2. Installation

Pre-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.

2.1CPU Installation

For the installation of Intel 775-LAND CPU, please follow the steps below.

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 position at approximately 135 degrees.

Step 1-3. Rotate the load plate to fully open position 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.

1 1

English

ASRock 775i945GZ Motherboard

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.

2.2Installation 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.

English

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.

ASRock 775i945GZ Motherboard

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 DDRII DIMM slots to activate Dual Channel 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 activate the Dual Channel Memory Technology.

Installing a DIMM

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 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.

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.

ASRock 775i945GZ Motherboard

2.4 Expansion Slots (PCI, HDMR and AGI Express Slots)

There are 3 PCI slots, 1 HDMR slot and 1 AGI Express slot (PCI Express x4) on this motherboard.

PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface.

HDMR slot: HDMR slot is used to insert a HDMR card (optional) with v.92 Modem functionality.

AGI Express slot (PCI Express x4):

AGI Express slot (PCI Express x4) is used to install PCI Express expansion cards. For the information of the compatible PCI Express VGA cards, please refer to the “Supported PCI Express VGA Card List for AGI Express Slot (PCI Express x4)” on page 9.

1.If you install the add-on PCI Express VGA card, BIOS setup will automatically disable the onboard VGA.

2.Please make sure to set the BIOS onboard VGA selection into “Enabled” if you want this motherboard to support Surround Display. Then the onboard VGA in Windows will be the primary VGA card.

Installing an expansion card

Step 1. Before installing the expansion card, please make sure that the power supply is switched off or the power cord is unplugged. Please read the documentation of the expansion card and make necessary hardware settings for the card before you start the installation.

Step 2. Remove the bracket facing the slot that you intend to use. Keep the screws for later use.

Step 3. Align the card connector with the slot and press firmly until the card is completely seated on the slot.

Step 4. Fasten the card to the chassis with screws.
