1.3 Processor

The board is designed to support Intel Pentium 4 processors in an LGA775 processor socket with an 800 or 533 MHz system bus. See the Intel web site listed below for the most up-to-date list of supported processors.

For information about… Refer to:

Supported processors for the D915PLWD board

http://www.intel.com/design/motherbd/wd/wd_documentation.htm

CAUTION

Use only the processors listed on web site above. Use of unsupported processors can damage the board, the processor, and the power supply.

INTEGRATOR’S NOTE

• Use only ATX12V-compliant power supplies.

• Refer to Table 3 on page 16 for a list of supported system bus frequency and memory speed

combinations.

For information about Refer to

Power supply connectors Section 2.7.2.1, page 47

Page 16

Intel Desktop Board D915PLWD Technical Product Specification

1.4 System Memory

The board has two DIMM sockets and support the following memory features:

• 2.5 V (only) DDR SDRAM DIMMs with gold-plated contacts

• Unbuffered, single-sided or double-sided DIMMs with the following restriction:

Double-sided DIMMS with x16 organization are not supported.

• 2 GB maximum total system memory

• Minimum total system memory: 128 MB

• Non-ECC DIMMs

• Serial Presence Detect

• DDR 400 MHz and DDR 333 MHz SDRAM DIMMs

Table 3 lists the supported system bus frequency and memory speed combinations.

Table 3. Supported System Bus Frequency and Memory Speed Combinations

To use this type of DIMM… The processor's system bus frequency must be…

DDR 400 800 MHz DDR 333

Note: When using an 800 MHz system bus frequency processor, DDR 333 memory is clocked at 320 MHz. This minimizes

(Note)

800 or 533 MHz

system latencies to optimize system throughput.

 NOTES

To be fully compliant with all applicable DDR SDRAM memory specifications, the board 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 4 lists the supported DIMM configurations.

Product Description

1.4.1 Memory Configurations

The Intel 82915PL MCH supports two 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.

Figure 3 illustrates the memory channel and DIMM configuration.

• One parallel ATA IDE connector that supports two devices

• Four serial ATA IDE connectors that support one device per connector

Page 21

Product Description

1.5.2.1 Parallel ATA IDE Interface

The ICH6’s 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 ICH6’s ATA-100

logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.

 NOTE

ATA-66 and ATA-100 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 using the transfer modes.

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 13, page 44

1.5.2.2 Serial ATA Interfaces

The ICH6’s Serial ATA controller offers four independent Serial ATA ports with a theoretical maximum transfer rate of 150 MB/s 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.

1.11.1.1 System States and Power States

Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state.

Table 7 lists the power states supported by the board along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.

1.11.1.2 One-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 W (or less) in S5 (Standby) mode. One-Watt operation applies only to the S5 state when the computer is turned off, but still connected to AC power. One-Watt operation does not apply to the S3 (Suspend to RAM) or S4 (Suspend to disk) states.

Newer energy-efficient power supplies using less than 0.5 W (in Standby mode) may also be needed to achieve this goal.

Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On

NOTE



will enable a wake-up event from LAN in the S5 state.

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.

(Note)

1.11.2 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 connectors

• 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

LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line.

Page 33

Product Description

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.

1.11.2.1 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 13, page 44 The signal names of the main power connector Table 22, page 47

1.11.2.2 Fan Connectors

The function/operation of the fan connectors is as follows:

• The fans are on when the board is in the S0 or S1 state.

• The fans are off when the board is off or in the S3, S4, or S5 state.

• Each fan connector is wired to a fan tachometer input of the hardware monitoring and fan

control ASIC.

• All fan connectors support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed.

• All fan connectors have a +12 V DC connection.

For information about Refer to

The location of the fan connectors and sensors for thermal monitoring Figure 10, page 28 The signal names of the processor fan connector Table 20, page 46 The signal names of the chassis fan connectors Table 21, page 46

1.11.2.3 LAN Wake Capabilities

CAUTION

For LAN wake capabilities, the +5 V standby line for 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 network adapter monitors network traffic at the Media Independent Interface. Upon detecting a

Page 34

Intel Desktop Board D915PLWD Technical Product Specification

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 Conventional bus PME# signal for PCI 2.2 compliant LAN designs

• The onboard LAN subsystem

1.11.2.4 Instantly Available PC Technology

CAUTION

For Instantly Available PC technology, the +5 V standby line for 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 8 on page 32 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 2.2 compliant add-in cards, PCI Express add-in cards, and drivers.

1.11.2.5 Resume on Ring

The operation of Resume on Ring can be summarized as follows:

• Resumes operation from ACPI S1 or S3 states

• Detects incoming call similarly for external and internal modems

• Requires modem interrupt be unmasked for correct operation

1.11.2.6 Wake from USB

USB bus activity wakes the computer from ACPI S1 or S3 states.

