Desktop Board Features
Intel® Z68 Express Chipset
The Intel Z68 Express Chipset consists of the Intel Z68 Platform Controller Hub (PCH).
The PCH is the centralized controller for the board’s I/O paths.
The Intel Z68 PCH provides Intel RST support including Intel RRT and Intel Smart
Response Technology.
Intel® RST
The Intel RST software package provides high-performance SATA and SATA RAID
capabilities for supported operating systems. Intel RST version 10.6 enables Intel
Smart Response Technology, the full SATA interface speed up to 6 Gb/s, and Intel RRT
to support next-generation Solid State Drives (SSDs) or traditional Hard Disk Drives
(HDDs). Intel RST version 10.6 also includes support for larger than 2.2 TB HDDs in a
RAID configuration.
Intel® RRT
Intel RRT uses RAID 1 (mirroring) functionality to copy data from a designated master
drive to a designated recovery drive. The master drive data can be copied to the
recovery drive either continuously or on request:
• Continuous: Changes made to data on the master drive while the system is not
docked are automatically copied to the recovery drive when the system is redocked.
• On request: The master drive data is restored to a previous state by copying the
data on the recovery drive back to the master drive.
Intel® Smart Response Technology
Intel Smart Response Technology supports a single drive volume that combines the
high-performance benefits of SSDs with the large storage capacities of traditional
HDDs to dramatically increase system responsiveness and enable faster boot times.
The two technologies (SSD and HDD) appear as a single C:\ drive letter that provides
you with the familiar storage identifier.
The system automatically learns which files you access frequently and then copies
them from the HDD to the SSD. The next time you request these files, the system
loads them from the fast SSD rather than the slower HDD. For infrequently-used files,
the system loads them from the HDD when you need them.
15
Intel Desktop Board DZ68PL Product Guide
NOTE
The SATA Drive Mode must be set to RAID in the BIOS Setup in order for your
system to use Intel Smart Response Technology. Once RAID is enabled, you can
install the operating system and the Intel Rapid Storage Technology driver. If
the operating system was already installed with the SATA Drive Mode set to
AHCI, you must reinstall the operating system with the SATA Drive Mode set to
RAID. Refer to Section 4, “Configuring Intel Smart Response Technology and
RAID Using Intel

Main Memory
NOTE
To be fully compliant with all applicable Intel ® SDRAM memory specifications, the
board should be populated with DIMMs that support the Serial Presence Detect (SPD)
data structure. If your memory modules do not support SPD, you will see a
notification to this effect on the screen at power up. The BIOS will attempt to
configure the memory controller for normal operation.
The board has four DDR3 DIMM sockets arranged in two channels and supports the
following memory features:
• Two independent memory channels with interleaved mode support
• Support for non-ECC, unbuffered, single-sided or double-sided DIMMs with x8
organization and single-sided DIMMs with x16 organization
• 32 GB maximum total system memory (with 4 Gb memory technology)
• Minimum total system memory: 512 MB
• Serial Presence Detect
• DDR3 1333 MHz and DDR3 1066 MHz SDRAM DIMMs
NOTE
32-bit operating systems are limited to a maximum of 4 GB of memory. These
operating systems will report less than 4 GB because of the memory used by
add-in graphics cards and other system resources.

Desktop Board Features
Graphics Support
The board supports system graphics through a PCI Express 2.0 x16 add-in graphics
card.
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors in an
LGA1155 socket support discrete add-in graphics cards via the PCI Express 2.0 x16
add-in card connector. The board supports the following PCI Express speeds:
• PCI Express 2 frequency of 2.5 GHz which results in 5.0 Gb/s in each direction
(500 MB/s) per lane. The maximum theoretical bandwidth on the interface is
8 GB/s in each direction, simultaneously, when operating in x16 mode.
• PCI Express 1.1 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, when operating in x16 mode.
Audio Subsystem
The board supports Intel High Definition Audio through a Realtek ALC892 audio codec.
The Realtek ALC892-based audio subsystem provides the following features:
• Advanced jack sense for the back panel audio connectors that enables the audio
codec to recognize the device that is connected to an audio port
• Stereo input and output via back panel connectors
• Headphone and Mic in functions for front panel audio connectors
• 97 dB Signal-to-Noise ratio (SNR) playback (DAC) quality and 90 dB SNR recording
(ADC) quality
• Content protection for full-rate loss-less DVD Audio and Blu-ray Disc* audio
content playback (with selected versions of media player software)
The audio subsystem supports the following audio interfaces:
• 7.1 analog back panel audio connectors
• Optical S/PDIF-out back panel audio connector
• S/PDIF-out header with support for optical or coaxial S/PDIF output
• Front panel audio header with support for Intel HD Audio and AC ’97 Audio

The board’s Legacy I/O Controller provides the following legacy features:
• Low pin count (LPC) interface
• Consumer Infrared (CIR) support
• Serial IRQ interface compatible with serialized IRQ support for PCI Conventional
bus systems
• Intelligent power management, including a programmable wake-up event interface
The BIOS Setup program provides configuration options for the Legacy I/O controller.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 61.
SATA Auto Configuration
If you install a SATA device (such as a hard drive) in your computer, the autoconfiguration utility in the BIOS automatically detects and configures the device for
your computer. You do not need to run the BIOS Setup program after installing a
SATA device. You can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.
The BIOS sets SATA to ACHI mode by default.
PCI*/PCI Express Auto Configuration
If you install a PCI Express add-in card in your computer, the PCI Express autoconfiguration utility in the BIOS automatically detects and configures the resources
(IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the
BIOS Setup program after you install a PCI Express add-in card.

