should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This allows the BIOS to read the SPD data and program the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory
is installed, the BIOS will attempt to correctly configure the memory settings, but
performance and reliability may be impacted or the DIMMs may not function under the
determined frequency.
Table 3 lists the supported DIMM configurations.

Regardless of the DIMM type used, the memory frequency will either be equal to or
less than the processor system bus frequency. For example, if DDR2 800 memory is
used with a 533 MHz system bus frequency processor, the memory will operate at
533 MHz. Table 4 lists the resulting operating memory frequencies based on the
combination of DIMMs and processors.

1.4.1 Memory Configurations
The Intel 82G965 GMCH supports the following types of memory organization:
• Dual channel (Interleaved) mode. This mode offers the highest throughput for
real world applications. Dual channel mode is enabled when the installed memory
capacities of both DIMM channels are equal. Technology and device width can vary
from one channel to the other but the installed memory capacity for each channel
must be equal. If different speed DIMMs are used between channels, the slowest
memory timing will be used.
• Single channel (Asymmetric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a
single DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the other. If different speed DIMMs are
used between channels, the slowest memory timing will be used.
• Flex mode. This mode provides the most flexible performance characteristics.
The bottommost DRAM memory (the memory that is lowest within the system
memory map) is mapped to dual channel operation; the topmost DRAM memory
(the memory that is nearest to the 8 GB address space limit), if any, is mapped to
single channel operation. Flex mode results in multiple zones of dual and single
channel operation across the whole of DRAM memory. To use flex mode, it is
necessary to populate both channels.

Product Description
1.5.1.2 Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through highly efficient
memory utilization. DVMT ensures the most efficient use of available system memory
for maximum 2-D/3-D graphics performance. Up to 256 MB of system memory can be
allocated to DVMT on systems that have 512 MB or more of total system memory
installed. DVMT returns system memory back to the operating system when the
additional system memory is no longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the
BIOS Setup program) for compatibility with legacy applications. An example of this
would be when using VGA graphics under DOS. Once loaded, the operating system
and graphics drivers allocate additional system memory to the graphics buffer as
needed for performing graphics functions.
NOTE
�
The use of DVMT requires operating system driver support.
1.5.1.3 Configuration Modes
A list of supported modes for the Intel GMA X3000 graphics controller is available as a
downloadable document.
For information about Refer to
Supported video modes for the board Section 1.2, page 15
1.5.1.4 Advanced Digital Display (ADD2/MEC) Card Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
200 MHz pixel clock to the PCI Express x16 connector. The SDVO ports can be paired
for a dual channel configuration to support up to a 400 MHz pixel clock. When an
ADD2/MEC card is detected, the Intel GMA X3000 graphics controller is enabled and
the PCI Express x16 connector is configured for SDVO mode. SDVO mode enables the
SDVO ports to be accessed by the ADD2/MEC card. An ADD2/MEC card can either be
configured to support simultaneous display with the primary VGA display or can be
configured to support dual independent display as an extended desktop configuration
with different color depths and resolutions. ADD2/MEC cards can be designed to
support the following configurations:
• TV-Out (composite video)
• Transition Minimized Differential Signaling (TMDS) for DVI 1.0
• Low Voltage Differential Signaling (LVDS)
• Single device operating in dual channel mode
• VGA output
• HDTV output
• HDMI/UDI support (when used with the HD Audio Link)
25
Intel Desktop Board DG965RY Technical Product Specification
1.5.2 USB
The board supports up to 10 USB 2.0 ports, supports UHCI and EHCI, and uses UHCI-
and EHCI-compatible drivers.
The ICH8 provides the USB controller for all ports. The port arrangement is as
follows:
• Six ports are implemented with stacked back panel connectors
• Four ports are routed to two separate front panel USB headers
NOTE
�
Computer systems that have an unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no device is attached to the cable. Use
shielded cable that meets the requirements for full-speed devices.
For information about Refer to
The location of the USB connectors on the back panel Figure 15, page 49
The location of the front panel USB headers Figure 16, page 50
1.5.3 Serial ATA Interfaces
The board provides four Serial ATA (SATA) connectors, which support one device per
connector.
1.5.3.1 Serial ATA Support
The ICH8’s Serial ATA controller offers four independent Serial ATA ports with a
theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed
on each port for a maximum of four Serial ATA devices. A point-to-point interface is
used for host to device connections, unlike Parallel ATA IDE which supports a
master/slave configuration and two devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the
operating system. The Serial ATA controller can operate in both legacy and native
modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14
and 15). In Native mode, standard PCI Conventional bus resource steering is used.
Native mode is the preferred mode for configurations using the Windows* XP and
Windows 2000 operating systems.
NOTE
�
Many Serial ATA drives use new low-voltage power connectors and require adaptors or
power supplies equipped with low-voltage power connectors.
For more information, see: http://www.serialata.org/.
For information about Refer to
The location of the Serial ATA connectors Figure 16, page 50
26
Product Description
1.5.4 Parallel IDE Interface
The Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The
Parallel ATA IDE interface supports the following modes:
• Programmed I/O (PIO): processor controls data transfer.
• 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to
16 MB/sec.
• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 33 MB/sec.
• ATA-66: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is
device driver compatible.
• ATA-100: DMA protocol on IDE bus allows host and target throttling. The ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up
to 88 MB/sec.
• ATA-133: DMA protocol on IDE bus allows host and target throttling. The ATA-133
logic is designed to achieve read transfer rates up to 133 MB/sec and write transfer
rates in excess of 100 MB/sec.
� NOTE
ATA-66, ATA-100, and ATA-133 are faster timings and require a specialized cable to
reduce reflections, noise, and inductive coupling.
The Parallel ATA IDE interface also supports ATAPI devices (such as CD-ROM drives)
and ATA devices. The BIOS supports Logical Block Addressing (LBA) and Extended
Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate
and translation mode to the BIOS.
For information about Refer to
The location of the Parallel ATA IDE connector Figure 16, page 50
1.5.5 Real-Time Clock, CMOS SRAM, and Battery
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When
the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at
25 ºC with 3.3 VSB applied.
� NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded
into CMOS RAM at power-on.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 1 on page 12 shows the location of the battery.

