Desktop Board Features

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 Desktop Board supports the following memory and interface:
•
•
•
•

Four 240-pin Double Data Rate 3 (DDR3) SDRAM Dual Inline Memory Module
(DIMM) sockets with gold-plated contacts arranged in two channels
2133 MHz to 1066 MHz DDR3 SDRAM Memory Modules
Support for single- and dual-channel memory interleaving
Unbuffered, non-registered single- or double-sided DIMMs with a voltage rating of
1.65 V or less

CAUTION
Using a DIMM with a voltage rating higher than 1.65 V may damage the
processor.
•
•
•

Non-ECC DDR3 memory
Serial Presence Detect (SPD) memory only
Up to 32 GB maximum total system memory using 8 GB 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.

Intel Desktop Board DZ68BC Product Guide

Intel® Z68 Express Chipset
The Intel Z68 Express Chipset consists of the Intel Z68 PCH. The Intel Z68 PCH
includes Intel Rapid Storage Technology and Intel Smart Response Technology.

Intel® Rapid Storage Technology
Intel Rapid Storage Technology version 10.6 enables Intel Smart Response Technology
and full Serial ATA (SATA) interface speed up to 6 Gb/s to support next-generation
Solid State Drives (SSDs) or traditional Hard Disk Drives (HDDs). Intel Rapid Storage
Technology 10.6 also adds support for greater than 2.2 TB HDDs in a RAID
configuration.

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.
For more information on Intel Smart Response Technology refer
to http://download.intel.com/design/flash/nand/325554.pdf or download the user
guide at http://www.intel.com/support/motherboards/desktop/dz68db/sb/CS032499.htm?wapkw=(smart+response)

Realtek ALC892 codec

The subsystem has the following headers and connectors:
•
•
•
•

Back panel audio connectors, including an S/PDIF out optical port.
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
Front panel audio header that supports Intel HD Audio and AC ‘97 Audio. This
header provides mic in and line out signals for front panel audio connectors.
An onboard S/PDIF output header

Desktop Board Features

Desktop Board Features

BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI/PCI Express and SATA auto-configuration utilities. The BIOS is stored in a Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 67.

Serial ATA Auto Configuration
If you install a Serial ATA 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
Serial ATA. You can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.

PCI* and PCI Express* Auto Configuration
If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express
auto-configuration 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/PCI Express add-in card.

Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
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 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.

Related Links:
For instructions on resetting the password, go to Clearing Passwords on page 59.

Intel Desktop Board DZ68BC Product Guide

Back to BIOS Button
The back panel Back to BIOS button (Figure 3, A) duplicates the functionality of the
BIOS configuration jumper (see Setting the BIOS Configuration Jumper on page 58)
with the following exceptions:
•
•
•

It can only be used to force the board to power on to the BIOS Maintenance Menu
using default values but it will retain all previously saved changes.
It cannot be used to override passwords set in the BIOS.
It cannot be used to invoke BIOS recovery mode.

The button glows red when it is activated.

NOTE
Using the Back to BIOS button does not set the board to the factory BIOS
defaults. To restore settings to the factory defaults, use the key once
BIOS setup mode is active.

Power Management Event signal (PME#) wakeup support
WAKE# signal wake-up support
Wake from Consumer IR
Wake from serial port

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.

Intel Desktop Board DZ68BC Product Guide

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 three power connectors. See Figure 27 on page 57 for the
location of the power connectors.

Fan Headers
The function/operation of the fans is as follows:
•
•
•
•
•

The fans are on when the computer 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 of the hardware monitoring and
control device.
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.

The Desktop Board has a 4-pin processor fan header and three 4-pin chassis fan
headers.

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.

Desktop Board Features

Instantly Available PC Technology
CAUTIONS
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.
Power supplies used with this Desktop Board must be able to provide enough standby
current to support the standard Instantly Available (ACPI S3 sleep state) configuration.
If the standby current necessary to support multiple wake events from the PCI and/or
USB buses exceeds power supply capacity, the Desktop Board may lose register
settings stored in memory.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep state. While in the S3 sleep state, the computer will appear to be off. If
the computer has a dual-colored power LED on the front panel, the sleep state is
indicated by the LED turning amber. When signaled by a wake-up device or event, the
computer quickly returns to its last known awake 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.

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 4, 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.

Intel Desktop Board DZ68BC Product Guide

Figure 4. Location of the Standby Power Indicator
For more information on standby current requirements for the Desktop Board, refer to
the Technical Product Specification
at http://support.intel.com/support/motherboards/desktop/

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.

PME# Signal Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an
ACPI S3, S4, or S5 state.

WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S3, S4, or S5 state.

Desktop Board Features

Wake from Consumer IR
Consumer IR device activity wakes the computer from an ACPI S3, S4, or S5 state.

Wake from Serial Port
Serial port activity wakes the computer from an ACPI S3, S4, or S5 state.

Consumer IR (CIR) Headers
The Desktop Board has two CIR headers: the input or receiver header (Figure 24, E)
and the output or emitter header (Figure 24, F). The receiver header consists of a
filtered translated infrared input compliant with Microsoft CIR specifications and a
“learning” infrared input. The learning input is 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 computer can use
to emulate “learned” infrared commands in order to control external electronic
hardware.

NOTE
The Consumer IR option must be enabled in the system BIOS before it can
function. Press at boot to enter the system BIOS, and go to Advanced >
Peripheral Configuration > Enhanced Consumer IR, and set this option to
Enabled.

3 Updating the BIOS
The BIOS Setup program can be used to view and change the BIOS settings for the
computer. You can access the BIOS Setup program by pressing the F2 key after the
Power-On Self-Test (POST) memory test begins and before the operating system boot
begins.
This chapter tells you how to update the BIOS by either using the Intel Express BIOS
Update utility or the Intel® Flash Memory Update Utility, and how to recover the BIOS
if an update fails.

Updating the BIOS with the Intel® Express
BIOS Update Utility
With the Intel Express BIOS Update utility you can update the system BIOS while in
the Windows environment. The BIOS file is included in an automated update utility
that combines the functionality of the Intel Flash Memory Update Utility and the ease
of use of Windows-based installation wizards.
To update the BIOS with the Intel Express BIOS Update utility:
