1.4 Processor

The board is designed to support the following processor:

 Intel

®

Xeon

®

W3500 series Processor in an LGA1366 socket

In the future, this board may support other processors. This board is designed to

support processors with a maximum wattage of 130 W. The processor listed previously

is only supported when falling within the wattage requirements of the Intel

®

Workstation Board WX58BP. For the most up-to-date list of supported processors,

refer to the following Intel web site: http://processormatch.intel.com

CAUTION

Use only the processors listed on the website mentioned previously. Use of

unsupported processors can damage the board, processor, and power supply.



INTEGRATOR’S NOTE

This board has specific requirements for providing power to the processor. For

information on power supply requirements for this board, refer to Section 2.5.1.

1.5 System Memory

The board has four DIMM sockets and supports the following memory features:

 1.5-V DDR3 SDRAM DIMMs

 Three independent memory channels with interleaved mode support

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

board does not support double-sided DIMMs with x16 organization.

Intel Desktop Board WX58BP Technical Product Specification

14

 16 GB maximum total system memory. For information on the total amount of

addressable memory, refer to Section 2.1.1.

 Minimum total system memory: 1 GB

 Non-ECC DIMMs and ECC DIMMs

 Serial Presence Detect

 DDR3 1333 MHz, DDR3 1066 MHz, and DDR3 800 MHz SDRAM DIMMs

 NOTE

To be fully compliant with all applicable DDR SDRAM memory specifications, you

should populate the board 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 this

may impact the performance and reliability or the DIMMs may not function under the

determined frequency.

and “SS” refers to single-sided memory modules (containing one row of SDRAM).

2. In the fifth column, the number in brackets specifies the number of SDRAM devices on an ECC DIMM.

1.5.1 Memory Configurations

The Intel

®

Xeon

®

W3500 series Processor supports the following types of memory

organization:

 Tri/Dual channel (Interleaved) mode. This mode offers the highest throughput

for “real world” applications. Interleaving reduces overall memory latency by

accessing the DIMM memory sequentially. Data is spread amongst the memory

modules in an alternating pattern.

 Three independent memory channels give two possible modes of interleaving:

 Tri-Channel Mode: Enabled when identical matched memory modules are

installed in each of the three memory channels (blue connectors).

 Dual-Channel Mode: Enabled when two of the blue memory connectors

are populated with matched DIMMs.

 Single-Channel (Asymmetric) Mode: Equivalent to single-channel bandwidth

operation for real world applications. This mode is used when only a single DIMM is

installed or the installed memory modules are not matched. Technology and device

width can vary from one channel to the other.

Figure 3 illustrates the memory channel and DIMM configuration.

1.6 Intel

®

X58 Chipset

The Intel

®

X58 chipset consists of the following devices:

 Intel

®

82X58 IOH with Direct Media Interface (DMI) interconnect

 Intel

®

82801IJR I/O Controller Hub (ICH10R)

The IOH component provides interfaces to the processor and the PCI Express*

graphics connectors. The ICH10R is a centralized controller for the board’s I/O paths.

For information about… Refer to

Intel

®

X58 chipset http://www.intel.com/products/desktop/chipsets/index.htm

Resources used by the chipset Chapter 2

1.6.1 USB

The board supports up to 12 USB 2.0 ports; supports UHCI and EHCI; and uses UHCI-

and EHCI-compatible drivers.

The ICH10R provides the USB controller for all ports. The port arrangement is as

follows:

 Eight ports are implemented with dual, stacked back panel connectors adjacent to

the audio connectors

 Four ports are routed to two separate front panel USB headers

For information about Refer to

Intel Desktop Board WX58BP Technical Product Specification

1.6.2 Serial ATA Interfaces

The board provides six Serial ATA (SATA) connectors, which support one device per

connector.

1.6.2.1 Serial ATA Support

The board’s Serial ATA controller offers six independent Serial ATA ports with a

theoretical maximum transfer rate of 3 Gb/s per port. You can install one device on

each port for a maximum of six Serial ATA devices. Unlike a Parallel ATA IDE, which

supports a master/slave configuration and two devices per channel, a point-to-point

interface is used for host to device connections.

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 Microsoft Windows XP*

and Microsoft Windows Vista* operating systems.



NOTE

Many Serial ATA drives use new low-voltage power connectors and require adapters or

power supplies equipped with low-voltage power connectors.

For more information, see: http://www.serialata.org/

For information about the location of the Serial ATA connectors, refer to Figure 10.

1.6.2.2 Serial ATA RAID

The board supports the following RAID (Redundant Array of Independent Drives)

levels via the ICH10R:

 RAID 0 - Data striping

 RAID 1 - Data mirroring

 RAID 0+1 (or RAID 10) - Data striping and mirroring

 RAID 5 - Distributed parity



NOTE

In order to use supported RAID features, you must first enable RAID in the BIOS.

Also, during Microsoft Windows XP* installation, you must press F6 to install the RAID

drivers. For more information about installing drivers during installation, refer to your

Microsoft Windows XP* documentation.

1.7 Real-Time Clock (RTC) Subsystem

A coin-cell battery (CR2032) powers the real-time clock (RTC) and CMOS memory.

When the computer is not plugged into a wall socket, the battery’s estimated life is

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

25º C with 3.3 VSB applied.

 NOTE

If the battery and AC power fail, the Date and Time values will reset and the user is

notified during POST.

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 shows the location of the battery.

1.8 Legacy I/O Controller

The I/O controller provides the following features:

 Serial IRQ interface compatible with serialized IRQ support for PCI systems

 Intelligent power management, including a programmable wake-up event interface

 PCI power management support

The BIOS Setup program provides configuration options for the I/O controller.

1.9 Audio Subsystem

This board supports the Intel

®

High Definition Audio subsystem based on the Realtek*

ALC889 audio codec. The audio subsystem supports the following features:

 Advanced jack sense for the back panel audio jacks that enables the audio codec to

recognize the device connected to an audio port. The back panel audio jacks are

capable of retasking according to the user’s definition, or can be automatically

switched depending on the recognized device type.

 Stereo input and output for all back panel jacks

 Line out and Mic in functions for front panel audio jacks

 A signal-to-noise (S/N) ratio of 90 dB

1.9.1 Audio Subsystem Software

Audio software and drivers are available from Intel’s website. For information on

obtaining audio software and drivers, refer to Section 1.3.

1.9.2 Audio Connectors and Headers

The board contains audio connectors and headers on both the back panel and the

component side of the board. The component-side audio headers include the following:

 Front panel audio (a 2 x 5-pin header that provides a mic in and line out signals for

front panel audio connectors)

 High Definition (HD) Audio Link header (a 2 x 8-pin header for S/PDIF) used for

HDMI Video cards

 S/PDIF audio connector (1 x 3-pin connector) can be used for HDMI Video cards

that do not work with the HD Audio header

 S/PDIF output between the back panel Optical connector and the internal S/PDIF

header can be selected in BIOS setup

For information about… Refer to
