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 Hyper-
Threading, 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:
1. Click the Start button, right-click My Computer, and then click Properties.
2. Click Hardware and click Device Manager.
3. 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.

Jumper Settings

NOTICE: Ensure that your computer is turned off and unplugged before you change the jumper settings. Otherwise, damage to your computer or
unpredictable results can occur.
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated.
