Main Memory
NOTE
To be fully compliant with all applicable Intel
®SDRAM memory specifications, the
board should be populated with DIMMs that support the Serial Presence Detect (SPD)
data structure. If your memory modules do not support SPD, you will see a
notification to this effect on the screen at power up. The BIOS will attempt to
configure the memory controller for normal operation.
The Desktop Board supports the following memory and interface:
•Four 240-pin Double Data Rate 3 (DDR3) SDRAM Dual Inline Memory Module
(DIMM) sockets with gold-plated contacts arranged in two channels
•2133 MHz to 1066 MHz DDR3 SDRAM Memory Modules
•Support for single- and dual-channel memory interleaving
•Unbuffered, non-registered single- or double-sided DIMMs with a voltage rating of
1.65 V or less
NOTE
Using a DIMM with a voltage rating higher than 1.65 V may damage the
processor.
•Non-ECC DDR3 memory
•Serial Presence Detect (SPD) memory only
•Up to 32 GB maximum total system memory using 8 GB DIMMs
NOTE
32-bit operating systems are limited to a maximum of 4 GB of memory.
These operating systems will report less than 4 GB because of the memory
used by add-in graphics cards and other system resources.

Intel®P67 Express Chipset
The Intel P67 Express Chipset consists of the Intel P67 Platform Controller Hub (PCH).
The PCH is the centralized controller for the board’s I/O paths.
Audio Subsystem
The onboard audio subsystem consists of the following components:
•Intel®P67 PCH
•Realtek ALC892 codec
The subsystem has the following headers and connectors:
•Back panel audio connectors, including an S/PDIF out optical port.
•Advanced jack sense for the back panel audio connectors that enables the audio
codec to recognize the device that is connected to an audio port
•High Definition Audio Front panel audio header that supports Intel HD Audio and
AC ‘97 Audio. This header provides mic in and line out signals for front panel audio
connectors.
•An onboard S/PDIF header
The audio subsystem supports the following features:
•A signal-to-noise (S/N) ratio of 97 dB
•Independent multi-streaming 8-channel (7.1) audio (using the back panel audio
connectors) and 2-channel audio (using the High Definition Audio front panel
header)
Table 3 lists the supported functions of front panel and back panel audio jacks.

USB Support
The Desktop Board supports USB 2.0 and USB 3.0. There are 14 USB 2.0 ports (eight
ports routed to back panel connectors and six ports routed to three onboard headers).
The USB 2.0 ports are high-speed, full-speed, and low-speed capable.
USB 3.0 is supported by two back panel connectors (blue). USB 3.0 ports are
backward compatible with USB 2.0 and USB 1.1 devices. The USB 3.0 ports are
SuperSpeed, high-speed, full-speed, and low-speed capable.
Serial ATA Support
Intel Desktop Board DP67BG supports two onboard 6.0 Gb/s Serial ATA (SATA)
channels and four onboard 3.0 Gb/s SATA channels. The board also provides one
3.0 Gb/s external SATA (eSATA) channel via a back panel connector.
The onboard SATA channels provided by the PCH support Intel Rapid Storage
Technology which provides the following RAID (Redundant Array of Independent
Drives) levels:
•RAID 0 - data striping
•RAID 1 - data mirroring
•RAID 0+1 (or RAID 10) - data striping and data mirroring
•RAID 5 - distributed parity
Legacy I/O
Intel Desktop Board DP67BG includes a legacy I/O controller that provides the
following I/O features:
•Consumer Infrared (CIR) support
•Low pin count (LPC) interface
•Intelligent power management, including a programmable wake up event interface
•PCI power management support
Expandability
Intel Desktop Board DP67BG provides the following expansion capability:
•One PCI Express 2.0 x16 port
•One PCI Express 2.0 x8 port (x8 electrical; x16 compatible)
•Three PCI Express 2.0 x1 ports
•Two PCI bus connectors

Desktop Board Features
19
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI/PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 65.
Serial ATA Auto Configuration
If you install a Serial ATA device (such as a hard drive) in your computer, the auto-
configuration utility in the BIOS automatically detects and configures the device for
your computer. You do not need to run the BIOS Setup program after installing a
Serial ATA. You can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.
PCI* and PCI Express*Auto Configuration
If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express
auto-configuration utility in the BIOS automatically detects and configures the
resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need
to run the BIOS Setup program after you install a PCI/PCI Express add-in card.
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
•The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
•If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the supervisor or user
password was entered.
•Setting a user password restricts who can boot the computer. The password
prompt is displayed before the computer is booted. If only the supervisor
password is set, the computer boots without asking for a password. If both
passwords are set, you can enter either password to boot the computer.

For instructions on resetting the password, go to Clearing Passwords on page 56.

Back to BIOS Button
The back panel Back to BIOS button (Figure 3, A) duplicates the functionality of the
BIOS configuration jumper (see Setting the BIOS Configuration Jumper on page 55)
with the following exceptions:
•It can only be used to force the board to power on to the BIOS Maintenance Menu
using default values but it will retain all previously saved changes.
•It cannot be used to override passwords set in the BIOS.
•It cannot be used to invoke BIOS recovery mode.
The button glows red when it is activated.
NOTE
Using the Back to BIOS button does not set the board to the factory BIOS
defaults. To restore settings to the factory defaults, use the <F9> key once
BIOS setup mode is active.
Figure 3. Location of the Back to BIOS Button
Hardware Management
The hardware management features of Intel Desktop Board DP67BG enable the board
to be compatible with the Wired for Management (WfM) specification. The board has
several hardware management features including the following:
•Fan speed monitoring and control
•Thermal and voltage monitoring
•Chassis intrusion detection
Hardware Monitoring and Fan Speed Control
The features of the hardware monitoring and fan speed control include:
•Monitoring of power supply voltages to detect levels above and below acceptable
values
•Smart fan control provided by the legacy I/O controller, delivering acoustically-
optimized thermal management. Fan speed controllers and sensors are integrated
into the legacy I/O controller.
