Hyper-Threading
Hyper-Threading is an Intel® technology that can enhance overall computer performance by allowing one physical processor to function as two logical
processors, capable of performing certain tasks simultaneously. It is recommended that you use the Microsoft® Windows® XP Service Pack 1 (SP1) or higher
operating system because Windows XP is optimized to take advantage of Hyper-Threading technology. While many programs can benefit from HyperThreading, some programs have not been optimized for Hyper-Threading and may require an update from the software manufacturer. Contact the software
manufacturer for updates and information about using Hyper-Threading with your software.
To determine if your computer is using Hyper-Threading technology:

Click the Start button, right-click My Computer, and then click Properties.

Click Hardware and click Device Manager.

In the Device Manager window, click the plus (+) sign next to the processor type. If Hyper-Threading is enabled, the processor is listed twice.

You can enable or disable Hyper-Threading through system setup (see System Setup).

Power Management
Your computer can be set to use less power when you are not working. You control the power usage through the operating system installed on your computer
and certain option settings in system setup (see System Setup). These periods of reduced power are called "sleep modes."

NOTE: All components installed in the computer must support the hibernate and/or standby mode feature(s) and have the appropriate drivers loaded to
enter either of these sleep modes. For more information, see the manufacturer's documentation for each component.
l

Standby. In this sleep mode, power is reduced or turned off for most components, including the cooling fans. However, system memory remains active.

Hibernate. This sleep mode reduces power consumption to a minimum by writing all data in system memory to a hard drive and then removing system
power. Waking up from this mode restarts the computer, and the memory contents are restored. Operation then resumes where the computer left off
when it entered the hibernation mode.

Shutdown. This sleep mode removes all power from the computer except a small auxiliary amount. As long as the computer remains connected to an
electrical outlet, it can be automatically or remotely started. For example, the Auto Power On option in system setup allows the computer to
automatically start at a specified time (see System Setup). Also, your network administrator can remotely start your computer using a power
management event such as Remote Wake Up.

The following table lists the sleep modes and the methods you can use to wake the computer from each mode.

Your computer supports:
l

One SATA (serial ATA) hard drive

One optional floppy drive

One optional CD or DVD drive

1 CD/DVD drive
2 floppy drive
3 hard drive

General Installation Guidelines

Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board.

Drive Interface Connectors

IDE Drive Connector Serial ATA Connector

1 colored stripe on IDE cable
2 interface cable connector
3 interface connector

Connect an IDE CD/DVD drive to the connector labeled "IDE" on the system board. Connect a SATA CD/DVD drive to the connector labeled "SATA1." SATA hard
drives should be connected to the connectors labeled "SATA0" or "SATA1" on the system board. To locate system board connectors, see System Board
Components.

IDE Drive Addressing
When you connect two IDE devices to a single IDE data cable and configure them for the cable select setting, the device attached to the last connector on the
data cable is the master or boot device (drive 0), and the device attached to the middle connector on the data cable is the slave device (drive 1). See the drive
documentation in your upgrade kit for information on configuring devices for the cable select setting.

Power Cable Connectors

IDE Drive Power Connector

Serial ATA Power Connector

1 power cable
2 power input connector

Connecting and Disconnecting Drive Cables
Most connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other connector.
Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe along one edge of the IDE cable—SATA cables do not use a colored
stripe) goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on
the board or card.
When removing an IDE data cable, grasp the colored pull-tab and pull until the connector detaches. When connecting and disconnecting a SATA data cable,
hold the cable by the black connector at each end.
NOTICE: When you connect an IDE data cable, do not place the colored stripe away from pin 1 of the connector. Reversing the cable prevents the drive
from operating and could damage the controller, the drive, or both.

