Frequency Setting (JP8)
The default CPU host frequency setting is 66MHz. It is defined according to
Intel Celeron CPU specification. We strongly advise novice users not to
modify the original setting of the CPU host frequency, for setting an incor-
rect value may damage your CPU.
For experienced users, the AV11 mainboard provides an alternative Hard-
Configure function to adjust your CPU host frequency manually.
Note:
Before you adjust your CPU host frequency by jumper, you need to
set CPU Host/PCI Clock to
default
in frequency/voltage control of
BIOS setup program.
Insert mini-jumper caps properly on JP8 to reach desired CPU
Host Frequency, as shown in the following table.

Note:
75, 83 MHz are over-clock
usage for 66MHz base processor,
and 112~150MHz are over-clock
usage for 100MHz base processor.
However, over-clocking is not a
recommended practice.
