This page contains a summary of the important notes that must be
given special attention to prior to using the system board.
AGP Pro Slot
The system board is equipped with a universal AGP Pro slot that
supports 2x/4x AGP or AGP Pro add-in card. If you are using 2x/4x
AGP add-in card, make sure you install the card between the 20-pin
and 28-pin bays of the slot. Installing it incorrectly may damage the
card or the system board. AGP Pro add-in cards, on the other hand,
will fit into the AGP Pro slot in only one orientation thus preventing
you from installing the add-in card incorrectly.
Processor
• The frequency ratio of some processors 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.
• Selecting an external bus clock other than 66MHz, 100MHz or
133MHz may result to the processor’s or system’s instability and
are not guaranteed to provide better system performance.
System Memory
The system board supports both VCM and PC SDRAM DIMMs. If
you are using more than one DIMM, make sure you insert the same
type of DIMMs into the DIMM sockets. Using different types (VCM
or PC SDRAM) of DIMMs may cause problems.
5VSB Power
• If you are using the (1) Wake-On-LAN and/or (2) Wake-On-
Ring (internal modem) functions, the 5VSB power source of your
power supply must support
≥
720mA.
• If you are using the Suspend to RAM function, the 5VSB power
source of your power supply must support
≥
1A.
Drivers
Make sure to reboot the system after each driver installation.
Problems will occur if you reboot only after installing all the drivers.
