Switch and jumpers

1. CPU external frequency selection (DSW Switches 1-5) The motherboard frequency is adjusted through the DIP switches. The white block represents the switch position. The illustration below shows the ON and OFF positions of the switches.

ON OFF

A7V400-MX DIP Switches
The option to set the CPU core bus frequency multiple is available only on unlocked CPUs. If you are using a locked CPU, setting the switches does not produce any effect.
The DSW switch tells the clock generator what frequency to send the CPU. This allows the selection of the CPUs external frequency (or bus clock). The bus clock multiplied by the frequency multiple equals the CPUs internal frequency (the advertised CPU speed).
The default CPU external frequency is 100MHz. If your CPU supports 133/166MHz external frequency, adjust the DSW settings before installing the motherboard to the chassis.

Set the CPU frequency only to the recommended settings. Frequencies other than the recommended CPU bus frequencies are not guaranteed to be stable.
2. USB device wake-up (3-pin USBPWR34, USBPWR56, USBPWR78) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). Both jumpers are set to pins 1-2 (+5V) by default because not all computers have the appropriate power supply to support this feature. The USBPWR34 jumper is for the rear USB ports. USBPWR56 and USBPWR78 are for the internal USB headers that you can connect to additional front/rear USB ports.
The USB device wake-up feature requires a power supply that can provide 500mA on the +5VSB lead for each USB port. Otherwise, the system does not power up. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode. USBPWR34
