2.2 System Memory
Warning:
• To ensure proper boot up and operation of your system, you must
power-off the system then turn off the power supply’s switch or
unplug the AC power cord prior to altering the setting of a jumper
or replacing the CPU.
• Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD
workstation only. If such a station is not available, you can provide
some ESD protection by wearing an antistatic wrist strap and
attaching it to a metal part of the system chassis. If a wrist strap
is unavailable, establish and maintain contact with the system
chassis throughout any procedures requiring ESD protection.
The system board is equipped with three 184-pin DDR SDRAM
DIMM (Dual In-line Memory Module) sockets that support 2.5V
DDR SDRAM DIMM. Double Data Rate SDRAM (DDR SDRAM)
is a type of SDRAM that doubles the data rate through reading
and writing at both the rising and falling edge of each clock. This
effectively doubles the speed of operation therefore providing
two times faster data transfer.

Hardware Installation
Refer to chapter 1 (System Memory section) for detailed specification of the memory supported by the system board.
The three DDR DIMM sockets on the system board are divided
into 2 channels:
1st channel - DDR 1 and DDR 2
2nd channel - DDR 3
The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits (8B) from the
memory channels.
Dual Channel (DC)
Dual channel provides better system performance because it
doubles the data transfer rate.
DIMMs are on the same channel.
DIMMs in a channel can be identical or
completely different. However, we highly
recommend using identical DIMMs.
Not all slots need to be populated.
DIMMs of the same memory configuration are on different channels.

2.3.3 Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink.
Without sufficient air circulation across the CPU and heat sink,
the CPU will overheat damaging both the CPU and system board.
1. Before you install the fan / heat sink, you must apply a thermal paste onto the top of the CPU. The thermal paste, which
is usually supplied together with the CPU, looks somewhat
similar to the one shown below. Do not spread the paste all
over the surface. When you later place the heat sink on top
of the CPU, the compound will disperse evenly.
