Other processors may be supported in the future. This board is designed to support processors with a maximum wattage of 95 W Thermal Design Power (TDP). The processors listed above are only supported when falling within the wattage requirements of Intel Desktop Board DZ68DB. See the Intel web site listed below for the most up-to-date list of supported processors.
For information about… Refer to:
Supported processors http://processormatch.intel.com
CAUTION
Use only the processors listed on the web site above. Use of unsupported processors can damage the board, the processor, and the power supply.
NOTE
This board has specific requirements for providing power to the processor. Refer to Section 2.5.1 on page 55 for information on power supply requirements for this board.
1.4.1 PCI Express x16 Graphics
The Intel Core i7, Intel Core i5, and Intel Core i3 processors in an LGA1155 socket support discrete add in graphics cards via the PCI Express 2.0 x16 graphics connector:
• Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (500 MB/s) per lane. 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 GEN2 mode.
• Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (250 MB/s) per lane. 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 GEN1 mode.

Intel Desktop Board DZ68DB Technical Product Specification
1.5 System Memory
The board has four DIMM sockets and supports the following memory features:
• 1.5 V DDR3 SDRAM DIMMs with gold plated contacts, with the option to raise the
voltage to support higher performance DDR3 SDRAM DIMMs.
• Support for 1.35V Low Voltage DDR3 (new JEDEC specification)
• Two independent memory channels with interleaved mode support
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMs with x16 organization are not supported.
• 32 GB maximum total system memory (with 4 Gb memory technology). Refer to
Section 2.1.1 on page 39 for information on the total amount of addressable memory.
• Minimum recommended total system memory: 512 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR3 1333 MHz and DDR3 1066 MHz SDRAM DIMMs
NOTE
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 3 lists the supported DIMM configurations.

Product Description
1.5.1 Memory Configurations
The Intel Core i7, Intel Core i5, and Intel Core i3 processors in the LGA1155 socket support 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.

Intel Desktop Board DZ68DB Technical Product Specification
Figure 3 illustrates the memory channel and DIMM configuration.
Figure 3. Memory Channel and DIMM Configuration
NOTE
The Intel Core i7, Intel Core i5, and Intel Core i3 processors require memory to be populated in the DIMM 1 (Channel A, DIMM 1) socket.
For best memory performance always install memory into the blue DIMM memory sockets if only installing two DIMMs in your configuration.

1.8 SATA Interfaces
The board provides six SATA connectors through the PCH, which support one device per connector:
• Two internal SATA 6.0 Gb/s connectors (blue)
• Two internal SATA 3.0 Gb/s connectors (black)
• One internal eSATA 3.0 Gb/s connector (red)
• One eSATA 3.0 Gb/s connector on the back panel for external connectivity (red)
The PCH provides independent SATA ports with a theoretical maximum transfer rate of 6 Gb/s for two ports and 3 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 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/

1.8.1.1 SATA RAID
The board supports Intel Rapid Storage Technology which provides the following RAID (Redundant Array of Independent Drives) levels via the Intel Z68 Express Chipset:
• 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
1.9 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 the 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.
1.10 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.
1.10.1 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 connect to Intel Desktop Boards for this feature to work.
