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

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

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.
