3. Installing Processor
This socket supports Micro-FC-PGA2 package CPU, which is the latest CPU package
developed by Intel. Other forms of CPU package are impossible to be fitted in.

CPU Pin 1 and cut edge
4. Installing CPU & System Fan
Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan, you
can also plug it on System Fan (FAN2) or FAN3 (AUX Fan) connector.
FAN2 Connector
1.
Pull up the CPU socket lever and up to
90-degree angle.
2.
Locate Pin 1 in the socket and look for
a (golden) cut edge on the CPU upper
interface. Match Pin 1 and cut edge.
Then insert the CPU into the socket.
3.
Press down the CPU socket lever and
finish CPU installation.
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well, it
may damage the CPU.

5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
The CPU core voltage will be automatically detected. It is not necessary to set CPU core
voltage.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through the
BIOS setup, and no jumpers or switches are needed.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setting
Core Frequency = CPU FSB Clock * CPU Ratio
CPU Ratio
8x, 9x, 10x... 21x, 22x, 23x, 24x

may not be able to adjust the
clock ratio in BIOS manually.
