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

• Non-ECC DDR3 memory

• Serial Presence Detect (SPD) memory only

• Up to 32 GB maximum total system memory using 8 GB DIMMs

processor.

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

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 <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.

Hardware Management

The hardware management features of Intel Desktop Board DZ68BC 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

22

Desktop Board Features

Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:

• Monitoring of power supply voltages to detect levels above and below acceptable
values

• Smart fan control provided by the legacy I/O controller, delivering acoustically­optimized thermal management. Fan speed controllers and sensors are integrated
into the legacy I/O controller.

• A thermal sensor in the processor

• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust

fan speed

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 24, D
for the

location of the chassis 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)

• Standby Power Indicator LED

• Wake from USB

• 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.

23

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 co

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.

nnectors.

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.

24

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.

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.

26

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.

Onboard Power and Reset Buttons

The lighted Power button on the Desktop Board (Figure 5, A) can be used to turn the
computer on or off. This button duplicates the function of the front panel power
button. To turn off the computer using the onboard Power button, press it for three
seconds.

The Power button stays lit when there is standby power still present on the board.
This is the case even when the computer appears to be off. For example, when this
button is lit, standby power is still present at the memory module sockets and the PCI
bus connectors.

CAUTION

If the AC power has been switched off and the onboard power button 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.
