Before You Begin

Warning and Cautions

WARNING

Disconnect the board’s power supply from its AC power source

before you connect or disconnect cables, or install or remove any

board components. Failure to do this can result in personal injury or

equipment damage. Some circuitry on the desktop board can

continue to operate even though the front panel power switch is off.

CAUTION

Electrostatic discharge (ESD) can damage desktop board components.

Install the board at an ESD-controlled workstation. If such a workstation

is not available, wear an antistatic wrist strap or touch the surface of the

antistatic package before handling the board.

CAUTION

Many of the midboard and front panel connectors provide operating

voltage (+5 V DC and +12 V DC, for example) to devices inside the

computer chassis, such as fans and internal peripherals. These

connectors are not overcurrent protected. Do not use these connectors

for powering devices external to the computer chassis. A fault in the load

presented by the external devices could cause damage to the computer,

the interconnecting cables, and the external devices themselves.

Safety and Regulatory Notice

See the Intel Desktop Boards D845GRG and D845GBV Product Guide for all

applicable regulatory compliance statements, product certification markings, and

safety and electromagnetic compatibility (EMC) standards and regulations these

desktop boards are compliant with.

Replacement battery warning label provided: Place the label inside the chassis

in an easy-to-see location near the battery but not on the board itself.

Intended uses: This product was evaluated as information technology

equipment (ITE) for home or office use when installed into an appropriate

computer chassis. Other end uses or locations may require further evaluation.

Memory Module Requirements

The desktop boards supports system memory as defined below:

• Up to two 184-pin Double Data Rate (DDR) 200/266 SDRAM Dual Inline

Memory Modules (DIMMs) with gold-plated contacts

• Unbuffered and non-registered single or double-sided DIMMs

• Serial Presence Detect (SPD) memory only

• Non-ECC and ECC DIMMs

• 2.5 V memory

✏NOTES

The Desktop Boards D845GRG and D845GBV have been designed to

support DIMMs based on 512 Mbit technology up to 2 GB, but this

technology has not been validated on these boards.

All memory components and DIMMs used with the desktop boards must

comply with the PC SDRAM specifications. These include the PC

SDRAM Specification (memory component specific), the PC Unbuffered

DIMM Specification. To view or download these specifications, refer to

this Intel World Wide Web site:

http://www.intel.com/technology/memory/pcsdram/

For information about vendors that support these memory requirements,

refer to the Desktop Boards D845GRG and D845GBV link on this Intel

World Wide Web site:

http://support.intel.com/support/motherboards/desktop/

Installation Steps

1 Installing the I/O Shield

The board comes with an I/O shield. When installed in the chassis, the shield

blocks radio frequency transmissions, necessary to pass emissions (EMI)

certification testing, protects internal components from dust and foreign objects,

and promotes correct airflow within the chassis.

Install the I/O shield before installing the board in the chassis. Place the shield

inside the chassis as shown in the following figure. Press the shield into place so

that it fits tightly and securely. If the shield doesn’t fit, obtain a properly sized

shield from the chassis supplier.

2 Installing the Desktop Board

CAUTION

Failure to use an ATX12V power supply, or not connecting the additional

power supply lead to the Desktop Boards D845GRG and D845GBV may

result in damage to the desktop board and/or power supply.

For more information on the ATX12V power supply, refer to the Intel

Desktop Boards D845GRG and D845GBV Product Guide on the Intel

Express Installer CD-ROM.

Refer to your chassis manual for specific instructions on installing and removing

the desktop board.

Secure the desktop board to the chassis standoffs using the screws. The Desktop

Board D845GRG is secured to the chassis with six and Desktop Board

D845GBV with eight screws. Refer to the board illustration on page 4 for the

location of the mounting holes.

3 Installing the Processor

To install the processor, follow these steps

1. Observe the precautions in “Before You Begin”on page 3.

2. Lift the processor socket lever.

3. Install the processor so that the corner with the triangle marking (A) is

aligned with the corner where the lever is attached to the socket.

4. Lower the lever back to its original position.

5. The desktop boards have an integrated processor fan heat sink retention

mechanism (RM). For instructions on how to install the processor fan heat

sink, refer to the boxed processor manual or the Intel World Wide Web

site at:

http://support.intel.com/support/processors/pentium4/intnotes478.htm

4 Installing the Memory Modules

CAUTION

Install memory in the DIMM sockets prior to installing the AGP video card

to avoid interference with the memory retention mechanism.

The Desktop Boards D845GRG and D845GBV’s two DIMM sockets are

arranged as Banks 0 and 1, as shown in the following figure. If installing a

single DIMM, install it in Bank 0.

To install DIMMs, follow these steps:

1. Remove the AGP video card if it interferes with the DIMM clips from

being easily opened and closed.

2. Align the small notch in the bottom edge of the DIMM with the key in the

socket.

3. Insert the bottom edge of the DIMM into the socket.

4. When the DIMM is inserted, push down on the top edge of the DIMM until

the retaining slips snap into place. Make sure the clips are firmly in place.

5 Installing an AGP Card

✏ NOTE

The D845GRG and D845GBV boards are only compatible with 1.5 V AGP

cards.

The Desktop Boards D845GRG and D845GBV have an integrated AGP card

retention mechanism (RM). Follow these instructions to install an AGP card:

1. Place the AGP card in the AGP connector.

2. Press down on the card until it is completely seated in the connector and the

card retention notch snaps into place below the RM.

3. Secure the card’s metal bracket to the chassis back panel with a screw.

To remove the AGP card, push back on the RM lever (A) until the retention pin

completely clears the notch in the card.

7 Attaching the IDE Drives

The Intel®boxed desktop board package includes two IDE cables. Either cable

can connect two drives to the desktop board. The cables support the Ultra

DMA-33 (40-contact, 40-conductor) or ATA-66/100 (40-contact, 80-conductor)

transfer protocols and are backward compatible with drives using slower IDE

transfer protocols.

The cable will work correctly only when oriented as shown in the following

figure. For correct cable function:

1. Observe the precautions in “Before You Begin”on page 3.

2. Attach the cable end with the single connector (A) to the board.

3. Attach the cable end with the two closely spaced connectors (B) to the

drives.