video mode — A mode that describes how text and graphics are displayed on a monitor. Graphics-based software, such as Windows operating systems,
displays in video modes that can be defined as x horizontal pixels by y vertical pixels by z colors. Character-based software, such as text editors, displays in
video modes that can be defined as x columns by y rows of characters.
video resolution — See resolution.
virus — A program that is designed to inconvenience you or to destroy data stored on your computer. A virus program moves from one computer to another
through an infected disk, software downloaded from the Internet, or e-mail attachments. When an infected program starts, its embedded virus also starts.
A common type of virus is a boot virus, which is stored in the boot sectors of a floppy disk. If the floppy disk is left in the drive when the computer is shut down
and then turned on, the computer is infected when it reads the boot sectors of the floppy disk expecting to find the operating system. If the computer is
infected, the boot virus may replicate itself onto all the floppy disks that are read or written in that computer until the virus is eradicated.
V — volt — The measurement of electric potential or electromotive force. One V appears across a resistance of 1 ohm when a current of 1 ampere flows
through that resistance.

W
W — watt — The measurement of electrical power. One W is 1 ampere of current flowing at 1 volt.
WHr — watt-hour — A unit of measure commonly used to indicate the approximate capacity of a battery. For example, a 66-WHr battery can supply 66 W of
power for 1 hour or 33 W for 2 hours.
wallpaper — The background pattern or picture on the Windows desktop. Change your wallpaper through the Windows Control Panel. You can also scan in

your favorite picture and make it wallpaper.
WLAN — wireless local area network. A series of interconnected computers that communicate with each other over the air waves using access points or
wireless routers to provide Internet access.
write-protected — Files or media that cannot be changed. Use write-protection when you want to protect data from being changed or destroyed. To writeprotect a 3.5-inch floppy disk, slide its write-protect tab to the open position.
WWAN — wireless wide area network. A wireless high-speed data network using cellular technology and covering a much larger geographic area than WLAN.
WXGA — wide-aspect extended graphics array — A video standard for video cards and controllers that supports resolutions up to 1280 x 800."

X
XGA — extended graphics array — A video standard for video cards and controllers that supports resolutions up to 1024 x 768.

Z
ZIF — zero insertion force — A type of socket or connector that allows a computer chip to be installed or removed with no stress applied to either the chip or
its socket.
Zip — A popular data compression format. Files that have been compressed with the Zip format are called Zip files and usually have a filename extension
of .zip. A special kind of zipped file is a self-extracting file, which has a filename extension of .exe. You can unzip a self-extracting file by double-clicking it.
Zip drive — A high-capacity floppy drive developed by Iomega Corporation that uses 3.5-inch removable disks called Zip disks. Zip disks are slightly larger than
regular floppy disks, about twice as thick, and hold up to 100 MB of data.

Dell™ OptiPlex™ 320 User's Guide
DDR2 Memory Overview
Addressing Memory With 4-GB Configurations (32-bit Operating Systems Only)
Removing Memory
Installing Memory
For information on the type of memory supported by your computer, see the "Memory" section of the specifications for your computer:
l

Mini Tower Computer Specifications

Desktop Computer Specifications
NOTICE: Before you install new memory modules, download the most recent BIOS for your computer from the Dell Support website at
support.dell.com.

DDR2 Memory Overview
NOTICE: Do not install ECC memory modules. Doing so may cause the system not to boot or affect performance.

If the DDR2 memory modules are not installed with the same amount of memory in each channel, the computer will continue to operate, but with a slight
reduction in performance. See the label in the corner of the module to determine the module's capacity.

NOTE: Always install DDR2 memory modules in the order indicated on the system board.

Be sure to install a single memory module in DIMM1, the connector closer to the processor, before you install a module in the other connector.
The recommended memory configurations are:
l

A pair of matched memory modules installed in connectors DIMM1 and DIMM2
or

A memory module installed in connector DIMM1

Addressing Memory With 4-GB Configurations (32-bit Operating Systems Only)
This computer supports a maximum of 4 GB of memory when you use two 2-GB DIMMs. Current 32-bit operating systems, such as Microsoft® Windows® XP,
can use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than that installed. Certain
components within the computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer
memory.
NOTE: If you use a 64-bit operating system, the entire memory range is available to the operating system.

