2-3.4 Jumper Setting

Step 1. Set J6 &JP2 to configure CPU FSB Frequency

If the user wants to use the CPU at its standard FSB (Front Side Bus)

Frequency, J6 has to be closed. This will make sure the system will

provide the CPU with the FSB Frequency it was specified to run at. Make

sure that JP2 is open when using this setting.

If the user wants to run the CPU at another (higher) FSB frequency

however, J6 has to be open. In this case use JP2 to set the FSB frequency.

Note: The “Manual” mode setting facilitates FSB over-clocking. Doing so will however force your CPU to operate out of its specifications, and therefore SOYO can not guarantee the proper function of your system.
