Easy Installation Procedure
The following must be completed before powering on your new system:
3-1. CPU Installation
3-2. Jumper Settings
3-3. System Memory Configuration
3-4. Expansion Slots
3-5. Device Connectors
3-1 CPU Installation
<Figure 1>
Step 1
Carefully remove the plastic protection plate from the
socket.
Step 3
Before inserting the CPU, align the CPU according
to the key slots shown in the picture. Gently place
the CPU into the socket and make sure it is fully
seated.
<Figure 2>
Step 2
Open the socket by releasing
the actuation lever, and press
downwards at the tip shown by
the arrow.
Warning:
The pins inside the CPU socket are fragile and are
easily broken. Be careful not to touch them when
installing the CPU.
<Figure 3>

Installation
Page 3-4
Step 4
a) Put the CPU lid on the socket, and
close the socket by lowering and
locking the actuation lever.
b) Apply thermal compound to the top
of the CPU and into the four holes
around CPU area to install the cooler
as shown.
<Figure 6>
Step 5
Place the CPU cooler on top of the socket.
Press its clips down firmly until it is
completely seated in the hole.
Step 6
a) Rotate the clips 90 degrees to lock
the CPU cooler in place.
b) Plug the cooler fan power into the
mainboard’s CPU fan connector.
The installation is complete.
CAUTION:
• Installing with incorrect CPU cooler and heatsink assemblies may damage the CPU. Use
Intel’s thermal solution shown in the illustrations above: an active heatsink; an extruded
aluminum heatsink base; and a fan attached to the top of the fin array.
• Apply thermal compound or paste to the CPU to avoid CPU overheating and damage.
• In accordance with Intel guidelines specifications, do not install a CPU over 20 times to
avoid damaging the pins on the CPU socket.

JCMOS:
Settings:
1-2: Normal (Default)
2-3: Clear CMOS
Clear CMOS data Jumper
If the CMOS data becomes corrupted or
you forgot the supervisor or user
password, clear the CMOS data to
reconfigure the system back to the
default values stored in the ROM BIOS.
To CMOS Clear data, please follow the steps below.
1. Turn off the system.
2. Change the jumper from “1-2” to “2-3” position for
a few seconds.
3. Replace the jumper on to the “1-2” position.
4. Turn on the system and hold down the <Del> key
to enter BIOS setup.

3-3 System Memory Configuration
The mainboard accommodates four PC2700/PC3200 184-pin DIMMs (Dual In-line
Memory Modules):
• Supports up to 4.0GB of 333/400MHz DDR SDRAM.
• Supports dual channel memory interface.
• Supports non-ECC memory and non-Registered DIMMs only.
• Supports 256Mb/512Mb/1Gb DDR technologies in x8 and x16 devices only.
• SPD (Serial Presence Detect) scheme for DIMM detection support.
• Supports configurations defined in the JEDEC DDR DIMM specification only.
Memory configurations supported:
• The four DIMM sockets are divided into two Dual Channel pairs according to
the color <Figure 7>. Each dual channel pair has the same color, e.g. DIMM1
and DIMM3. <Figure 8> shows the logical memory layout. We recommend
you to use DIMM sockets of the same color to obtain the best memory
performance.
- Single Channel Flexibility:
Each channel is populated with different amount of memory.
- Dual Channel Advantage:
Both channel populated with same amount of memory.

Note: Using non-compliant memory with higher bus speeds (overclocking) may
severely compromise the integrity of the system.

DIMM Module Installation
Figure 9 displays the notch on the DDR DIMM memory module.
DIMMs have 184 pins and one notch that matches with the DDR DIMM socket.
DIMM modules are installed by placing the chip firmly into the socket and
pressing straight down as shown in figure 10 until the white clips close and the
module fits tightly into the DIMM socket (figure 11).
Figure 9 - DIMM notch
Figure 11 - DIMM module clip after installation
To remove the DIMM module press down the white clips and the module is ejected
from the socket.
