Product Description

1.5.1 Memory Configurations

The Intel 82P43 MCH 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.

INTEGRATOR’S NOTE

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.

Product Description

1.6 Intel® P43 Express Chipset

The Intel P43 Express chipset consists of the following devices:

• Intel 82P43 Memory Controller Hub (MCH) with Direct Media Interface (DMI)

interconnect

• Intel 82801JIB I/O Controller Hub (ICH10) The MCH component provides interfaces to the CPU, memory, PCI Express, and the

DMI interconnect. The ICH10 is a centralized controller for the board’s I/O paths. The chipset supports the following features:

• USB

• Serial ATA

• Parallel IDE

For information about Refer to

The Intel P43 Express chipset http://www.intel.com/products/desktop/chipsets/index.htm Resources used by the chipset Chapter 2

1.6.1 PCI Express x16 Graphics

The MCH also supports add in discrete graphics card via the PCI Express 2.0 graphics connector.

• 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.

For information about Refer to

PCI Express technology http://www.pcisig.com

Intel Desktop Board DP43TF Technical Product Specification

1.6.2 USB

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

For information about Refer to

The location of the USB connectors on the back panel Figure 9, page 41 The location of the front panel USB headers Figure 10, page 42

1.6.3 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 board’s 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.



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 Refer to

The location of the Serial ATA connectors Figure 10, page 42

Product Description

1.7 Parallel IDE Controller

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.

 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. 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 10, page 42

Intel Desktop Board DP43TF Technical Product Specification

1.8 Real-Time Clock Subsystem

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