be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the supervisor or user
password was entered.
• Setting a user password restricts who can boot the computer. The password
prompt is displayed before the computer is booted. If only the supervisor
password is set, the computer boots without asking for a password. If both
passwords are set, you can enter either password to boot the computer.
For instructions on resetting the password, go to Clearing Passwords on page 53.
Hardware Management
The hardware management features of Intel Desktop Board DZ68PL enable the board
to be compatible with the Wired for Management (WfM) specification. The board has
several hardware management features including the following:
• Fan speed monitoring and control
• Thermal and voltage monitoring
• Chassis intrusion detection
Hardware Monitoring and Fan Speed Control
The features of the hardware monitoring and fan speed control include:
• Smart fan control provided by the legacy I/O controller, delivering acoustically-
optimized thermal management. Fan speed controllers and sensors are integrated
into the legacy I/O controller.
• Thermal sensors in the processor and Intel Z68 PCH, as well as near the processor
voltage regulators and system memory.
• Monitoring of system voltages to detect levels above or below acceptable values
• Thermally monitored closed-loop fan control for all fans that can adjust fan speed
as needed.
Fan Monitoring
Fan monitoring can be observed via the BIOS Setup program, Intel® Desktop Utilities,
or third-party software.

Intel Desktop Board DZ68PL Product Guide
Chassis Intrusion
The board supports a chassis security feature that detects if the chassis cover has
been removed. The security feature uses a mechanical switch on the chassis that can
be connected to the chassis intrusion header on the Desktop Board. See Figure 1 for
the location of the c
hassis intrusion header.
Power Management
Power management is implemented at several levels, including software support
through the Advanced Configuration and Power Interface (ACPI) and the following
hardware support:
• Power connectors
• Fan headers
• LAN wake capabilities
• Instantly Available PC technology (Suspend to RAM)
• +5 V standby power indicator LED
• Wake from USB
• PCI Express WAKE# signal support
• Wake from CIR
Software Support
ACPI
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 Desktop Board requires an
operating system that provides full ACPI support.
Hardware Support
Power Connectors
ATX12V-compliant power supplies can turn off the computer power through system
control. When an ACPI-enabled computer receives the correct command, the power
supply removes all non-standby voltages.
When resuming from an AC power failure, the computer returns to the power state it
was in before power was interrupted (either on or off). The computer’s response can
be set by using the Last Power State feature in the BIOS Setup program’s Boot menu.
The Desktop Board has two power connectors. See Figure 23 on page 51 for the
location of the power co
nnectors.

Desktop Board Features
Fan Headers
The function/operation of the fans is as follows:
• The fans are on when the board is in the ACPI S0 state.
• The fans are off when the computer is in the ACPI S3, S4, or S5 state.
• Each fan header is wired to a tachometer input.
• All fan headers support closed-loop fan control that can adjust the fan speed or
switch the fan on or off as needed.
• All fan headers have a +12 V DC connection (up to 12 V DC when using 3-wire
chassis fans).
• All fan headers are controlled by Pulse Width Modulation.
• The chassis fan header supports linear fan control on 3-wire fans.
The Desktop Board has a 4-pin processor fan header and two 4-pin chassis fan
headers compatible with 4-wire and 3-wire chassis fans.
LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the 5 V standby line for the power supply must be capable
of delivering adequate +5 V standby current. Failure to provide adequate standby
current when using this feature can damage the power supply.
LAN wakeup capabilities enable remote wake-up of the computer through a network.
The LAN subsystem monitors network traffic and upon detecting a Magic Packet*
frame, it asserts a wake-up signal that powers up the computer.
Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the 5 V standby line for the power supply must
be capable of delivering adequate +5 V standby current. Failure to provide adequate
standby current when using this feature can damage the power supply and/or effect
ACPI S3 sleep state functionality.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep state. Instantly Available PC technology enables the board to enter the
ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the computer will
appear to be off (the power supply is off and the front panel power LED will behave as
configured by the BIOS “S3 State Indicator” option). When signaled by a wake-up
device or event, the system quickly returns to its last known wake state.
The Desktop Board supports the PCI Bus Power Management Interface Specification.
Add-in cards that support this specification can participate in power management and
can be used to wake the computer.
23
Intel Desktop Board DZ68PL Product Guide
The use of Instantly Available PC technology requires operating system support and
PCI 2.2 compliant add-in cards, PCI Express add-in cards, and drivers.
+5 V Standby Power Indicator LED
CAUTION
If the AC power has been switched off and the standby power indicator is still lit,
disconnect the power cord before installing or removing any devices connected to the
board. Failure to do so could damage the board and any attached devices.
The Desktop Board’s standby power indicator, shown in Figure 3, is lit when there is
standby power still present on the board even when the computer appears to be off.
For example, when this green LED is lit, standby power is still present at the memory
module sockets and the PCI Express connector.

Desktop Board Features
Wake from USB
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB
and an operating system that supports Wake from USB.
USB bus activity wakes the computer from an ACPI S3 state.
PCI Express WAKE# Signal Wake-up Support
When the WAKE# signal on a PCI Express bus add-in card is asserted, the computer
wakes from an ACPI S3, S4, or S5 state.
Wake from CIR
Consumer IR device activity wakes the computer from an ACPI S3 state.
Speaker
A speaker is mounted on the Desktop Board. The speaker provides audible error code
(beep code) information during the Power-On Self-Test (POST). Refer to Appendix A
for a description of the board’s beep codes.
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 standby power applied by the
power supply.
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 battery 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. Go to page 54 for instructions on how to
repl
ace the battery.
