2. Setting up the mainboard
Before assembling the mainboard into the PC case we recommend you to do the following:
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 (Optional)
4. Connect the internal cables and wires
5. Connect your external peripherals to the rear I/O port
3.1 CPU Installation
3. Installation
Step 1
Open load plate ( A ) , DO NOT touch
socket contacts ( B ).
Step 2
Remove protective cover ( C ) from load
plate. Please do not discard the protective
cover. Always replace the protective cover
if the processor is removed from the socket.

English
Step 3
Remove the processor from the protective
cover. Do not touch the bottom of the
processor. The processor cover should not
be discarded. Always replace the processor
cover if the processor is removed from the
socket.
Step 4
Hold the processor with thumb and index
fingers as shown. Ensure fingers align to the
socket cutouts ( D ) , processor notches ( E )
align to socket convexes ( F ). Place the
processor straight down without tilting or
sliding in the socket.
Step 5
Place the fan heatsink onto the mainboard
with the fasteners align to the holes. Be care
not to damage the thermal interface material
attached to the bottom of the heatsink.
Rotate the clips 90 degrees to lock the CPU
cooler in place.
Connect the fan cable to the mainboard
header JCPU_FAN.

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.

3.3 VGA and PCI card installation
This mainboard is equipped with on-chip graphics engine, you may connect a VGA monitor
directly to its rear port. However, if you need to install VGA card follow the steps below.
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.
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.
The AGP slot supports only newer VGA cards with 1.5V specifications.
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.
