3.2 Installation You Have to Know
Installing CPU
This socket supports FC-LGA4 package CPU, which is the latest CPU package
developed by Intel. Other forms of CPU package are impossible to be fitted in.
Pull CPU socket lever and plate up.
1. Remove plastic cap from CPU socket plate.
2. Locate Pin 1 in the socket and look for a golden arrow on the CPU upper
interface. Match Pin 1 and golden arrow. Then insert the CPU into the
socket.
3. Press down the CPU socket plate and lever to finish CPU installation.
Warning:If you do not match the CP U
socket Pin 1 and CPU golden arrow well,
you may damage the CPU. And please don’t
touch CPU socket pins when installing CPU.
Note: It’s strongly recommended by
Intel to use thermal paste properly to avoid
over-heat generated from Prescott CPU .

Connecting CPU and System Fans
Plug the CPU fan cable to the 4-pin CPUFAN connector. If you have chassis fan,
you can also plug chassis fan in SYSFAN1 or SYSFAN2 connector.

Note: The tabs of the
DIMM slot will clip to hold the
DIMM in place when the DIMM
touches the slot’s bottom.

Maximum The Performance of the Dual Channel
To obtain the highest performance of Dual Channel, the configuration of DIMM
must meet the following conditions.
MatchedDIMM configuration in each channel
● Same density (128MB~1GB)
● Same DRAM bus width (x8 or x16)
● Either single-sided or double-sided
Note: Using memory modules of different
chip and density will cause system unstable.
When dual channel mode is successfully enabled, the screen will show “Dual
Channel Mode Enabled” while entering POST screen.
13
Connecting IDE and Floppy Cables
Connect the 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy
connector and IDE connector. Be careful of the pin1 orientation. Wrong
orientation may cause system damage.
