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.

Any changes or modifications to the equipment not expressly approved by Intel Corporation could void the user’s authority to operate the equipment.

Tested to comply with FCC standards for home or office use.

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 édicté par le ministére des Communications du Canada.

Desktop Board Features

Processor

CAUTION

Failure to use the appropriate power supply and/or not connecting the 12 V (2 x 2 pin) power connector to the desktop board may result in damage to the board, or the system may not function properly.

Desktop Board DG965RY supports an Intel processor in the LGA775 package. Processors are not included with the desktop board and must be purchased separately. The processor connects to the desktop board through the LGA775 socket.

The supported processors list for Desktop Board DG965RY is located on the web at: http://support.intel.com/support/motherboards/desktop/

Related Links:

Go to the following page for more information about:

Instructions on installing or upgrading the processor, page 29 in Chapter 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 the dual or single channel memory configurations defined below.

Four 240-pin Double Data Rate 2 (DDR2) SDRAM Dual Inline Memory Module (DIMM) connectors with gold-plated contacts.

Support for:

Unbuffered, non-registered single or double-sided DIMMs

Non-ECC DDR2 800/667/533 MHz memory

Serial Presence Detect (SPD) memory only

Memory configurations listed below:

Up to 2.0 GB utilizing 256 Mb technology

Up to 4.0 GB utilizing 512 Mb or 1 Gb technology

Up to 8.0 GB utilizing 1 Gb technology

Desktop Board Features

Hi-Speed USB 2.0 Support

NOTE

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. Use a shielded cable that meets the requirements for a fullspeed USB device.

The desktop board supports up to 10 USB 2.0 ports via ICH8 (six ports routed to the back panel and four ports routed to two internal USB 2.0 headers). 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.

Enhanced IDE Interface

The ICH8’s IDE interface handles the exchange of information between the processor and peripheral devices such as hard disk drives and CD-ROM drives. The interface supports:

Up to two 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

Serial ATA

The desktop board supports four Serial ATA channels (3.0 Gb/s) via ICH8, connecting one device per channel.

Expandability

For system expansion, the desktop board provides the following:

Three PCI Express x1 connectors

One PCI Express x 16 connector

Three PCI bus connectors

Intel Desktop Board DG965RY Product Guide

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI Express and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Serial Peripheral Interface (SPI) Flash.

The BIOS can be updated by following the instructions on page 59 in Chapter 3.

Serial ATA and IDE Auto Configuration

If you install a Serial ATA or IDE 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 or IDE device. 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.

Desktop Board Features

Hardware Management Features

The hardware management features of Desktop Board DG965RY 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

Intel Quiet System Technology fan speed control, delivering acoustically-optimized thermal management

Fan speed controllers and sensors integrated into the ICH8

Thermal sensors in the processor, GMCH, and ICH8

Thermally monitored closed-loop fan control, for all on-board fans, that can adjust fan speed or switch the fans off as needed

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 26 on page 49 for the location of the chassis intrusion header.
