Manual for Advance 6A/Advance 6B
If CPU FSB is set as 66MHz, the system only run at 66MHz front side bus even if a processor
with 100MHz or higher. If CPU FSB is set as 100MHz, the system can run at 100MHz front side
bus even if a processor with 66MHz FSB is installed. Setting up to 133MHz FSB is also
supported. However, whether or not your system can be overclocked depends on your
processor’s capability. For bus ratio unlocked processor, this overclocking feature can be
implemented with CPU bus ratio selection Jumpers JX1~JX4. We do not guarantee the
overclocking system to be stable.
CPU bus ratio selection (JX1, JX2,JX3, JX4)
The Host Bus speed by the CPU bus ratio equals the CPU’s internal frequency (CPU speed)
If Host Bus speed = 100MHz, CPU bus ratio =4
then CPU speed= 100MHz x 4= 400MHz
please setup CPU bus ratio according to the following table.

Note: The Most of Socket 370 processors have locked bus ratio. In this case,
it’s not necessary to setup the bus ratio by Jumper setting. So
only unlocked Socket 370 processpors can adjust specified bus ratio
through hardware jumper setting .
Warning:
Dot not set CPU frequency higher than its working frequency. If you do, we will not
be responsible for any damages caused.
