Product Description
1.5.1 Memory Configurations
The Intel Core i7 and Intel Xeon processors support the following types of memory organization:
• Quad channel (Interleaved) mode. This mode offers the highest throughput for
real world applications.
• Tri channel (Interleaved) mode. Tri channel mode is enabled when the installed
memory capacities of any three DIMM channels are equal.
• Dual channel (Interleaved) mode. 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.

1.6.2 SATA Interfaces
The board provides eight SATA connectors which support one device per connector:
• Two internal SATA 6.0 Gb/s connectors through the PCH (blue)
• Two internal SATA 6.0 Gb/s connectors through a Marvell 88SE9128 controller
(gray)
• Four internal SATA 3.0 Gb/s connectors through the PCH (black) The PCH provides independent SATA ports with a theoretical maximum transfer rate of
6.0 Gb/s for four ports and 3.0 Gb/s for four ports. A point-to-point interface is used for host to device connections.
The underlying SATA functionality is transparent to the operating system. The SATA 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 Microsoft Windows* XP, Windows Vista*, and Windows 7 operating systems.
NOTE
Many SATA 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 SATA connectors Figure 13, page 48

1.6.2.1 SATA RAID
The board supports the following RAID (Redundant Array of Independent Drives) levels via the PCH:
• 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. See your Microsoft Windows XP documentation for more information about installing drivers during installation. Both Microsoft Windows Vista and Microsoft Windows 7 include the necessary RAID drivers for both AHCI and RAID without the need to install separate RAID drivers using the F6 switch in the operating system installation process.

Product Description
1.7 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 via the power supply 5V STBY rail.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be 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 on page 13 shows the location of the battery.
1.8 Legacy I/O Controller
The I/O controller provides the following features:
• Consumer Infrared (CIR) headers
• 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.
1.8.1 Consumer Infrared (CIR)
The Consumer Infrared (CIR) feature is designed to comply with Microsoft Consumer Infrared usage models. Microsoft Windows Vista and Microsoft Windows 7 are the supported operating systems.
The CIR feature is made up of two separate pieces: the receiving (receiver) header, and the output (emitter) header. The receiving header consists of a filtered translated infrared input compliant with Microsoft CIR specifications, and also a “learning” infrared input. This learning input is simply a high pass input which the computer can use to “learn” to speak the infrared communication language of other user remotes. The emitter header consists of two output ports which the PC can use to emulate “learned” infrared commands in order to control external electronic hardware.
Customers are required to buy or create their own interface modules to plug into Intel Desktop Boards for this feature to work.
