Pre-installation Precautions
Take note of the following precautions before you install mother-
board components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
2. To avoid damaging the motherboard components due to static
electricity, NEVER place your motherboard directly on the carpet
or the like. Also remember to use a grounded wrist strap or touch
a safety grounded object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded
antstatic pad or in the bag that comes with the component.
5. When placing screws into the screw holes to secure the
motherboard to the chassis, please do not over-tighten the
screws! Doing so may damage the motherboard.

Step 1. Open the socket:
Step 1-1. Disengaging the lever by depressing
down and out on the hook to clear
retention tab.
Step 1-2. Rotate the load lever to fully open po-
sition at approximately 135 degrees.
Step 1-3. Rotate the load plate to fully open po-
sition at approximately 100 degrees.
Step 2. Insert the 775-LAND CPU:
Step 2-1. Hold the CPU by the edges where are
marked with black lines.
Step 2-2. Orient the CPU with IHS (Integrated
Heat Sink) up. Locate Pin1 and the two
orientation key notches.
For proper inserting, please ensure to match the two orientation key
notches of the CPU with the two alignment keys of the socket.
Step 2-3. Carefully place the CPU into the socket
by using a purely vertical motion.
Step 2-4. Verify that the CPU is within the socket
and properly mated to the orient keys.
Step 3. Remove PnP Cap (Pick and Place Cap):
Use your left hand index finger and thumb to
support the load plate edge, engage PnP cap
with right hand thumb and peel the cap from the
socket while pressing on center of PnP cap to
assist in removal.

Installation of CPU Fan and Heatsink
For proper installation, please kindly refer to the instruction manuals of your CPU fan
and heatsink.
Below is an example to illustrate the installation of the heatsink for 775-LAND CPU.
Step 1. Apply thermal interface material onto center
of IHS on the socket surface.
Step 2. Place the heatsink onto the socket. Ensure
fan cables are oriented on side closest to the
CPU fan connector on the motherboard
(CPU_FAN1, see page 2, No. 5).
Step 3. Align fasteners with the motherboard
throughholes.
Step 4. Rotate the fastener clockwise, then press
down on fastener caps with thumb to install
and lock. Repeat with remaining fasteners.
Ifyoupress downthefastenerswithout rotatingthem clockwise,theheatsinkcannotbe

Step 5. Connect fan header with the CPU fan
connector on the motherboard.
Step 6. Secure excess cable with tie-wrap to ensure
cable does not interfere with fan operation or
contact other components.

775Dual-880Pro motherboard provides two 184-pin DDR (Double Data Rate)
DIMM slots and two 240-pinDDRIIDIMM slots, and supportsDual Channel Memory
Technology. For dual channel configuration, you always need to install identi-
cal (the same brand, speed, size and chip-type)DDRDIMM pair in the slots of the
same color. In other words, you have to install identical DDR DIMM pair in Dual
Channel A (DDRII1 and DDRII2; Yellow slots; see p.2 No.6) or identical DDR
DIMM pair in Dual Channel B (DDR1 andDDR2; Blue slots; see p.2No.7), so that
Dual Channel Memory Technology can be activated. You may refer to the Dual

Installing a DIMM
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
STEP1: Unlock a DIMM slot by pressing the retaining clips outward.
STEP2: Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into the
slot at incorrect orientation.
STEP3: Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and the DIMM is properly seated.