1.10.1.2 Two-Watt Standby
In 2001, the U.S. government issued an executive order requiring a reduction in
power for appliances and personal computers. This board meets that requirement by
operating at 1.5 W (or less) in S5 (Standby) mode. Two-Watt operation applies only
to the S5 state when the computer is turned off, but still connected to AC power.
Two-Watt operation does not apply to the S3 (Suspend to RAM) or S4 (Suspend to
disk) states.
36
Product Description
Newer energy-efficient power supplies using less than 0.5 W (in Standby mode) may
also be needed to achieve this goal.
1.10.1.3 Wake-up Devices and Events
Table 9 lists the devices or specific events that can wake the computer from specific
states.

Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to
Power On will enable a wake-up event from LAN in the S5 state.
NOTE
�
The use of these wake-up events from an ACPI state requires an operating system
that provides full ACPI support. In addition, software, drivers, and peripherals must
fully support ACPI wake events.
1.10.2 Hardware Support
CAUTION
Ensure that the power supply provides adequate +5 V standby current if LAN wake
capabilities and Instantly Available PC technology features are used. Failure to do so
can damage the power supply. The total amount of standby current required depends
on the wake devices supported and manufacturing options.
The board provides several power management hardware features, including:
• Power connector
• Fan headers
• LAN wake capabilities
• Instantly Available PC technology
• Resume on Ring
• Wake from USB
• Wake from PS/2 keyboard
• PME# signal wake-up support
• WAKE# signal wake-up support
37
Intel Desktop Board DG965RY Technical Product Specification
LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line.
Resume on Ring enables telephony devices to access the computer when it is in a
power-managed state. The method used depends on the type of telephony device
(external or internal).
NOTE
�
The use of Resume on Ring and Wake from USB technologies from an ACPI state
requires an operating system that provides full ACPI support.
1.10.2.1 Power Connector
ATX12V-compliant power supplies can turn off the system power through system
control. When an ACPI-enabled system receives the correct command, the power
supply removes all non-standby voltages.
When resuming from an AC power failure, the computer returns to the power state it
was in before power was interrupted (on or off). The computer’s response can be set
using the Last Power State feature in the BIOS Setup program’s Boot menu.
For information about Refer to
The location of the main power connector Figure 16, page 50
The signal names of the main power connector Table 26, page 54
1.10.2.2 Fan Headers
The function/operation of the fan headers is as follows:
• The fans are on when the board is in the S0 state.
• The fans are off when the board is off or in the S3, S4, or S5 state.
• Each fan header is wired to a fan tachometer input of the hardware monitoring and
fan control device.
• All fan headers support closed-loop fan control that can adjust the fan speed or
switch the fan on or off as needed.
• All fan headers have a +12 V DC connection.

