PCI Standby Power LED
This LED will turn red when the
system is in the power-on, Soft-Off
or Suspend mode. It serves as a
reminder that you must power-off
the system then turn off the
power supply’s switch or unplug
the power cord prior to installing
any add-in cards.
The frequency ratio of some
processors shown in the table may
have been locked by the
manufacturer. If you are using this
kind of processor, setting an
extended ratio for the processor
will have no effect. The system will
instead use its factory default ratio.
The frequency ratio of processors
greater than 8x has been locked by the manufacturer and will no longer have the flexibility of using
extended ratios. Therefore, the system will use the processor’s factory default ratio.
The voltage regulator will automatically be set according to the voltage of the processor.
