HARDWARE SETUP
2-1 CPU INSTALLATION
WARNING:
• Make sure that +5V DVC and +3.3 DVC capabilities of your power supply
are suitable for the processor.
• Any attempt to operate the AMD Athlon or Duron processor without a suitable cooling Fan will result in permanent damage to the processor and
potentially other component within the system.
1. Pull the lever sideways away from the socket, and then raise the lever up
to a 90-degree angle.
SOCKET 462
2. Take note of the red circle as below picture. While inserting the CPU into
the socket, you can find out there is a definite pin orientation for CPU and
socket.

2-2 MEMORY INSTALLATION
WARNING!!!
• Make sure that you unplug your power supply when adding or removing memory modules or other system components. Failure to do so
may cause severe damage to both your mainboard and expansion
cards.
• Be careful when inserting or removing DIMM, forcing a DIMM in or out
of a socket can be damaged the memory module or the socket. Some of
DIMMs contain EDO or FTP DRAM. These DIMM types are incompliant
with the motherboard, the M/B only supports 3.3V true SDRAM DIMMs
Installing DIMM
• Make sure you have the correct memory module type for your
motherboard.
• Insert the module(s) as shown, DIMMs have 168-pins and two notches
that will match with the onboard DIMM socket, memory modules are
installed by inserting them straight into the slot until they “click” into
place. They only fit in one direction so do not force them into place.

Removing DIMM
• Press the holding clips on both sides of socket out ward to release
the DIMM out of the socket.

CAUTION!!
The AGP Pro slot is shipped with a warning label over the 20-pin bay.Do
not remove this label and the safety tab underneath it if you will
be using an AGP card without a retention notch.Removing may
cause the card to shift and may cause damage to your card ,
slot , and motherboard. Remove ONLY when you will be using
an AGP Pro card.

2-4 HDD / FDD INSTALLATION
• To install HDD (Hard Disk Drive), you may connect the cable’s blue
connector to the motherboard’s primary (IDE1) or secondary IDE
connector, and then connect the gray connector to your slave device
and the black connector to your master device.If you install two hard
disks , you must configure the second drive to Slave mode by setting
its jumper accordingly.Please refer to your hard disk documentation
for the jumper settings.
• To install FDD (Floppy Disk Drive), you may connect the single end to
the board , and connect two plugs on the other end to the floppy drives.

IMPORTANT:
• You may figure out the correct processor type by processor’s OPN
(Ordering Part Numbers), select correct CPU external frequency is
key to ensure reliable operation.
• Incorrect CPU external frequency or overclocking are not guaranteed
to be stable, we strongly recommended to leave “SW1” at default
setting or legal operation.
20
75KAV/75KAV-X
2-7 BUS RATIO SELECT
• The AMD Athlon and Duron processor provides four Frequency ID
signals (FID) to the system controller to indicate the SYSTCLK
multiplier at which the processor core operates, This mechanism is
automatic. The board maker does not guarantee “Bus Ratio” can be selected
if the processor does not support it.
• When LED “SSF1” light is on, meaning that Bus Ratio Select Function is
enabled.

Those connectors support processor/system cooling fan with +12V.
Those support three pin head connector. When connecting the wire
to FAN connectors, user should give attention that the red wire is
the positive and should be connected to the +12V, the black wire is
Ground and should be connected to GND. If your motherboard has
Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send
out 2 pulses. System Hardware Monitor will count and report the
fan rotation speed.

NOTE 1: Always consult vendor for proper CPU cooling fan.
