Quick Reference
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.
