WARNING! Make sure that you unplug the power supply when adding or
removing memory modules or other system components. Failure to do so may
cause severe damage to both the motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).
Insert the module(s) into the DIMM sockets as shown. Because the number of pins
are different on either side of the breaks, the module only fits in one direction. SDRAM
DIMMs have different pin contacts on each side and have a higher pin density than
DRAM SIMMs.

The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,
check the notches on the DIMMs (see the figure below).

The notches on the DIMM shifts between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must tell your retailer the correct DIMM type before purchasing.

Note in the illustration that CPUs have marks (usually a notch or a gold mark on one
corner) to help you identify the proper orientation and enable you to correctly install
a CPU. It is important that you match the marked corner of the CPU with the
corresponding corner on the socket so as not to damage the CPU pins.
The CPU picture above is for reference only. Usually, when you buy a CPU, the
heatsink and fan are already attached to the CPU. If a heatsink and fan did not come
with the package, make sure you obtain one before installing the CPU.
WARNING! You must install the proper heatsink and fan to the CPU. Failure to
do so will cause the CPU to overheat and may damage both the CPU and the
motherboard. Install an auxillary fan, if necessary.

3.7 Expansion Cards
In the future, you may need to install expansion cards. The motherboard has five
PCI expansion slots to support these cards. Follow the steps in the next section
when installing expansion cards.
WARNING! Unplug the system power cord when adding or removing expansion
cards or other system components. Failure to do so may cause severe damage to
both the motherboard and expansion cards.
3.7.1 Installing an Expansion Card
1. Read the documentation that comes with the expansion card and make any
necessary hardware settings for the card before installing it.
2. Remove the chassis cover and the bracket plate on the slot you intend to use
(assuming that the motherboard is already installed in a chassis). Keep the screw
for later use.
3. Align the card connectors with the slot and press firmly until the card fits in
place.
4. Secure the card to the slot with the screw you removed earlier.
5. Replace the system cover.
6. Change the necessary BIOS settings, if any.
(see section 4.4.3 PCI Configuration to change the settings.)
7. Install the necessary software drivers for the expansion card.

3.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally , an IRQ must be exclusively
assigned to one use. In a standard design, there are 16 IRQs available but most of
them are already in use, leaving 6 IRQs free for expansion cards. If your motherboard
has PCI audio onboard, an additional IRQ will be used. If your motherboard also
has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.
IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Conflicts arise between
the two PCI groups that will make the system unstable or cards inoperable.
The following table lists the default IRQ assignments for standard PC devices. Use
this table when configuring your system and for resolving IRQ conflicts.
