Purpose of this Utility

The Hyper-Threading Technology Test Utility is provided by Intel Corporation to allow customers with computer systems based on Intel(R) Pentium(R) 4 processors to determine whether or not their desktop or notebook computer systems have the required components to utilize Hyper-Threading Technology and can carry the logo label for the applicable Intel Brand with Platform Requirements (e.g. Intel Pentium 4 Processor with HT Technology). Designed to improve system performance and responsiveness, Hyper-Threading Technology allows a single processor to manage data as if it were two processors by executing multiple instruction threads in parallel.

The following buttons appear on the left side of the display of the test utility:

•	Home – Click on this button to return to the Home page.

•	Run Test – Click on this button to run the test utility.

•	Results – Click on this button to display the results of the test.

•	Updates – Click on this button to download a more recent version of this utility.

•	Help – Click on this button to access the Help menu.

•	About – Click on this button to display the version number of the utility you are using.

Hyper-Threading Technology requires a computer system with an Intel(R) Pentium(R) 4 processor supporting Hyper-Threading Technology and an HT Technology enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. See www.intel.com/info/hyperthreading/ for information including details on which processors support HT Technology.


How the Utility Works

Running the Test

When you click the Run Test button on any screen of the Hyper-Threading Technology Test Utility, the utility begins checking your desktop or notebook computer for the presence of the required components to utilize Hyper-Threading Technology. Specifically, the utility runs the following tests to check for the presence of the required components:

•	Processor Test – Checks for an Intel(R) processor that supports Hyper-Threading Technology

•	Operating System Test – Checks for a supported operating system that includes optimizations for Hyper-Threading Technology

•	Chipset Test – Checks for a Hyper-Threading Technology-enabled chipset

•	BIOS Test – Checks for a system BIOS that supports Hyper-Threading Technology and has it enabled

As the utility runs each component test, the result of the test is displayed. When all of the component tests are complete, if all of the required components are present and enabled, the utility displays either:

•	The logo for Intel(R) Pentium(R) 4 Processor with HT Technology

•	The logo for Intel(R) Pentium(R) 4 Processor with HT Technology Extreme Edition. (See [image] Intel(R) Pentium(R) 4 processor Extreme Edition supporting Hyper-Threading Technology for more information.)

What to Do if a Component Test Fails

If your system did not pass the test for one or more of the required components, the following buttons will appear in the bottom right corner of the display:

•	Display Report – Click on this button to see a list of the components in Notepad format. The report tells you which components passed or did not pass.
NOTE: To print the results, click on File, then Print at the top of the Notepad window.

•	Learn More – Click on this button to access the Intel website for information on what you should do next.

If you expected your system to pass all of the component tests (that is, have all of the components required to utilize Hyper-Threading Technology):

1.	Download an updated version of the test utility (see Downloading Utility Updates below).

2.	Run the test again.

If your system still fails for one or more of the component tests, you need to contact the computer system manufacturer or the place where you purchased your system.

For additional information on the components required to utilize Hyper-Threading Technology, see [image] System Requirements and [image] Supported Operating Systems.

Downloading Utility Updates

If your version of the test utility is more than 90 days old, the utility will prompt you to click on the Updates button on the left side of the display. The utility will then instruct you to click the Check for Updates button to download the latest version of the utility.

NOTE: To obtain the version number of the utility you are using, click the About button on the left side of the display.


Information Verified by the Utility

The Hyper-Threading Technology Test Utility runs through a list of checks first to determine whether the utility can be run on your system, and second to determine whether the required components are present and functional in your system to enable Hyper-Threading Technology.

After the utility has determined that it can be installed, the Home page is displayed. When you click on the Run Test button to start the component tests, the utility checks for the following:

•	Processor – Is the system running a supported Intel(R) Pentium(R) 4 processor?

o	And – Is the system running an Intel Pentium 4 processor with HT Technology Extreme Edition?

•	Operating System– Is the system running a supported operating system that includes optimizations for Hyper-Threading Technology?

•	Chipset – Does the system have a Hyper-Threading Technology enabled chipset?

•	BIOS – Does the system BIOS support Hyper-Threading Technology and have it enabled?

Definitions

BIOS

Stands for basic input/output system. The program a personal computer's microprocessor uses to get the system started. It also manages data flow between the computer's operating system and devices such as the hard disk, video adapter, keyboard, mouse, and printer.

Chipset

A group of integrated circuits (microchips) that are used together to serve a single function and are therefore manufactured and sold as a unit. For example, the Intel(R) 875P and Intel 865PE chipsets support Hyper-Threading Technology.

Hyper-Threading Technology

Enables a single physical processor to appear like two logical processors to an operating system and multi-threaded application. Each logical processor can execute a thread of a multi-threaded program. Designed to improve system performance and efficiency, Hyper-Threading Technology allows a single processor to manage data as if it were two processors by handling data instructions in parallel rather than one at a time.

Intel(R) Pentium(R) 4 Processor Extreme Edition supporting Hyper-Threading Technology

A powerful version of the Intel(R) Pentium(R) 4 processor supporting Hyper-Threading Technology, specifically designed for high-end gamers and computing power users.

Intel(R) Pentium(R) 4 Processor supporting Hyper-Threading Technology

A PC based on the Intel(R) Pentium(R) 4 Processor with HT Technology can enable you to run multiple demanding applications at the same time – making your favorite activity more productive and fun! This groundbreaking technology enables the processor to execute two threads (a part of a program) in parallel – so your software can run more efficiently and you can multitask more effectively than ever before. The Pentium 4 processor supporting Hyper-Threading Technology is designed to deliver performance across applications and usages where end-users can truly appreciate and experience the performance. These applications include Internet audio and streaming video, image processing, video content creation, speech, 3D, CAD, games, multimedia, and multitasking user environments.

Multi-threading

Multitasking within a single program allowing multiple streams of execution to take place at the same time within the same program. Each stream processes a different transaction or message.

Thread

A part of a program that can execute independently of other parts and concurrently with other parts. A thread usually has a many-to-one relationship with processes or applications (multi-threaded applications). Threads are implemented through an operating system’s application programming interfaces.
