Memory Configurations

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.
http://www.intel.com/support/motherboards/desktop/sb/cs011965.htm
The Intel 82P43 MCH supports the following types of memory organization:
Memory Configuration Examples
Figure 3 illustrates the memory channel and DIMM configuration.
The DIMM 0 sockets of both channels are blue. The DIMM 1 sockets of both channels are black.
Figure 3. Memory Channel Configuration and DIMM Configuration
Regardless of the memory configuration used (dual channel, single channel, or flex mode), DIMM 0 of Channel A must always be populated. This is a requirement of the Intel Management Engine in ICH10.

PCI Express x16 Graphics

PCI Express 2.0 x16: Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (500 MB/s total). Maximum theoretical bandwidth on interface of 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when operating in x16 mode. Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each direction (1000 MB/s total). Maximum theoretical bandwidth on interface of 8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when operating in x16 mode.
The MCH also supports add in discrete graphics card via the PCI Express 2.0 graphics connector.

PCI Express technology

http://www.pcisig.com
The board supports up to twelve USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH10 provides the USB controller for all ports. The port arrangement is as follows: Six ports are implemented with stacked back panel connectors Six ports are routed to three separate front panel USB headers

Serial ATA Interfaces

The board provides four Serial ATA (SATA) connectors, which support one device per connector.

1.6.3.1

Serial ATA Support
The boards Serial ATA controller offers six 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 six 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 operating system.
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/

1.12.1

Hardware Monitoring and Fan Control
The features of the hardware monitoring and fan control include: Intel Quiet System Technology, delivering acoustically-optimized thermal management Fan speed control controllers and sensors integrated into the ICH10 Four thermal sensors (processor, 82P43 MCH, 82801JIB ICH10, and a remote thermal sensor) Power supply monitoring of five voltages (+5 V, +12 V, +3.3 V, +1.25 V, and +VCCP) to detect levels above or below acceptable values Thermally monitored closed-loop fan control, for all four fans, that can adjust the fan speed according to thermal conditions

The minimum thermal reporting threshold for the MCH is 66 C. The MCH thermal sensor will display 66 C until the temperature rises above this point.

1.13 Power Management

Power management is implemented at several levels, including: Software support through Advanced Configuration and Power Interface (ACPI) Hardware support: Power connector Fan headers LAN wake capabilities Instantly Available PC technology Wake from USB Wake from PS/2 devices Power Management Event signal (PME#) wake-up support

1.13.1

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the board requires an operating system that provides full ACPI support. ACPI features include: Plug and Play (including bus and device enumeration) Power management control of individual devices, add-in boards (some add-in boards may require an ACPI-aware driver), video displays, and hard disk drives Methods for achieving less than 15-watt system operation in the power-on/standby sleeping state A Soft-off feature that enables the operating system to power-off the computer Support for multiple wake-up events (see Table 8 on page 32) Support for a front panel power and sleep mode switch

Add-in Card Connectors
The board has the following add-in card connectors: One PCI Express 2.0 x16 connector: Supports PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (500 MB/s total). The maximum theoretical bandwidth on the interface is 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when operating in x16 mode. Supports PCI Express 2.0 frequency of 2.5 GHz resulting in 5.0 Gb/s each direction (1000 MB/s total). The maximum theoretical bandwidth on the interface is 8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when operating in x16 mode. PCI Express x1: three PCI Express x1 connectors. The x1 interfaces support simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per direction and up to 500 MB/sec concurrent bandwidth. PCI Conventional (rev 2.3 compliant) bus: three PCI Conventional bus add-in card connectors. The SMBus is routed to all PCI Conventional bus connectors. PCI Conventional bus add-in cards with SMBus support can access sensor data and other information residing on the board. All of the PCI Conventional bus connectors are bus master capable. SMBus signals are routed to all PCI Conventional bus connectors. 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.

Note the following considerations for the PCI Conventional bus connectors:

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.

Jumper Block

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 14 shows the location of the jumper block. The jumper determines the BIOS Setup programs mode. Table 27 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.

Mechanical Considerations

Form Factor

The board is designed to fit into an ATX-form-factor chassis. Figure 15 illustrates the mechanical form factor of the board. Dimensions are given in inches [millimeters]. The outer dimensions are 11.60 inches by 9.60 inches [294.60 millimeters by 243.84 millimeters]. Location of the I/O connectors and mounting holes are in compliance with the ATX specification.
Figure 15. Board Dimensions
Electrical Considerations
Power Supply Considerations
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. 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 For example, for a system consisting of a supported 65 W processor (see Section 1.4 on page 14 for a list of supported processors), 1 GB DDR2 RAM, one mainstream video card, one hard disk drive, one optical drive, and all board peripherals enabled, the minimum recommended power supply is 300 W. Table 28 lists the recommended power supply current values. Table 28. Recommended Power Supply Current Values

The maintenance menu is displayed only when the board is in configure mode. Section 2.3 on page 51 shows how to put the board in configure mode.

BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes an 32 Mbit (4096 KB) flash memory device.

Resource Configuration

PCI Autoconfiguration
The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card.

PCI IDE Support

If you select Auto in the BIOS Setup program, the BIOS automatically sets up the PCI IDE connector with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives. The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. To use ATA-66/100 features the following items are required: An ATA-66/100 peripheral device An ATA-66/100 compatible cable ATA-66/100 operating system device drivers

Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive.
System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: BIOS data, such as the BIOS revision level Fixed-system data, such as peripherals, serial numbers, and asset tags Resource data, such as memory size, cache size, and processor speed Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. Additional board information can be found in the BIOS under the Additional Information header under the Main BIOS page.

Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating systems USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2. POST begins. 3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and configure the BIOS Setup program and the maintenance menu. 4. POST completes. 5. The operating system loads. While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. 7. Additional USB legacy feature options can be access by using Intel Integrator Toolkit. To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating systems installation instructions.

During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display.
The POST card must be installed in PCI bus connector 1. The following tables provide information about the POST codes generated by the BIOS. Table 39 lists the Port 80h POST code ranges Table 40 lists the Port 80h POST codes themselves Table 41 lists the Port 80h POST sequence
In the tables listed above, all POST codes and range values are listed in hexadecimal. Table 39. Port 80h POST Code Ranges

1 System resources and hardware (such as PCI and PCI Express*) require physical memory address locations that can reduce available addressable system memory. This could result in a reduction of as much as 1 GB or more of physical addressable memory being available to the operating system and applications, depending on the system configuration and operating system. 2 64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel 64 architecture. Processors will not operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations.
