Pre-installation PrecautionsPre-installation Precautions

Take note of the following precautions before you install motherboard 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.

775-Pin Socket Overview

Before you insert the 775-LAND CPU into the socket, please check if the CPU surface is unclean or if there is any bent pin on the socket. Do not force to insert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged.

ASRock 775i945GZ 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 Ca p (Pick a nd 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.

1. It is recommended to use the cap tab to handle and avoid kicking off the PnP cap.

2. This cap must be placed if returning the motherboard for after service.

Step 4. Close the socket:

Step 4-1. Rotate the load plate onto the IHS. Step 4-2. While pressing down lightly on load

plate, engage the load lever.

Step 4-3. Secure load lever with load plate tab

under retention tab of load lever.

Installation of CPU Fan and HeatsinkInstallation 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.

If you press down the fasteners without rotating them clockwise, the heatsink cannot be secured on the motherboard.

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.

2.3 Installation of Memory Modules (DIMM)2.3 Installation of Memory Modules (DIMM)

775i945GZ motherboard provides two 240-pin DDRII (Double Data Rate) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install two identical (the same brand, speed, size and chip-type) memory modules in the DD RII DIMM slots to a ctivate Dual Cha nnel Memory Technology . Otherwise, it will operate at single channel mode.

1. It is not allowed to install a DDR memory module into DDRII slot; otherwise, this motherboard and DIMM may be damaged.

2. If you install only one memory module or two non-identical memory modules, it is unable to a ctivate the Dual Cha nnel Memory Technology.

Please make sure to disconnect power supply before adding or removing DIMMs or the system components.

Step 1. Unlock a DIMM slot by pressing the retaining clips outward. Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the brea k

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.

Step 3. 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.
