This socket supports Intel FC-LGA4 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 CPU socket lever to finish CPU
installation.

Installing Memory Modules
DIMM slots are designed in Navy Blue and Electronic Blue which are very easy to
recognize. Insert the module straight down to the DIMM slot with both hands and
press down firmly until the DIMM module is securely in place.

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)
As long as you insert memory modules of same density into Channel 1 (DIMM A1
& DIMM A2) and Channel 2 (DIMM B1 & DIMM B2), dual channel mode will be
enabled.
DIMM A1 + DIMM A2 = DIMM B1 + DIMM B2
Ex: if you insert 1GB memory module into DIMM A1 and DIMM A2, dual channel
mode will be enabled when DIMM B1 + DIMM B2 = 1GB
● Same DRAM bus width (x8 or x16)
● Either single-sided or double-sided
Note: Using memory modules of dif ferent chip will
cause system unstable.
When dual channel mode is successfully enabled, the screen will show “Dual
Channel Mode Enabled” while entering POST screen.

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.

Connecting Front Panel Cable
Attach the power LED, speaker and reset switch connectors to the corresponding
pins. If you enable “Suspend Mode” item in BIOS Setup, the ACPI & Power LED
will keep flashing while the system is in suspend mode.
Locate the power switch cable from your ATX housing, which is a 2-pin female
connector from the housing front panel. Plug this connector to the soft-power
switch connector marked SPWR.

Connecting ATX Power Cables
This motherboard comes with a 24-pinATX power connector and 4-pin 12V ATX
power connector as shown below. Make sure you plug them in the right direction.
We strongly recommend you to insert the 4-pin connector before connecting the
24-pin connector.
Note: If you don’t
have 24-pin ATX power
cable, please plug your
.ATX power cable
20-pin
leftwards into the ATX
power connector as
shown leftwards.