NOTE



Wake from USB requires the use of a USB peripheral that supports Wake from USB.

1.11.2.7 Wake from PS/2 Devices

PS/2 device activity wakes the computer from an ACPI S1 or S3 state.

Page 35

Product Description

1.11.2.8 PME# Signal Wake-up Support

When the PME# signal on the PCI Conventional bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).

1.11.2.9 WAKE# Signal Wake-up Support

When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state.

1.11.2.10 +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 11 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.

2.6 PCI Conventional* Interrupt Routing Map

This section describes interrupt sharing and how the interrupt signals are connected between the PCI Conventional bus connectors and onboard PCI Conventional devices. The PCI Conventional specification describes how interrupts can be shared between devices attached to the PCI Conventional 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 Conventional device should not share an interrupt with other PCI Conventional devices. Use the following information to avoid sharing an interrupt with a PCI Conventional add-in card.

PCI Conventional 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 ICH6 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI Conventional interrupt sources either onboard or from a PCI Conventional add-in card connect to one of these PIRQ signals. Some PCI Conventional interrupt sources are electrically tied together on the board and therefore share the same interrupt. Table 14 shows an example of how the PIRQ signals are routed.

PIRQA PIRQB PIRQC PIRQD PIRQE PIRQF PIRQG PIRQH

NOTE

In PIC mode, the ICH6 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 13 for the allocation of PIRQ lines to IRQ signals in APIC mode.

PCI interrupt assignments to the USB ports, Serial ATA ports, and PCI Express ports are dynamic.

2.7 Connectors

CAUTION

Only the following connectors have overcurrent protection: back panel USB, front panel USB, and PS/2. The other internal connectors 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 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. The connectors can be divided into these groups:

• Back panel I/O connectors

• Component-side I/O connectors (see page 44)

2.7.1 Back Panel Connectors

2.7.2.1 Power Supply Connectors

The board has three 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.

• ATX12V 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.

2.7.2.2 Add-in Card Connectors

The board has the following add-in card connectors:

• PCI Express x16: one connector supporting simultaneous transfer speeds up to 8 GBytes/sec.

• PCI Express x1: two PCI Express x1 connectors. The x1 interfaces support simultaneous

transfer speeds up to 500 MBytes/sec.

• PCI Conventional (rev 2.3 compliant) bus: four PCI Conventional bus add-in card connectors.

The SMBus is routed to PCI Conventional bus connector 2 only (ATX expansion slot 6). 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 boards. 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.

2.7.2.3 Auxiliary Front Panel Power/Sleep LED Connector

Pins 1 and 3 of this connector duplicate the signals on pins 2 and 4 of the front panel connector.

2.10 Electrical Considerations

2.10.1 DC Loading

Table 29 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.

Table 29. DC Loading Characteristics

DC Current at: Mode DC Power +3.3 V +5 V +12 V -12 V +5 VSB

Minimum loading 200.00 W 3.30 A 10.00 A 900 A 0.03 A 0.80 A Maximum loading 300.00 W 6.00 A 14.00 A 16.00 A 0.10 A 1.40 A

2.10.2 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 the board is as follows: a fully loaded D915PLWD board (all six expansion slots filled and the PCI Express x16 filled) must not exceed 14 A.

Page 56

Intel Desktop Board D915PLWD Technical Product Specification

2.10.3 Fan Connector Current Capability

CAUTION

The processor fan must be connected to the processor fan connector, not to a chassis fan connector. Connecting the processor fan to a chassis fan connector may result in onboard component damage that will halt fan operation.

Table 30 lists the current capability of the fan connectors.

Table 30. Fan Connector Current Capability

Fan Connector Maximum Available Current

Processor fan 1000 mA Front chassis fan 600 mA Rear chassis fan 600 mA

2.10.4 Power Supply Considerations

CAUTION

The +5 V standby line for 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 29 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 following recommendations found in the indicated

sections of the ATX form factor specification.

• The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2)

• The current capability of the +5 VSB line (Section 4.2.1.2)

• All timing parameters (Section 4.2.1.3)

• All voltage tolerances (Section 4.2.2)

Page 57

Technical Reference

2.11 Thermal Considerations

CAUTION

A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a requirement. Use a processor heatsink that provides omni-directional airflow (similar to the type shown in Figure 19) to maintain required airflow across the processor voltage regulator area.

OM16996

Figure 19. Processor Heatsink for Omni-directional Airflow

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 2.13.

Page 58

Intel Desktop Board D915PLWD Technical Product Specification

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 voltage regulator area (item A in Figure 20) can reach a temperature of up to 85
