IMPORTANT:
• Do figure out the correct processor type by processor’s OPN (Ordering
Part Numbers). Correct CPU external frequency is key to ensure reliability
of your system.
• Incorrect CPU external frequency or overclocking might cause unstable
performance, so we strongly recommend to leave “SW1” at default setting
or legal operation.
