ASUS A7V-E User’s Manual 23
3. HARDWARE SETUP
3.6 Central Processing Unit (CPU)
The motherboard provides a Socket 462 or Socket A for CPU installation. The CPU
that came with the motherboard should have a fan and heatsink attached to it to
prevent overheating. If this is not the case, then purchase and install a set before you
turn on your system.
WARNING! Make sure that the heatsink is mounted tightly against the processor.
Make sure also that there is sufficient air circulation across the processor’s heatsink
by regularly checking that your CPU fan is working. Without sufficient circulation,
the processor could overheat and damage both the processor and the motherboard.
You may install an auxiliary fan, if necessary. A CPU thermal sensor is integrated on
the motherboard, located near the center of the CPU heat source, just below the CPU
socket, to help in monitoring the CPU temperature.
To install a CPU, first turn off your system and remove its cover. Locate the Socket
462 and open it by first pulling the lever sideways away from the socket, then up-
wards. The socket lever must be fully opened (90 to 100 degrees) when installing or
removing the CPU. Insert the CPU with the correct orientation. The notched corner
should be oriented toward the blank space on the socket nearest the lever. The CPU
has a corner pin for two of the four corners, and will only fit in the orientation as
shown. Ensure that the CPU is exactly parallel to the socket base so the pins make
good contact and are not bent. Take care not to exert too much force, but press the
CPU down gently into the slot. Once completely inserted, close the socket lever
while holding down the CPU. Attach the CPU heatsink so that it covers the entire
face of the CPU and then connect the CPU fan.
NOTE: If necessary, do not forget to set the correct Bus Frequency and Multiple for
your processor or else boot-up may not be possible. Frequency multiple settings are
available only on unlocked processors.
CAUTION! Be careful not to scrape the motherboard surface when mounting a
clamp-style processor fan or else damage may occur. When mounting a heatsink
onto your CPU, make sure that the CPU capacitors do not touch the heatsink;
otherwise, your CPU will be damaged! See your heatsink/CPU documentation
for details.
