This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to an outlet on a circuit other than the one to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Canadian Department of Communications Compliance Statement
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus set out in the
Radio Interference Regulations of the Canadian Department of Communications.
Le présent appareil numerique német pas de bruits radioélectriques dépassant les limites applicables aux appareils
numériques de la classe B prescrites dans le Réglement sur le broullage radioélectrique édictépar le ministére des
Communications du Canada.

Processor
CAUTION
Failure to use an ATX12V power supply, or not connecting the 12 V processor core voltage power
supply connector to Desktop Board D875PBZ may result in damage to the desktop board and/or
power supply.
Desktop Board D875PBZ supports a single Intel Pentium 4 processor. Processors are not included
with the desktop board and must be purchased separately.
The processor connects to the Intel desktop board through the mPGA478-pin socket. The Intel
Pentium 4 processor may be removed and replaced to accommodate supported higher speed
processors.
Desktop Board D875PBZ supports the processors listed in Table 2.

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 system memory as defined below:
• Up to four dual channel 184-pin Double Data Rate (DDR) SDRAM DIMMs connectors with
gold-plated contacts. Supported memory configurations are:
Memory Speed Processor FSB Memory Speed Outcome
DDR400 Intel Pentium 4 processor 800 MHz 400 MHz
Intel Pentium 4 processor 800 MHz 320 MHzDDR333
Intel Pentium 4 processor 533 MHz 333 MHz
• Support for:
 Unbuffered, non-registered single or double-sided DIMMs
 Serial Presence Detect (SPD) memory only
 Support for Suspend to RAM (STR), S3 ACPI state
 ECC and non-ECC RAM (ECC support must be enabled in BIOS)
 2.5 V memory
• Support for 128 Mb, 256 Mb, and 512 Mb memory technologies for the following memory
configurations:
 Up to 1.0 GB utilizing 128 Mb technology
 Up to 2.0 GB utilizing 256 Mb technology
 Up to 4.0 GB utilizing 512 Mb technology
NOTE
System resources (such as PCI and AGP) require physical memory address locations that reduce
available memory addresses above 3 GB. This may result in less than 4 GB of memory being
available to the operating system and applications.

• Intel 82801ER I/O Controller Hub (ICH5R) with AHA bus supporting Intel RAID Technology
• Firmware Hub (FWH)
Performance Acceleration Technology (PAT) provides optimum memory pathways to enhance
memory performance; it requires processors with 800 FSB frequency and DDR400 memory.
Related Link:
Go to the following link for more information about the Intel 875P chipset:
http://developer.intel.com/design/nav/pcserver.htm
Input/Output (I/O) Controller
The super I/O controller features the following:
• Low pin count (LPC) interface
• One serial port
• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port
(EPP) support
• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• PS/2-style mouse and keyboard interfaces
• Interface for one 1.2 MB, 1.44 MB, or 2.88 MB diskette drive
• Intelligent power management, including a programmable wake up event interface
• PCI power management support
LAN Subsystem
The Intel®PRO/1000 CT desktop connection provides 2x gigabit network performance over
Communication Streaming Architecture (CSA). The LAN subsystem provides the following:
• 10/100/1000 Gigabit Ethernet (Intel 82547EI)
• Direct link to the memory controller hub with CSA
• Configurable EEPROM that contains the MAC address
• Support for:
 ASF 2.0
 RJ-45 connector with status indicator LEDs

RJ-45 LAN Connector LEDs
Two LEDs are built into the RJ-45 LAN connector. Table 3 describes the LED states when the
board is powered up and the 10/100/1000 Gigabit Ethernet LAN subsystem is operating.

Hi-Speed USB 2.0 Support
NOTE
Use a shielded cable that meets the requirements for a full-speed USB device. Computer systems
that have an unshielded cable attached to a USB port might not meet FCC Class B requirements,
even if no device or a low-speed USB device is attached to the cable.
NOTE
USB devices are limited to USB 1.1 transfer rates prior to operating system and driver
initialization.
The desktop board supports up to eight USB 2.0 ports via ICH5R; six ports routed to the back
panel and two routed to the internal USB 2.0 header. USB 2.0 ports are backward compatible with
USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer
rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports to USB 1.1 operation. This
may be required to accommodate operating systems that do not support USB 2.0.

Intel Desktop Board D875PBZ Product Guide
20
IDE Support
Enhanced IDE Interface
The ICH5R’s IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks, CD-ROM drives, and Iomega Zip*drives. The interface
supports:
• Up to four IDE devices (such as hard drives)
• ATAPI-style devices (such as CD-ROM drives)
• Older PIO Mode devices
• Ultra DMA-33 and ATA-66/100 protocols
• Laser Servo (LS-120) drives
SCSI LED Connector
The SCSI hard drive LED connector is a 1x2-pin connector that allows an add-in SCSI controller
(or other add-in card hard drive controller) to use the same LED as the onboard IDE controller.
Serial ATA (SATA)
The ICH5Rs Serial ATA interface handles the exchange of data between the processor and SATA
devices. The controller supports:
• Transfer rate of 150 MB/sec
• Up to two SATA devices
• RAID 0 (striping) support (for Windows XP only)
• PIO and DMA modes
Accelerated Graphics Port (AGP)
NOTE
The AGP connector is keyed for 1.5 V and 0.8 V AGP cards only. Do not attempt to install a legacy
3.3 V AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V AGP cards.
AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics.
AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices.
The AGP 3.0 connector supports 8x, 4x, and 1x add-in cards.
Related Links:
For information about installing the AGP card, see page 37 in Chapter 2.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.
The BIOS can be updated by following the instructions on page 53 in Chapter 3.