Product Description
1.10.2.3 LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line from the power supply must be
capable of providing adequate +5 V standby current. Failure to provide adequate
standby current when implementing LAN wake capabilities can damage the power
supply.
LAN wake capabilities enable remote wake-up of the computer through a network.
The LAN subsystem PCI bus network adapter monitors network traffic at the Media
Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem
asserts a wake-up signal that powers up the computer. Depending on the LAN
implementation, the board supports LAN wake capabilities with ACPI in the following
ways:
• The PCI Express WAKE# signal
• The PCI bus PME# signal for PCI 2.3 compliant LAN designs
• The onboard LAN subsystem
1.10.2.4 Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line from the power supply
must be capable of providing adequate +5 V standby current. Failure to provide
adequate standby current when implementing Instantly Available PC technology can
damage the power supply.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-
RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the
power supply is off, and the front panel LED is amber if dual colored, or off if single
colored.) When signaled by a wake-up device or event, the system quickly returns to
its last known wake state. Table 9 on page 37 lists the devices and events that can
wake the computer from the S3 state.
The board supports the PCI Bus Power Management Interface Specification. Add-in
boards that also support this specification can participate in power management and
can be used to wake the computer.
The use of Instantly Available PC technology requires operating system support and
PCI 2.3 compliant add-in cards and drivers.
1.10.2.5 Resume on Ring
The operation of Resume on Ring can be summarized as follows:
• Resumes operation from ACPI S3 state
• Detects incoming call similarly for external and internal modems
• Requires modem interrupt be unmasked for correct operation
39
Intel Desktop Board DG965RY Technical Product Specification
1.10.2.6 Wake from USB
USB bus activity wakes the computer from ACPI S3 state.
NOTE
�
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.10.2.7 Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S3 state.
1.10.2.8 PME# Signal Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI
S3, S4, or S5 state (with Wake on PME enabled in BIOS).
1.10.2.9 WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S3, S4, or S5 state.
1.10.2.10 +5 V Standby Power Indicator LED
The +5 V standby power indicator LED shows that power is still present even when the
computer appears to be off. Figure 13 shows the location of the standby power
indicator LED.
CAUTION
If AC power has been switched off and the standby power indicator is still lit,
disconnect the power cord before installing or removing any devices connected to the
board. Failure to do so could damage the board and any attached devices.

2.1 Memory Map
2.1.1 Addressable Memory
The board utilizes 8 GB of addressable system memory. Typically the address space
that is allocated for PCI Conventional bus add-in cards, PCI Express configuration
space, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (total
system memory). On a system that has 8 GB of system memory installed, it is not
possible to use all of the installed memory due to system address space being
allocated for other system critical functions. These functions include the following:
• BIOS/ SPI Flash (8 Mbits)
• Local APIC (19 MB)
• Digital Media Interface (40 MB)
• Front side bus interrupts (17 MB)
• PCI Express configuration space (256 MB)
• GMCH base address registers, internal graphics ranges, PCI Express ports (up to
512 MB)
• Memory-mapped I/O that is dynamically allocated for PCI Conventional and PCI
Express add-in cards
• Base graphics memory support (1 MB or 8 MB)
41
Intel Desktop Board DG965RY Technical Product Specification
The amount of installed memory that can be used will vary based on add-in cards and
BIOS settings. Figure 14 shows a schematic of the system memory map. All installed
system memory can be used when there is no overlap of system addresses.