The following components require memory address space:
l

System ROM

APICs

Integrated PCI devices, such as network connectors

PCI cards

Graphics cards

PCI Express cards (if applicable)

At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required.
The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.
l

If the total installed computer memory is less than the usable space, all installed computer memory is only available for use by the operating system.

If the total installed computer memory is equal to or greater than the usable address space, a portion of installed memory is not available for use by

the operating system.

Removing Memory
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that
you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module.
Otherwise, your computer may not start properly.
NOTE: Memory purchased from Dell is covered under your computer warranty.

Follow the procedures in Before You Begin.

Carefully press out the securing clip at each end of the memory module connector.

Reinstalling Drivers and the Operating System
Dell™ OptiPlex™ 320 User's Guide
Drivers
Using Microsoft® Windows® XP System Restore
Reinstalling Microsoft Windows XP
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: You must use Microsoft® Windows® XP Service Pack 1 or later when you reinstall the Microsoft Windows XP operating system.
NOTE: If you installed a unique image on your computer or if you had to reinstall your operating system, run the DSS utility. DSS is available on your
optional Drivers and Utilities CD (Resource CD) and at support.dell.com.

Drivers

What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.
A driver acts like a translator between the device and any other programs that use the device. Each device has its own set of specialized commands that only
its driver recognizes.
Dell ships your computer to you with required drivers already installed—no further installation or configuration is needed.
NOTICE: The optional Drivers and Utilities CD (Resource CD) may contain drivers for operating systems that are not on your computer. Ensure that you
are installing software appropriate for your operating system.
Many drivers, such as the keyboard driver, come with your Microsoft Windows operating system. You may need to install drivers if you:
l

Upgrade your operating system.

Reinstall your operating system.

Connect or install a new device.

Identifying Drivers
If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver.

Under Pick a Category, click Performance and Maintenance.

Click System.

In the System Properties window, click the Hardware tab.

Click Device Manager.

Scroll down the list to see if any device has an exclamation point (a yellow circle with a [!]) on the device icon.
If an exclamation point is next to the device name, you may need to reinstall the driver or install a new driver (see Reinstalling Drivers and the Operating
System).

Reinstalling Drivers and Utilities
NOTICE: The Dell Support website at support.dell.com and your Drivers and Utilities CD (Resource CD) provide approved drivers for Dell™ computers. If
you install drivers obtained from other sources, your computer might not work correctly.
NOTE: The Drivers and Utilities CD (Resource CD) is optional, and as such, may not ship with certain computers.

Using Windows XP Device Driver Rollback
If a problem occurs on your computer after you install or update a driver, use Windows XP Device Driver Rollback to replace the driver with the previously

installed version.

Click System.

In the System Properties window, click the Hardware tab.

Click Device Manager.

Right-click the device for which the new driver was installed and click Properties.

Click the Drivers tab.

Click Roll Back Driver.

If Device Driver Rollback does not resolve the problem, then use System Restore (see Enabling System Restore) to return your computer to the operating state
that existed before you installed the new driver.

Using the Optional Drivers and Utilities CD
If using Device Driver Rollback or System Restore (see Using Microsoft® Windows® XP System Restore) does not resolve the problem, then reinstall the driver
from the Drivers and Utilities CD (also known as the Resource CD).
NOTE: The Drivers and Utilities CD (Resource CD) is optional, and as such, may not ship with all computers.
NOTE: To access device drivers and user documentation, you must use the Drivers and Utilities CD (Resource CD) while your computer is running
Windows.

Insert the Drivers and Utilities CD.

To access the help files on the Drivers and Utilities CD, click the question mark button or the Help link at the top of the screen.

Using Microsoft® Windows® XP System Restore
The Microsoft Windows XP operating system provides System Restore to allow you to return your computer to an earlier operating state (without affecting
data files) if changes to the hardware, software, or other system settings have left the computer in an undesirable operating state. See the Windows Help
and Support Center for information on using System Restore. For information about accessing the Windows Help and Support Center, see Finding Information.
