2. Setting up the mainbaord
Before assembling the mainboard into the PC case we recommend you to perform.
1. CPU Installation
2. DDR Memory Insertion
After the mainboard is fitted into the case, you may
3. Install Add-on VGA or PCI cards
4. Connect the internal cables and wires
5. Connect your external peripherals to the rear I/O port
3. Installation
3.1 CPU Installation
Pin1
English
Step 1
Open the socket by raising
the actuation lever.
The CPU is keyed to prevent incorrect insertion, do not
force the CPU into the socket. If it does not go in easily,
check for mis-orientation.
Step 2
a) Align pin 1 on the CPU with pin 1 on the CPU socket as
shown above. Insert the CPU and make sure it is fully
inserted into the socket.
b) Close the socket by lowering and locking the actuation lever.
5
English
Step 3
Apply thermal compound
to the top of the CPU
surface and install the
heatsink as shown.
• Installing without a cooling fan will cause CPU overheat and damage the CPU.
• Apply heatsink thermal compound/paste to the CPU.
• Do not install a CPU over 50 times to avoid bending the pins and damaging the CPU.
Step 4
Install the cooling fan
assembly. Press the two
clips in the direction shown
above to secure its postion.
Step 5
Plug the cooling fan power
into the mainboard’s CPU fan
connector. The installation is
complete.
3.2 DDR Memory Insertion
The mainboard accommodates two PC2100/PC2700/PC3200 184-pin DIMMs (Dual In-line
Memory Modules):
• Supports up to 2.0GB of 266/333/400MHz DDR SDRAM.
• Supports unbuffered non-ECC DIMMs.
• DDR SDRAM supports 64, 128, 256, 512MB and 1GB DIMM modules.
• Supports DRAM configurations defined in the JEDEC DDR DIMM specification.

* With DDR333, adaptive synchronization
aligns to the closest FSB to memory clock
ratio, setting the memory channel to 320MHz.
To install, align the notch on the
DIMM module with the connector.
Press straight down as shown in the
figure until the white clips close and
the module fits tightly into the
DIMM socket.

3.3 VGA and PCI card installation
To install a VGA card into the AGP slot or a PCI expansion card:
1. Remove the bracket (on the PC case) for the slot you intend to use.
2. Firmly press down the card into the slot until it is completely seated. For an AGP
card ensure the AGP slot clicker is locked as shown in the picture below.
3. Secure the card's bracket to the PC case with a screw.
The AGP slot supports only newer VGA cards with 1.5V specifications.