2.7 PCI Interrupt Routing Map
This section describes interrupt sharing and how the interrupt signals are connected
between the PCI bus connectors and onboard PCI devices. The PCI specification
specifies how interrupts can be shared between devices attached to the PCI bus. In
most cases, the small amount of latency added by interrupt sharing does not affect
the operation or throughput of the devices. In some special cases where maximum
performance is needed from a device, a PCI device should not share an interrupt with
other PCI devices. Use the following information to avoid sharing an interrupt with a
PCI add-in card.
PCI devices are categorized as follows to specify their interrupt grouping:
• INTA: By default, all add-in cards that require only one interrupt are in this
category. For almost all cards that require more than one interrupt, the first
interrupt on the card is also classified as INTA.
• INTB: Generally, the second interrupt on add-in cards that require two or more
interrupts is classified as INTB. (This is not an absolute requirement.)
• INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC
and a fourth interrupt is classified as INTD.
The ICH8 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI
interrupt sources either onboard or from a PCI add-in card connect to one of these
PIRQ signals. Some PCI interrupt sources are electrically tied together on the board
and therefore share the same interrupt. Table 16 shows an example of how the
PIRQ signals are routed.

PCI bus connector 2 INTC INTB INTA INTD
PCI bus connector 3 INTD INTC INTA INTB
IEEE-1394a controller INTA
NOTE
�
In PIC mode, the ICH8 can connect each PIRQ line internally to one of the IRQ signals
(3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15). Typically, a device that does not share a
PIRQ line will have a unique interrupt. However, in certain interrupt-constrained
situations, it is possible for two or more of the PIRQ lines to be connected to the same
IRQ signal. Refer to Table 14 for the allocation of PIRQ lines to IRQ signals in APIC
mode.
PCI interrupt assignments to USB ports and Serial ATA ports are dynamic.
2.8 Connectors and Headers
CAUTION
Only the following connectors have overcurrent protection: Back panel and front panel
USB, PS/2, and VGA.
The other internal connectors/headers are not overcurrent protected and should
connect only to devices inside the computer’s chassis, such as fans and internal
peripherals. Do not use these connectors/headers to power devices external to the
computer’s chassis. A fault in the load presented by the external devices could cause
damage to the computer, the power cable, and the external devices themselves.
This section describes the board’s connectors and headers. The connectors and
headers can be divided into these groups:
• Back panel I/O connectors (see page 49)
• Component-side connectors and headers (see page 50)

2.8.2.1 Add-in Card Connectors
The board has the following add-in card connectors:
• PCI Express x16: one connector supporting simultaneous transfer speeds up to
4 GBytes/sec of peak bandwidth per direction and up to 8 GBytes/sec concurrent
bandwidth
• PCI Express x1: three PCI Express x1 connectors. The x1 interface supports
simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per
direction and up to 500 MBytes/sec concurrent bandwidth
• PCI Conventional (rev 2.3 compliant) bus: three PCI Conventional bus add-in card
connectors. The SMBus is routed to PCI Conventional bus connector 2 only. PCI
Conventional bus add-in cards with SMBus support can access sensor data and
other information residing on the board.
Note the following considerations for the PCI Conventional bus connectors:
• All of the PCI Conventional bus connectors are bus master capable.
• SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI
Conventional bus add-in boards with SMBus support to access sensor data on the
board. The specific SMBus signals are as follows:
⎯ The SMBus clock line is connected to pin A40.
⎯ The SMBus data line is connected to pin A41.

Intel Desktop Board DG965RY Technical Product Specification
2.8.2.2 Power Supply Connectors
The board has the following power supply connectors:
• Main power – a 2 x 12 connector. This connector is compatible with 2 x 10
connectors previously used on Intel Desktop boards. The board supports the use
of ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables. When
using a power supply with a 2 x 10 main power cable, attach that cable on the
rightmost pins of the main power connector, leaving pins 11, 12, 23, and 24
unconnected.
• Processor core power – a 2 x 2 connector. This connector provides power
directly to the processor voltage regulator and must always be used. Failure to do
so will prevent the board from booting.

CAUTION
Do not move the jumper with the power on. Always turn off the power and unplug the
power cord from the computer before changing a jumper setting. Otherwise, the
board could be damaged.
Figure 20 shows the location of the jumper block. The jumper determines the BIOS
Setup program’s mode. Table 30 lists the jumper settings for the three modes:
normal, configure, and recovery. When the jumper is set to configure mode and the
computer is powered-up, the BIOS compares the processor version and the microcode
version in the BIOS and reports if the two match.

