Note: SOYO does not guarantee system stability if the user over clocks the system. Any malfunctions due to over-clocking are not covered by the warranty.

Step 5. Enable/Disable Power-On by Keyboard (JP1)

You may choose to enable the Power-On through Keyboard function by shorting pin 2-3 on jumper JP1; or short pin 1-2 to disable this function.

Important: When using the Power-On by Keyboard function, please make sure the ATX power supply is able to provide at least 720mA on the 5V Standby lead (5VSB) in order to meet the standard ATX specification.

Step 6. The synchronous / asynchronous clock mode between CPU

and memory interface setting

The FSB Frequency can also be set through DIP switch FJ1 or BIOS and it may therefore differ from the Frequency the CPU specifies. Doing so may however force your CPU to operate out of its specifications and therefore SOYO can not guarantee the proper functioning of your system.
