HINT: Hyper-Threading is supported only on computers that have 3.06-GHz microprocessors (or higher) installed.
Hyper-Threading is an Intel� technology that can enhance overall
performance by allowing one physical microprocessor to function as two logical
microprocessors, capable of performing certain tasks simultaneously. It is
recommended that you use the Microsoft� Windows� XP
operating system because Windows XP is optimized to take advantage of
Hyper-Threading technology. While many programs can benefit from Hyper-Threading
technology, 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 on using your software with
Hyper-Threading.
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.
For more information on Hyper-Threading, search the Knowledge Base on the Dell
Support website at support.dell.com.
To enable or disable Hyper-Threading:
Shut down and restart the computer.
When the DELL� logo appears, press <F2> immediately to enter the
system setup program.
If you wait too long and the Microsoft Windows
logo appears, continue to wait until you see the Windows desktop. Then shut
down your computer through the Start menu and try again.
When the system setup program screen appears, highlight CPU Information
and press <Enter>.
When the CPU information screen appears, highlight Hyper-Threading
and press the spacebar on the keyboard to select Enable or Disable.
Press <ESC> to save the setting and exit the CPU
Information
screen.

When the blue DELL™ logo appears, press <F2> immediately.
If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows® desktop. Then shut down your computer and try again.
The system setup program screens display the current configuration information for your computer. Information on the screen is divided into five areas:
Title — The area at the top of all system setup screens that displays your computer's model number.
Computer data — Two boxes below the title that display the system processor, L2 cache, service tag, and the version number of the BIOS.
Options — A scrollable box listing options that define the configuration of your computer (including installed hardware, power conservation, and security features).
Fields to the right of the listed options contain settings or values. The settings and values that you can change are brighter on the screen. All other settings and values are set by the computer and cannot be changed. When <Enter> appears to the right of an option, press <Enter> to access a pop-up menu of additional options.
Key functions — A line of boxes across the bottom of the screen that lists keys and their functions within the system setup program.
Help — Press <F1> for information on the option that is selected (highlighted).