2.11 Electrical Considerations
2.11.1 DC Loading
Table 31 lists the DC loading characteristics of the board. This data is based on a DC
analysis of all active components within the board that impact its power delivery
subsystems. The analysis does not include PCI add-in cards. Minimum values assume
a light load placed on the board that is similar to an environment with no applications
running and no USB current draw. Maximum values assume a load placed on the
board that is similar to a heavy gaming environment with a 500 mA current draw per
USB port. These calculations are not based on specific processor values or memory
configurations but are based on the minimum and maximum current draw possible
from the board’s power delivery subsystems to the processor, memory, and USB
ports.
Use the datasheets for add-in cards, such as PCI, to determine the overall system
power requirements. The selection of a power supply at the system level is dependent
on the system’s usage model and not necessarily tied to a particular processor speed.

2.11.2 Fan Header Current Capability
CAUTION
The processor fan must be connected to the processor fan header, not to a chassis fan
header. Connecting the processor fan to a chassis fan header may result in onboard
component damage that will halt fan operation.
Table 32 lists the current capability of the fan headers.

Fan Header Maximum Available Current
Processor fan 3.0 A
Front chassis fan 1.5 A
Rear chassis fan 1.5 A
Auxiliary rear chassis fan 2.5 A
61
Intel Desktop Board DG965RY Technical Product Specification
2.11.3 Add-in Board Considerations
The board is designed to provide 2 A (average) of +5 V current for each add-in board.
The total +5 V current draw for add-in boards for a fully loaded board (all six
expansion slots and the PCI Express x16 connector filled) must not exceed 14 A.
2.11.4 Power Supply Considerations
CAUTION
The +5 V standby line from the power supply must be capable of providing adequate
+5 V standby current. Failure to do so can damage the power supply. The total
amount of standby current required depends on the wake devices supported and
manufacturing options.
System integrators should refer to the power usage values listed in Table 31 when
selecting a power supply for use with the board.
Additional power required will depend on configurations chosen by the integrator.
The power supply must comply with the indicated parameters of the ATX form factor
specification.
• The potential relation between 3.3 VDC and +5 VDC power rails
• The current capability of the +5 VSB line
• All timing parameters
• All voltage tolerances
62
Technical Reference
2.12 Thermal Considerations
CAUTION
o
A chassis with a maximum internal ambient temperature of 38 C at the processor fan
inlet is a requirement. Use a processor heat sink that provides omni-directional
airflow to maintain required airflow across the processor voltage regulator area.
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the
processor and/or voltage regulator or, in some instances, damage to the board. For a
list of chassis that have been tested with Intel desktop boards please refer to the
following website:
http://developer.intel.com/design/motherbd/cooling.htm
All responsibility for determining the adequacy of any thermal or system design
remains solely with the reader. Intel makes no warranties or representations that
merely following the instructions presented in this document will result in a system
with adequate thermal performance.
CAUTION
Ensure that the ambient temperature does not exceed the board’s maximum operating
temperature. Failure to do so could cause components to exceed their maximum case
temperature and malfunction. For information about the maximum operating
temperature, see the environmental specifications in Section 2.14.
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator circuit.
Failure to do so may result in damage to the voltage regulator circuit. The processor
o
voltage regulator area (shown in Figure 23) can reach a temperature of up to 85 C in
an open chassis.

2.13 Reliability
The Mean Time Between Failures (MTBF) prediction is calculated using component and
subassembly random failure rates. The calculation is based on the Bellcore Reliability
Prediction Procedure, TR-NWT-000332, Issue 4, September 1991. The MTBF
prediction is used to estimate repair rates and spare parts requirements.
The MTBF data is calculated from predicted data at 55 ºC. The Desktop Board
DG965RY MTBF is 121,751 hours.

3.1 Introduction
The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash
Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash
contains the BIOS Setup program, POST, the PCI auto-configuration utility, LAN
EEPROM information, and Plug and Play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision
code. The initial production BIOSs are identified as MQ96510A.86A.
When the BIOS Setup configuration jumper is set to configure mode and the computer
is powered-up, the BIOS compares the CPU version and the microcode version in the
BIOS and reports if the two match.
The BIOS Setup program can be used to view and change the BIOS settings for the
computer. The BIOS Setup program is accessed by pressing the
